Facts and Food Sources of Stilbenoids

0

Stilbenoids are hydroxylated derivatives of stilbene with C6-C2-C6 structure. It belongs to phenylpropanoids family in biochemical terms and shares most of its biosynthesis pathway having chalcones. Stilbenoids could be formed by bacteria and plants. It is naturally formed by various plants when under attack by fungi or bacteria. It occurs naturally and is found in foods such as wine, blueberries and grapes. Its other sources include peanuts and cocoa powder.

Stilbenoids are phytoalexins which refers plant synthesizes compounds as a response to abiotic or microbial stress namely fungal infection and exposure to ultraviolet radiation. This activity of combating external stress is used by winemakers considering sun exposure and grey mold are common issues in food production. These protective chemicals make grapevine maintenance simpler. Moreover, stilbenoids are antioxidants.

There are two main stilbenoids such as pterostilbene and resveratrol. Study conducted in 1992 shows that resveratrol helps to inhibit growth of tumor in some animal models.

Dietary Sources

The food sources of Stilbenoids are blueberries, wines, grapes, cocoa powder and peanuts.

Health Benefits of Stilbenoids

Discussed below are some health benefits of Stilbenoids:

  1. Lowers inflammation

Inflammation is the natural response of body to injury, infection, stress or injury. It results redness, heat pain and swelling as the body deals with source of problem. Most of the positive inflammation shows the body is reacting to the threat and repairing damage. Yet, some inflammation is irrelevant and damages the body cells when there is no threat to counteract with. Study shows that stilbenoids are powerful anti-inflammatories which prevent unnecessary inflammation in the body. Further studies are required for confirmation.

  1. Anti-oxidant activity

Antioxidants are substances which maintain body’s cells safe from free radicals. Free radicals are harmful substances which release into body’s cells during oxygen based reactions. It is associated with diabetes, cancer, weak immune system and premature aging. Stilbenoids are powerful antioxidants which protects from unpleasant effects of free radicals.

  1. Eliminate toxins

Toxins are harmful substances which are formed within living organisms. Evidence shows that resveratrol may be antitoxic and protects from these natural poisons. Yet, further research is essential to confirm these effects.

As people ages, mental health suffers often. Stilbenoids is helpful for this problem. Study shows that pterostilbene helps to prevent mental deterioration while resveratrol helps to prevent Alzheimer’s disease.

Cancer is a health problem where deoxyribonucleic acid in body’s cells gets damaged and causes the cells to grow in rapid and out of control way which results formation of cancerous tumors. The cancerous cells spread to other areas of the body and damages the cells which surround it. Both resveratrol and pterostilbene helps to prevent this condition.

  1. Diabetes prevention

Diabetes is a health condition which forms when either body’s cells stop responding to insulin or pancreas deteriorate to form enough insulin. When left untreated, diabetes could damage body’s cells or vital organs. Luckily, stilbenoids helps to avoid this condition as evidence suggests that both resveratrol and pterostilbene prevents diabetes.

  1. Prevent heart problems

Heart disease is the leading reason for premature death in UK. Early research shows that stilbenoids helps to avoid this condition. Pterostilbene lowers the levels of LDL cholesterol or triglycerides while resveratrol prevents atherosclerosis and lowers LDL cholesterol levels.

  1. Prevent UV rays damage
