The Importance of Proper Nutrition in Human Health

1. Introduction

Proper nutrition in human beings is a critical aspect in life. It essentially means “the process of providing or obtaining the food necessary for health and growth.” All people need to eat is a way of obtaining some of the necessary chemicals, especially glucose. Glucose is used to provide energy for the cells. The foods are transformed in the digestive system into glucose which is carried by the blood and transported to the cells of the body. There are good nutrition and bad nutrition. A healthy diet is food that helps in the growth of the human beings. A human needs to eat a variety and vegetables and plenty of water. All the human beings can get each and every nutrient from different kinds of foods. For instance, the Vitamin “C” is found in many foods such as strawberries, oranges, etc. So it is not essential to have the Vitamin “C” in every meal but everyone has to have some foods that provide the Vitamin “C”. On the other hand, bad nutrition is a diet that will cause your body to fail to operate properly. There are many causes of this such as too much sugar, not enough protein, even eating too much! Nowadays, a great many people in the world suffer from malnutrition especially in developing countries. Roughly, 60% of the world’s population is suffering from hunger and malnutrition. There are various forms of malnutrition, some of them are: Marasmus, Kwashiorkor, Obesity and Minerals Protein malnutrition. Modern living and modern diets can also lead to obesity, diabetes and other such illnesses. Such diseases were once found but occasionally and only in adults but nowadays children are also found to be affected by these diseases because of bad nutrition. On this occasion, there is a call for the World Health Organization to take serious action regarding this matter. In conclusion, we can say that it is important to have good nutrition. Good nutrition can help prevent disease and promote health. There are six categories of nutrients that the body needs to acquire from food: protein, carbohydrates, fat, fibers, vitamins, and minerals. By following the food pyramid, we can get all the nutrients from each kind of food. It is also important to have good hygiene. Hygiene involves preventing disease and promoting health by practicing cleanliness. For instance, washing hands before and after cooking, using preventive measures in food poisoning, etc. By doing all these, we can have good nutrition, a key to good health.

2. The Role of Nutrition in Human Health

Our body requires many different nutrients so that it can function properly. Nutrition is important in maintaining good health. Also, when you have a balanced diet, it prevents you from malnutrition and you will have good immunity. Some people have different myths about good nutrition, such as eating less because they want to lose weight. This is a wrong concept because when you eat less, you will have fewer nutrients and this will cause various illnesses. By definition, nutrition is the study of nutrients in food, how the body uses them, and the relationship between diet, health, and diseases. Nutrition focuses on how diseases, conditions, and problems can be prevented and reduced with a healthy diet. Likewise, good health is not about reducing the risk of a disease. It means physical, mental, and social well-being. Good nutrition is vital to good health. With such a fast life we are living in, it is easy to make the wrong food choices. Every day we make choices about the food we eat and our lifestyles. We can make the right choice and improve our healthy living right now. We have many advancements in the food market and much more good research. With advancements in nutrition studies, we discovered many ways to improve our health and also prolong our life. By having healthy food, getting enough nutrients, and having a regular amount of physical activity, we will promote our healthy living. We will look good, feel good, and live longer. Now, a proper diet is more important than ever. With the studies in the nutrition field, many books and food experts have come out to help people learn about what is good for health. We really have a big amount of research and if the government continues to invest in our nutrition research, we may have even more reliable information to improve our health. Many governmental departments are now working with nutritionists and food experts to unfold the secret of nutrition. This cooperation will not only help the country in healthcare but also improve the better life to the world. Also, some other actions may be taken to help people eat more healthily. Nowadays, it is becoming a public concern about the dangers of climate change and many people start to rethink what they consume and how their choices impact the environment. So, nutritionists or news articles could be published on presenting nutritious, eco-friendly diets and their benefits over our health. By taking some suggestions from the news articles, more campaigns could be held in promoting the awareness of the importance of good nutrition. For example, the government could organize farmers’ markets to promote locally grown fresh fruits and vegetables. Such campaigns could provide knowledge to the public and help them make changes. Every person, from the youngest child to the oldest adult, deserves access to the kind of diet that is going to protect and preserve their health. We must never stray from the belief in the meaningfulness of good nutrition. Good nutrition keeps good health. A proper diet provides a sufficient amount of nutrients and phytochemicals that help us keep good health. Nowadays, many people have been consumed by fast food. Most people think that fast food is fast, cheap, and convenient. However, research has revealed that fast food is not beneficial to human beings. This is because fast food is high in calories but low in nutrients and this can cause many bad effects on health. Many doctors and experts have spoken about the bad effects of fast food, but the huge number of fast food eaters does not seem to slow. In fact, research has found that the amount of fast food eaters has increased and this is reflected in the increasing number of fast food restaurants. No matter what age, nutrition is essential to maintain good health. Also, studies have shown that even improvement in nutrition could have a beneficial effect on our health. It can enhance or influence our behavior, our well-being, and also the length and quality of our life. Let us take action and start a healthy diet, and prevention will be better than cure.

3. Common Nutritional Disorders

When the body doesn’t receive the nutrients that it needs to perform a certain task, a specific kind of disorder can take place. The lack of proper nutrients is one of the reasons for such disorders. Perhaps the most famous nutritional disorder is scurvy, often associated with pirates and sailors who went for long sea voyages without access to fresh fruits and vegetables. Scurvy results from a deficiency in vitamin C, which is essential in making collagen. Collagen is a substance which holds connective tissues and cells together. Therefore, vitamin C is essential for firm skin, muscles, bones, cartilage, and blood vessels. Symptoms of scurvy include weakness, anemia, spongy and bleeding gums, skin hemorrhages, swollen joints, and the opening of previously healed wounds. In children, an extreme lack of vitamin D can cause a condition called rickets. Vitamin D is needed to help the body absorb and use calcium. Children with rickets can experience delayed growth, weakness, muscle pain, bowed legs, and soft, pliable skull bones, a condition known as craniotabes. On the other hand, lack of vitamin A results in a condition known as night blindness which should not be confused with complete blindness. When current treatments do not heal the disease, lack of medical expertise and access blinds millions of people. Lack of vitamins can cause diseases known as hypovitaminosis diseases. For example, insufficient intake of vitamin A leads to night blindness and a weakened immune system; a lack of vitamin D leads to deformities and poor growth. In many cases, adequate intake of the lacking vitamin will improve the symptoms. However, taken in excess, vitamins can have toxic effects. The adverse effects of consuming too much of a vitamin depend on the particular vitamin and can be quite serious. For instance, an excess intake of vitamin A is particularly toxic and can cause headache, vomiting, loss of hair, and dizziness. Similarly, too much vitamin C from supplements can also be quite harmful. High doses of vitamin C can cause indigestion and an increased risk of kidney stones. Excess vitamin C in the body is excreted through the urine, but this increases the risk of kidney stone formation by raising the levels of calcium in the body. On the other hand, an excessive intake of vitamins is very rare as they are difficult to get through diet alone. However, exposure to massive amounts from food or vitamins may be toxic. For instance, consumption of a large amount of niacin may cause a vasodilatory effect which can result in redness and a tingling sensation. It may also cause liver damage if there is a history of hepatic diseases. Dosages higher than 500 mg a day have caused flushing of the height with more serious problems at higher doses. High intakes of vitamin D can cause dehydration, vomiting, and abnormal amounts of calcium in the blood. Oral consumption of a high dose of vitamin A causes dizziness, nausea, headache, and can even lead to unconsciousness and death. Vitamins are essential to life. Every function of the body is controlled and regulated by vitamins. Like hormones, vitamins are powerful substances which have to be carefully regulated, not consuming too much or too little. A certain vitamin deficiency will lead to a specific kind of disease. For instance, a lack of vitamin D may cause a malformation of bone, known as rickets, which does not develop in the presence of vitamins.

4. Strategies for Promoting Healthy Eating Habits

Rigorous public health marketing campaigns have been developed around the world to promote a healthy diet and existence, in an attempt to curb the emergence of nutritional disorders and to ensure the global population can achieve and maintain health and well-being. For instance, Change4Life is a public health program in the United Kingdom that aims to help families and children to eat well, move more and reduce excess sugar intake. Through the utilization of upbeat signage, literature, and digital sell, the campaign employs a multifaceted approach to educate the world about the benefits of a balanced diet and active lifestyle, as well as providing concrete suggestions on how to achieve such a lifestyle. Indications of such initiatives are that they may be bearing success in increasing awareness and gradually modifying eating habits of a population. This section is perfectly bound up to what has been previously discussed, which is the strategies that can be employed to promote healthy feeding habits. A variety of different methods, encompassing legislative, public health campaigns, and advanced engineering solutions have been examined and it’s a heartening sight to see that many nations have already taken constructive measures to address the planetary health occasion. For instance, taxes on high sugar and high-fat food and drink have been introduced in many countries across Europe. Such taxes would increase the cost of these products, for why it would lead to a decrement in the quantity demanded, particularly for price elastic goods. Besides, these revenues can be put back into the health system to alleviate the fiscal pressing on handling obesity-connected illnesses. Such legislative measures have been implemented in the UK and in 2018 the sugar tax has already raised around £154.9 million for the government, impressive proof that supports the potency of taxation in reducing excess ingestion of stubborn food. These data were revealed in sugar tax income extra data 2018 to 2019 which was publicized by the UK government. Synergistically, restrictions on calendar marketing and television are also often mentioned because controlling the inducement to buy in young children and reducing the constant reminders of bad food can really help to change purchasing habits. However, there are no ready-made solutions when it comes to controlling the diet of a population and it is essential that the stakeholders from the government, the food industry, and the nonprofits come together and research how to effectively deal with the nutrition-related issue. It is worth noting that the technological progression and the automation which enable the collection of a big amount of accurate nutritional intake data are providing new opportunities for the development of advanced engineering solutions in promoting a healthy feeding regime. For example, smartphone apps can now help to track nutritional content of meals and direct the users to the nearest health food supplier, which may step up the accessibility of healthy options for those who are engaging with such engineering. Such personalized and user-friendly advanced engineering can be sustained by policies that promote the synchrony between health and technology, as well as funding for the consulting and collaboration between the engineers and the nutrition experts.

5. Conclusion

Nutrition is the science of food and how the body uses it in health and disease. It includes the processes by which the organism ingests, digests, absorbs, transports, and excretes food substances. These include food storage and anabolic and catabolic processes. It also includes the study of the most important classes of food such as carbohydrates, lipids, and proteins. Proper nutrition corresponds with good health. It is widely agreed in the community that we humans cannot resist the temptation of fast food because it is not properly supplied with vitamins and proteins. On the other hand, we can provide our body with all its necessities to be at a healthy state. Cells and molecules are continuously worked on, and in turn, the immune system is on full alert, bad cholesterol is reduced, and the burden on the heart is reduced. In this study, we have seen that various topics were covered. We started by exploring the background of nutrition. Then, we saw how nutrition is used for growth and development. After that, we saw how nutrition is used for supporting different body systems. Subsequently, we looked at the various nutrition disorders. We also described what is undernutrition and malnutrition. Finally, we have seen that the immune system is found to be strengthened because attention and attendance to the meals have been given, and enough energy and vitamins have been obtained. What’s more, the lack of nutrition has been reduced, which “The age of getting sick is becoming younger and younger nowadays” can be tackled. Overall, it shows that proper nutrition can lead to good health outcomes. For example, it is able to strengthen the immune system, speed up the recovery process, give more energy, reduce the risk of developing chronic, healthy, and heart diseases, and keep the body in good condition. Therefore, people should pay more attention to providing only good quality food with enough vitamins and minerals to maintain good health.
