Health The most well-known health benefit of blackcurrants is that they contain large amounts of Vitamin C. Vitamins are substances we need to enable our bodies to live, grow and reproduce normally. Vitamin C is an essential nutrient - it cannot be made by the human body and we must therefore eat foods which contain it (Bibliography Ref: 13). Because the body breaks down Vitamin C very quickly and does not store very much, we need to eat Vitamin C containing foods regularly, preferably every day.
We must consume a minimum amount of Vitamin C to prevent scurvy. The recommended daily allowance (RDA) for Vitamin C is 60 mg. This is well above the level required to prevent scurvy to ensure that our bodies stay healthy. However, apart from the world's poorest countries, diets in the 21st century are very unlikely to contain less than this minimum amount.
Vitamin C looks after body tissue health
Vitamin C is needed by the body to make collagen, an important structural material in bones, teeth, skin, ligaments (that connect bones to other bones in joints), tendons (that connect muscles to bones) and cartilage (that helps to provide cushioning in joints).
Collagen is responsible for skin elasticity and its degradation leads to wrinkles. Adequate Vitamin C is therefore necessary to maintain the health of all of these body tissues and deficiency can result in tooth loss, joint pains and problems with bone and connective tissue (Bibliography Ref: 14, 15).
Vitamin C helps iron absorption
Vitamin C helps the body absorb and use the iron we get from vegetables and cereals (Bibliography Ref: 16, 17, 18, 19). Iron is an important mineral because it enables blood to carry oxygen to all our bodily tissues. People who don't get enough iron from their food become anaemic.
Vitamin C boosts the immune system
Scientific studies have shown that Vitamin C can boost many different parts of the immune system (Bibliography Ref: 20,...
