CARBOHYDRATES
Carbohydrates are made up from sugars and have two main
groupings, simple carbohydrates (sugars) and complex carbohydrates
(starches).
As a nutrient, carbohydrates perform the important function of
acting as the main source of energy for the body. Carbohydrates are
found
in milk, bread, pasta, rice, sweets, cereals, fruits and vegetables.
Simple Carbohydrates are made up of single sugars called
Monosaccharides or two sugars joined together called Disaccharides.
Their composition and structure means they are broken down quickly
in the mouth and stomach. When eaten alone in excessive quantities
they can cause a rapid rise in blood sugar resulting from their quick
absorption into the blood stream, a sharp rise in insulin levels follows,
which in turn causes the sugar to be converted to fat. Another way
of explaining this potential problem is that a diet high in sugars
is likely to be high in calories, and these excess calories will be
stored as fat in the body. Also, sugary foods such as soft drinks,
chocolates, cakes, ladoo, jalebi and bakhlva are low in nutritional
value and vitamins and the main culprits in tooth decay. Try and limit
your intake of sugary foods and when you desire something sweet to
eat, choose a scrumptious fruit instead. Oranges, bananas, pears,
apples have the added benefit of being rich in fibre, vitamins and
minerals.
Complex Carbohydrates consist of many sugars joined together. Also
known as starchy carbohydrates, their makeup means they take longer
to be broken down in the stomach. Therefore, the sugars are released
and absorbed into the blood stream at a more gradual rate. Starchy
carbohydrates are the body’s favourite source of fuel. This
is mainly because glucose is the preferred source of energy for our
muscles, organs and brain and the main flow of glucose stems from
starch. Additionally, they are full of healthy nutrients like fibre,
vitamins and minerals. Hence, starchy carbohydrates are a critical
source of energy and should be consumed abundantly as part of a healthy
diet. Pasta, rice, fruit, potatoes, cereals, beans, noodles, bread
and vegetables have plenty of starchy carbohydrates.
