Sources of Food


global food production is maintained by agricultural practice, horticulture, animal husbandry, and pisciculture. According to United Nations, if food production isn’t increased by another 50% by 2050, there will be a severe crisis. It’ll lead to massive loss of lives due to malnutrition. So, there have to be new non-conventional sources of food in the form of microbial protein and seaweed, which will at least partially combat this food crisis.

Sources of Food:

1. Agricultural Crop: These crops include rice, wheat, millet, maize, and other food grains.

2. Vegetables: This includes potatoes and other leafy vegetables that are a possible source of starch, minerals, vitamins, and roughage.

3. Fruit Plants: These plantation crops are sources of sugar, organic acids, and vitamins.

4. Animal Husbandry: Rearing of cattle for milk, flesh mainly acting as the major source of protein.

5. Pisciculture: It mainly includes major and minor carp through induced breeding and composite culture. Fishes are potent sources of protein and essential fatty acids.

6. Non-conventional Food: The agricultural land being constant, the world is now keener to develop non–conventional food resources which include the single cell protein like that obtained from yeasts and Spirulina. The development of seafood in the form of different marine macrophytic algae and sea shells.
