While most people choose a mainstream diet some people either cannot (due to a health condition or for religious reasons) or choose not to (for health or ethical reasons) eat certain types of food.
Food that is certified organic is free of any genetically modified components and free of pesticides and artificial fertilisers. Organic food is not necessarily any more nutritious than conventional food, but tends to be premium produce, which may be fresher and therefore retaining more nutrients. It is also free of the potential risks of eating traces of pesticides, or genetically modified foods. Organic food is, however, too expensive for many people to eat all the time.
Vegetarian diets can be adopted for moral reasons (i.e. animal welfare), ecological reasons (damage to the land by farming animals; unsustainable commercial fishing practices; more energy efficient to eat lower on the food chain), health reasons (diets lower on the food chain are typically lower in saturated fats and cumulative toxins) or religious reasons (certain castes in Hinduism, Sikh, many Taoists, Jains and many Seventh Day Adventists are vegetarian.) Vegetarians typically include dairy products and eggs in their diet (lacto-ovo vegetarians), while vegans eat no animal-derived food at all. Many vegetarians also exclude products like gelatine (found in jelly, lollies, and some firm dairy products) and cheese made with animal rennet. Semi- vegetarians may include fish in their diet, and some also include chicken.
This is the diet permitted under Islamic law. It excludes pork and any pig-based products, carnivorous animals, blood and intoxicants such as alcohol. Halal meat requires the animal to be killed according to Dhabiĥa.
This is the religious diet permitted in Judaism. Meat is restricted to animals which chew cud and have cloven hooves as well as birds, such as poultry. Meat must be killed according to shechita, which is similar to the halal requirements of Dhabiĥa. Meals cannot mix meat and milk.
