Nutritional highlights Tofu is a good source of protein and contains all eight essential amino acids. It is also an excellent source of iron and calcium and the minerals manganese, selenium and phosphorous. In addition, tofu is a good source of magnesium, copper, zinc and vitamin B1. Tofu is an excellent food from a nutritional and health perspective. It is thought to provide the same sort of protection against cancer and heart disease as soya beans. A 100g serving contains: 70 kcal 3.5g fat 1.5g carbohydrate 8.2g protein 0.9g fibre Research Soya protein (from which tofu is derived) is believed to help lower levels of bad cholesterol (LDL). Tofu contains phytoestrogens called isoflavones – a group of chemicals found in plant foods. They have a similar structure to the female hormone oestrogen and therefore mimic the action of oestrogen produced by the body. They naturally bind to oestrogen receptor sites in human cells including breast cells – potentially reducing the risk of breast cancer. Due to the phytoestrogen content of soya, many women decide to include soya rich foods like tofu in their diet as they enter the menopause. During the menopause, the body’s natural production of oestrogen stops and symptoms may arise. As phytoestrogens act as a weak oestrogen, they may help relieve symptoms by boosting levels slightly, reducing hot flushes in some women. Genetics and environmental factors play a huge part in how our bodies react to certain foods, so as yet we can’t say whether a diet rich in phytoestrogenic foods is beneficial or not. If you are a vegetarian or vegan, soya based foods like tofu can be an invaluable part of your diet.
