The DASH Diet

Wednesday, November 26th, 2008

A common diet that is often used to manage blood pressure and stop hypertension is the DASH (Dietary Approaches to Stop Hypertension) diet. This diet is rich in fibre and nutrients and contains much more potassium, calcium, and magnesium than the average diet.

Many studies shave shown that in as little as several weeks, people on this diet significantly reduced their blood pressure. Many studies have shown that it is a very effective diet in reducing the risk of diabetes, heart disease, cancer, and osteoporosis.

The key to any new diet success is in not making drastic changes all at one time. It takes time to develop new eating habits and make food choices that make you feel healthier and satisfied.

There are some useful tips that you can use to adjust to the DASH diet:

* Add more fruits and vegetables slowly to your diet. Try replacing fatty snacks with a fruit instead.
* Increase your daily intake of dairy products. If you have trouble digesting dairy products, there are lactose intolerance pills that can aid in digesting these foods.
* Replace enriched flour breads with whole grain bread.
* Choose whole grain cereals without large amounts of additives and sugar.
* Eat fruit flavoured gelatin or dried fruit snacks.
* Add more nuts, seeds, and legumes to your daily diet.
* Eat more of potassium-enriched fruits and vegetables.
* Eat protein foods modestly, with preference given to soy, fish, or poultry.

Are Diuretics The Best Blood Pressure Medication After All?

Friday, November 21st, 2008

If you are being treated for high blood pressure (hypertension) or know someone who is, you should be aware of a study showing that the diuretic chlothalidone was more effective than the angiotensin converting enzyme (ACE) inhibitor lisinopril and the calcium channel blocker (CCB) amlodipine in preventing certain blood pressure-related complications and side effects. The finding is from ALLHAT, a large clinical trial involving 33,357 participants. The results were published in the December 2002 issue of the Journal of the American Medical Association (JAMA) and have sparked quite a debate within the medical community. But what do they mean if you are on treatment or are about to start treatment for high blood pressure?

According to Dr. Curt Furberg, of Wake Forest University Baptist Medical Center, chairman of the ALLHAT study’s steering committee, “The bottom line is ALLHAT has shown that it matters which drug you use to control hypertension.” He stated that, “the preferred drug is the diuretic for 3 reasons. It provides better control of hypertension; it reduces complications from hypertension - particularly heart failure - more effectively; and it is 10 to 20 times less expensive than the other drugs used in the trial.”

Dr. Claude Lenfant, Director of the National Heart, Lung and Blood Institute in the United States, who commented on the ALLHAT results, said “many of the newer drugs were approved because they reduce blood pressure and the risk of heart disease compared to placebo. But they were not tested against each other. So physicians had no sure way of knowing which agent would be more effective - comparatively - as first line therapy. The results of ALLHAT change that.”

The study investigators recommended that doctors begin drug treatment for high blood pressure with a diuretic. However, not everyone can take diuretics, and for those people the investigators suggest a beta-blocker, an ACE inhibitor, like lisinopril, or a CCB be used initially. If your blood pressure is not adequately controlled with a diuretic, a combination of 2 medications is fine, such as an ACE inhibitor and a diuretic. Some of these are available as combination products where 2 medications are combined in one tablet for convenience.

What do the results mean if you are currently taking blood pressure medication(s) other than a diuretic - should you switch? Not necessarily - everyone’s needs are different, and you should never stop taking your medication without checking with your doctor. However, it frequently takes more than one medication to reduce high blood pressure in most people: over 60% of the participants in ALLHAT were on 2 or more blood pressure medications by the end of the study. The take home message is - if your blood pressure is not optimally controlled, it may be worth talking to your doctor about whether a diuretic should be added to your treatment.

Heart Disease Risk Factors

Friday, November 7th, 2008

In order to function properly, your heart needs a large and continuous stream of oxygen-enriched blood, which is supplied directly to your heart muscle through your coronary arteries. If your coronary arteries become clogged, blocked, inflamed, infected, or injured, the blood flow to your heart will be reduced, which can cause injury to your heart muscle and in turn lead to heart disease or cardiovascular disease (CVD). Some of the more common outcomes of heart disease include myocardial infarction, ischemic heart disease and angina, and arrhythmias.

General risk factors for heart disease

Those you can’t change:

* Family history: Genetic predisposition can play a role in the development of heart disease. Your doctor will want to know if you have a family history of heart disease.
* Age: Wear and tear on your body is cumulative. The heart is no exception. The older you are, the more wear and tear your system will have and the greater the risk of your system not functioning as it did when you were younger.

Those you can change:

* Smoking: Smoking reduces the blood’s oxygen level, injures artery walls, and raises your heart rate and blood pressure.
* High-fat diet: Diets high in fat, especially saturated fats, increase the risk of fatty buildup in the arteries.
* High blood cholesterol: Cholesterol is a fatty substance required by your body to make cells. But your body only needs a certain amount. High blood cholesterol can cause arteriosclerosis.
* Physical inactivity: Regular exercise helps to strengthen your heart muscle and keep it in good working order.
* Hypertension or high blood pressure: Hypertension means your blood is hitting too hard against your artery walls. High blood pressure can increase your risk of stroke, aneurysm, heart failure, heart attack, and kidney damage.
* Obesity: Being significantly overweight or obese increases your blood pressure, causing your heart to work too hard on less oxygen, and it increases your risk of diabetes.
* Stress: Stress increases your heart rate and blood pressure, which in turn causes damage to your arteries and heart.
* Diabetes: Men with sugar diabetes (diabetes mellitus) have 3 or 4 times the likelihood of developing atherosclerosis, resulting in angina, heart attacks, strokes, or peripheral vascular disease. Women with diabetes are at an even higher risk - probably 4 times that of non-diabetic women.

“Cholesterol is just one piece of the cardiovascular puzzle. The Life Extension Foundation’s research has found a total of 14 factors that contribute to cardiovascular disease. Several risk factors can be easily helped with vitamins and supplements,” say Steven Joyal, Vice President of Scientific Affairs and Medical Development for the nonprofit Life Extension Foundation.

“For those who take statin medications to lower cholesterol, more isn’t necessary better. People should only take enough to achieve healthy cholesterol levels. It is also important not to let cholesterol levels get too low. Below 160, people experience cognitive impairment and other serious systems.”

1. low Blood EPA/DHA (omega 3 fatty acids)
2. elevated C-reactive protein
3. excess LDL
4. excess insulin
5. low HDL
6. high glucose
7. nitric oxide deficit
