If you are thinking this is about Maggi, you are not quite
right. Taste and health seldom go
together but milk is something that can be savored and is still healthy. It is
tasty and healthy. Right from birth, milk plays an important role in human
growth and well-being.
Be it an infant or an aged person, milk is essential. The role of
milk differs with each stage of life. While milk is the sole food for an
infant, it gradually turns into an important nutrient with the demands of
growth and aging placing differing needs on milk.
Let us look at:
MILK REQUIREMENT DURING EACH STAGE
Birth-12 months : 16 ounces – 45 ounces (1 ounce is 30ml)
1-2 years : 16-24
ounces (AAP recommendation)
> 9 years :
24
ounces (USDA)
Teens and Adults : 32 ounces
The only safest natural food
available for a newborn is the “Breast Milk”. It is packed with lot of nutrients,
antibodies and growth factors. Complimentary foods should be introduced after
six months of age. This is because breast milk alone cannot meet the
nutritional needs of the growing infants. However breastfeeding can still be
continued up to 2 years. RDA: 500mg of Calcium/day. Most toddlers are
fussy eaters especially when it comes to drinking Milk. Macronutrients play a
major role in the growth and development of every child. Toddlers definitely need to drink milk
especially whole milk because they require that fat for brain development. American
Academy of Pediatrics (AAP) recommends 480-600ml of whole milk/day.
Milk is also rich in protein and calcium thus ensuring adequate growth and bone
development. Carbohydrates provide the necessary energy. Proteins help in body
building and enhance the immune system. Fats are required for the absorption of
fat soluble vitamins A, D, E and K. It also has an insulating effect on the
nervous system. RDA: 600mg/day
Rapid growth occurs during
adolescence period. Hence adolescents need additional nutrients to meet their
demand. Achieving a high calorie, high protein diet along with essential
vitamins and minerals through diet is very important. This is to aid in growth
and to encourage physical activity. Adolescents should be encouraged to boost
their calcium intake through milk and milk products for healthy bone growth. RDA:
600mg/day
Milk is a very good source of calcium but not all teens like to
drink milk. The calcium requirement for teens is 800mg/day.
Pregnant mothers too require
calcium in a higher amount to meet the needs of the growing fetus. Milk is one of the important sources of
dietary calcium and hence avoiding milk intake would lead to bone demineralization.
Pregnant and lactating mothers require 1200mg of calcium/day.
Ageing is a natural physiological
process. Elderly are more prone to
fractures due to age related decline in the bone mass. According to the Harvard
School of Public Health, annually 1.5 million people over the age of 50 have bone
fractures and 300,000 of them have hip fractures. If you are worried about the
fat content of milk, you can choose Non-Fat milk which still contains a good
amount of calcium than the regular milk. RDA: 600mg/day
NUTRITIONAL ROLE OF MILK
CALCIUM
Milk and Milk products are important
sources of dietary calcium. The major function of calcium is to develop and
maintain healthy bones and teeth. In addition to that, it helps in blood
clotting and muscle contraction.
VITAMIN –D
Vitamin D is important for the absorption
of calcium. Its deficiency leads to
osteoporosis, rickets (in children), impaired immune function etc. Vitamin –D
Non-Fortified milk provides only 10% of the daily value.
CHOLINE
This nutrient is required for the normal
functioning of all cells and plays a vital role in nerve transmission. It also
enhances learning and memory.
POTASSIUM
Potassium is needed to maintain normal
blood pressure. It maintains the acid base balance which is very essential to
keep our vital organs stay fit. It also controls the activity of heart thereby
reducing the risk of heart disease.
VITAMIN B-12
It is otherwise called Cobalamin. It is
essential for the formation of red blood cells and its deficiency leads to
pernicious anemia.
VITAMIN –A
It is a fat soluble vitamin. This vitamin is required for normal vision,
cell growth, maintenance of healthy skin and enhanced immune function.
CARBOHYDRATES
Provide instant energy.
PROTEIN
Aids in the body growth and tissue
repair. Helps in the synthesis of enzymes and hormones.
FAT
Provides energy. It helps in the
absorption and storage of fat soluble vitamins A (Proper vision), D (Absorption
of calcium and maintenance of healthy bones), E (Antioxidant activity) and K
(Blood clotting). It also has an insulating effect on the nervous system thus
it maintains the body temperature.
So, let’s make it a point to include
milk in diet and enjoy the taste and health.
