Fuel The Fighter: Top Protein Myths Exposed

Every serious MMA athlete knows that protein is an essential part of a fighter's diet. The amino acids that make up proteins are involved in building and maintaining strong bones, muscles, tendons and ligaments. Endurance athletes regularly weight training should aim for up to.77grams of protein per lb of body weight [1]. Hydration with lots of water is also a vital part of processing higher protein intake. Keep your body in peak condition by choosing the right amount of protein and by weeding out nutrition fiction that circulates around the gym.
    Weight (lbs) Daily Protein Needs (g)
    135 105
    145 113
    155 120
    165 128
    175 136

    195 152
    205 159

Myth #1

Raw eggs are a great protein source

In addition to the risk of food poisoning, long-term ingestion of raw egg whites increases the risk of becoming deficient in biotin, an important nutrient. Biotin can become bound to avidin, which is found in raw egg whites. Simply cooking eggs thoroughly will allow the body to benefit from the protein found in eggs without the risks [2].

Myth #2

Animal protein is always best

While it's true that animal protein like meat, milk and eggs are complete protein sources and are a bit easier to digest than plant protein [1], it's important to have a balance between these the two. Some studies have shown that diets mainly consisting of animal protein can cause a significant increase in blood acidity. In response to this, stored calcium from the bones leaks out into circulating blood to act as a buffer. Make sure to include plant protein to help keep bones at their sturdiest. [3]

Myth #3

Soy is the best form of plant protein

Excessive soy intake can actually slow down protein digestion by interfering with important enzymes. Soy has the ability to halt production of thyroid hormones that oversee many aspects of metabolism. Soy products may also interfere with hormones in the body since they contain phytoestrogens, which mimic the human hormone estrogen. No need to give up soy, just be sure to balance soy foods with other plant proteins [3].

Myth #4

The more protein I eat the better for my endurance and recovery

More isn't always better! Since the body has no way to store the nitrogen found in proteins, it must be processed and excreted in urine. Processing large amounts of protein puts added stress on the liver and kidneys. Also, eating a diet with unusually high amounts of protein will result in greater calcium loss in urine. This is not the ideal situation to maintain optimal bone status [2].

Myth # 5

It doesn't matter when I eat protein so long as I get enough.

Making the time to include high quality protein as soon as possible after a workout will definitely pay off. This is exactly the time when the body needs the protein, since the post exercise period is when repairs start to take place. As part of this repair process, existing bodily protein can be burned to help rebuild. By making the effort to give your body fresh protein to work with, muscles will be able to grow [5].
