Malnutrition can affect everyone
We often only notice inadequate nutrition when a skirt suddenly becomes too loose or a belt no longer holds our trousers up properly. But tiredness, lethargy and stress can also be indications of deficiencies. Inadequate nutrition often happens gradually.
Any diet that does not cover our nutritional requirements bears the risk of poor nutrition. So even in the industrialised countries, inadequate nutrition and deficiencies of some nutrients are widespread.
