Food is any material consumed in order to provide nutrition to an organisms. Food is generally of animal, plant or fungi origin, and normally contains necessary nutrients, including protein, fats, carbohydrates, vitamins, or other minerals. In humans, food is categorized into three main groups: food, drink and fat. Each of these groups has its own purpose, while food provides basic nourishment to the body; drink is the material that acts as a solvent in digesting food, and fat is that which gives the body heat. The three categories of food are not mutually exclusive, but each group has more of the required energy than the other.
When it comes to food, we can categorize it into three sections: the living foods, which are all plants and animals; the living drinks, which are watery beverages, and the digestible proteins or carbohydrates. Plants and animals contain almost the identical amount of all the nutrients, but certain substances are necessary for their existence. For instance, plant food cannot exist without carbohydrates, as the only source of energy.
We can derive the calories from plant food by using the carbon compounds in them, and so convert it into food. A good example of a living food is sweet potatoes. Just like all other plant food, sweet potatoes have some substances, such as starch and protein, that are necessary for their existence. Sweet potatoes also contain lots of the important nutrients, such as vitamins A and B, which are very useful in providing energy to the body.
However, not many people consider eating sweet potatoes or any other kind of vegetable or fruit raw, unless they are prepared as delicious foods. This is why it is very important to buy food in stores, and make sure you always have enough food in your home. Today, there is much food processing done to prepare food products, especially ready-made food stuffs. There are many people who do not believe that they can find ready-made food, but this should not be an excuse for not knowing how to cook food properly.
In case you are used to eating white meat, for instance hamburgers or steak, you might be surprised to learn that these kinds of meat are usually cooked in fatty oils that are usually not healthy for you. Instead of eating white meat, you can start eating lean meat such as turkey or chicken. Fish is also another healthy food that you can start eating. Fish contains omega-3 fatty acids, which are good for your health. There are many people who love fish because they feel that fish can satisfy the taste buds of their palate, which is not really true because there are different types of fishes, and some are more appetizing than others.
Eating fresh food is better than eating animal products. It will give you more energy, keep you away from obesity, promote a healthy heart, and help you lead a long and healthy life. Avoid eating fast food on a regular basis, especially if you are fond of burgers, hotdogs and other animal products. Learn how to cook new food and introduce it gradually so that you can become accustomed to it sooner. If you love eating meat, cook your own food, because cooking your own food gives you much satisfaction than eating meat bought from a carton.
