Which Whey is Best for You?

Image Which Whey is Best for You?

Whey protein has long been considered the benchmark for athletes to use as it is so highly bioavailable. In addition, it is unsurpassed at building/maintaining muscle mass. This is due partly to its high biological value (usability) as well as its high level of branched-chain amino acids (BCAAs) that are primary fuel for muscles. For many years, when protein powders were consumed primarily by athletes or body-builders, these attributes were well-known and appreciated. Protein powders today are not only much more widely available but are in demand by a much broader demographic than just athletes. We will discuss the benefits and uses of whey protein as well the different options available.

What is Whey Anyway?

Miss Muffet

There are two main proteins in milk: casein and whey. Simply put, casein is the solid protein, or curds, and whey is the liquid protein and amino acid components extracted during the cheese making process. Despite the source, there is very little lactose or casein in regular whey products so people with these allergies/sensitivities generally are able to tolerate whey protein products.

Concentrate vs Isolate

There may be some confusion over the difference between these two types of whey protein. In a nutshell, whey isolate contains more protein per gram (and serving) than a concentrate. Generally isolates contain about 90-96% protein content. In contrast, concentrates are 12-20% lower in protein content, containing 25-89% protein. A typical isolate, for instance, contains about 24 grams per serving, being the high end. There is one more major difference between the two however, and that we will explore below.

Whey Chalkboard

Whey Concentrate's Compounds

The processing to make an isolate for its higher protein levels removes a large range of micronutrients, some of which possess great value. This makes a quality whey protein concentrate a valuable, medicinal food. In addition to conjugated linoleic acid (CLA), a beneficial fatty acid involved in healthy metabolism, it will contain compounds which benefit immune function, intestinal health and more. Whey is high in the amino acid cysteine, which raises levels of the antioxidant glutathione. This amino acid is vital to immune and lung health. It is particularly important for liver detoxification also, helping to excrete heavy metals and other harmful compounds. Certain portions of whey are prebiotics, influencing the growth of healthy intestinal bacteria. Lactoferrin present does this as well as its role in regulating iron absorption. Immunoglobulins present are involved in passive immunity, antimicrobial activity in the gut and also neurotransmitter production (serotonin).

Additional Health Benefits

Whey Muscles

As a result of its superb nitrogen retention, whey protein may facilitate muscle growth and prevent muscle breakdown, making it useful for not only athletes but people with (muscle) wasting conditions. In particular, it may help prevent the sarcopenia (muscle atrophy) which occurs in aging. Whey's ability to promote glutathione synthesis may help eye conditions such as cataracts and macular degeneration, as these conditions are hastened by poor antioxidant status in the eye. The glutathione-boosting properties helping the liver may prevent cirrhosis and improve liver function in hepatitis B patients. Respiratory health depends on adequate glutathione production in the lungs and thus whey protein may help alleviate COPD symptoms as well as asthma. Finally, whey's immunoglobulins have been shown to enhance antibody and neutrophil production and may therefore help to prevent various bacterial and viral diseases.
