Nutrition & health implications of palm oil in Indian diets.

ABSTRACT

To boost the edible oil production and attain self-sufficiency, one of the long-term strategies undertaken by the Indian government is promotion of palm oil production through oil palm cultivation. Compared to other traditional oils (except coconut oil) used in India, palm oil and palmolein have high saturated fatty acids and low linoleic acid levels. Studies conducted to evaluate the nutritional and health implications of substituting other oils with palmolein show that despite having low linoleic acid, the use of palm oil may not adversely affect the linoleic acid status of Indian population. Substitution of groundnut oil with palmolein in cereal based lactovegetarian diets providing about 30 per cent total fat calories, doubles the saturated fatty acids and reduces by half the linoleic acid content. The effects of this substitution in volunteers from the middle income group did not raise serum cholesterol and aggregability of platelets indicating that palm oil may not produce the deleterious effects associated with saturated fatty acids. The tocols present in palm oil are natural biological antioxidants and can therefore augment the antioxidant potential of Indian diets. Red palm oil is the richest natural source of carotenes which are powerful biological antioxidants. The major carotene in red palm oil is beta-carotene. Therefore, red palm oil can be used to prevent vitamin A deficiency which is widespread in India.
