DIET
IN HYPERTENSION
Heart
disease covers a range of disorders which affect our arteries,
blood vessels, or the heart, leading to narrowed or blocked
arteries and preventing the heart from pumping blood efficiently,
thereby leading to hypertension. Hypertension
is persistent blood pressure above normal i.e. 140 mm Hg systolic
and 90 mm Hg diastolic.
Some of the common causes for high
blood pressure include:
Ø Positive family history
Ø Overweight and obesity.
Ø High sodium intake in the form of increased salt intake or
processed foods.
Ø Sedentary lifestyle
Ø Excessive alcohol consumption.
Food
is one of the most important elements of life. Not only the
amount of food we eat, but also the different food groups we
eat, make a significant impact on our health. Thus, controlling
diet and lifestyle changes are critical in the effective treatment
of high blood pressure.
Nutrients to fight Hypertension
/ Protective nutrients for hypertension:
Ø Potassium:
Many studies support the fact that regular consumption of potassium
rich foods can help to lower and control blood pressure. Good
sources of potassium include fruits and vegetables like potatoes,
spinach, tomatoes, bananas, oranges and dry fruits.
Ø Calcium:
Calcium is needed for contraction and relaxation of heart muscles,
thereby making it an essential nutrient for fighting hypertension.
Low fat milk, yogurt, green leafy vegetables, almonds and tofu
form some of the good sources for calcium.
Ø Fiber:
High fiber helps to lower systolic and diastolic blood pressure.
Whole cereals and pulses, daals, peas, soybean, fruits and vegetables,
wheat bran, oat bran etc. contribute to increased fiber intake.
Ø W-3 Fats:
Oils rich in PUFAs have been acknowledged to have great health
benefits, these include w-3 fatty acids. Good sources of w-3
fats include mustard oil, wheat, rajmah. Lobia flax seeds, methi
seeds, soybean, and walnuts.
Ø Magnesium:
Magnesium deficiency leads to low levels of calcium and potassium
in the blood as well as changes in the heart and circulatory
system, thus making magnesium an important part of our diet
during hypertension. Whole grains, pulses, daals, spinach, whole
wheat bread, nuts and tofu are some of the good sources of magnesium.
Dietary
Approaches to Stop Hypertension (DASH DIET):
A
large clinical study tested the effect of diet on patients with
elevated Blood Pressure. Participants ate a diet rich in fruits, vegetables, and low fat
dairy products. They avoided red meats, sweets, and sugar
rich drinks. The DASH
diet provided high amounts of fiber, potassium and magnesium.
The study participants exhibited lowered blood pressure and
cholesterol levels.
In
a second study, participants decreased consumption of sodium
and salt. Some participants followed the DASH diet, while remainder
ate typical American diet. Results showed that lowered sodium
intake led to reduced blood pressure levels in both the groups
but the group that followed DASH diet had the most significant
results.
General guidelines for controlling
Blood pressure:
1.
Achieve ideal body weight.
2.
Limit salt intake.
3.
Reduce total fat intake
to not more than 3-4 teaspoons in a day.
4.
Use cold pressed oils
like olive oil, mustard oil etc. or blended oils.
5.
Reduce animal fat intake.
6.
Limit alcohol intake
to not more than 60 ml per day.
7.
Limit intake of caffeine
to not more than 2 cups of tea and 1 cup of coffee.
8.
Use variety of seasonal
fruits and vegetables. Include 6-9 servings of these in the
daily diet. 1 serving is equal to half a cup.
9.
Include herbs, green
and herbal tea, and vegetables like celery, nettle (bichoo booti), lauki juice, cucumber, garlic, green coriander and
parsley as they have diuretic effect, help in urine formation
and control BP.
10.
Foods rich in low fat dairy include yogurt, soy milk, skim milk.
11.
Include soya, nuts, fatty fish, mustard seeds, flaxseeds, fenugreek
Seeds (methre) in the diet
Tips to curtail dietary salt intake:
1.
Reduce salt in cooking
and in recipes to ½ the amount; or omit salt completely and
substitute your own seasoning blend.
2.
Use pure herbs and spices
instead of seasoned salts.
For example, buy garlic powder instead of garlic salt
and onion powder instead of onion salt.
3.
At the table, taste
food before you sprinkle salt on it.
Avoid sprinkling salt on fruits and salads. Remember
that there is no difference between cooked and sprinkled salt.
Also, common salt and rock salt (kala or lahori namak)
both contain similar variety of salt.
4.
Use a salt shaker with
small holes, or cover all but one hole. Gomesia a salt substitute made of sesame seeds and salt is an excellent
seasoning used by the oriental race.
5.
Create your own herb
and spice blend, and put it in your salt shaker instead of salt.
6.
Restrict pickles, pappads
and chutneys to a minimum.
Prepare these at home, using small amounts of salt.
7.
Choose fresh or frozen
unprocessed food preparations over those, that are canned, cured,
smoked or processed. The
latter contain too much of salt for preservation and flavour.
8.
Sausages, ham and bacon
are particularly rich in salt.
These should be eaten sparingly.
9.
Avoid canned or bottled
sauces such as chilli, tomato.
Make your own sauces using your favorite salt substitute
or herb/spice blend. Use
only low salt soy sauce and dilute with lemon juice.
10
Avoid fast foods, store
bought baked goods, spaghetti sauces, pizzas etc.
11
Avoid dishes, which
contain agino-motto, a taste enhancer, often used in Chinese
foods.

Prefer bakery products
using yeast over those prepared with baking soda.
13
When eating out, ask
your waiter to have your food prepared without adding salt.
