Black foods have magical nutrient effects that are resistant to oxidation, slow ageing, increased immunity and cancer resistance. In addition, black food contains calcium, iron, selenium, zinc, etc., which is essential for many humans, and contains higher proteins, fats and unsaturated fat acids relative to those of other colours. Unsaturated fatty acids have a significant effect on reducing blood viscosity and the levels of cholesterol and triester in blood, so we usually eat black sesame paste, which is very good for the body。
