Nutrition & Health

Nutrition and food science have each improved the expansion of an abundant, nutritious, safe food supply. A healthy diet should comprise of all of the obligatory nutrients and adequate calories to balance energy spending and provide for growth and maintenance thru the life cycle. Significantly, dietary factors are linked with 5 of the 10 leading causes of death, counting coronary heart disease, certain types of cancer, stroke, noninsulin dependent diabetes mellitus and atherosclerosis. Nutrition is essential for Healthy Life Style Promotion and progression over the whole life expectancy. Great wellbeing is critical to carrying on with a profitable life, addressing vital needs and adding to group life, Nutrition stimuli to a Healthy way of life advancement. Importance of Food and Nutrition in Health is an inevitably essential preference for populations round the globe. Sustenance is gradually concerned with metabolic methods and digestion system, the organization of biochemical paces through which substances among living life forms change starting with one edge then onto the next.

Nutritional science is the study of how an organism is nourished, and includes the study of Nutrition and metabolism. Nutritional science shelters a wide spectrum of disciplines. Nutrients must be obtained from diet, since the human body does not synthesize them and are used to generate energy, notice and respond to environmental surroundings, move, excrete wastes, respire. Healthy food habit is becoming ever more of a science, with new research showing us which foods may decrease our risk of disease, and which are progressively pointed to as the culprits behind ill health. Researchers are looking to better recognise how nutrients work in our bodies, with studies that investigate the diets of people with heart disease, cancer, and other diseases, along with research aimed at helping people to lose weight, or maintain weight loss. There are various classes of nutrients such as carbohydrates, lipids, proteins, water, vitamins, and minerals which are required for the body to function and maintain overall health.

Pediatric Nutrition is defined as the maintenance of a well-balanced diet consisting of the vital nutrients and the sufficient caloric consumption which is required to stimulate development and withstand the physiological necessities at the numerous phases of a child's growth. It also includes Nutritional requirements in infants & children and various caring practices.  Due to deficiency of nutrition particularly during critical ages of growth, causes improper development or major illness, such as anaemia due to the deficiency of iron or scurvy due to lack of vitamin C. Nutrition plays a critical role in childhood development, which results in both good or bad. Proper nutrition helps in the appropriate growth and development of children allowing them to reach their complete potential.

Current research in Nutrition is screening which foods may inferior the danger of disease, and which are accountable for illness. Researchers across the sphere are looking for  better understanding  of Food Safety network, Food and nutrient intake dietary pattern and dietary guide, Food Quality, Safety and Sustainability. Current research is providing innovative information about the connection among nutrition and health.

The body needs different vitamins and minerals that are vital for both body development and preventing illness. These vitamins and minerals are called micronutrients. They aren’t manufactured naturally within the body; they are acquired through the intake of proper diet. Nutritional deficiency rises when the body is unable to absorb the vital amount of nutrients. Malnutrition occurs when the body is not getting adequate amount of the nutrients. Nutritional Lacks lead to a variety of Mental Disorders and Depression.
Nutritional deficiencies can be of different types-

• Vitamin deficiency
• Mineral deficiency
• Iron deficiency
• Calcium deficiency

These deficiencies may lead to certain critical as well as life threatening diseases.

Food Safety and standards  include handling, preparation, and storage of food in order to prevent food borne illness. This includes a number of procedures that should be followed to avoid severe health hazards. Food safety is taking care of, arrangement storage and hoarding of nourishment in ways that avoid food borne disease or potential contamination and spoilage.

Nutrition critically helps in the recovery of cancer patients. Clinical studies have highlighted the Importance of Nutrition in Cancer Care. Clinical nutrition plays an important part in keeping healthy nutrition balance in patients. Cancer treatment can affect one's diet, and dietary changes can deteriorate other treatment related symptoms. For example, cancer patients who experience chemosensory modifications, distorted taste, and increased sensitivity to smells because of the cancer itself or as a side effect of treatment those are more prone to higher levels of weight loss, decreased energy intake, and poorer quality of life. An unexpectedly high number of patients undergoing cancer treatment report alterations to their sense of taste & smell. It has been estimated that if diet, physical activity and weight management are compounded together then 30% of the cancers could be prevented.

Nutritional Therapy complies nutrition science in the advancement of healthy lifestyle. Renowned nutritionists use a wide range of tools to assess and recognize possible nutritional imbalance and understand how these may cause for an individual’s symptoms and health concerns. Nutritional Therapy comprises of food that prevent and reverse diseases that affect most western societies: diabetes, obesity, heart disease, arthritis, and depression. In order to make food therapeutic, it must be nutrient-dense, measured in part by the nutrients and anti-nutrients, contained in consumed foods.

The epidemic of childhood obesity is no longer restricted to high-income countries and has become one of the most significant global health problems of the 21th century. The World Health Organization (WHO) experts have assessed that there are 43 million overweight children under the age of 5 and by 2020 more than 60% of global disease burden will be the result of obesity related disorders. Childhood obesity is connected with several short term and long-term health hazards such as cardiovascular diseases, hypertension, type 2 diabetes, fatty liver disease, orthopedic problems, low self-esteem, etc. Childhood obesity can reduce life expectancy by 2-5 years. Moreover, the increasing trend of obesity has enormous economic outcomes. Nutrition deals with Obesity and its Treatment, weight management tips, and obesity related disorders. Behaviour Modification helps in prevention from obesity.

Plant nutrition is amongst the major divisions of nutritional science. Its main focus is on foods derived from plant sources. The field of Plant Nutrition provides Genetically Modified Crops which helps in prevention of numerous diseases. Nutraceuticals are derived from food sources which help to provide an additional health benefits. A nutraceutical may be defined as a substance, which has physiological benefits or helps in the prevention of major chronic diseases. Nutraceuticals may be used to improve health, delay the aging process, increase life expectancy, or support the structure or function of the body. Nowadays, nutraceuticals have received considerable interest due to potential nutritional, safety and therapeutic effects.

Nutritional epidemiology is a new field of medical research and is defined as an area of epidemiology that involves investigation to study the importance of nutrition in the etiology of disease and to monitor the nutritional status of populations.

Animal and Livestock nutrition deals with the study of Nutrition from Animal Source. Growing consumption of dairy and other livestock products is bringing important nutritional benefits to great sections of the population of developing nations. An optimal nutritional package should guarantee adequate intakes of amino acids, minerals, carbohydrates, fatty acids, minerals, and vitamins by animals through a supplementation package that modifies deficiencies

Parenteral nutrition is a method of receiving nutrition into body through veins. Various Methods of delivering parenteral nutrition are there which are helpful in transportation of nutrients such as sugar, carbohydrates, proteins and trace elements to the body. These nutrients are important in maintaining high energy, hydration, and strength. Some people only need to get certain types of nutrients intravenously as they are suffering from various diseases like Cohn’s disease, ischemic bowel disease etc. Some side effects are also there e.g. changes in heartbeat, confusion, convulsions or seizures, difficulty breathing, fast weight gain or weight loss, fatigue, fever or chills, increased urination, jumpy reflexes, memory loss, muscle twitching, weakness, or cramps, stomach pain, vomiting.

Clinical nutrition plays a significant role in disease prevention. It joins primarily the scientific fields of nutrition and dietetics. The main aim for clinical nutrition is to keep a healthy energy balance in patients, as well as providing sufficient amounts of nutrients such as proteins, minerals and vitamins. Nutritional Assessment, Parenteral nutrition and Nutrition Physiology comes under clinical nutrition.

Sports Nutrition is the study of nutrition and diet. It is concerned with the type and quantity of fluid and food intake by an athlete. Sports Nutrition deals with Nutrition and Health, Exercise, Energy balance, sports food and energy drinks and whey protein nutrition.

Nutrigenetics objective is to recognize in what way genetic difference affects response to nutrients. This evidence can be pragmatic to boost health, and inhibit diseases. The final aim of nutrigenetics is to offer people modified nutrition based on their genetic character. Nutrigenomics includes studies about the effects of food constituents on gene expression. This means that nutrigenomics is research focusing on finding and understanding the molecular-level interaction between nutrients and other dietary bioactives with the genome.

Maternal nutrition is of prime importance in foetal growth and development. Nutrition in pregnancy refers to the nutrient consumption, and dietary scheduling that is commenced before, throughout and later pregnancy. Maternal under-nutrition during gestation reduces placental and foetal growth. Present studies revealed that the nutrition of the mother will have a consequence on the child, including the risk for cancer, cardiovascular disease, hypertension and diabetes throughout life.

Medical nutrition therapy helps in prevention of diabetes. Nutritional Therapy is integral component of diabetes self-management education. Diabetes mellitus is a collection of metabolic diseases in which there are high blood sugar levels over an extended period. Symptoms of high blood sugar include frequent urination, increased thirst, and increased hunger. Proper Diabetic Meal Plan should be followed in order to prevent diabetes. If left untreated, diabetes can cause many complications.

Iron deficiency  is among the most widely found  nutritional deficiency among the world, which further leads to Anaemia, a blood disorder that causes fatigue and variety of other indications. Poor nutritional status leads to poor health and a number of diseases like HIV/AIDS, Congestive Heart Failure, Diabetes, Kidney disease, Alzheimer's disease and Parkinson’s disease.
