The Difference Between Whey and Casein Protein

One of the single most important supplements any athlete or active person should consider consuming is a high quality protein source. Ideally this comes from natural, organic foods like chicken or turkey or beef. But there are many other types of protein (dairy, soy, pea, etc.) that you can choose from as well if you are finding it difficult to cook so much meat all the time. I tend to prefer the dairy proteins whey and casein, as I think they are more palatable. Whey and casein are milk proteins that have been studied and researched extensively over the past few decades. They are simply a byproduct of the cheese and curd manufacturing process and their benefits are many:

  • Whey: A popular post-workout protein drink that is purported to provide antimicrobial activity, immune modulation, improved muscle strength and body composition, and to prevent cardiovascular disease and osteoporosis [1]. Whey protein is the perfect post workout meal because it is a fast absorbing protein, which will give your muscles the protein it needs when they are most hungry, and it is chock full of amino acids. Whey proteins have all the essential amino acids and in higher concentrations compared to other protein sources. Furthermore, the amino acids found in whey are efficiently absorbed and utilized by the body. In addition to the essential amino acids in whey protein, it has high concentrations of Branched Chain Amino Acids (BCAAs). BCAAs such as leucine, isoleucine, and valine, are important in the tissue growth and repair process [1]. And because whey protein is rich in sulfur-containing amino acids, the immune system is enhanced through intracellular conversion to glutathione. I’ll spare the super nitty gritty details of all the biological processes and just get to the point - hydrolysis (aka degradation and digestion of the protein) of whey in the small intestine allows for the greater absorption. Another positive effect of whey protein is it’s anti-tumor and anticarcinogenic potential from the available glutathione that detoxify potential carcinogens.
  • Casein: A slow digesting protein due to it’s coagulation under the acidic conditions found in the stomach which slows the entrance into the intestines. Due to slow digestion relative to whey protein, it is generally a good protein to drink at night before you go to bed. That way, your muscles will be fed with high-quality protein and nutrients throughout the night when you sleep.

Protein powders are often useful if you need a high quality protein source in a hurry. Or if you are on a calorie-restricted diet, they can provide a large quantity of protein (which will help keep you feeling full) for a small amount of calories.



6 Benefits of Staying Hydrated That Most People Don’t Know About

There are dozens of benefits that come from drinking plenty of water. Here are the top six:

  1. Backaches. The back of our body rests on the spinal cord. The spinal disk core is made up of a large volume of water and dehydration, which leads to back pain in many individuals.
  2. Improved athletic performance. Since muscle is about 80% water, it’s important to keep your muscles fueled with what it needs. Even slight dehydration can lead to altered body temperature and increase fatigue. Furthermore, during exercise, your body will sweat in an attempt to keep your core temperature low. This can lead to even more dehydration. It’s a vicious cycle
  3. Smoother bowel movements. If you tend to have difficulty pooping, it could be caused by lack of sufficient water intake
  4. Weight loss. Yep! Drinking more water can help you lose weight as it can increase satiety and boost your metabolism.
  5. pH Balance. The human body maintains a pH range of 7.35-7.45 for proper physiological processes. An acidic shift may lead to sickness and an inability of the body to assimilate vitamins and minerals.
  6. Prevents Cardiovascular Disease. In order to maintain the proper viscosity of blood, plasma, and fibrinogen, it is important to drink adequate water to make sure the blood is moving through the pipes properly!

So how much water is enough water? There are a handful of online calculators out there like this one and this one but the general rules are:

  • If you are a sedentary person (low-activity job with little to no exercise) - ~64oz of water each day
  • If you are a moderately active person (low activity job with medium to intense levels of exercise for 30-60 minutes a day, 4-5 days a week) - ~100-150oz of water each day.
  • If you are a very active person (high activity jobs with high intensity exercise for 30-60 minutes a day, 4-5 days a week) - ~120-170oz

Everyone’s body is different so these numbers might not be the most precise for you. Looking at the color of your pee is a good gauge as well. If your pee is more yellow/dark yellow, you need to drink more water. If your pee is a light/very light yellow, you should be good.

What Are Supplements and Should I Take Them?

We aim to shed some light on what dietary supplements are, the benefits they could provide, and some things to consider when thinking to add a supplement into your routine. What we are not aiming to do is to tell you that you should go out and buy all of these and start taking them all the time. What you put into your body depends on what your goals are and what you need. For the most part, you will see the most dramatic improvements to your health and physical performance by eating nutritious­ foods. And if you want to add in supplements to your routine, add them in one at a time so you can see the affects of each. In that way, you will be able to better judge whether it is the right thing for you.

The word “supplements” can often provoke a negative connotation and, for some people, their mind goes straight to steroids. However, supplements are different than steroids because steroids (specifically anabolic steroids) are drugs that directly affect the nucleus of cells to alter testosterone content in the body. The results of taking steroids typically include increased muscle mass, increased strength, hepatotoxicity, immune dysfunction, glucose interolerance, in addition to a myriad of other psychiatric, cardiovascular, and musculoskeletal effects. Supplements, on the other hand, are vitamins and powders of ingredients that can normally be found in the food that we consume or naturally in our bodies. Examples include, but are not limited to, Vitamin C, protein powders, Fish Oils, multivitamin pills, etc.

Whether or not you do choose to add in a supplement, I would recommend researching it as much as you can to evaluate for yourself the benefits. Supplements will definitely not cure any diseases, but they could help you with getting the right nutrients you need. If you do choose to take a supplement, it is important to drink plenty of water. In fact, drinking plenty of water is SUPER important regardless of whether you are taking supplements or not (maybe we should write another blog about water intake….). Water allows your liver, kidneys, brain, stomach, etc. to function properly and helps these organs efficiently process any supplement you are taking. In addition, water helps flush out the body and remove waste products generated when performing high intensity exercises. And just like the bottle might say “consult your physician if you have questions on if this is the right thing for you”.
