What is food?
# Many livelihoods are tied to food
Many people make their living from food-related jobs. Agriculture plays a large role, although data shows it has declined over time. In 1991, 44% of the world’s population worked in agriculture. In 2018, the number had dropped to 28%. That’s still important, and agriculture isn’t the only area where food is involved. Supply chain work, food safety, food science and the restaurant industry are all about food.
The link between diet and climate is hard to overstate. Even if fewer people work in agriculture, all our food is produced that way. Scientists may be experimenting with lab-grown food, but we’re nowhere near producing enough to feed everyone. Climate change threatens food production. Some estimates suggest that global crop yields could fall by 30% by 2050. People already struggling with food insecurity would suffer the most.
Importance of food
After air and water, food is the third most important thing for living beings to provide energy and development, to sustain life or to stimulate growth. It’s one of the most complicated groups of chemicals. Food plays an important role in promoting health and preventing disease. In general, it consists of essential nutrients such as carbohydrates, proteins, fats, minerals and vitamins, which are consumed to support the nutrition of an organism and are ingested by an organism and assimilated by the cells of the organism to maintain health. These nutritious foods are grains, legumes, fruits, vegetables, oils, etc.
- Our body is like a machine; like an engine burning fuel, the body’s work due to the energy provided by food. The food we eat serves as fuel for energy production in the mitochondria. Glucose from food interacts with oxygen to form energy, carbon dioxide and water molecules. Our bodies use food intake to generate the driving forces to keep the lungs breathing, the heart beating and the limbs functioning.
- We go to the gym and do strenuous bodybuilding exercises, and we need protein for that. Therefore, fitness trainers advise us to consume these nutrients in order to consume a high-food diet. In addition, protein-rich foods such as legumes, milk, eggs, vitamin-rich vegetables and meat are recommended in order to build up enough muscles and get the perfect body.
- The feed contains proteins that provide amino acids for digestion. These amino acids build proteins and do a variety of jobs, from helping our metabolism to protecting our heart. The proteins are life-sustaining macronutrients that build body cells and other tissues to maintain form and function. Our bodies also use amino acids for energy when you are lacking in carbohydrates and fats.
- When we feel sick, we take food and medicine to be cured, we eat enough food, our immunity strengthens, and we feel relieved from cough, cold symptoms to a noticeable extent. Also, with most infections, illnesses or diseases, patients become very weak because they have stopped or are reluctant to eat.
- Malnutrition is a type of disease in which a lack of food or excess food causes the disorder. Lack of adequate nutrition along with administration of drugs leads to many problems such as drug accumulation, development of resistance to the drug by microbes, etc. This is because food is an enzyme inducer. As a result, drugs become more water-soluble in the metabolism and are excreted in the urine. Food gives the body the strength to safely absorb a drug and medication and also to metabolize it after its effect in the body. Many oil-soluble drugs are well absorbed in the presence of fatty foods.
- During a wound, fracture or inflammation, adequate nutrition will help overcome the pain and discomfort during the healing process. It points out that food is also used as medicine, without medicines cannot overcome some diseases such as tuberculosis, sunstroke, stomach ulcers, skin diseases, muscle pain, etc. So, one of the best techniques for overcoming illness is eating a sensible amount.
- Many people who are under stress and depression neglect to eat. But interestingly, eating the same food can relieve stress and tension. So when you are tense, ask him to eat enough and you will see him rid himself of stress and depression.
