NUTRIENTS
This page is dedicated to
bringing you some basic information about Carbohydrates, Protein, Fat,
Fiber and Vitamins. I hope with this information you will have a better
understanding of what you are eating or putting into your body. I think
the key to eating is understanding what you eat because then you can make your
own decisions about what is healthy. It is hard to go on a diet when
people just tell you what to eat, but you really don't know why you are eating
or omitting it. By understanding the nutrients you eat you will be able to
understand and read food labels which will also help determine how honest the
company is being with you.
There are 6 Major classes of Nutrients: Carbs, Protein, Fat, Fiber, Vitamins &
Minerals. Water, although not a nutrient, is another substance you don't
want to omit!!!
Carbohydrates are both the primary and preferred energy source for all
body functions and physical activity. They are especially good for high intense
or anaerobic activity. They are not the "bad guys" they are made out
to be if eaten "properly". By properly, I mean eating complex carbohydrates such
as whole grains and avoiding most simple carbohydrates such as candy.
Some simple Carbs such as fruit and vegetables are good for you.
Carbohydrates feed you energy in the form of sugar, but the complexity of them
is how fast or slow they fuel you. "Simple" carbs give you a quick boost of
energy, but soon you drop and get tired. They are more useful immediately
before a short lasting high intensity activity or after your activity.
"Complex" carbs slowly release the sugar so it gives you a more steady
stream of fuel, ideal for a diabetic. They are useful an hour or so
before competition, especially before a long event. Complex Carbs contain starch
& fiber. All starchy foods are derived from plants. (In fact most all
carbs, except those found in milk, come from plant sources). A favorite of the
fitness competitor is the Sweet Potato...just don't had the fat and sugar to it
with butter and sugar.
Not only do carbs help fuel your body; they also are essential to fuel your
brain and central nervous system! You may have noticed on a low carb diet
that you are tired can not think clearly. This is a sign that you need to make a
change. Carbohydrates also help the body to use it's fat storage more
efficiently!
Why do carbs get a bad reputation?
Carbs get a bad rep because people love sugar and too much sugar causes weight
gain. Guess what though, too much of anything causes weight gain. Carbs are
often comfort foods so we eat them during holidays, winter, downtimes or in
celebration. It is easy to eat them in excess and it's harder to get children to
eat the good ones, i.e. vegetables! Soft drinks and fruit juices are also
loaded with sugar. Opt for diet soft drinks and fruit juices made with 100%
Fruit, not ones with added sugar. Stay away if the first ingredient is High
Fructose Corn Syrup! Restaurants serve rolls throughout dinner and Southerners
love their bread! Often low-fat foods are high in sugars (carbs) so people load
up on them and still gain weight. Eat only whole-wheat breads and limit yourself
to one roll.
* ingredients ending in: "ose" are a form of sugar. (Lactose, Fructose,
Sucrose, Maltose, Glucose etc...)
* Except for the Sugar Substitute Sucralose (Brand name Splenda). It was
originally derived from sugar.
Fiber
is actually a form of carbohydrate. It differs from simple carbohydrates and
starches b/c the sugar units are held together when consumed. Since the sugar is
not released, the fiber does not serve as a functional source of energy.
However, it does play a role in weight loss. Most people think of fiber as
"bulk" or "roughage" . This is because instead of breaking down in your body,
dietary fiber typically passes through carrying other nutrients and enzymes with
it. When you eat most fibers such as vegetables they absorb water and swell
causing you to feel fuller faster and longer. This in itself can help aid in
weight maintenance or reduction b/c you may not eat as much or too soon after.
More importantly though, fiber works in your intestine to soften the contents
helping with elimination. Fiber is especially important to men and anyone
at risk for colon cancer. It may bind to cancer causing materials and
eliminate them out of your system more quickly. Fiber is also known to help ward
of heart disease. It may lower LDL cholesterol (the bad one...think HDL-"h" for
Healthy). Although Fiber helps prevent disease, cancer and constipation,
more is not better. The general recommendations are 27-40g/day. Most people do
not meet the current standard so too much may not be of concern, but note that
too much fiber can pull too much water out of your body leading to dehydration.
It may also pull important minerals such as calcium out before they could be
absorbed. It may be recommended to eat meals with important minerals
separately from those with fiber. Popular sources of Fiber are: Vegetables,
Oats, Brown Rice, Whole Grains, Flax and Fruit.
*** If you do not currently consume Fiber, add it SLOWLY into your diet. Too
much at once and your friends may not want to stand too close!
Protein
is the favorite muscle building nutrient in the fitness industry. It is
the worker that builds & repairs your body tissue, not confined to the muscle.
It also helps repair tendons & ligaments you may have injured during activity.
So why do people go on low carb diets if carbs are the preferred energy source?
Protein can be an energy source, but only when you are consuming too little
carbohydrates, fat or overall calories. But, if the protein is being used for
fuel it will not be as efficient at it's primary job, to build muscle and
synthesize hormones and enzymes. If you are eating more protein than you
need, the protein will turn to fat. Fair, no, but that's what happens. If you
are not working out with weights and trying to build muscle, your body doesn't
require the extra protein that is being marketed today. The typical person only
needs .8 to 1g per Kg bodyweight. If you lift weights you may want up to 1.7g/kg
bw. The quality of protein also varies. It can come from both plant and animal
sources, but the majority comes from animals. The best source of protein is the
egg. Other proteins are rated based upon albumin, i.e. egg white. Other
favorites are whey, grilled chicken, lean steak, fish, ostrich and buffalo.
***As with Fiber, slowly add protein to your diet.
Fat is essential to our body. It not only is the primary storage
form of fuel, but it also pads and protects our vital organs and without
it, fat soluble vitamins A,D,E,K would have no place to go but out of your
body. Fat also provides the fuel for light aerobic exercise and long
endurance activities. If you were stranded in a snowstorm, your body
would feed on your fat to help keep you from dying of starvation. It is very
important to understand what is good fat and what is bad. Basically Saturated
Fat is bad. Unsaturated Fats (polyunsaturated &
monounsaturated) are good for you. One of the biggest sources of
Saturated Fat comes from Coconut Oil. Another to watch out for is Palm Kernel
oil. Unfortunately, the vast majority of the huge selection of protein
bars sold today contain one of these oils. Good fats may come from Canola
Oil, Olive Oil and Flax. They are also found in fish in the form of Omega Fatty
acids. I recommend eating fish for you Omega FA's instead of getting it in Fish
Oil Pills. Salmon (baked, smoked or grilled) is a great source!
Why is fat bad? The bad fats such as the saturated fats raise your bad LDL
Cholesterol and lower your good HDL cholesterol. They stick to your arteries and
contribute to the number one killer in America, Heart Disease. If you are
diabetic, you have a 50% greater chance of getting Heart Disease, so you must be
conscientious of bad foods.
Did you know there are fats that aren't directly listed on the label?
These are the Hydrogenated Fats. The process of hydrogenation ruins the
unsaturated fats by making them more saturated. This is done to prolong the
shelf life of items with oils in them. If the item sat on the shelf without
certain ingredients being put through hydrogenation it would quickly perish and
go rancid. This process can also cause Trans-Fats to form. Trans-Fats are
thought to be as bad as saturated fats because they can raise your LDL and lower
your HDL. They lower the stuff that is good for you! The worst of it all
is that the food label doesn't list these fats directly under the fat listing.
You must look under the ingredients for "hydrogenated or partially hydrogenated
x-oils". You can also add up the numbers under the fat listing.
For example: Total fat is: 12g Saturated: 1
Monounsaturated: 3 Polyunsaturated: 4
The fats only total 8, but the Total says 12. This means there are probably
4grams of hydrogenated fat so stay away!
Many new items now market themselves with something that says "No hydrogenated
Oils" or "No Trans-Fat"
Vitamins: A, D, E, K (Fat Soluble)
These vitamins are stored in your fat so they stick around in your body longer
and you could overdose on them.
Vitamin D is necessary for Calcium Absorption!!!
Vitamins: C & B complex (Water Soluble)
It is unnecessary to load up on these vitamins because excess will just be
flushed out of your system.
Minerals:
Macro: Calcium, Sodium Chloride, Potassium, Magnesium, Sulfur and Phosphorus
Trace: Copper, Fluorine, Iron, Zinc, Selenium, Chromium, Iodine, Cobalt,
Manganese, Molybdenum, Silicon, Vanadium, Nickel, Tin, Cadmium
Although they all play an importance I stress getting enough of the Macro
Mineral Calcium! This mineral is extremely important in young women
because they are in the stages of building their bones. Without it they will
have brittle bones or risk having Osteoporosis as an adult. If taking a calcium
supplement, look for one that includes Vitamin D as it is necessary for the
absorption of Calcium. A great one is Caltrate with D. Calcium also helps with
the fat burning process.
Water, though not a
Nutrient, is essential to
life! Drink lots of it :)
How to read a
Label:
Each gram of x Nutrient as so many kilocalories per gram of that nutrient. If
you multiply the number of grams of the nutrient by the number of calories it
provides per gram it will give you the total number of calories that nutrient
contributes to the food item
Fat: 9 kilocalories/gram
Carbohydrates (and fiber): 4 kilocalories/gram
Protein: 4 kilocalories/gram
Alcohol: 7kc/g (though metabolized like a fat)
Example) Pizza Sauce:
**Serving size 1/4 Cup
| Total Calories: 30 |
Total Calories (before): 30 |
| Total Fat: 1g (unsaturated) | Total Fat: 1g x 9kc = 9 |
| Total Carb: 4g | Total Carb: 4g x 4kc = 16 |
| Protein: 1g | Protein: 1g x 4kc = 4 |
| Total Calories (after) 29 |
*Although it is 1 calorie off, this is quite accurate. It could be off slightly
because the real fat total may be 1.1 giving the item an extra calorie.
**Always
look at the serving size! Often the serving size in a bowl of cereal is 1/2 Cup.
Who eats that! Most people fill a big bowl to the top. Also look closely at a
20ounce bottled drink. Usually it holds 2 1/2 servings per container! This means
instead of thinking it only has 40 sugars, it really has 100 sugars! Wow! No
wonder our population is heavy. Everything is "Super Sized"! Please see my page
on Rules to Eating for serving size
examples!
Don't forget to add up the unsaturated fats and saturated fats to check for
hidden hydrogenated Fats!
When reading wheat product labels don't fall for the bag saying "WHOLE WHEAT".
If the first ingredient isn't whole wheat neither is the item! Often they read
enriched wheat flour or unbleached wheat flour. Most of the ingredients have
taken out all the stuff that is good for you! Buy bread products when the first
ingredient reads "Whole Wheat Flour" or "Stone Ground Whole Wheat Flour" or
"Organic Whole Wheat Flour". Whole What products typically have more fiber. Some
enriched products have fiber added so they may be ok as well.
Some to try: Pepperidge Farm 9 Grain Bread, Hodgsons whole wheat products, Kashi
Heart to Heart Cereal, Kashi TLC Crackers
Visit a local health food store if you can't find any at a typical grocery
store.
