Food is any material eaten to supply nutrition to an organism. Food is generally of animal, plant or fungus origin, and generally contains necessary nutrients, including vitamins, proteins, carbohydrates, and fats. Plants obtain their food from the soil in which they grow; animals, sea foods, fruits, vegetables, seeds, nuts, mushrooms, grains, and other grains are prime sources of food. Fungi are also a significant source of food, particularly yeast, spores, and aphids.
Oils are considered food components that provide both essential fatty acids and non-essential fatty acids and are used by most people for general purpose. Essential fatty acids are called omega-3 fatty acids, and they are vital to human health. Non-essential fatty acids are called omega-6 fatty acids. Both of these types of fats are important for obtaining the required amounts of vitamins, minerals, and other nutrients.
The proper intake of food is essential to achieving and maintaining a healthy diet and is required for overall health. A variety of food is beneficial in ensuring optimal nutrition security. Meals that consist of whole grains, dairy products, lean meats, fruits, vegetables, legumes, whole grain breads, and cereals are good dietary choices. A variety of foods from all food groups, but particularly those rich in calories, are good dietary choices to maintain healthy eating.
