Nutrition 101
Nutrition 101 is
about the
familiar saying "You
are what you eat". Now more than ever, people are
focusing on nutrition to help them live healthier, longer and happier
lives.
Growing evidence suggests that many individuals suffer from diseases
that
can be
controlled or prevented through diet and lifestyle, and the last
fifteen years
has seen an explosion of research into the direct relationship between
nutrition and overall health.
For most of us,
as we age, we tend to gradually put
on weight.
But dangerous weight gain is not inevitable. Research shows that
individuals who consume a diet rich in whole grains, fresh
fruit, non-starchy vegetables and antioxidants live longer and
healthier lives.
It’
a medical fact that by eating better you can reduce the risk of cancer,
heart
disease and other diet related illnesses. Making
wise food
choices for yourself and your family will give you a sense of
satisfaction – a
sense of personal control over your own health that you may never have
had
before. Good nutrition
start with you!
Here are a few basic guidelines
of Nutrition 101.
1. Eat
Colorful Fruits and Vegetables

Fruits and vegetables should make up
80
percent of what you eat every day. The more colors, the wider variety
of
vitamins, flavenoids and antioxidants. A
wide variety of
fresh fruits and vegetables are important for optimal health because
each color
signifies a different health benefit.
Evidence shows that people on plant based diets live healthier and longer lives. Vegetables contains phytonutrients which researchers believe may help protect the body from cancer, heart disease and obesity. Eating the recommended servings of fruits and vegetables every day is the best way to get all the nutrition you need to stay healthy.
We all know that healthy eating takes time, preparation and money. With today's busy lifestyles it is easy to take short cuts and miss out on many of the important nutrients your body needs. Many times, the vegetables that we do eat tend to be over processed or over cooked so that the nutrients are lost. Learn the best cooking tips for your favorite vegetables that lock in the nutrients and taste great.
2. Eat
Whole Grains
Eating
a serving of whole grains such as barley or rye for
breakfast can help keep your blood sugar levels low for up to ten hours
according to a study conducted at Lund University in Sweden. The grains
contain
dietary fiber and a resistant starch that work together to slow
digestion and keep
you feeling fuller longer.
3. Skip
the Saturated Fat
Replace
fattening salad dressings with a homemade dressing of
vinegar
and oil. Just two tablespoons of vinegar on a salad can help you lose
up to one
pound a week. Researchers at the University of Sidney in Australia
discovered
that the potassium in vinegar helps reduce the post meal rise in blood
sugar by
up to 50 percent. Lemon juice has been shown to have a similar effect.
Eat
MUFAs - also known as monounsaturated fatty acids. Researchers
found that people who ate more nuts had a lower body
mass
index. According to researchers at Purdue, the MUFAs found in nuts are
are a
satisfying treat which can suppress the appetite all day long.
Of the
three main food sources, carbohydrates,
protein and fat, how much of each should we be eating? All three
macronutrients are essential to fuel the body - the key is to striking
a harmonious balance that is right for you.
Carbohydrates are the main
source of
energy
for the central nervous system, brain and red blood cells. They are the
only
nutrient the brain can use for fuel.
But not all carbs are created equal. The most important distinction among carbohydrates is whether they are simple or complex.
Most foods that contain
simple carbohydrates taste good but
they are not worth much from a nutritional standpoint and should be
avoided as much as possible.
Complex
carbohydrates
are the mainstay of a low carb diet because they
are
digested slowly which means glucose is released into the
blood
gradually.
Life would be impossible
without protein which is found in meat,
eggs, poultry, seafood, dairy and legumes. Protein ranks as the most
important nutrient the body needs, ahead of carbs and fat. Since
the body does not store proteins for later use, as it does with carbs
and fats, you have to continually replenish the body's stores.
. If you don't consume enough
protein, the body will wither and become weak. Proteins are the essential building blocks of the
body.
Most muscles, organs and hormones are comprised of
protein.
When
consumed, protein is broken down into amino acids which can then be
resused to make the proteins the body needs to maintain muscles, bones,
blood and organs.
Protein does not cause the sharp increase in blood
glucose levels that carbohydrates do.
Instead, protein produces a slower increase and so
the pancreas releases less insulin.
Protein
is the major component of muscles, tendons, ligaments and bone. Without
protein, blood pressue forces fluid into cells and the body becomes
bloated.
The body cannot survive on a
diet completely void of
fat. Diets must contain some fat, not only for survival but for optimal
health and well being. Fat provides a back
up energy source for the body. If differs from carbohydrate
in that it causes little or no
rise in blood glucose levels so it does not result in insulin release
into the
blood after digestion. Since insulin is the
designated facilitator of fat storage,
low carb diet proponents say a high fat diet that’s also low in
carbohydrate
actually prevents the body from storing glucose as fat Fats
are classified as
either saturated or
unsaturated. Saturated fats tend to be
solid at room temperature. They can be found in meat,
cheese and cream contribute to
clogged arteries and increase your risk for heart attack and stroke. Unsaturated fats tend to be
liquid at room temperature. They can be found in
corn, safflower and other oil and are considered good for your
heart because they lower the
levels of
harmful fats and cholesterol in the blood. Achieving
the right mix of good fats and bad fats is the key to maintaining
balanced nutrition.
Healthy
fat sources include the following:
Acai Berry - this fruit from the Amazon has gained notoriety as the most powerful antioxidant of all the fruits and vegetables we consume today, but it is also a source of healthy fats. The main fat in acai is Omega-9 or oleic acid which is also the primary fat in olive oil. The acai fruit is also a good source of Omega-6 fat and also contains Omega-3.
Olive Oil - the primary source of oleic acid or Omega-9 is extra virgin olive oil which contains powerful antioxidants that help to lower blood pressure, improve cholesterol levels, stop inflammation and protect again cancer and stomach ulcers. The lower the acidity of the olive oil, the higher its antioxidant content.
Chia and Flax - chia and flax help to reverse the imbalance between Omega-3 and Omega-6 fats because they contain higher levels of Omega-3. Flax is the most concentrated source of Omega-3 from plants.
Cocnonut Oil - if you must cook with fat, use a healthy saturated fat such as coconut oil. Sudies have found that people whose diets are high in coconut oil are healthy and trim. Because the oil withstands heat, it is a favorite among wellness oriented individuals. The best coconut oil must be unrefined. Look for virgin, organic products.
Fish Oil - naturally high in EPA and DHA, fish oil is the most concentated source of Omega-3 and fish oil supplements are usually free of mercury or toxins found in fish. Both EPA and DHA work together to reduce inflammation and protect against conditions such as heart disease, diabetes, inflammatory diseases and premature aging. They also help to control appetite, supporting weight loss.
Drink More Tea
Studies
have
shown that people who drink three or more
cups of
tea every day are biologically younger than their actual age by about
five
years. Not only is it relaxing to sit with a cup of tea, but it is also
good for you. The tea plant, a native of Southern China, has been used
for thousands of years as medicine. Women all over the world have
turned to tea to help lose
unwanted pounds.
Some tea contains caffeine which stimulates
the brain and is an effective energizer. Other teas come naturally
decaffeinated. Tea contains antioxidants called polyphenols, but green
tea is believed to contain the most because it is the least processed.
Polyphenols can help lower your cholesterol and blood pressure, protect
against ulcers and strokes, improve digestion, and protect the body
against bacteria and viruses.
Tea revs up metabolism - drinking tea every day helps the body burn up to ten percent more calories according to research conducted at Japan's University of Tokishima School of Medicine. The catechins in tea raise the body's metabolism through a process known as thermogensis.
Tea lowers sugar spikes - the powerful polyphenols found in tea help to balance blood glucose levels, especially after a high carb meal.
Tea blocks the absorption of fat
- the polyphenols in tea also inhibit the activity of the enzyme lipase
according to Japanese research. This blocks the absorption of dietary
fat and cholesterol in the digestive.
