Food provides our bodies with the energy, vitamins, minerals, fats and building blocks of protein, enzymes and genetic material to live grow and function properly. However lower food intake has been observed in the elder people and it became critical risk factors for malnutrition, especially protein and micronutrients. This will increase the risk of developing several ages? related diseases.

Nutritional biochemistry is a discipline of nutritional science that encompasses the knowledge of nutrients and other food components with emphasis on their range of function and influence on mammalian physiology, health, and behavior. The knowledge obtained from nutritional biochemistry research forms the foundation for nutrition-based public health care and management.

Healthy diet is an important element of diabetes, along with exercise. A healthy diet is naturally rich in nutrients and low in fat and calories. Nutrition therapy plays a major role in diabetes and it helps in promoting healthy eating and assist in regulating glucose, lipid, and blood pressure levels.

Right nutrition from the babyhood of life is the backbone of a healthy lifestyle. Child's diet is vital to support their normal growth and development, apart from that it also enhances their immune system, and develops lifelong eating habits.

Probiotics are useful organisms, most of which are normally found in the healthy human gastrointestinal tract. Due to increased use of infection associated antibiotics, the beneficial microbiome present inside the digestive gut also gets affected. But thanks to the probiotics supplements, the prebiotics which complements the beneficial microbiome and preserves the beneficial microbial flora. Probiotics are generally defined with respect to bacteria and yeasts, broadly the strains Lactobacillus, Bifidobacterium, and Saccharomyces. Probiotic ingredients stimulate natural digestive juices and enzymes in the body to ensure proper functioning of the digestive system. They conquer potentially dangerous organisms in the intestine, reducing the risk of infection or toxin-mediated diseases. Probiotic products are available in various different forms worldwide, including pills, powders, foods, and infant formula. The probiotic arrangements utilized for explorer's diarrhea, anti-infection diarrhea and acute diarrhea appear that they have a positive therapeutic impact.

Nutrition has a significant role in different aspects of cancer growth and is a significant support therapy throughout the entire pathway of cancer treatment. Adequate nutrition support can help cancer patients keep up weight and maintain a fit body, offering better recovery from malnutrition and its side effects and improving quality of life.

Critical Care Nutrition is the means of providing safe and optimal nutrition to patients admitted to the Intensive Care Unit (ICU), using evidence-based practice. Early nutrition therapy may decrease disease severity, decrease complications, reduce the length of stay in the ICU and decrease mortality. It is one of the recent advancements in the health care sector.

Enteral Nutrition is nothing but tube feeding. It refers to any method of feeding that uses the gastrointestinal tract to deliver person calorie requirements. Parenteral Nutrition refers to a supplement of nutrition and calories into a vein. It helped an individual remain hydrated and possibly to provide calories to allow them for growth and development.

Sports nutrition combines knowledge of human nutrition and exercise science. Kinesiology refers to the study of human movement. It includes the concept of biomechanics, anatomy, physiology, and neuroscience. Both are Interdisciplinary research areas.

The common gastrointestinal disorders include constipation, irritable bowel syndrome, perianal abscesses, anal fistulas, perianal infections, hemorrhoids, anal fissures, diverticular diseases, colon polyps, colitis, and cancer. Many of these can be prevented or minimized by maintaining a healthy lifestyle. Nutrition treatment is found to be effective in the management of gastroenterology diseases.

Functional foods are those that have a potentially positive effect on health beyond basic nutrition. They have been found to promote optimal health and also help in reducing the risk of disease. Nutraceuticals is a food or part of a food that provides medicinal or health benefits like prevention and treatment of disease. Nutraceuticals can be either a naturally nutrient-rich or a medicinally active food.

Nutritional neuroscience is study that let us know about the effects of various components of the diet such as protein, carbohydrates, fats, minerals, vitamins, nutrients, food additives, and synthetic hormones on neurobiology, neurochemistry, behavior, and cognition of the brain. It also deals with the well-being of the mental state of a being.

A healthy pregnancy diet will promote the baby's growth and development. The major components of a healthy lifestyle during pregnancy: appropriate weight gain, eating a balanced diet, exercising regularly, and appropriate and timely vitamin and mineral supplementation.

Medical nutrition therapy is a therapeutic approach to treating medical conditions and their associated symptoms by the use of a specifically designed diet monitored by a medical doctor physician or registered nutritionist. The diet is designed based upon the patient's medical record, physical and functional examination and dietary history.

Nutrigenetics is basically to recognize in what way genetic difference affects response to nutrients. This evidence can be pragmatic to boost health as well as to inhibit diseases. The final aim of nutrigenetics is to offer people with modified nutrition based on their genetic character. Nutrigenomics includes studies about the effects of food components on gene expression for the advances investigation on discovery and understanding the molecular level relationship between nutrients and other dietary bioactive within the genome.
