The Essential Role of Fats, Carbohydrates and Proteins While Dieting
Any effective diet cannot be complete without the correct intake of carbohydrates,
proteins and small amounts of fat. Most of us associate carbohydrates and fats
with weight gain, but this is in fact a preconception. A proper balanced diet is
essential for our overall mental and physical health, and should include the
nutrients contained in all of the six main categories of food, being carbohydrates,
proteins, vitamins, minerals, fats and water elements. Each component has a specific
role in providing vital nutrients our body needs for energy, cell and muscle
construction and other major functions.
As a general rule, when planning your diet you should aim at a daily intake of
around 15% protein, 30% fat and 55% carbohydrates. Don't worry too much about
the mathematics of dieting though. The percentages are a general rule of thumb and
you will be fine so long as you follow general healthy principles! What is important
is to learn how to recognize the proper sources from which to reap all the essential
nutrients to keep you healthy.
The aim in dieting is to try and consume lean proteins and wholegrain carbohydrates
wherever possible, whilst minimizing saturated fats and sugar. Most of your fat
allocation should derive from unsaturated fats, which are the ‘good fats’
necessary for the correct functioning of our metabolism.
Which food types contain ‘good fats’ and why are they important while
dieting.
We need essential fatty acids for cell reproduction and preservation of our nervous
system. When dieting we should limit the total fat intake to less than 25–35
percent of our total daily calories. When cooking or seasoning your food, opt for
mono unsaturated fats present in most seed oils. These oils are also rich
in omega 3 fatty acids, which will help keep our cholesterol levels low.
The best sources can be found in seafood, walnuts, flax, canola oil, pumpkin seeds
and soy. Reduce the amount of saturated fats, notably animal fats, such as
red meat, butter, lard, cream, milk, cheeses and other dairy products made
from whole milk. Avoid saturated vegetable oils such as coconut and palm oil,
often referred to as tropical oils.
The essential role of proteins and where to find the best sources.
Proteins are necessary, as these nutrients supply the body with the essential
amino acids for the production of cell and muscle tissue. When planning to
reduce the calories in a diet plan we should calculate that proteins must be
present in around 15% of our total daily calorie intake. Consume lean meats,
such as poultry and prefer fish to red meat in general. You can also find
high sources of protein and fibre in food types such as lentils, soybeans,
kidney beans, walnuts, eggs and low fat dairy products.
Why do we need a high percentage of carbohydrates in our diet?
An adequate level of carbohydrate intake will provide us with the fundamental
source of energy we need to function properly. Getting around 50% of your daily
calorie intake from health carb sources is a good target. The larger percentage
of carbohydrates should be obtained from ‘complex’sources with low
calorie content, including vegetables, cereals, rice and pasta. The healthier
amongst these being wholegrain products that are also an important source of
calcium, fibre, iron and vitamin B. Without carbohydrates we cannot find the
energy to carry out our daily tasks and any exercising we had planned to help
lose that extra weight.
Try to include all food types in your diet, especially fruit and vegetables.
