- Nutrient-rich foods and their health benefits
Superfoods
Superfoods contain all or nearly all the vitamins, minerals and trace minerals the body needs
* Examples include algae, sprouts and bee pollen
* The term superfood is used more and more liberally in the food industry today
* Remember, a true superfood contains a wide range of nutrients
* Superfoods incorporated into a whole food diet are key to supporting human health, and are a highly therapeutic addition to one’s diet
Superfoods: oxygen radical absorbance capacity (ORAC)
Superfoods contribute towards good health with their excellent nutrient profile. This profile includes a rich abundance of antioxidants, which helps them to support healthy ageing.
* Antioxidant capacity of a food is often referred to by highlighting its oxygen radical absorbance capacity (ORAC) score. This is a laboratory tests that aims to quantify the total antioxidant capacity (TAC) of a food.
* Superfoods are rich in vitamins and minerals, and generally contain phytonutrients, enzymes, essential fatty acids and antioxidants
Phytonutrients = plant nutrients
Superfoods or superpowers
Super foods do not have superpowers! They work in tandem with the healthy diet– Enhancing it.
* No amount of wheatgrass will make up for a sedimentary lifestyle and a diet based on highly processed foods
* Local, seasonal produce, ideally organic, is preferable to exotic imports of super foods, which can be expensive, and don’t necessarily have a higher nutritional value, whilst adding to the carbon footprint e.g. goji berries are high in vitamin C but imported from China. Red– and blackcurrants are an excellent source of vitamins C and readily available in the UK in Europe
Nutrient rich foods
Nutrient rich foods are high in nutrients and often low in calories, and true super foods contain all or nearly all vitamins, minerals and trace minerals the body needs.
- Nutrients rich foods and super foods are therapeutic and should be a key feature of one’s diet
- They provide an abundant source of macronutrients, micronutrients, fibre, enzymes (when not processed or cooked) and phytonutrients
