A Summary of Macronutrients

By: William Moore

        Macronutrients are chemical substances that are needed by the body in relative amounts in order to maintain the body’s normal growth and development.  The three types of macronutrients are carbohydrates (simple and complex), fats (saturated and unsaturated) and proteins (constructed from various amino acids).  Carbohydrates (carbs) are the body’s most preferred source of energy since they are the easiest of the macronutrients to metabolize.  Simple carbs are digested quickly and are usually made up of refined (machine processed) sugars that have been stripped of most of their vitamins and minerals.  Examples of simple sugar sources are juices, soda, candy, and white bread.  Complex carbs take longer to digest and are usually good sources of fiber, vitamins and minerals.  Examples include vegetables, whole grain, cereals, breads, and pasta.  The bulk of our carbs consumed should be complex.

Fats, although digested very slow and metabolized for energy relatively slow, contain the highest amount of energy per gram in relation to the other macronutrients (9 Kcal/g in fat to the 4 Kcal/g in carbohydrates and protein).  Fats also play several roles in the body such as protection of organs, thermal insulation, and aiding in the absorption and production of certain vitamins among other things.  Of the two types of dietary fat (among the several other types of fat in the body), saturated fats (sat. fats) are difficult to oxidize (breakdown) and, in excess, is linked to higher rates of cardiovascular disease.  Sources of sat. fat are dairy products, certain animal meats and certain processed foods among several.  Unsaturated fats are a bit easier to oxidize and are less toxic within the body but they also provide somewhat less energy than its saturated counterpart because of its unsaturation.  Sources include avocadoes, nuts, vegetable oils and olive oils.

Proteins are chemical compounds of various amino acids that the body requires to grow and function.  Proteins can even be used as energy in certain circumstances.  Of the 22 amino acids, 9 are essential (cannot be synthesized in the body and must come from dietary sources) and the rest are nonessential (synthesized in adequate amounts in the body).  Sources of protein are eggs, meat, fish, and milk.  Protein also comes in different qualities whereas some of the sources don’t contain complete proteins (proteins with complete amino acid profiles i.e. some aminos are missing).  The best quality proteins are eggs, whey, and meat.  Incomplete, poor quality proteins come from plant sources.  However, incomplete proteins can be mixed to yield complete proteins (i.e. rice and beans).

8 Common Myths of Diet

Taking Vitamin C prevents colds. With all due respect to the late Linus Pauling and
his widely publicized theory on the relationship between vitamin C and the cold virus,
research on the subject has not found that taking vitamin C helps to ward off those
unwanted sniffles. On the other hand, studies have shown that vitamin C may (in some
instances) slightly shorten the duration of a cold.

Consuming more protein builds bigger muscles. Ingesting additional protein (in
whatever form – meat, pills, powder, etc) will not help most individuals develop larger
muscles. Your protein daily requirement is based on your body weight. Most individuals
meet their needs through food alone. If you eat more protein than what your body needs
on any given day, most of the excess will be converted to and stored as fat. As such,
exceeding the recommended daily allowance for protein can be, at best, a waste of time
and money.

2% milk is 98% fat free. Not surprisingly, food marketers – in an effort to encourage you
to buy their products – often engage in advertising that is misleading. For example, a
food label may proclaim that a particular foodstuff is fat free to a specific percentage. In
the case of 2% milk, the number refers to the relative weight of the fat in the product, a
factor that is inconsequential and misleading. In reality, what you really want to know
with regard to the fat content of milk is the percentage of fat calories in the milk itself.
A cup of 2% milk for example contains 35% fat calories (42.5 calories of the total 120
calories).

Eating low fat foods will not cause you to gain weight. Keep in mind that the labels “fat
free” and “low fat” do not mean no calories. For example, non fat and low fat foods
could easily be full of sugar and high calories. Controlling your body weight is a by
product of maintaining the appropriate balance between the number of calories you ingest
and the number of calories that your body uses. Excessive calorie intake, regardless of
whether it comes from “healthy” non fat or low fat foods, will promote weight gain.

If consuming some of a particular nutrient of food is considered healthy, eating more
of that foodstuff will provide even greater benefits. Your body needs a specific amount
of nutrients (carbs, fat, protein, vitamins, minerals and water) to function properly.
Exceeding that level will not give you an extra “boost”. In fact, ingesting too much of
some nutrients can be potentially harmful.

Antioxidants can help prevent types of cancer and heart disease. Eating foods that
are relatively rich in antioxidants (e.g., beta carotene and vitamin C and E) or taking
antioxidant supplements has not been found to prevent either cancer and heart disease
– despite numerous studies that have investigated the matter. To date, no conclusive
evidence exists that shows that antioxidants lower the risk of either medical condition.

Foodstuffs that are labeled “natural” or “herbal” are always good for you. Foods can
be “natural” or “herbal” and still have negative health consequences. Neither term is a synonym for harmless or non – addictive nor guarantees that a particular food contains the essential nutrients your body needs. In fact the opposite may true. Cocaine and nicotine,
for example, are also naturally occurring plant by-products.

Healthy eating represents the end of appetizing meals. Eating in a sensible healthy
manner does not have to be an exercise where you force yourself to consume poor-tasting
food at the expense of mouthwatering delectable alternatives. What it does involve,
however, is determining what foods are good for you and learning how to prepare them
to “delight” your taste buds. It also entails making good eating habits an integral part of
your daily living,

7 Pillars of Nutrition, 7 Sins

Posted: August 23, 2011 by Bizzy Amor in Nutrition

7 Pillars of Nutrition

  1. Prepare meals in advance
  2. Eat about every 3 hours (stoke the fire and let your body know its ok to burn calories)
  3. Do not eat to get full, if you get stuffed you’ve eaten to much
  4. Eat a lean protein with each meal (15 to 20g a meal for women)(20 to 30g for men based on size)
  5. Eat natural unprocessed foods (not from a box) ex: apples over apple juice
  6. Do not drink your calories (except green tea)
  7. One cheat meal per WEEK (no cheat days, in one cheat day you can gain more fat than you’ve lost all week)

7 sins

  1. White bread, rice, potato
  2. Sweets
  3. Fried food
  4. Fast food
  5. Sodas
  6. Alcohol
  7. Mayo
