Basic Food Requirements of the Human Body?

What are the basic food requirements of the human body?

As humans, we require a variety of nutrients to maintain our health and well-being. Food is the primary source of these nutrients that our bodies require to function optimally. Basic food requirements of the human body include carbohydrates, proteins, fats, vitamins, minerals, and water. In this article, we'll delve into each of these nutrients, their importance, and the way our bodies utilize them.

1. Carbohydrates:

Carbohydrates are an essential macronutrient and serve as the main source of energy for our bodies. Our body breaks down the carbohydrates we eat, like sugars and starches, into glucose or blood sugar - our primary source of energy. Carbohydrates are found in different forms, and we can choose between complex and simple sugars. Simple sugars, such as those found in candies, are broken down quickly and absorbed rapidly and can lead to spikes and crashes in our blood sugar levels. On the other hand, complex carbohydrates, such as those found in whole grains, beans, fruits, and vegetables, take longer to digest and provide a steady supply of energy. Experts recommend that we get between 45% and 65% of our daily calories from carbohydrates, emphasizing the importance of choosing healthy sources.

2. Proteins:

Next on our list of basic food requirements are proteins, which make up essential components of our bodies like tissues, organs, and muscles. We rely on proteins for the building, maintenance, and repair of body tissues that wear out daily. Our bodies break down the proteins we eat into amino acids - the building blocks of proteins. There is a range of sources from which we can get proteins like nuts, seeds, meat, fish, poultry, and dairy products. Amino acids also play other essential roles in our bodies such as immunity, enzyme and hormone production, and gene expression. It is recommended that we consume about 10-30% of our daily calories from protein.

3. Fats:

Fats are another essential macronutrient that is crucial for our bodies to function adequately. Fats help us absorb nutrients, produce hormones and keep our organs insulated. Although we have a tendency to associate fats with unhealthy foods, including overly processed snacks and fast foods, our bodies underlyingly need them to work effectively. There are different types of fats, including saturated and unsaturated fats. We're advised to limit our intake of saturated fats, as they're linked to an increased risk of heart disease. In contrast, unsaturated fats help maintain healthy cholesterol levels and should form the bulk of our daily fat intake. Sources of unsaturated fats include nuts, seeds, avocados, and most vegetable-based oils.

4. Vitamins and Minerals:

Vitamins and minerals are the micronutrients our bodies require in smaller amounts to function at their optimum level. Several vitamins and minerals perform various body functions when absorbed into our bodies. For instance, Vitamin C is responsible for the production of collagen - a protein that helps to maintain healthy skin, cartilage, bones, and blood vessels. Minerals like calcium aid in building strong bones and teeth, while the iron is necessary for the production of hemoglobin in red blood cells. Examples of where we can get these micronutrients are whole fruits and vegetables, nuts, legumes, whole grains, dairy products, meats, seeds, and others.

5. Water:

Last but not least on our list of basic food requirements is water. Although it isn’t a nutrient, water is a vital component of our body and helps us preserve normal body temperature, transport essential nutrients, remove waste and toxins from our bodies, and maintain the proper functioning of our organs. Doctors recommend drinking 8-10 glasses of water per day for the average adult.

Conclusion:

In conclusion, meeting the basic food requirements of the human body is crucial, as it helps us function at our best by providing us with the nutrients our bodies need. Carbohydrates are an essential source of energy, while proteins are responsible for building and repairing our body tissues. Fats are crucial for healthy body functions and maintaining healthy cholesterol levels. Finally, micronutrients such as vitamins and minerals play various vital roles, including building strong bones and teeth or production of hemoglobin in our bodies, among other functions. We should always aim at eating a balanced diet to ensure our bodies receive all the necessary nutrients to function optimally.
