Importance of Food
Food is something that provides nutrients. Nutrients are substances that provide: energy for activity, growth, and all functions of the body such as breathing, digesting food, and keeping warm; materials for the growth and repair of the body, and for keeping the immune system healthy.
Food is usually of plant or animal origin and contains essential nutrients, such as carbohydrates, fats, proteins, vitamins, or minerals. The substance is ingested by an organism and assimilated by the organism’s cells to provide energy, maintain life, or stimulate growth
1. Good nutrition improves well-being:
Eating a poor diet reduces physical and mental health because eating healthy allows people to be more active. Two-thirds of people who eat fresh fruit and vegetables daily report no mental health issues, as reported by the Mental Health Foundation. Compare this to those who do have some level of mental health problems and have generally reported eating less healthy foods and more unhealthy foods. Feelings of well-being can be protected by ensuring that our diet is full of essential fats, complex carbohydrates, vitamins and minerals.
2. Maintains your immune system:
Our immune system is our defence against disease, but poor nutrition is the most common cause of immunodeficiency worldwide. Maintaining your immune system requires an intake of proper vitamins and minerals. Eating a well-balanced diet, including fruits, vegetables and food low in fats, will help support a healthy immune system.
3. Delays the effects of ageing:
Foods like tomatoes, berries, avocados, nuts and fish all contain certain vitamins and minerals that are good for the skin. For example, tomatoes contain vitamin C, which helps build collagen, in turn making your skin look firmer and slow premature ageing. Berries are full of antioxidants and vitamins and eating them promotes cell regeneration for new skin.
4. Gives you energy:
Our bodies derive energy from the foods and liquids we consume. The main nutrients our body uses for energy are carbohydrates, fats and protein. Carbohydrates such as whole-grain bread and starchy vegetables are the best for prolonged energy since they are digested at a slower rate. Water is necessary for the transport of nutrients, and dehydration can cause a lack of energy. A deficiency in iron may cause fatigue, irritability and low energy. Food rich in iron includes seafood, poultry, peas and dark green leafy vegetables such as spinach.
5. Healthy eating positively affects your mood:
Diets low in carbohydrates increase feelings of tension whereas diets high in carbohydrates have a more uplifting effect on mood. A diet rich in protein, moderate in carbohydrates and low in fat will have a positive effect on mood because it leaves an adequate supply of iron, omega-3 fatty acids and iron. As much as food affects our mood, mood affects our food choices. When we experience feelings of sadness, we are more likely to choose unhealthy foods. People feeling happier feelings are more likely to choose.
6. Increases focus:
Food has an impact on the way we think. When the body is low on glucose, the brain is not receiving the energy it needs to remain focused. Eating fruits and vegetables throughout the day helps keep the mind healthy and engaged.
7. Healthy diets may lengthen your life:
Your body needs food in order to survive, but the process of breaking down food nutrients, or metabolizing, causes stress on the body. Overeating creates more stress on the body and could lead to a shorter lifespan. According to research done by Columbia University, 18 percent of deaths among white and black Americans can be attributed to obesity.
