Food types on how to improve our health

Nearly everything we eat comes from plants, animals, birds, fish and other sea creatures like
shellfish. We can eat the edible parts of many plants like roots and leaves as well as things plants produce like fruits and seeds. We can also eat various parts of animals as well as things animals produce like milk. In many parts of the world people also eat insects and things they produce like honey .
Before the development of agriculture , people got food from the plants and animals in the world around them. They dug up roots, gathered fruits and seeds, hunted and trapped animals and birds and used spears and nets to catch fish. They also collected shellfish and other seafood as well as insects and bird eggs, and in many parts of the world people still do all these things.
Around ten thousand years ago agriculture began to develop when people in the Middle East, Asia and South America began cultivating plants and
domesticating animals and birds. They cultivated grasses that produced grains like rice and wheat, and grew plants that produced vegetables, nuts and beans . They also grew fruit trees and kept
poultry for meat and eggs and raised animals for meat and milk, and around eight thousand years ago people also began making dairy foods like cheese and yoghurt from sheep and goat milk.
As agriculture developed, farmers began producing more and more different types of food, and now we see a huge range of foods in supermarkets.
