Polyunsaturated Fatty Acid (PUFA) - The Fatty Acids that Help Prevent High Blood Pressure
Fats in our diet are also important since they provide the energy to help us keep our body temperature and protect some of our body tissues and organs. They are also important in the absorption of the fat-soluble vitamins A, D, E, and K.
However, we have to distinguish between saturated fats and polyunsaturated fats in as much the former tends to increase blood cholesterol levels while the latter, the polyunsaturated fats tend to decrease blood cholesterol levels
In relation to this, chemists describe saturated fat as hard fat that is dense and uniform. Their molecular linkages hold the carbon atoms together, hence they tend to be solid at room temperature.
Contrary to this are the properties of polyunsaturated fats from vegetable oils where the molecular structure spaces are reactive and open, hence they remain liquid even when kept inside the refrigerator.
Polyunsaturated Fatty Acid (PUFA)
PUFA is unsaturated oil with many spaces and color as clear as water but with varying degrees of saturation. Example of which is the sunflower oil that is more fluid when it is more unsaturated.
Some Polyunsaturated Fatty Acid (PUFA) can lower blood pressure due to its linoleic acid content, a raw material of prostaglandin 2 (PG2) that helps in the contraction and relaxation of muscles. PUFA also reduces the blood pressure by decreasing the blood viscosity. Decreased blood viscosity means lower total peripheral resistance and lower blood pressure.
This is how it differs to saturated fats, which increase blood viscosity resulting to high blood pressure.
The emphasis here is the consumption of unsaturated fat like PUFA to provide the important function of fats in our body yet still maintain our blood cholesterol at a low level. Also, a special component of PUFA, called omega-3 oils are found in certain fish such as salmon, tuna, mackerel, lake trout, albacore tuna, etc, and other vegetables.
In view of this, a natural way of reducing blood cholesterol level to help normalize our blood pressure is to shift our diets from meat and butter to fish, vegetables and vegetable oils with PUFA.
However, Omega-3 oils should not be taken if there is allergy to fish or soybeans. Take only what is recommended by the doctor because an overdose has possible side effects like fever, chest pain, uneven heartbeats, back pain, unpleasant taste in mouth, belching or mild skin rash.
Further, this can affect the effectiveness of estrogen, blood thinner, beta- blocker, and diuretic drugs. In order to reap the best results from omega-3 oil, this should be taken in with food.
Several clinical studies have proven that eating a low-fat diet and polyunsaturated fat (PUFA) have significant effects in normalizing the blood pressure and cholesterol levels thereby reducing the risk for heart disease.
