Diet which contains 80% to a good health is the amount of food we consume and
the word diet often implies the use of specific intake of nutrition for health
or weight-management reasons. Dietary habits are the habitual decisions an
individual or culture makes when choosing what foods to eat. This may be due to
personal tastes or ethical reasons. Individual dietary choices may be more or
less healthy.
Proper nutrition requires ingestion and
absorption of vitamins, minerals, and food energy in the form of carbohydrates,
proteins, and fats. Balanced Diet plays a significant role in the quality of
life, health and longevity. It can be define as consumption of all the classes
of food in the right proportion.
When we remove the “T” at end of the word “DIET”
it means DIE which implies that most people actually eat to die and not live, that’s
why it is very necessary we balance our diet always
WHAT MAKES A BALANCED DIET?
A balanced diet means getting the right types
and amounts of foods and drinks to supply nutrition and energy for maintaining
body cells, tissues, and organs, and for supporting normal growth and
development.
World Health Organization (WHO) uses an
illustration called the CHAIN OF LIFE to represent this
Among these six nutrients, which one do we
eat more?
The answer: Carbohydrates and protein. Our
diet lacks the other four nutrients.
Among the six nutrients, which one is more
important? LIPIDS and STEROLS
Lipids and Sterols feed our cells and make it
more permeable for nutrients.
Example of healthy cell with lipid and sterols
Nutrients gets in and waste gets out easily
Example of unhealthy cell without lipid and sterols
Nutrients can't get in and waste can't get out either
There are certain things a healthy cell contain that actually makes it healthy while there certain things unhealthy cells also contains that makes it unhealthy
Percentage
as to how we should take these nutrients
Fat and Carbohydrate (Sugar) - 5%
Proteins - 15%
Fruits & Vegetables - 30%
Whole Grains - 50%
Below is a healthy food pyramid
Fats and Carbohydrate
Eat
little because it is dangerous to health. The end product of carbohydrate is
Sugar
Many
people believe that weight gain is mainly due to eating too many
carbohydrates. In fact, people gain
weight because they eat too many calories, which is not the same thing:
calories come from carbohydrates (4 calories per gram), proteins (4 calories per
gram) and fats (9 calories per gram). Most people consume too many refined
carbohydrates such as white bread. We tend to eat more of this because of the
fact that its more cheaper and easier to get.
Eating
simple carbohydrates such as cake, candy and chocolate causes the body to
experience rapidly fluctuating glucose levels. Studies have shown that these
sudden changes in glucose can make you feel hungrier faster than normal. The
increase in appetite can also cause overeating at the next meal; studies suggest
calorie intake increases by 150 to 500 calories after glucose fluctuations.
Eating too many carbohydrates can contribute to weight gain. In a normal diet,
carbohydrates are broken down in the body and used as energy. Any excess
carbohydrates are stored as blood glucose. Your body can only hold so much
glucose, so once your glucose store is maximized, the excess glucose is
converted to fat, and unwanted weight begins to appear.
Beyond
the issues of weight gain, appetite control, and energy levels lie serious
health concerns associated with eating too many. Insulin is the hormone in the
body that is used to control glucose levels after eating carbohydrates. Insulin
resistance occurs when the body is so flooded with insulin that the body
becomes immune to insulin levels. This causes the body to think that it needs
more insulin. As the body continues to produce excess insulin, the excess is
stored in the blood, which can lead to Type 2 Diabetes. Other effects of
insulin resistance can include high cholesterol and high blood pressure. There
are no outward symptoms of insulin resistance, but a blood glucose test can be
used to determine if someone is insulin resistant.
Although
eating carbohydrates in excess can be damaging to your health, it's important
to keep in mind that healthy sources of carbohydrates, such as whole grains,
fruits and vegetables are an important part of a balanced diet.
In
addition, while there may be good reason to prevent rapid rises in blood sugar,
especially for people with diabetes, simpler advice includes avoiding refined
carbohydrates and empty calorie foods, and consuming plenty of fruits,
vegetables, legumes and whole grains.
Simpler advice also includes limiting calories and portion sizes if
weight control is your goal. In short,
you can eat a healthy diet without ever having to consult a nutritionist.
Protein
Eat little: protein has high cholesterol which is dangerous to health.
Health
Benefits
Proteins
are the building blocks of any living organism. They are composed of chains of
20 different kinds of amino acids. Proteins constitute life in the form of
enzymes, antibodies, hormones, hair, nail, bone, teeth, hemoglobin (blood
protein), neurotransmitters, skin or as the basic components of any cell in our
body.
Proteins
are indispensable for growth and maintenance of every kind of cell in our body.
Body development, replenishment of lost blood, healing of wounds and scars, replacement
of dead cells, and hair and nail growth need proteins. Proteins in the form of
enzymes, hormones and antibodies promote healthy metabolic and physiological
processes, and boost our nervous and immunity systems. In situations when fat
and carbohydrate food sources are not providing adequate calories, proteins are
degraded to generate the calories our body needs.
The
8 essential amino acids that we need to intake through our diet
Tryptophan
Helps
with the production of serotonin, promoting health sleeping patterns; combats
depression, stabilizes mood, alleviates stress, assists weight control and aids
in the control of hyperactivity in children.
Lysine
Essential
for bone growth and development (especially in children), maintains the body’s
nitrogen balance, assists in absorption of calcium, helps to produce enzymes,
hormones and antibodies and aids the recovery of surgical procedures and
sporting injuries.
Methionine
A
great antioxidant, which aids digestion, muscle strength and helps to prevent
brittle hair and fat build up in the liver and arteries.
Valine
Maintains
the body’s nitrogen balance and helps with tissue repair and muscle metabolism.
Leucine
Helps
to repair damage to the skin, bones and muscles, and therefore a great aid to
recovery after undergoing surgery.
Isoleucine
Delivers
energy to the muscles.
Threonine
Another
amino acid that hinders the build up of fats in the liver; it also helps your
body to sustain the correct balance of protein.
Phenylalanine
Synthesizes
the neurotransmitters dopamine and norepinepthrine, which help us to stay
alert; phenylalanine improves mood, memory and learning capacity, helps to
alleviate pain and also acts as an appetite suppressant.
Sources of Protein
CHOLESTEROL
We
all know that protein is supposed to be good for us, but what does it do
exactly? Protein is essential for a balanced diet, because it builds muscle and
collagen. According to the director of health promotion & communication at
Harvard University, Dr. Lilian Cheung, protein is the building block of
enzymes, hormones, immune factors and many other molecules that are critical to
the body. Harvard’s online magazine, Nutrition Source, states, “Adults need a
minimum of one gram of protein for every kilogram of body weight per day to
keep from slowly breaking down their own tissues.
Back
in 1983, researchers first discovered that eating more protein increases your
"glomerular filtration rate," or GFR. Think of GFR as the amount of
blood your kidneys are filtering per minute. From this finding, many scientists
made the leap that a higher GFR places your kidneys under greater stress.
This goes to red meat lovers as well as for fish fanatics and egg
enthusiasts: because a healthy diet doesn't have to be restricted to
chicken breasts and grain burgers. Grilling a lean slab of beef tenderloin
without heavy sauce or greasy sides is a good way to get protein. And though
eggs have been frowned upon in the past, they can actually be a good addition
to a diet, as long as the yolk, which contains the bulk of fat and cholesterol is
removed
Here are few examples of what we are talking
about
Your
body makes cholesterol, and you get it also when you eat eggs, meats, and dairy
products. When you have more than your body needs, cholesterol can cause plaque
to build up in your arteries. This thick, hard plaque can clog your arteries
like a blocked pipe. Reduced blood flow can lead to a stroke or heart attack.
Cholesterol
Hazards to the body
If
there is a clog in a coronary artery, your heart gets too little blood and
oxygen. Without enough oxygen, your heart becomes weak and damaged. If the
plaque breaks open, a blood clot may form on top of the buildup, further
blocking blood flow and a blood clot can also break off and flow to an artery
in another part of the body. If a clot completely blocks an artery feeding your
heart, you have a heart attack.Plaque
buildup can also keep your brain from getting enough blood and oxygen. If a
clot completely blocks an artery feeding your brain, you have a stroke
