Rice Bran: Occurrence, Chemical Nature and Medicinal Benefits

Occurrence:

• Rice bran is the nutrient-rich outer layer of rice grains that is removed during the milling process.

• It's a byproduct of rice milling but is increasingly recognized for its health benefits and is used in various food products and dietary supplements.

Here are the illustrations depicting rice bran and the detailed structure of rice grains.

Chemical Nature:

• Rice bran is packed with an array of nutrients, including dietary fiber, vitamin E (especially in the form of tocopherols and tocotrienols), ferulic acid, γ-oryzanol, and phytic acid.

• These components contribute to its antioxidant and anti-inflammatory properties.

Medicinal Benefits:

1. Antioxidant Effects:

• The high levels of vitamin E and other antioxidants in rice bran can help protect cells from oxidative stress and may reduce the risk of chronic diseases.

2. Cholesterol Reduction:

• Compounds like γ-oryzanol in rice bran have been shown to help lower cholesterol levels in the blood, contributing to heart health.

3. Anti-inflammatory:

• The nutrients in rice bran, including ferulic acid, have potential anti-inflammatory effects, which may help reduce the risk of various chronic conditions.
