1) Grape seed oil contains procyanidins, flavonoid and vitamin
E which are antioxidants. Different studies resulted differently
to the effect of Vitamin E. A double-blind study at Vitamin E, researchers
found that supplements lowered the risk for coronary artery disease.
1) Grape seed oil also contains linolenic acid. Linoleic
acid in grape seed converted by intestinal bacteria to Conjugated
linolenic acid (CLA) after taken. CLA prevents tumor growth.
2) Linoleic acid can replace other fats in the diets to cause
HDL (good Cholesterol) levels to rise and LDL (bad cholesterol)
levels to fall, actions consistent with the prevention of heart
disease.
3) Antioxidant supplementation may help Alzheimer's disease
since "oxidative stress" may play a role in this dementia
trouble
Concerns
Chemically, there are several different
types of Vitamin E. The one found naturally in our foods is gamma-tocopherol,
a potent antioxidant. On the other hand, the Vitamin E found in
grape seed, is mostly alpha-tocopherol. There is laboratory evidence
that when taken in very larger amounts, alpha-tocopherol can block
the effects of gamma-tocopherol.
Precautions
Patients with high blood pressure, diabetes,
or bleeding tendency (disease or under anticoagulant treatment) should
be careful for the dose of grape seed to be taken. Consult to your
physician is a must. Very high doses of Vitamin E can be dangerous.
Dosage
The Effective dosage has never really
been determined. Most researchers feel that if Vitamin E supplements
are to be taken, then at least 800 International Units a day will
be required to produce any benefit. But many believe the suitable
dose for migraine, painful menstruation, and osteoarthritis is less
than 100 IU. For chronic fatigue syndrome, PMS, menopause and varicose
veins take up to 400 IU a day, no longer than one month.
Summary
There is evidence that linoleic acid supplementation
causes HDL (good cholesterol) to increase and LDL (bad cholesterol)
to decrease. This could prevent coronary heart disease. Vitamin
E supplementation, whether from grapeseed or from some other source,
helps prevent prostate cancer. Taking a consideration of the possible
benefits and the lack of significant toxicity, grape seed is a good
dietary supplement.
Interesting Facts
The discovery of the fact that fruit
seeds can be use to prevent or treating disease is much recent.
All because the containing of the seeds provided an antioxidant
effects. Gape wine more effective than juice because of the presence
of the substance from seeds.
