Diet for High Blood Pressure

In this present modern society, where we are surrounded by high technologies and sciences, our food habits have also drastically changed. Instead of enjoying and eating natural food items like fruits or vegetables we rely more on burgers, fast foods, cheese etc. Human body can withstand such foods to some extent, but excess intake may lead to obesity or increase in cholesterol level that raises blood pressure and finally invites heart attack or stroke. Indeed there’s great connection with food and blood pressure.

There’s difference in cholesterol level among different countries, which apparently depends on their eating habits and lifestyle. When nation as a whole will switch to less fat or focuses more on exercise, blood cholesterol level will eventually drop and coronary heart rate declines.  One of the best to control blood pressure is to knock out sodium and invite potassium in body. It means avoid food with high sodium and fat level. Rate of heart diseases were found to be less in Italy, France, Greece, japan because their diet includes more of fruits, vegetables, sea woods and olive oil as compared to Americans.  However, it will be wrong to generalise that diet for high blood pressure only means that you have to stick to green leafy stuffs and fruit, you can even control blood pressure by selecting foods which you love , provided it gives good impact on heart. Focus more on quality of life then quantity of life.

Diet for High Blood Pressure

We require complete balance of fat, protein and carbohydrates for staying healthy. Researches have shown that combination of fruits, vegetables, low fat dairy products are good for heart and best option for reducing blood pressure. The medication requirement reduces to large extent if you start healthy diet.

Studies have shown that best diet for high blood pressure patient is Mediterranean diet. Mediterranean diet in general doesn’t helps to lower blood pressure but it reduces chances for heart attacks (myocardial infarction). This diet converts fat calories to carbohydrates, thus reduces extra fat and play effective role in weight loss. One Mediterranean diet involves daily 8 servings of whole grain beans or cereals, 6 servings of fruits, 3 servings of vegetables and 2 servings of low fat dairy products. On a weekly basis, it includes 5-6 servings of fish and seaweeds, 4 poultry products, 2-4 servings of olive oil, nuts and beans, 3 serving of potatoes and 3 servings of eggs. Apart from diet, lifestyle also impacts our heart. Daily morning exercise, red wine in dinner, quitting smoking and alcohol can minimises blood pressure.

One of the biggest studies undertaken to study effect of blood pressure and diet was conducted by US National Institute of health which involves DASH diet, standing for Dietary Approaches to Stop Hypertension. DASH diets incorporates more amount of fruits, vegetables, whole grains, fish, poultry, nuts, legumes and low fat dairy products in order to ensure almost all key nutrients like potassium, magnesium, calcium, fibre and protein are supplied to body. DASH diet supplies 2000 calories per day. This diet was effective in reducing systolic blood pressure by 5.5mmHg and diastolic by 3 mmHg.

Let us now discuss in details various type of foods and health benefits.

Diet for High Blood Pressure : Fruits

Fruits have mysterious power to control blood pressure. The presence of large no of components in fruits like fibres, potassium, calcium, pectin, flavonoids etc. has contributed to its cardio protective action. The fibre level in fruits is higher in comparison to vegetables and cereals.

Diet for High Blood Pressure : Fish & omega-3-fatty acid supplements

Certain cold water fish are rich source of polyunsaturated fatty acids known as omega-3-fatty acid. An omega-3-fatty acid is divided into 3 types- eicosapentanoic acid (EPA), docohexanoic acid (DHA) and alpha linoleic acid (ALA). EPA and DHA are found fishes but ALA is a plant origin components. Omega-3-fatty acid is very famous for its cardiovascular benefits. It prevents formation of blood clots and increases level of HDL cholesterol and at the same time it reduces level of triglycerides (form in which fat is transported from gut to liver) in blood. It brings disturbed heart rhythms to normal and promotes blood flow in arteries by reducing resistance in arteries and thus lowers the blood pressure.

Wild salmon, tuna, mackerel, cod, trout, herring and sardines are among the best source for omega-3-fatty acid. The American Heart Association recommends at least 2 servings of fish per week to sustain the health benefits of fatty acid. Various fish oil supplements are available for people who don’t eat fish.

The characteristic feature of legume is the presence of folate or folic acid (vitamin b complex), which helps in relaxing blood vessels and improves blood flow and thus lowers blood pressure. A daily serving of at least 400 microgram is recommended for its effective action.

Oats : Oats is also rich in magnesium and fibres. Oats lower blood pressure by preventing or slowing down of atherosclerosis which involves formation of plaques in blood vessels. A daily intake of three fourth cup of whole grain oats or at least six serving per week is recommended.

Walnuts: Walnut is an excellent source of alpha linoleic acid (ALA), which is type of omega-3-fatty acid. Even Nuts like pista, pea cans have minute quantities of omega-3-fatty acids, but almonds are deficient of any such compounds.

Flaxseeds and flaxseed oils consists of omega-3-fatty acids.

Certain beans like green soy beans, kidney beans boost up the level of omega-3-fatty acid in body.

Coffee, cola and tea

We already know that caffeine present in coffee, cola, chocolates and tea increases blood pressure to certain extent. Even then almost every community consumes beverages like coffee and tea. Initially caffeine increases blood pressure, but routine drinking develops resistance and then blood pressure is hardly affected by caffeine.

The harmful effects of coffee depend on source and its method of preparation. In France, people prepare coffee, by adding coffee beans into boiling water. Such process leads to release of two chemicals called diterepens which increase LDL cholesterol level. Drip can be used as remedy for such cases as it involves no use of boiling water.

People who love decaffeinated drink should prefer Arabica beans instead of Robusta beans because Robusta beans increase level of LDL cholesterol. More than two servings of coffee decreases blood flow to the heart during exercise. So drink only one cup of coffee before exercising. As caffeine content in teas is less than coffee, so no much harmful effects were observed on tea consumption.

Dark chocolates

Studies have proven dark chocolates lowers cholesterol level in body due to the presence of flavonoids. Darker the chocolates, greater will be the level of flavonoid. Dark chocolates can lower systolic blood pressure by 11.9mmHg and diastolic blood pressure by 8.5mmHg. However this doesn’t mean that you can start daily eating of chocolates because certain drawbacks are also associated with chocolates like100gm of chocolates adds 580 calories and 48gm of fats, out of which 27.5 gm. is saturated fat.

Low fat dairy products

Various low fat dairy products like milk, cheese and yoghurt play an effective role in maintaining blood pressure. At least 3 servings per day are recommended for such products. Moderate amount of fat is essential in such products because helps in increasing bioavaibility of calcium and facilitates its rapid absorption. The potassium and magnesium content in such products helps in lowering blood pressure. Butters and all sorts of cheese except cottage cheese contains large amount of salt. So such products should be avoided by hypertensive patients.

So in the end always try to intake moderate level of any food. It’s not necessary to stop your favorite food items. But do take care of your heart.  Improve lifestyle by regular exercise, meditation and quitting of cigarettes and alcohol.
