Many individuals choose to limit what foods they eat for
reasons of health, morality, or other factors. Additionally, many people choose
to forgo food from animal sources to varying degrees; see vegetarianism,
veganism, fruitarianism, living foods diet, and raw foodism.
The nutrient content of diets in industrialised countries contain more animal
fat, sugar, energy, alcohol and less dietary fiber, carbohydrates and
antioxidants. Contemporary changes to work, family and exercise patterns,
together with concerns about the effect of nutrition and overeating on human
health and mortality are all having an effect on traditional eating habits.
Physicians and alternative medicine practitioners may recommend changes to diet
as part of their recommendations for treatment.[2]
More recently, dietary habits have been influenced by the concerns that some
people have about possible impacts on health or the environment from genetically
modified food.[3] Further concerns about the impact of industrial farming on
animal welfare, human health and the environment are also having an effect on
contemporary human dietary habits. This has led to the emergence of a
counterculture with a preference for organic and local food.[4]
