Everyone knows the saying “an apple a day keeps the doctor away,” but could consuming more servings of produce actually decrease your risk of dying from heart disease?
Although one apple a day is certainly a good start, the latest research suggests that higher fruit and vegetable intake helps decrease your risk of death from heart disease. One study found that each additional serving of fruits and vegetables cut heart disease death by 4 percent. This means that getting 5 servings of fruits and vegetables on a daily basis may decrease your chance of dying from heart disease by 20 percent! Continue reading →
Only 1 percent of adults meet the current guidelines for dietary salt intake, which has led to efforts to reduce sodium in common foods like bread and soup. However, a new research study in over 2,600 seniors suggests that salt intake doesn’t strongly affect heart health in older adults.
Authors of the JAMA Internal Medicine study brought to a simmer the debate over which is better – longstanding federal guidelines to consume no more than 2,300 milligrams of sodium a day, or a new low of 1,500 milligrams or less. Based on information from dietary questionnaires, neither sodium guideline showed remarkable results in protecting from heart attack, stroke, or heart failure.
At first, this looks like good news for those who’ve eaten the same way for a long time and can’t imagine changing what’s on their plate – but the findings don’t necessarily mean patients can leave their doctors’ offices ignoring good advice about salt restriction. Continue reading →
A study out of Cleveland Clinic, recently reported in Journal of the American College of Cardiology, seems to answer the question “Is red meat unhealthy for your heart?”–until you look a little more closely. The study found a strong association between TMAO (trimethylamine oxidase) and severity of heart failure, including an increased risk of death in patients with high TMAO levels. TMAO is a digestion byproduct of bacteria that can live in peoples’ intestines, and has previously been linked to increased risk of heart attack and stroke. Foods such as red meat and eggs are the most common sources of TMAO in the diet.
A look at the study
Some who read this study might be quick to say that heart failure patients should eat less red meat and eggs. However, since the authors did not look at food intake, it is difficult say for sure how TMAO levels in this study related to the dietary patterns of the patients. Some researchers believe that the walls of the intestine become ‘leaky’ when severe heart failure causes fluid congestion there. These leaky walls could let bacteria or their byproducts, like TMAO, into the bloodstream to cause problems. While patients with high TMAO levels in this study were on average older and sicker, most did not appear to have truly severe heart failure. Continue reading →
Hypertension was no match for the DASH diet during a University of Michigan Cardiovascular Center study in which patients with a certain type of heart failure were given heat-and-serve low-sodium (low-salt) meals for three weeks.
Hypertension was no match for the DASH diet during a study in which patients with a certain type of heart failure were given heat-and-serve low-sodium (low-salt) meals for three weeks.
In just 21 days of following a low-sodium Dietary Approaches to Stop Hypertension (DASH) eating plan, patients with “diastolic” heart failure saw a drop in blood pressure similar to taking an anti-hypertension medicine. Some patients were able to cut back on their diuretics and anti-hypertensives.
Diastolic heart failure (a type of heart failure that occurs even though the heart’s muscle-pumping function is not weakened), happens when the heart becomes stiff and does not relax enough between beats. This condition makes up more than half of older adults with heart failure, but has no standard treatment. University of Michigan cardiologist Scott L. Hummel, M.D., M.S, wondered if, based on animal studies, diet could make a big difference for these patients.
