The whey protein is a derivative of milk and cheese (which is often referred to as the gold standard of proteins), which since 420 BC was promoted for their health benefits.
At that time, Hippocrates advised his patients whey. Currently, the whey protein is linked to health benefits such as:
- Support your immune system because it contains immunoglobulins
- Help preserve lean body tissue (especially during exercise), providing bioavailable and cysteine amino acids
- Keep blood pressure levels which are already within the normal range, and promote healthy vascular function 1
The whey protein promotes weight loss and muscle development
In addition to providing all the essential amino acids the body needs, the whey protein of high quality that comes from cows raised with organic pasture, also contains three ingredients of particular importance for health: leucine, glutathione and conjugated linoleic acid (CLA ).
Both leucine as the CLA may be useful if you try to lose weight while glutathione stimulates your overall health by protecting your cells and mitochondria from peroxidative and oxidative damage.
Although many recommend to whey protein as a way to increase your protein intake, I would be cautious in pursuing a high protein diet to lose weight.
It is true that protein helps reduce hunger by making you feel full longer, and by affecting certain hormones (increase the amount of certain hormones that reduce appetite while decreasing levels of ghrelin, the hunger hormone).
In addition, the protein can give a boost to your metabolism, and a number of studies suggest that high protein diet causes increased weight loss. 2 , 3
But there is compelling evidence suggesting that too much protein could stimulate the development of cancer by activating the mechanism of the target of rapamycin in mammals (mTOR, its acronym in English).
Beware High-Protein Food
Rarely if ever do, studies comparing diet high in protein / high carbohydrate / low fat with which it is high in fat / low carb / with a moderate protein content. If they did, we could have clearer this topic. For example, a study in April compared the following power:
- 15% protein, 35% fat and 50% carbohydrate
- 30% protein, 20% fat and 50% carbohydrate
They found that the protein group lost 30% 8.1 pounds (3.7 kg) obtained more than 15% of their calories from protein. However, do both types of power are far from ideal in terms of proportion of nutrients! Both are excessively high in carbohydrates and very low in fat.
Later I will talk about the needs of proteins, but for now suffice it to say that while your body needs protein, and whey protein is an ideal supplement training to promote development and muscle repair, it is important track your protein intake from all sources, and not be exceeded .
An amount of 30% protein is three times what your body needs for optimal health. So whether you try to achieve weight loss or meet your overall health and longevity, avoid food that is high in protein.
Instead, focus on increasing the level of healthy fats and eliminate net carbs (no fiber), while maintaining a balanced and moderate protein intake, calculated according to your body composition, which immediately explain.
Leucine-forming agent A Powerful Muscles
Consider these three ingredients that make the whey protein is such an attractive addition to your fitness and diet, and started with leucine . While played many roles in the body, leucine signals the mTOR mechanism to increase protein synthesis, and thus promotes muscle growth.
However, you really need very high amounts of leucine for optimal effect; much more than the recommended daily allowance (RDA, for its acronym in English), because most of leucine is used as a building block rather than a powerful anabolic stimulus.
The whey protein is ideal because it contains much more amount of leucine than other foods.
Only 3 ounces whey high quality containing about 8 grams leucine. To get that amount of other foods, would have to eat 1.5 pounds of chicken, more than 1 pound of almonds (more than 3,000 calories!) Or 16 raw eggs.
Glutathione helps other antioxidants to Serve at its highest level
Also, protein whey is an excellent source of precursors of glutathione , which is the most potent antioxidant of his body. This "master antioxidant" is a tripeptide which is within every body cell. As you probably already know, antioxidants are crucial to eliminate harmful free radicals from your body.
Most free radicals are produced during the metabolic process, but may also result from exposure to toxins, radiation and heavy metals. Since free radicals are so destructive, cells have a defense network designed to neutralize them.
This network consists of antioxidant vitamins, minerals and special chemicals called thiols (glutathione and alpha-lipoic acid). Glutathione is different from other antioxidants because it is intracellular .
Has the unique ability to maximize the activity of all other antioxidants, including vitamins C and E, CoQ10, alpha lipoic acid and antioxidants found in fruits and vegetables (hopefully) come every day .
Glutathione is important for energy production and Mitochondrial Function
Glutathione is also an essential factor in the use of energy, detoxification and prevention of diseases we associate with aging, largely by stimulating a healthy mitochondrial function. Deficiency is linked to:
- related to age, such as Alzheimer's and Parkinson's diseases
- coronary and autoimmune diseases
- Arthritis, asthma and other inflammatory diseases
- Cancer
- muscle weakness and fatigue
Dependent glutathione synthesis of adenosine triphosphate (ATP, for its acronym in English), so that when ATP levels are low, also have lower levels of glutathione.
This is another reason why exercise is so beneficial to your health - among other things, it increases ATP levels and glutathione. And to improve domestic production of glutathione, also strengthens your immune system.
The whey protein increases the production of Glutathione
Although glutathione can be found in supplement form, foods like whey are the best alternative.
The quality whey provides all essential amino acids for the production of glutathione (cysteine, glycine and glutamate) and contains a single cysteine residue (glutamylcysteine) which is highly bioactive in its affinity to become glutathione.
Also, the whey provides critical cofactors, immunoglobulins, lactoferrin and alpha-lactalbumin (this is also a great source of cysteine), which together help create the optimal metabolic environment for high activity of glutathione.
Most oral glutathione supplements have shown to be poorly absorbed. Worse, glutathione supplements may actually interfere with your own body's production of glutathione.
Your body is programmed to produce itself glutathione, and taking a synthetic supplement your body decreases its own production, which will become dependent on an external source.
Another alternative is to take a supplement of alpha lipoic acid, which can help regenerate glutathione (also alpha lipoic acid helps regenerate vitamins C and E, which remain active in the body longer).
The red and organ meat are the best food source of alpha lipoic acid. In addition, vitamin D can help increase intracellular glutathione levels.
Some authorities nutritionists recommend taking a form of cysteine known as N-acetylcysteine (NAC, by its acronym in English), but I would not advise using this supplement if you still have amalgam fillings mercury because it could interfere with detoxification mercury.
