Dietary recommendations

There are a number of diets and recommendations by numerous medical and governmental institutions that are designed to promote certain aspects of health.
[edit]World Health Organization
The World Health Organization (WHO) makes the following 5 recommendations with respect to both populations and individuals:[2]
Achieve an energy balance and a healthy weight
Limit energy intake from total fats and shift fat consumption away from saturated fats to unsaturated fats and towards the elimination of trans-fatty acids
Increase consumption of fruits and vegetables, legumes, whole grains and nuts
Limit the intake of simple sugars
Limit salt / sodium consumption from all sources and ensure that salt is iodized
Other recommendations include:
Sufficient essential amino acids ("complete protein") to provide cellular replenishment and transport proteins. 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. Fruits such as avocado and pumpkin seeds also have all the essential amino acids.[3][4]
Essential micronutrients such as vitamins and certain minerals.
Avoiding directly poisonous (e.g. heavy metals) and carcinogenic (e.g. benzene) substances;
Avoiding foods contaminated by human pathogens (e.g. E. coli, tapeworm eggs).
