The word “food” can have two completely different meanings. For many people, food is simply something that tastes good. For other people, food is the substance out of which a person gets sustenance. More broadly speaking, food is any material eaten to give the body necessary nutrition. Food is generally of animal, plant or fungi origin, and has the necessary nutrients, including vitamins, fats, carbohydrates, proteins, or minerals, which the body needs in order to perform its functions.
There are two broad categories under which food is classified: organic and inorganic. Foods are inorganic if they are produced by means of inorganic processes, that is, if the substances put into them were not made by living things. Foods that fall under this category include all processed sugars, including table sugar; all meat products (meat, fish, milk, etc. ), and all foods that are derived from plant materials (all grains, breads, etc. ).
Organic food is much more desirable than inorganic food, because it consists of living organisms, such as plants and fungi, as well as all the different foods we eat that are organic. Organic food is not only good for you; it is also good for the environment. Therefore, if you want to make sure that you and your family get all the nutrients necessary to lead healthy lives, then you need to start eating organic foods as soon as possible.
Animal origin foods tend to be somewhat easier to digest than those that are from plants, as the animals feed on the plants that they consume. However, there are a lot of differences between animal source foods and plant based foods. First, animal-origin foods tend to contain considerably more protein, fat, carbohydrates, vitamins and minerals than do plant source foods. This makes animal source foods particularly valuable when you are trying to gain weight or lose weight because of the higher amount of essential nutrients that they provide. Also, animal-origin foods generally have far higher quantities of some essential nutrients than do plant-based foods.
A good example of an animal food is steak. Steaks are packed with calories, especially if they are cooked properly, but steaks are also extremely rich in several kinds of minerals. Although the mineral content of steaks varies, one of the minerals found in many varieties of steak is calcium. Calcium is needed by the human body, because it is an important vitamin that helps with bone growth and development, among other things. So you can see that there is a definite link between nutrition and a diet rich in calcium.
The above examples of food types are just a few of the foods that are important for nutrition. There are many other foods, some of which we have never heard of, such as sweet potatoes and avocado. Eating a healthy diet is not only healthy for your body, but is also very easy to do when you know what kind of foods you like. The best thing about nutrition, as shown above, is that you don’t need to spend a lot of time learning about nutrition – in fact, learning about nutrition is really simple.
