Context: Diet and nutrition

Diet and nutrition are two concepts that are often used together. However, in healthcare and medicine disciplines, there is a distinction of the two words. Diet is the total amount of food substance ingested by a human being within a specific period. Diet description includes the type of food consumed by a particular person. On the other hand, nutrition describes the type of food consumed by an individual and the reaction of the human body to the food. Thus, nutrition investigates the effect of diet on the human body. Nutrition is concerned with the effect of food substances on cell physiology and metabolism. The nature of these responses determines the long-term effects of a particular diet regime. Concepts of diet and nutrition are important in nurturing healthy individuals. A balanced diet consists of the types of food that ensure that a particular person’s body is healthy. The specific diet that is considered healthy for a particular person is usually unique. Age, body mass, genetic factors, and lifestyle are some of the factors that affect the diet that each person requires to remain healthy. However, for average people, diet specification varies slightly particularly due to body size and genetic variation. There are certain food substances whose excessive consumption is known to cause disease or ill health. However, there is no single food substance capable of maintaining good health in an individual. Thus, a combination of food substances is necessary to ensure that an individual is healthy. The traditional perspective of nutrition is that the best diet regime is aimed at avoiding under-nutrition while also keeping weight gain under control. This perspective generalizes the effect of poor nutrition. It has a narrow scope regarding the effects of poor nutrition. Emerging issues in the science of nutrition indicate that diet is a major determinant of the possibility of development of chronic diseases in future. Chronic diseases are responsible for much of the mortality around the world. Although there is an association between diet and the immediate state of health of an individual, recent scientific studies imply that diet determines the probability of occurrence of chronic diseases in future. Several factors affect the diet needed for each individual. Physical activity is a major determinant of diet. In addition, increased physical activity improves cardiovascular health and requires more intake of specific high-energy food in the diet. Similarly, less physical activity requires consumption of food with low energy content. Thus, diet and nutrition are applied in a unique manner to each individual. Traditionally, diseases that develop due to improper diet and nutrition were considered non-communicable. This means that these diseases cannot be passed on from one person to another. However, recent research studies conclude that since risky behavior can be spread among individuals, the risk factors can also be spread through the behaviors. In that essence, chronic diseases that develop due to diet imbalance and malnutrition are communicable. Several current nutrition trends have been adopted for the health of an average normal person. Recent scientific studies show that consumption of whole grains has an effect of lowering the occurrence of chronic diseases and cardiovascular disorders. Whole grains contain fiber that is similar to that found in vegetables. Consumption of refined foods such as over-processed grains is one of the major contributing factors to development of diabetes among adults. This disease is responsible for significant portion of the total number of deaths in the world population. However, mixing whole grains with processed grain undermines whatever benefit the consumption of whole grains might have. This practice is only effective when one maintains a habit of consuming food that has undergone minimal processing. While observing a healthy diet regime is an important practice for good health, it is also necessary to limit the amount of food consumed. When one eats more food than is necessary for normal metabolic processes, the body converts some of it into fat, which is stored around body organs and under the skin. Some of the carbohydrates that are difficult to metabolize may settle within the vascular system. Deposits of carbohydrates in the vascular system lead to inefficient cardiac action. The heart and the lungs are suppressed by pressure from narrow vascular vessels. This is the cause of many diseases ranging from hypertension to heart disease. Disorders such as heart failure and stroke are the ultimate result of continued suppression of the heart and the lungs. It is important to avoid fatty food and excess sugar in the diet. Fat, particularly the unsaturated type that often occurs in products of food processing, poses danger to any individual who consumes it in large quantities. These fats are called trans-fats, and are responsible for coronary thrombosis. This is the gradual blockage of the coronary artery, which eventually results in heart failure. On the other hand, sugar has similar effects to those of the unsaturated fats. When the body has determined that the sugar in the blood is more than the amount required for respiration, some of the excess sugar is converted into fats and may deposit on the walls of the arteries. This leads to development of diseases similar to those attributed to high fat intake. In addition, excessive consumption of sugar is known to contribute to development of diabetes. Although the development of diabetes has many contributing factors such as weight, daily activity, and the genome of an individual, it is becoming increasingly evident that excessive fat and sugar in the diet are some of the prime factors that contribute to its occurrence. Traditionally, deficiency of vitamins in the diet was the main issue concerning the importance of vitamin intake. However, modern nutritionists argue that the choice of vitamins that are to be consumed in abundance also determines the possibility of development of diseases. Some vitamins such as vitamin E are natural antioxidants. Such vitamins inhibit the oxidizing action of some radicals in the body. This oxidation is responsible for some aspects of aging and some diseases of the neural system in human beings. Thus, the intake of these proteins in abundance is proving to be a useful strategy in establishing a healthy neural system and avoiding disorders such as stroke. Another emerging trend in the food industry is the practice of supplementing natural food with nutrients by food-processing industries. While some manufacturers are supplementing their products for genuine health benefits, others are doing it to match the competition for healthier food. Some of this supplemented processed food is proving to be useful in treatment of nutritional deficiencies and prevention of some diet related diseases. However, it is important to seek a doctor’s or a nutritionist’s advice before developing a habit of consuming such food. Although the use of modern pest control methods leads to production of more food, organic foods are growing popular with nutritionists and experts in the field of medicine. This is attributable to the fact that the effect of use of herbicides and pesticides is minimal in these foods. If it were possible for one to consume a significant proportion of organic food in the diet, it would help in avoiding chronic disorders and cancerous growths. Chemicals that are often used in production of some foods contain carcinogenic substances that cause growth disorders and cancer. Nutritionists are of the opinion that consumption of fresh food is also important for maximum nutritional benefit. Some nutrients become denatured if food is stored for a long time. Vitamins such as vitamin C are denatured a short while after harvest of food. Thus, early consumption ensures that most of the nutrients are absorbed into the body. Some substances known as omega-3 fats have been found to be beneficial to human physical and mental development. These substances are exclusively available in fish products. This means that if a person is to benefit from the use of these fats, he or she has to include fish in the diet. However, since fish is not a popular food product, food-processing firms are now adding this nutrient to other processed foods. To obtain the particular nutrients, one does not have to consume fish products. The discussed diet and nutrition trends are some of the recent recommendations by health nutritionist. They reflect the changing field of nutritional science, which is moving away from the quantitative to the qualitative aspect of nutrition. This is because the qualitative aspect of diet is proving to be more influential on human health than quantitative aspect.
