How to Choose the Right Food
Food is any material consumed to supply nutrition to an organism for life. Food is generally of animal, plant or fungus origin, and consists of essential nutrients, including proteins, carbohydrates, vitamins, or iron. The composition of food is varied throughout the world, with the diet of a typical individual highly varied from another in certain countries but similar in others. Although humans have been eating food for thousands of years, much of what they eat today has become modern commercial food, which is subject to intensive marketing and consumption.
A food group represents the main groups of food that humans consume. These groups include vegetables, fruits, whole grains, dairy products, meat, fish and poultry. Each of these food groups is normally broken down into smaller sub-groups, with each sub-group having differing levels of importance to the human body and consequently having varying calories. It is important to consider the number of calories in the different food groups and compare these with the average number of calories per day for your daily consumption, as the number of calories consumed may be more or less than the recommended daily allowance.
Humans are animals living in a complex world. To survive, all these animals need to eat food that provides the energy they require to live. Since their very beginnings, humans have been trying to feed themselves using a variety of methods, some of which are more successful than others, while other food sources have become extinct. Today, the majority of people’s diet consists of processed, packaged, frozen and chemically treated foods that provide less nutrition and more calories than they need to survive.
Because of this, many people around the world struggle to keep their weight under control, as they have no idea on how to eat enough food to maintain their weight, no matter what kind of lifestyle they lead. As a result, people become overweight and become more susceptible to many diseases, such as high blood pressure, diabetes, heart disease, stroke and cancer. They also suffer from digestive disorders and nutritional deficiencies, such as insufficient proteins and iron, making it difficult for them to process and absorb the proper nutrients. In addition, many people who buy food in stores do not pay enough attention to the ingredients and nutritional information of the food itself, leading to nutritional deficiencies and illnesses.
Fruits and vegetables are the most nutritious food groups in the world, providing more antioxidants, vitamins and fiber than any other food group. In addition, when properly digested and used, dietary fiber helps lower cholesterol and blood pressure, while simultaneously strengthening the immune system and controlling hunger. When it comes to controlling hunger, fruits and vegetables are better alternatives to processed food because of their natural appetite suppressants, fiber molecules that are both insoluble and polysaccharides. The best way to eat fruits and vegetables is raw, unprocessed, preferably boiled, in their natural juices.
Aside from fruits and vegetables, oil is considered to be a very good food because it can easily dissolve into the bloodstream without producing any change in one’s blood sugar. When oils are applied or consumed in excess, they produce fatty acids which can raise the level of cholesterol in the body, as well as increase the level of triglycerides (fatty substances) in the blood. Therefore, oils should be limited to a certain amount of intake per day to maintain a healthy blood lipid profile. The two most popular types of fat are monounsaturated and polyunsaturated fat; oleic acid is the latter, which is found mostly in nuts and olives.
