Pharmacotherapy for mild hypertension. (Cochrane Database Syst Rev. 2012 Aug 15;8:CD006742.) “Antihypertensive drugs used in the treatment of adults (primary prevention) with mild hypertension (systolic BP 140-159 mmHg and/or diastolic BP 90-99 mmHg) have not been shown to reduce mortality or morbidity in RCTs. Treatment caused 9% of patients to discontinue treatment due to adverse effects. More RCTs are needed in this prevalent population to know whether the benefits of treatment exceed the harms.”
Stressful Jobs Linked to Heart Woes in Women
Sugary Drinks Linked to Increased Blood Pressure “For every extra sugar-sweetened beverage (355 mL) consumed each day there was a 1.6 mm Hg increase in systolic blood pressure and a 0.8 mm Hg increase in diastolic blood pressure. The link between drinking sugar-sweetened beverages and increased blood pressure was stronger among those who also consumed more sodium. Drinking diet beverages was not associated with increased blood pressure.
Take away. This study doesn't prove that drinking sugar-sweetened beverages increases blood pressure. Still, these beverages provide empty calories that can contribute to weight gain, so it's best to drink them in moderation -- or better yet, drink water or unsweetened beverages instead.”
Sweetened Drinks May Be Linked to Preterm Deliveries “The study, of more than 60,000 pregnant women in Norway, found that those who drank one sugary carbonated or noncarbonated beverage a day were up to 25% more likely to give birth prematurely than those who avoided the sweetened drinks. Artificially sweetened beverages also increased the risk, although to a lesser extent.”
CDC: Only Half Control High Blood Pressure “First, if you have high blood pressure, get motivated. If you can bring your blood pressure down to an ideal level with treatment, then you can enjoy the following health benefits:
Your risk of stroke will be reduced by 30% to 50%.
Your risk of coronary artery disease (causes of angina and heart attack) will be reduced by 20% to 40%.
Your risk of congestive heart failure will be reduced by 40% to 80%.
Your risk of early death will be reduced by 10% to 20%.
Second, know your goal.
For most people with high blood pressure, the goal is pressure lower than 140/90. This means the top number should be lower than 140, the bottom number lower than 90.
For people with diabetes or with chronic (long-lasting) kidney disease, the goal is pressure lower than 130/80.
For people who are elderly, a goal that is a bit higher than 140/90 may be best. Your doctor can help you to pick your target.”
Hockey and Football Concussions: Time for Big Changes, Expert Argues "Helmets don't really help," Johnson says. "A concussion occurs when your skull goes one way and your brain the other. Helmets help with skull fractures, but they don't help for concussions, though players still think they do."
Lifestyle Changes Could Prevent 50% of Common Cancers “Among the "biggest buys" from lifestyle intervention is smoking cessation. "One third of cancer in high-income countries is caused by smoking," Dr. Colditz said. If smoking rates could be reduced to the current levels in Utah [about 11%], the United States could see a 75% reduction in smoking-related cancers in 10 to 20 years — a target that Dr. Colditz feels is feasible in countries where smoking rates have already declined considerably. Similarly, it is estimated that being overweight or obese causes approximately 20% of cancer today. If people could maintain a healthy body mass index (BMI), the incidence of cancer could be reduced by approximately 50% in 2 to 20 years. (A healthy BMI for cancer prevention is from 21 to 23 kg/m², as other speakers pointed out.) Dr. Colditz, among others, estimates that poor diet and lack of exercise are each associated with about 5% of all cancers. Improvement in diet could reduce cancer incidence by 50% and increases in physical activity could reduce cancer incidence by as much as 85% in 5 to 20 years.”
Magnesium intake and incidence of stroke: Meta-analysis of cohort studies (Nutrition, Metabolism & Cardiovascular Diseases 2012) “The present meta-analysis of prospective cohorts suggests that higher magnesium intake is associated with reduced risk of total and ischaemic stroke.”

Resistant Hypertension (J Am Board Fam Med 2012) “Resistant hypertension (RH) is defined as blood pressure above a goal despite adherence to at least 3 optimally dosed antihypertensive medications of different classes, one of which is a diuretic. Evaluation of possible RH begins with an assessment of adherence to medications. The white-coat effect should be ruled out by out-of-office blood pressure monitoring. Obesity, heavy alcohol intake, and interfering substances all contribute to RH. Dietary sodium restriction is an important part of management. RH may be secondary to problems such as renal disease, obstructive sleep apnea, or aldosteronism, and testing for these conditions should be considered. Adequate diuretic treatment is a key part of therapy. … Resistant hypertension is defined as blood pressure (BP) above goal (usually 140/90 mm Hg) despite adherence to a combination of at least 3 optimally dosed antihypertensive medications of different classes, one of which ideally is a diuretic.1 What constitutes an “optimal dose” of medication is presumably at least a moderate dose but not necessarily a maximum dose. Patients requiring =4 antihypertensive medications (even if controlled) are classified as having resistant hypertension. Based on trials during which participants were aggressively titrated to reach target BP, the prevalence of resistant hypertension has been estimated to be 20% to 30%.1 More recently, an analysis of US National Health and Nutrition Examination Survey data suggests that among hypertensive adults treated with medications, approximately 13% have resistant hypertension.2 A recent study of resistant hypertension in Spain found a similar rate of 12%.3 Although this prevalence is lower than initially thought, it is nonetheless quite high and likely will get worse.”

Can Too Much Exercise Be Harmful? “Strive for healthier patterns of exercise, O'Keefe suggests. "Things like gardening, walking, jogging, swimming, yoga," he says. "These are all ideal forms of exercise." Pay attention to intensity. You can take a leisurely all-day bike ride, he says. "Even a century (100-mile) bike ride you can do safely if you don't hammer it." He encourages rest breaks. Lavie concedes that some athletes love the competition and won't give up the long, grueling events. He encourages people to cross train, mixing in several forms of exercise. Runners should consider fitting in some lower-impact exercise such as swimming, biking, or light weight lifting, he says.”

Coronary Artery Calcium Bests Other Risk Markers for CVD Risk Assessment “"If you go to any cardiologist, all that they're doing while you're sitting in front of them is trying to put you into one of three risk categories," lead investigator Dr Joseph Yeboah (Wake Forest University School of Medicine, Winston-Salem, NC) told heartwire. "We know what we should do for low-risk people. We just emphasize lifestyle changes, and most of the time over 10 years nothing happens to them. We know that in high-risk patients, in addition to lifestyle, certain medications work. What we don't know how to do is treat people who fall into the intermediate group. They're in no-man's land. Yet we know a chunk of the people who have heart attacks are within this group. This tells us that there are people who are wrongly put into this category based on current risk tools."”

Fast Food Intake Increases Risk of Diabetes and Heart Disease in Singapore “The latest research, published online July 2 by the American Heart Association's journal Circulation, found that people who consume fast food even once a week increase their risk of dying from coronary heart disease by 20 percent in comparison to people who avoid fast food. For people eating fast food two-three times each week, the risk increases by 50 percent, and the risk climbs to nearly 80 percent for people who consume fast food items four or more times each week. Eating fast food two or more times a week was also found to increase the risk of developing Type 2 diabetes by 27 percent.”
Fighting Alzheimer's Disease With Exercise “The results showed that exercise was more beneficial than diet control in reducing ß-amyloid formation (a defining characteristic of Alzheimer's disease) and restoring memory loss induced by a high-fat diet in these mice. Moreover, Kinoshita's team found that the effect of diet control plus exercise was not significantly different than exercise alone. They attribute the positive effects of exercise to increased degradation of ß-amyloid deposits in the brain. "Based on the results in this research," Kinoshita suggests, "exercise should be given priority to prevent Alzheimer's disease." “

CT Scans Increase Children’s Cancer Risk, Study Finds “CT scans in children can cause small but significant increases in the risk of leukemia and brain cancer, a new study finds. Researchers say the results do not mean that CT scans should be avoided entirely — they can be vitally important in certain situations, like diagnosing severe head injuries — but that the test should be performed only when necessary, and with the lowest possible dose of radiation.
CT, or computed tomography, scans take X-rays from various angles and combine them to create cross-sectional images, and they involve much more radiation than traditional X-ray techniques. Concern about potential harm from the scans has grown as their use has climbed steeply; at least four million children a year receive scans in the United States, and researchers estimate that a third of the scans are unnecessary or could be replaced by safer tests like ultrasound or magnetic resonance imaging, which do not use radiation.”
Diesel Fumes Called Carcinogenic “Diesel engines not only pollute the environment, they also release carcinogenic fumes, according to a panel of experts working for the International Agency for Research on Cancer at the World Health Organization (WHO). Specifically, the exhaust carries toxins that are “definitely a cause of lung cancer,” BBC News reported, and possibly a cause of bladder tumors as well, warranting the move from “probably carcinogenic” to definitely so. The panel drew its evidence from research in miners, railway workers, truck drivers, and other “high-risk” workers, though it emphasized that its findings do not apply only to this group of people, but also to those exposed at lower levels of diesel fumes.”

Hysterectomy may lead to arterial stiffening in postmenopausal women “Estrogen-deficient, postmenopausal women who have had their uterus removed appear to have stiffer arteries compared to similar women who have not had a hysterectomy, according to new research from the University of Colorado School of Medicine. The finding may help explain the greater risk of cardiovascular disease, the leading cause of death in women, reported in previous research. "The message here is that having a hysterectomy may lead to large artery stiffening, which can lead to the development of cardiovascular disease," said Kerrie Moreau, Ph.D., lead author of the study and associate professor of medicine at the University of Colorado School of Medicine. "Knowing this, women who have had a hysterectomy will need to be more vigilant about their cardiovascular health."

High salt intake linked to higher stroke risk “Right now, the AHA suggests that people limit their sodium intake to no more than 1,500 milligrams a day. That's a bit more strict than some other recommendations; the World Health Organization, for example, advises a limit of 2,000 milligrams. But people in the current study -- mainly black and Hispanic New Yorkers -- typically consumed well above those recommendations. They averaged 3,031 milligrams of sodium per day.”
Hypertensive Patients Who Exercise Have Lower Death Risk “According to a presentation at the World Congress of Cardiology, people with hypertension (high blood pressure) could reduce their risk of dying from cardiovascular disease (CVD) or all-cause mortality to a level equivalent a reduction of 40~50 mmHg in blood pressure, simply by exercising.”
Impact of Diastolic and Systolic Blood Pressure on Mortality: Implications for the Definition of “Normal” (Journal of General Internal Medicine 2012) “The mortality rate for individuals over age
50 began to increase in a stepwise fashion with
increasing DBP levels of over 90. However, adjusting
for SBP made the relationship disappear. For individuals
over 50, the mortality rate began to significantly
increase at a SBP=140 independent of DBP. In
individuals=50 years of age, the situation was reversed;
DBP was the more important predictor of mortality.
Using these data to redefine a normal blood pressure as
one that does not confer an increased mortality risk
would reduce the number of American adults currently
labeled as abnormal by about 100 million.
… Our examination of the independent effects of diastolic and systolic blood pressure on mortality confirms a central tenet of the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation and Treatment of High Blood Pressure (JNC 7): systolic blood pressure elevations are more important than diastolic blood pressure elevations in persons over age 50. In fact, in our data, diastolic blood pressures are largely irrelevant in this age group. The situation was reversed in persons age 50 and younger: in whom diastolic blood pressure was the more important predictor of mortality.
Our analysis was also directed at a broader question that we hope JNC 8 will consider in its ongoing deliberations: What is the impact of various definitions of normal blood pressure? The current definition of normal is less than 120/80. Our analysis offers one possible alternative definition: a blood pressure that does not confer an increased mortality risk in a cohort of over 10,000 individuals followed for nearly 20 years. From our data this would mean that abnormal for individuals over age 50 would be a SBP of =140 (independent of DBP), and for individuals less than 50, a DBP?=100 or a SBP?=200. While it should not be viewed as the final word on this topic, we hope it serves as an example of an alternative approach. If nothing else, our findings highlight that the choice about the approach used to define normal blood pressure will impact literally millions of Americans.”

Physical Activity and Breast Cancer Survivorship (Am J Lifestyle Med. 2012) “To help provide guidelines for physical activity counseling with breast cancer survivors, the authors synthesized evidence-based recommendations based on a review of 30 intervention studies. The evidence on (1) type, (2) intensity, and (3) frequency and duration of physical activity for this population was examined. On the basis of the reviewed studies, the authors find that physical activity programs for breast cancer survivors should include aerobic training at least 3 times/wk for 30 minutes, resistance training 2 to 3 times/wk (6–12 exercises), and flexibility training 3 times/wk for 50 to 60 minutes to obtain health benefits. The provision of these recommendations may facilitate effective and consistent delivery of physical activity counseling to breast cancer survivors.”

Mean intake did not differ significantly by action status either overall or by subgroup except for one age category: among patients 65 years and older, mean intake was significantly lower among those who took action (2715±63 mg) than among those who did not (3401±206 mg; P=.0124). Regardless of action, mean intake was well above 1999–2004 recommendations for daily sodium intake and about twice as high as the current recommendation for hypertensive adults (1500 mg).”

Rocks mined to produce phosphate fertilizers also contain varying amounts of cadmium. Cadmium also is found in rechargeable batteries and cigarette smoke. Cadmium enters the body through consumption of contaminated food, water or inhalation of cigarette smoke.”

Arteries Under Pressure Early On: Mice Fed a High-Fat Diet Show Signs of Artery Damage After Only Six Weeks “High fat diets cause damage to blood vessels earlier than previously thought, and these structural and mechanical changes may be the first step in the development of high blood pressure. … The authors conclude: "These results suggest that, at an early stage of obesity, the structural properties of small and large arteries are altered whereas arterial stiffness is only observed in small vessels. This implies that small vessels are targeted earlier compared to large arteries, and this could therefore play a role in the development of hypertension associated with a long-term caloric-enriched diet.”
Impact of lower achieved blood pressure on outcomes in hypertensive patients (Journal of Hypertension 2012) “Achieved SBP 130?mmHg or less is not associated with lower cardiovascular risk than SBP of 131 to 141?mmHg and is associated with a significantly increased risk of death and trend towards increased cardiovascular mortality. These findings support the need for randomized evaluation of treatment to more aggressive vs. conventional SBP targets.”

The within-population day-to-day variation was also greater for sodium than for potassium. Among each population group, a significant correlation was observed between sodium and urine volume, supporting the prior finding of sodium as a determinant of fluid intake in free-living individuals. These data confirm the consistency with the possible role of dietary electrolytes as hypertension risk factors, reinforcing the relevance of potassium in these populations.”

Sleep-Disordered Breathing and Caffeine Consumption: Results of a Community-based Study. (Chest. 2012) “SDB is independently associated with caffeinated soda use in the general community. Identifying excessive caffeine used in SDB has potential significance given the cardiovascular effects of caffeine and untreated SDB.”
Soda Consumption Increases Overall Stroke Risk “Researchers from Cleveland Clinic's Wellness Institute and Harvard University have found that greater consumption of sugar-sweetened and low-calorie sodas is associated with a higher risk of stroke. Conversely, consumption of caffeinated or decaffeinated coffee was associated with a lower risk. … "Soda remains the largest source of added sugar in the diet," said Adam Bernstein, MD, ScD, study author and Research Director at Cleveland Clinic's Wellness Institute. "What we're beginning to understand is that regular intake of these beverages sets off a chain reaction in the body that can potentially lead to many diseases -- including stroke." … In sugar-sweetened sodas, the sugar load may lead to rapid increases in blood glucose and insulin which, over time, may lead to glucose intolerance, insulin resistance, and inflammation. These physiologic changes influence atherosclerosis, plaque stability and thrombosis -- all of which are risk factors of ischemic stroke. This risk for stroke appears higher in women than in men.
In comparison, coffee contains chlorogenic acids, lignans and magnesium, all of which act as antioxidants and may reduce stroke risk. When compared with one serving of sugar-sweetened soda, one serving of decaffeinated coffee was associated with a 10 percent lower risk of stroke.
In addition, study findings show that men and women who consumed more than one serving of sugar-sweetened soda per day had higher rates of high blood pressure and high blood cholesterol and lower physical activity rates. Those who drank soda more frequently were also more likely to eat red meat and whole-fat dairy products. Men and women who consumed low-calorie soda had a higher incidence of chronic disease and a higher body mass index (BMI).”
Statins as a possible cause of inflammatory and necrotizing myopathies (Atherosclerosis 2012) “Statins have recently been associated with a variety of inflammatory myopathies including polymyositis, dermatomyositis, and a necrotizing myopathy. The association of statins with necrotizing myopathy is strengthened by the discovery that the serum of some of these patients contains an anti-HMGCR antibody. This suggests that statins can cause or unmask an immune mediated myopathy.”

Nocturnal blood pressure and cardiovascular disease: a review of recent advances (Hypertension Research 2012) “Among these parameters, there is increasing evidence that the mean nocturnal BP level is the most sensitive predictor of cardiovascular morbidity and mortality. Furthermore, several studies have shown that less nocturnal BP dipping, defined as less nocturnal BP decline relative to daytime BP, or a high night–day BP ratio was associated with poor prognosis irrespective of the 24-hour BP levels. These findings can be interpreted in at least two ways: namely, high nocturnal BP or less nocturnal BP dipping might be not only a potent risk factor for cardiovascular disease (CVD), but also a marker of pre-existing or concurrent diseases that can lead to nocturnal BP elevation.”
Obstructive sleep apnea. (Neurol Int. 2011) “An epidemiological review by Young et al. estimates that 1 in 5 adults has at least mild OSA and 1 in 15 adults has at least moderate OSA.6 Sleep apnea can affect anyone at any age, even children.7,8 OSA is becoming increasingly prevalent. However, because of the lack of awareness by the public and health-care professionals, the vast majority remain undiagnosed and untreated. Data from the Wisconsin sleep cohort study of patients estimate that 93% of women and 82% of men with moderate-to-severe sleep apnea were undiagnosed.9 A follow-up publication from the Wisconsin Cohort Study five years later indicated that the prevalence of OSA in people aged 30–60 years was 9–24% for men and 4–9% for women.10,11 Primary risk factors for OSA include the male gender, those over age 40, overweight persons or recent weight gain, and persons with a large neck size or small chin/jaw (Table 1).12 … The American Academy of Sleep Medicine (AASM) defines an apnea as a cessation in airflow lasting at least 10 sec; apneic episodes can last anywhere from 10 sec to min, and may occur multiple times per hour.46 Hypopnea is defined as a recognizable transient reduction (but not complete cessation) of breathing for at least10 sec. This differs from apnea in that there remains some flow of air. In the context of sleep disorders, a hypopnea event is only considered to be clinically significant if there is a 30% or more reduction in flow with an associated 4% or greater desaturation in O2 level, lasting for 10 seconds or longer, or if it is associated with an arousal or fragmentation of sleep. Apneas and hypopneas are both considered in assessing the severity of a person's sleep disorder.47 … Hypertension that is primarily caused by OSA (in contrast to essential hypertension) is distinctive in that the blood pressure does not drop significantly when the individual is sleeping.59 OSA that remains untreated can also have a negative effect on memory. Research has recently shown that individuals with OSA have mammillary bodies that were nearly 20 percent smaller on MRI.60 This decreased tissue mass may be related to the memory problems seen in chronic OSA.”

Rapid Rise in Blood Pressure Before Midlife May Cause Irreversible Heart Damage “Based on the study findings, Dr. Ghosh said a borderline or pre-hypertensive blood pressure reading (a systolic pressure of 120 to 139 mm Hg or a diastolic pressure from 80 to 89 mm Hg) -- even in your 30s -- should warrant more frequent monitoring so doctors can assess the rate of change in blood pressure. Current guidelines are based on a single, one-off measure of blood pressure and doctors rarely prescribe blood pressure-lowering medications for people in their 30s, as the risk of them having a cardiovascular event in the next 10 years is low.
"If people have a rapid rise in blood pressure, early treatment should be considered, because we know from this study that, 30 years down the line, they're going to have more heart damage than somebody with a slower rise in blood pressure," Dr. Ghosh said. "We're potentially talking about a completely new way of assessing and treating blood pressure in younger people."
The results revealed people who experienced a relatively rapid increase in blood pressure during midlife typically had a larger left ventricle -- an independent risk factor for heart disease and other health problems -- than those whose blood pressure edged up more slowly or later in life. Those taking medication to manage high blood pressure had a larger left ventricle than those with the same blood pressure who had never taken medication, suggesting that treatment in later life did not reverse the consequences of a rapid rise in blood pressure in earlier years.”
Sleeping Too Much or Too Little Can Be Bad for Your Heart“Getting too little sleep -- or even too much -- appears to spell trouble for the heart. New data reveal that adults who get less than six hours of sleep a night are at significantly greater risk of stroke, heart attack and congestive heart failure. Even those who reportedly sleep more than eight hours a night have a higher prevalence of heart problems, namely chest pain (angina) and coronary artery disease, a narrowing of the blood vessels that supply blood and oxygen to the heart, according to research presented March 25 at the American College of Cardiology's 61st Annual Scientific Session.”

Trends in Cardiovascular Health Metrics and Associations With All-Cause and CVD Mortality Among US Adults (JAMA 2012) “The healthy diet score from the AHA ranges from 0 to 5 and is calculated by summing the following components, assigning 1 point each for the consumption of fruits and vegetables (=4.5 cups/d), fish (=two 3.5-oz servings/wk), fiber-rich whole grains (=three 1-oz–equivalent servings/d), sodium (<1500 mg/d), and sugar-sweetened beverages (=36 oz/wk). … Elevated blood pressure, including prehypertension and hypertension, was associated with the largest adjusted PAFs for all-cause and CVD deaths in this cohort (30.4% and 40.6%, respectively). Hypertension affected approximately 68 million individuals in the United States in 2009.27 Studies suggest that for every 10% increase in hypertension treatment, an estimated 14 000 deaths would be prevented annually.28 Although the awareness, treatment, and management of hypertension are extremely important in prevention of CVD incidence and mortality, our results indicated that the desirable level of blood pressure (<120/<80 mm Hg) among the adult population remained unchanged since 1988. In addition to high sodium intake,29 overweight or obesity, lack of physical activity, high alcohol intake, and poor diet are other important modifiable risk factors for elevated blood pressure and hypertension, supporting the importance of primordial prevention of elevated blood pressure through behavioral and policy changes.”
Vitamin D deficiency and supplementation and relation to cardiovascular health (The American Journal of Cardiology 2012) “In conclusion, vitamin D deficiency was associated with a significant risk of cardiovascular disease and reduced survival. Vitamin D supplementation was significantly associated with better survival, specifically in patients with documented deficiency.”
Vitamin D on Trial “The forms of vitamin D that are obtained from foods and supplements (D2 and D3), as well as endogenously upon sun exposure (D3), are biologically inert.
Two hydroxylation reactions are necessary to convert the vitamin to its active form. The first reaction occurs in the liver and converts the vitamin to an intermediate known as 25-hydroxyvitamin D3 (25D), or calcidiol. The second reaction occurs primarily in the kidneys, and results in the vitamin’s active form, 1,25-dihydroxyvitamin D3 (1,25D), or calcitriol. … “In nutrition we talk about maintaining normal adequacy, but some people may require more vitamins than others, and identifying those populations will really be the future of nutrition,” says Milner. “It’s the classic ‘one size does not fit all.’ I’m hoping we can identify biomarkers that tell us who will really benefit, and who doesn’t need to worry.” “

Diabetes Risk from Sitting Around “Dr Thomas Yates who led the study said: "This study provides important new evidence that higher levels of sitting time have a deleterious impact on insulin resistance and chronic low-grade inflammation in women but not men and that this effect is seen regardless of how much exercise is undertaken. This suggests that women who meet the national recommendations of 30 minutes of exercise a day may still be compromising their health if they are seated for the rest of the day.
'It therefore suggests that enabling women to spend less time sitting may be an important factor in preventing chronic disease.'”

Fight Menopause With a Strong Heart “After menopause, women may develop arterial stiffness – marked by increased pulse pressure – according to many studies. Arterial stiffness can make it easier for plaque to build up inside arterial walls, which may result in coronary atherosclerosis, which is a thickening of the artery walls and a precursor to cardiovascular disease, a major cause of death in elderly women.
In the study, researchers administered BH4 oral treatment to 24 women in postmenopause and 9 women in premenopause. BH4 is a naturally occurring chemical that aids in the production of nitric oxide, which is beneficial to arterial health, say the researchers.
Nitric oxide causes arteries to dilate, and without it, arteries can stiffen and cause high blood pressure, thickening of the left ventricle and may increase the risk for heart disease, stroke and dementia, says lead researcher Dr. Kerrie Moreau, associate professor of medicine at the University of Colorado School of Medicine, in a statement. … To prevent vascular health decline, we can intervene with appropriate therapeutic strategies such as exercise, diet and/or hormone therapy, says Moreau.”

High Blood Pressure and the DASH Diet “One step to lower high blood pressure: Incorporate the DASH diet into your lifestyle. Doctors recommend:
Eating more fruits, vegetables, and low-fat dairy foods
Cutting back on foods that are high in saturated fat, cholesterol, and total fat
Eating more whole grain products, fish, poultry, and nuts
Eating less red meat and sweets
Eating foods that are rich in magnesium, potassium, and calcium
The DASH diet, which stands for Dietary Approaches to Stop Hypertension, is an example of such an eating plan. In studies, patients who were on the DASH diet reduced their blood pressure within two weeks. Another diet -- DASH-Sodium -- calls for reducing sodium (salt) to 1,500 mg a day (about 2/3 teaspoon). Studies of patients on the DASH-Sodium plan significantly lowered their blood pressure. … Here are some tips to get you started on the DASH diet:
Add a serving of vegetables at lunch and at dinner.
Add a serving of fruit to your meals or as a snack. Canned and dried fruits are easy to use.
Use only half the butter, margarine, or salad dressing, and use low-fat or fat-free condiments.
Drink low-fat or skim dairy products three times a day.
Limit meat to six ounces a day. Try eating some vegetarian meals.
Add more vegetables, rice, pasta, and dry beans to your diet.
Instead of typical snacks (chips, etc.), eat unsalted pretzels or nuts, raisins, graham crackers, low-fat and fat-free yogurt and frozen yogurt; unsalted plain popcorn with no butter, and raw vegetables.
Read food labels carefully to choose products that are lower in sodium.”

High-Normal Blood Pressure Raises Heart Risks in Men ““Having high blood pressure in middle age is a major risk factor for developing atrial fibrillation later in life, and now new research links high-normal-range blood pressure with an increase in risk.
More than 2 million mostly older Americans have the heart rhythm disorder known as atrial fibrillation, which greatly increases their risk for stroke, heart failure, and death.
Researchers followed about 2,000 Norwegian men for an average of 30 years, during which time 270 developed atrial fibrillation.
Men whose systolic blood pressure (the upper number) was in the high-normal range at the start of the study were 50% more likely than men with normal blood pressure to develop the heart rhythm condition.
An earlier study in women who were followed for an average of 14 years also showed high-normal blood pressure to be associated with a higher risk for atrial fibrillation. … Prehypertension is common in people with metabolic syndrome, which is a group of risk factors associated with an elevated risk for heart disease, stroke, and type 2 diabetes.
“This study is another example of a metabolic syndrome trait being associated with higher [heart disease and stroke] risk,” says AHA spokesman Roger Blumenthal, MD, who directs the Johns Hopkins Ciccarone Preventive Cardiology Center.
Blumenthal says the findings should serve as a wake-up call for those with blood pressure readings in the high-normal range, adding that people with systolic blood pressure readings in the 130s and diastolic readings in the 80s should be counseled to make lifestyle changes that can improve the numbers.
“That means revving up your diet and exercise schedule and losing weight if you are overweight,” he says.
Is the metabolic syndrome caused by a high fructose, and relatively low fat, low cholesterol diet? (Arch Med Sci. 2011) “The metabolic syndrome (MetS) is manifested by a lipid triad which includes elevated serum triglycerides, small LDL particles, and low high-density lipoprotein (HDL) cholesterol, by central obesity (central adiposity), insulin resistance, glucose intolerance and elevated blood pressure, and it is associated with an increased risk of type 2 diabetes and coronary heart disease. We have developed a new hypothesis regarding MetS as a consequence of a high intake in carbohydrates and food with a high glycemic index, particularly fructose, and relatively low intake of cholesterol and saturated fat. … Fructose also leads to increased levels of advanced glycation end products. The macrophages exposed to advanced glycation end products become dysfunctional and, on entry into the artery wall, contribute to plaque formation and thrombosis.”

Missed Naps Could Put Toddlers at Risk for Mood Disorders “Toddlers who miss daytime naps may be at increased risk for mood disorders later in life, a new study indicates. Researchers looked at toddlers aged 30 months to 36 months and found that depriving them of a single daily nap resulted in more anxiety, lower levels of joy and interest, and reduced problem-solving abilities.
"Many young children today are not getting enough sleep, and for toddlers, daytime naps are one way of making sure their 'sleep tanks' are set to full each day," study leader Monique LeBourgeois, an assistant professor in the integrative physiology department at the University of Colorado, Boulder, said in a university news release.
"This study shows insufficient sleep in the form of missing a nap taxes the way toddlers express different feelings, and, over time, may shape their developing emotional brains and put them at risk for lifelong, mood-related problems," she explained.”

Sugary drinks tied to breastfed kids' weight “Babies who were breastfed longest and drank few or no sugary beverages were about half as likely to be obese as kids who weren't breastfed or who consumed the most sugary drinks, in a new study of Hispanic children in southern California. The research, published in the American Journal of Clinical Nutrition, is one of the first looks at the combined effects of breastfeeding and how many sugary drinks, like soda and juice drinks, children consume in the first few years of their lives. Past studies have suggested that breastfeeding is linked to a lower risk of obesity in children; however, Jaimie Davis, the study's lead author and a professor at the University of Southern California, said mothers will also give their babies and toddlers sugary drinks. "What happens is that they're breastfeeding and they're often giving their kids juice or Gatorade," said Davis. "They don't realize it's having the counter effect." “
