Surgery is minimally invasive and takes roughly 20-30 minutes. The pterygium is first carefully peeled, then a tissue graft is harvested from beneath your upper eyelid and placed over the removal site to reduce the chance of recurrence. The graft is usually secured with tissue glue and rarely needs sutures.
Proponents of functional foods say they promote optimal health and help reduce the risk of disease. A familiar example of a functional food is oatmeal because it contains soluble fiber that can help lower cholesterol levels. Some foods are modified to have health benefits.
More research needs to be done over these potential risks. GM crops also contributed to an increase in the number of functional foods or nutraceutical foods with added benefits. Nutraceutical is applied to isolated nutrients, dietary supplements and herbal products, specific diets, processed foods, and GM crops.
