Good Health

The word diet is often used to describe an eating plan intended to aid weight loss. However, diet really refers to the foods a person eats in the course of a day, or week. The more balanced and nutritious the diet, the healthier the person can expect to be. A balanced diet means eating the right amount of foods from all food groups.

A healthy diet is one that helps maintain or improve health. It is important for the prevention of many chronic disease such as: obesity, heart disease, diabetes, and cancer.[1]
A healthy diet involves consuming appropriate amounts all of the food groups, including an adequate amount of water. Nutrients can be obtained from many different foods, so there are a wide variety of healthy diets.
The World Health Organisation (WHO) makes the following 5 recommendations with respect to both populations and individuals:[2]
Other recommendations include:
  • Sufficient essential amino acids ("complete protein") All essential amino acids are present in animals. A select few plants (such as soy and hemp) give all the essential acids. A combination of other plants may also provide all essential amino acids (except rice and beans which have limitations).
  • Essential micronutrients such as vitamins and certain minerals.
  • Avoiding directly poisonous (e.g. heavy metals)
  • Avoiding foods contaminated by human pathogens (e.g. E. coli, tapeworm eggs).

Fruits and vegetables

The WHO recommends a minimum of 400g of fruit and vegetables per day. This groups excludes potatoes and other starchy tubers.[3] Fruits and vegetables also prevent several micronutrient deficiencies.[3]

Salt While a moderate amount of salt is required for health, a high salt diet can have detrimental effects on blood pressure[5].

An unhealthy diet is a major risk factor for a number of chronic diseases including: high blood pressure, diabetes, abnormal blood lipids, overweight/obesity, cardiovascular diseases, and cancer.[6]
