WHAT ARE THE NUTRITIONAL REQUIREMENTS FOR ADOLESCENCE

 


The period between childhood and youth is called teenage. This period of transition from childhood to adulthood is also known as Adolescence. During this time physical,  bio-chemical,  and emotional changes has been accelerated.  Our weight, height and even our physical structure also changes.  This is a time period between 12-18 years of age. 

The extremely rapid and sudden increase in growth rate during this time is known as growth spurt. The growth spurt of boys is slower  than that of the girls. Several physical changes occur in our body followed by several physiological changes as well. The limitation of menstrual bleeding in adolescent girl is a significant change that create a tremendous nutritional demand. 

Just have a look : physical changes in puberty


The Nutritional requirements of adolescents:-

v Energy: As growth rate increases, the calorie requirement also increases. Girls generally require fewer calories, although individual demands vary. The appetite usually in boys, increases and so it is usually not difficult to meet the high calorie demand.

v Protein: The protein needs represent 11-12% of energy intake. The protein intake usually exceeds 1gm/kg body weight. This meets growth needs and for the pubertal change in both the sexes and for developing the muscle mass in boys. The protein requirement in girls, between 10-12 years, is higher compared to boys. High biological value protein should be given.

v Fats: Essential fatty acids should be given to the adolescent which should provide at least 3%. The desirable level for the visible fat intake for adolescents is 20 gm/day. α – linoleic acid is beneficial to reduce abdominal pain during menstrual periods and helps to relax muscles.

v Minerals: Calcium and phosphorus ratio of 1:1 should be maintained. Bone growth especially in boys, requires large amount of calcium. Iron is needed for blood formation. Girls loses about 0-5 mg iron/day during menstruation and for this iron supply is necessary through the diet. Zinc is also necessary for pubertal growth.

v Vitamins: All the fat soluble vitamins are required according to the RDA. Vit D is especially required for skeletal growth and calcium metabolism. The ‘calorigenic vitamins’ i.e  B1, B2  and niacin have to be supplied according to the energy intake. Folic acid and vit.B12 are needed for DNA synthesis since there is rapid cell division in adolescence due to the growth spurt. Tissue growth requires amino acids for which protein metabolism is needed. B6 helps in protein metabolism and also helps to reduce premenstrual stress in adolescent girls.

Other general dietary intake:

·       A well balanced nutritious food should be given to the adolescent which does not contain other excess or deficient quantities of nutrient, to prevent obesity and underweight respectively.

·       Regular meal time should be maintained and skipping of meal time should be avoided.

·       Junk and fast foods should be avoided.

·       Foods should be made attractive and appealing.

·       Media influence and emotions should not guide food intake.

·       Physical activity should be encouraged.

Lower part of the oesophagus.  2. Stomach (especially the lesser curvature or antrum). 3. First portion of the duodenum, also called the duodenal bulb.  Actiology: Pepitc ulcer results when the neural and hormonal abnormality disrupts the factors that normally maintain mucosal integrity and permit proteolytic and acidic erosion of the mucosal tissue. Factors affecting mucosa:  Destructive Facto...

Vitamin D - importance, source, deficiency, treatment

Vitamin D (calciferol) There are several compounds with Vitamin D activity occurring in several forms; this group of related Chemicals is together known as vitamin D.  So, vitamin D is a collective term for a group of compounds with antirachitic activity and includes ergocalciferol D2, cholecalciferol D3, and Dihydrotachysterol DHT2 and DHT3 together with their biologically active metabolites. Vitamin D is now believed to be a hormone. Vitamin D is considered to be a hormone rather than a vitamin because- 1. It is produced in the body from cholesterol, like other steroid hormones (estrogen, progesterone, etc). 2. It has a structure similar to the steroid hormone. 3. It's the mechanism of action that is similar to these hormones as well. 4. It regulates calcium metabolism and bone formation along with parathyroid hormone (PTH) and calcitonin (CT).  Since both these are hormones and Vitamin D acts synergistically with this it is considered to be a hormone also. Sources of Vitami...
