Although it has been part of the diet in China and the Far East for thousands of years, soya protein is something of a mystery to many people in the West. It may have a slightly cranky, health-food image, soya is actually a tasty alternative to meat or dairy products. It is also great for people who are trying to look after their hearts.

Soya beans are the fruit of the soya plant and although we often only see them when they have been turned into something else, the beans themselves look like small white peas when dried. But these little white beans are incredibly versatile and can be turned into anything from milk and tofu to sausages and even dairy-free chocolate.

Soya protein provides a low-fat alternative to animal protein and has been shown to help lower the bad' cholesterol, LDL. It is also high in fibre which can help to carry these bad fats away in the bloodstream.

Having said that, soya is generally regarded to be most beneficial when eaten as part of a healthy, balanced diet. The British Heart Foundation says that it is not recommended that people rely on soya products alone in order to lower their cholesterol.

As well as being packed with vitamins and minerals, soya protein contains all the essential amino acids, which makes it superior to most plant proteins. Soya bean products also contain the anti-cancer substance phytoestrogen, which is thought to help balance male and female hormones.

Processed soya beans are turned into everything from milk to meat substitutes, but in their natural undried state they can be eaten as a vegetable, cooked whole in their pods.

Known as edamame, these nutrient packed edible pods taste like a cross between peas and broad beans and are delicious when eaten cold in salads or steamed and salted, Japanese style, and served as a healthy snack.

Experts recommend that a daily intake of 17g to 25g of soya protein is best for optimal heart health benefits. Tofu, tempeh, soya milk and yoghurts are a great source of soya protein and you can even buy soya flour for use in home baking. There are many soya-based products on the market including: u Soya mince - a great tasting cheap alternative to beef mince.

u Meat free sausages and burgers - a healthy alternative for the high fat meat versions.

u Soya fillets -- use in casseroles with your favourite sauces.

u Soya milk - makes delicious porridge, for a heart healthy breakfast.

Eating a healthy balanced diet, low in saturated fat is the best way to look after your heart. So try replacing some of the meat products you eat with soya and enjoy a low-fat healthy heart diet.
