Wow . . . Macronutrients! Fancy word huh? All it means is that we need a lot (macro) of those nutrients. Sure vitamins and minerals are also important, and of course water, but without the "Macros" (protein/carbs/fats) our bodies would be in BIG (pardon the pun) trouble.
Macronutrients play a big part in almost everything that has to do with our body. They are so important that they are always referenced to with any type of diet (<--- bad word) and/or meal planning. You will constantly see Macronutrient Ratios with percentage numbers as a guideline for your meal planning. It will look like this: 45/30/25. Meaning 45% protein, 30% carbs and 25% fats. Most of the time it will be in the order of protein/carbs/fat but sometimes the carbs and fats are switched. Always make sure the of the order when you are following the ratios! Basically these ratios are used to make sure you get the proper amount of the macronurtients on a daily basis. There are various thoughts and opinions on what the ratio(s) should be, and that will need to be another post!
See . . . I'm getting side tracked already. Let's get back to the topic:
* BTW: This is just a basic outline for some general knowledge. There is far more detailed info about all three that can be acquired with a little research
Protein(s) are chains of amino acids and play a very important part in our body. It is the main component of our hair and nails. Protein also is used to build and repair tissue, along with making enzymes, hormones and other body chemicals. Protein is an important building block for bones, muscle, skin and blood. The human body cannot synthesis protein nor can it store any surplus. So this means we must acquire our individual amount (everyone is different) through the food and supplements we take daily. As you can guess, protein is very important and needs to be at the top of our shopping list.
Now that we know what protein is (my very simplest explanation), where can we find it? Well just about everywhere. Meat, fish, nuts, dairy, eggs and even some vegetables have protein. All at different levels and sometimes at the cost of having to accept the extras that are included, such as fat, carbs and lactose!
Okay, we know that our bodies need protein and we can get it by eating the various foods above. So all good right? Yes and no. First, you need to know how much protein your body needs on a daily basis. On average, a person will need 0.5-1.5 grams of protein per pound of lean body weight, depending on their level of activity. For some people this can be a challenge because of all the food they would have to eat. Who has time for that nowadays anyway! To make things a little easier you can obtain protein as a supplement in the form of a powder to mix into a drink. Some of the popular ones use either, whey, casein, soy and egg as the main protein source.
On to carbohydrates. What was once the main focus for fuel for our body has now become a main source of controversy. Let's face it . . . carbs at their basic structure are just sugar molecules. How good can that be? For our body, it is the desired source of fuel. In general there are 2 types of carbohydrates: simple and complex. Simple carbs like fruit and table sugar, are broken down fast by the body, while complex carbs ( carbohydrates that have 3 or more linked sugar molecules) take longer to break down and are absorbed more slowly into our system. The reason for this is because our bodies breakdown carbohydrates into individual sugars before they can be absorbed. So, the more sugars a carb has the longer it takes to break down. This is then mostly converted into glucose, commonly refered to as blood sugar. A certain amount of glucose can be stored in our liver for future needs. The amount of glucose in our blood system is regulated by the hormone insulin. Here is where the problem starts. Our bodies need a certain amount of blood sugar to function properly. Unforunately too little or too much glucose along with the challenges of regulating it can cause a whole lot of problems such as Hypo/hyper-glycemia and diabetes.
So, when you think about carbohydrates, also consider what type of carb your eating and why. Carbs like bread and pasta may be great if you are a triathlete in training, because your body will be in need of lots of quick fuel to off set those hard-core workouts. But, those are "empty" calories with no substantial nutritional value. A better choice for your daily carbohydrate intake would be vegetables and a moderate amount of fruit. They are full of other healthy nutrients that the body needs!
Finally fats, my favorite macronutrient. I can't get enough of the good fats, and I'm not scared of 'em! Fat used to be a bad word. Old conventional wisdom taught us that fat is bad. Well I'll argue that one. Of course not all fats are created equal, and it is the "good" fats that I am in support of.
Ask what types of fat are there and you will hear words like saturated, monounsaturated, polyunsaturated and trans fatty acids. Yikes! When put that way none of them sound good, and some are a lot worse than others. But you really need to know the difference. I could do my best to explain them all in detail but there is some chemistry involved and well, I just do not like chemistry! So, I highly recommend for you to read a great article by Mark Sisson:
The Definitive Guide to Fats
Now let me tell you why I like "good" fats, (formerly called) Saturated Fats. Now you will learn all the health facts by reading Mark's article. What I want to add is that saturated fats helped me loose 25 pounds! No I didn't just sit on the couch watching TV and eating butter, cheese and marbled steak all day. Although that sounds absolutely delicious! I also worked out and changed my meal planning to a healthier lifestyle. What made the difference is that I eliminated all grain carbs from my diet, and replaced them with more (good) saturated fats. Yup, no bread, pasta or other nutrient empty carbohydrates. This caused my metabolism to look for another source of fuel to burn, and guess what that was? Yes again . . . FAT! My body uses my fat (well any that still is remaining) along with the fat I eat as fuel. How cool is that? I know, I know, not all of you will be totally on board with this concept, but remember . . . there was a time that everyone thought the world was flat!
Before you go out and buy all the butter off the store shelf here is my disclaimer: You need to cut your carbohydrate intake way back for this to work. Otherwise your body will use the carbs as fuel and store the fat as . . . yup, fat.
Now I know this post was supposed to be about macronutrients and I hope my simple explanations helped some of you. I just couldn't resist added a little "fat" on the end . . .
