The New Generation of Superfoods
Harnessing the Power of Food to Boost Health and Immunity.
Aug 31, 2008
Ultra-nutritious superfoods are increasingly being touted as the answer to a number of health matters, with claims ranging from improving IQ, to preventing cancer and heart disease, increasing sporting ability and enhancing appearance. Although the benefits are often overstated there’s little doubt that they are a worthwhile addition to any diet, but is the marketing hype surrounding superfoods just that - hype used to repackage foods that people already know to be good for them?
There's no official definition and no definitive list of superfoods. They are generally foods which are all rich in nutrients, vitamins, minerals or other powerful plant chemicals, which are also often low in calories. Some of the best known are listed below with their well-publicised health claims:
Salmon - fewer calories than red meat and a great source of protein and Omega 3 oils. Omega 3 can help keep joints healthy and help to maintain a healthy heart.
Broccoli - as one of the richest sources of antioxidants, broccoli boosts the immune system and it contains Vitamin C which helps the body absorb iron.
Blueberries - they are one of the best sources of the antioxidant, Anthocyanin, which may contribute to a healthy blood circulation, keeping the heart healthy and helping maintain youthful, healthy skin. They contain Vitamin C and have powerful antioxidants which help strengthen the immune system.
Beans - high in fibre, low in calories and great for maintaining the heart and digestive health.
Turkey - extremely low in fat and calories, and a great source of protein and B vitamins, which help to support an energetic lifestyle.
Oranges - contain Vitamin C which helps to boost the immune system and helps to support growth and development in children.
Pumpkin - high in potassium which may help control blood pressure and also high in Beta Carotene and Vitamin C, which boosts the immune system.
Tomatoes - a very good source of Vitamin C and they also contain Beta Carotene, which is converted into Vitamin A in the body and Lycopene, a great antioxidant.
Oats - may lower cholesterol, maintain heart health and are high in fibre and protein.
Spinach - rich in Vitamin C, Calcium and Beta Carotene. It helps to strengthen the immune system, increase levels of folic acid and keep blood and bones healthy.
Soy - foods like Soy milk and Tofu may help reduce cholesterol as they are a good source of Soya protein, which is great for vegetarians. They are also sources of antioxidants and Omega 3 oils, helping to strengthen the immune systems and maintain a healthy heart.
Tea - full of antioxidants which help to protect the immune system.
Yoghurt – a great source of Calcium and other beneficial nutrients. Live cultured yoghurt also contains live bacteria called Probiotics which may be associated with health benefits, such as improving the balance in the digestive system.
Walnut – a nutritional powerhouse filled with fibre and high polyunsaturated fat which may help to lower cholesterol.
Harnessing the power of Superfoods
Despite the much-hyped properties of these foods, they shouldn’t be regarded as medicinal substitutes, but more as part of a balanced diet. Up to one third of cancers and a high proportion of heart disease are thought to be associated with diet, and modifying the food people eat is one of the best defences against them.
Superfoods provide extra amounts of vitamins, minerals and fatty acids essential to growth and to repair of DNA damage in the cells. By incorporating as many as possible into a daily diet, people can reap the health benefits and enjoy a balanced and varied diet.
