Food is a combination of various ingredients that are consumed for nutrition. It contains essential nutrients like carbohydrates, proteins, fats and vitamins which are required for our well-being.
Having healthy eating habits is very important as it has a direct effect on our health and life span. Eating nutrient-dense foods like fruits, vegetables, whole grains, lean meats, nuts and seeds help reduce your risk of disease.
1. It Provides Nutrients
The body uses nutrients to grow, repair, and regulate its functions. A healthy diet consists of a variety of foods that provide different classes of nutrients. These include carbohydrates, proteins, fats, and minerals. Each nutrient has its own unique function and purpose in the body.
For example, sugars provide energy in the form of glucose. Vegetables, fruits, and whole grains contain vitamins and minerals. Legumes and beans provide protein. Oils and fatty acids supply the body with fats, which help maintain proper cell structure.
In developed countries, most people have access to a wide variety of nutritious foods. However, many still suffer from malnutrition. This is mainly because they lack the money or the land to buy healthy food. In addition, their diets are too high in salt, sugar, and unhealthy fats.
2. It Gives Energy
Food provides a mixture of chemicals that enable our bodies to build and repair organs, regulate body temperature, think and move around. This energy is provided by carbohydrates, proteins, fats, vitamins and minerals.
The energy from sugars and fats is released in cells as packets of chemical energy called ATP. Each cell uses this energy to function.
Food can give us instant energy, but it’s best to get our energy through balanced meals that contain low glycemic foods such as whole grains and vegetables. It’s also a good idea to include protein and healthy fats in your meals, as these foods provide sustained energy. For example, a yogurt with fresh berries and a drizzle of local honey or maple syrup will keep you fueled for hours.
3. It Helps in Weight Loss
Food is important for our life because it gives us energy to carry out activities and provides the nutrients we need to survive. It can come from animals or plants and is usually enjoyable to eat. It contains protein, fat, carbohydrates, vitamins, minerals, and water. It also helps our body burn calories to produce energy.
Food is also important for our mental health and well-being. Studies have shown that people who eat healthily are happier and more satisfied with their lives than those who do not. This is because healthy foods can help control our weight, reduce risk of chronic diseases, and improve mood and sense of well-being. Some examples of healthy foods include fruits, vegetables, whole grains, low-sodium soup, nuts and seeds, olive oil, balsamic vinegar, and garlic.
4. It Helps in Deficiency
Food is an essential substance used for correct nutrition of living beings and sustaining their physiological and metabolic functions. It is also responsible for regenerating tissues, increasing growth and vitality, and regulating body temperature. It also has a psychological impact, encouraging communication and social ties among people.
Eating a healthy diet throughout the life span can prevent malnutrition and other chronic diseases such as heart disease, type 2 diabetes and certain cancers. However, many people struggle to eat enough fruits, vegetables and whole grains.
In some countries, war or political instability make it difficult to grow or buy adequate food. During these times, millions of people become dependent on international food aid.
5. It Helps in Deficiency Conditions
Getting enough of the right foods is essential for good health. Food provides the nutrients that are important for the body, including carbohydrates, proteins, fats, water, and minerals. Poor diet and malnutrition are a leading cause of death worldwide.
In developed countries, people have access to a variety of healthy foods. However, the cost of nutritious foods can be prohibitive for some people. Poorer communities tend to have less access to fresh, affordable foods and may have higher risk of malnutrition. Children and older adults may also have specific nutritional needs.
Throughout history, food has been fortified with certain vitamins and minerals to prevent deficiency conditions. These include iron to reduce anemia, vitamin D for rickets, and iodine for goiter. Adding these nutrients to food makes them easier for people to eat and absorb.
