ROLE OF ANTIOXIDANTS IN GOOD HEALTH

May 13th, 2009

By - Dr Deepika Malik

 

When we breathe, we take in oxygen. This oxygen brings about a chemical reaction in our cells called oxidation, which is a byproduct of normal metabolism. The result of oxidation is the formation of molecules known as free radicals, which can damage cells and tissues in the body, leading to certain cancers, heart diseases, and other illnesses. Antioxidants help to clean up free radicals before they can oxygenate and cause harm to the body.

 

The following table describes various key antioxidants, their sources, and potential benefits.

Note: Because the study of antioxidants is new, the research is limited and inconclusive. There is no evidence that isolating antioxidants in a supplement offers health benefits or hinders the formation of free radicals. Most research suggests that it’s the combination of nutrients in whole foods that offer the most valuable source of antioxidants. Therefore from a public health perspective it is premature to make recommendations regarding antioxidant supplements and disease prevention. Perhaps the best advice, which comes from several authorities, is to eat 5 servings of fruit or vegetables per day.

NUTRITIONAL CONSIDERATIONS IN SCHOOL-AGED CHILDREN

March 12th, 2009

By Dr. Anshu Kumra

Nutrition that has major effects on health refers to the availability of nutrients to the body cells in relation to individual’s requirements. Malnutrition refers to any imbalance in satisfying nutritional requirements. Among children, malnutrition is often caused by the synergistic effects of inadequate food intake, repeated episodes of parasitic or other childhood diseases such as diarrhoea, and improper care during illness. Malnourished children are more likely to grow into malnourished adults who face heightened risk of disease and death.

Period from 5 years to adolescence is of slow but steady growth. The peak of growth is generally between 11 - 15 years for girls and 13 -16 years for boys. The more nutritious diet a child consumes, the healthier he or she would be. Here are some of the important guidelines for the nutrition of school–going children: -

  • The child should get a wide variety of healthy nutritious foods like green leafy vegetables, fresh fruits, legumes, nuts etc.
  • Ensure that the child eats enough cereals especially whole grains.
  • Milk and milk products are important for the growth of child, as they are a fabulous source of calcium necessary for healthy bones and teeth.
  • As far as intake of non-vegetarian food is concerned, encourage the child to go in for lean meat, fish and poultry.
  • Choose foods that are less salty and less spicy.
  • Avoid foods that are high in sugar and fat content.
  • Prefer the cooking techniques like steaming, boiling and baking, rather than frying.
  • Children need to drink plenty of fluids, especially water, as they are physically active.

Food habits: importance of regular eating pattern

Dietary habits are generally developed in early childhood and affect food preferences and nutrient intake, particularly during adolescence. The home and school environment plays a major role in determining a child’s attitude towards consumption of foods.

Stress and emotional upsets can seriously affect the food consumption in adolescents, resulting in too little or too much of food intake. Mild or severe infections, nervousness, menstrual, dental or skin problems (acne) can result in depression, and adolescents on marginal diets are the most vulnerable. Emotional stress is often associated with food faddism and slimming trends, both of which can lead to eating disorders such as anorexia nervosa. One of the most frequently missed meals is breakfast. Studies show that breakfast plays an important role in providing needed energy and nutrients after an overnight fast and can aid in concentration and performance at school.

Lack of physical activity not only leads to overweight and obesity in adolescence, but also results in the development of chronic diseases such as hypertension, diabetes, heart disease, certain cancers, bowel problems and osteoporosis in later life. Physical activity is important for flexibility, balance, agility, co-ordination, and strengthening of bones. Therefore, it is recommended that children must indulge in some kind of physical activity for at least 60 minutes everyday.

Snacks generally form an integral part of meals for both children and teenagers. Younger children cannot eat large quantities at one sitting and often get hungry long before the next regular mealtime. Mid-morning and mid-afternoon snacks can help to meet energy needs throughout the day. Fast-growing and active teenagers often have substantial energy and nutrition needs and knowledge of nutrition will enable them to make healthy choices of foods in their regular meals and snacks.

As iron-deficiency anaemia is the most common diet-related deficiency disease during childhood and adolescence, it is important to increase the intake of iron-rich foods such as beans, dark green vegetables, nuts and iron-fortified cereals and other grains. However, Iron from animal foods such as lean meats and fish (known as haem iron) is better absorbed than iron from non-animal sources (non-haem iron).

The achievement of peak bone mass during childhood and adolescence is crucial to reduce the risk of osteoporosis in later years. The largest gains of calcium are made in early adolescence, between 10-14 years in girls and 12-16 years in boys. By eating several servings of dairy products, such as milk, curd and cheese, the recommended calcium needs can be met. Activities such as cycling, gymnastics, skating, ball games, dancing and supervised weight training for at least 30-60 minutes a day, three to five times a week can help build bone mass and density.
