Did
you ever notice a thin layer of liquid at the top of yogurt whenever you open
the yogurt container? Surprisingly, some people discard the top layer into the
trash, but this top nutrient enriched watery layer is a valuable part, since it
hold all the health benefits and known as WHEY, a fast acting and quickly
absorb-able complete protein that contains all the nine essential amino acids.
Industrially whey protein powder is categorized into various
forms, based upon the protein, fat, carbohydrates and lactose content. The
amount of proteins, fat and lactose depend on the filtration methods as the
whey protein concentrate (up to 80% protein) is lightly filtered in contrast to
whey protein isolate (up to 90% protein) which is heavily filtered to remove
lactose, making it less fat-free and retaining more quantity of proteins, thus
isolate form is more refined, have extra amount of proteins and minimum amount
of lactose and fat compared to whey concentrate.
Now
the question is which whey protein form to prefer, whey concentrate or whey
isolate?
Well, It simply depends on health priorities and fitness goals
as whey concentrate is slower to digest than whey isolate for that reason it is
the best choice to keep hunger away. Surely it will help you to feel full for
longer time, support overall health, maintain healthy weight and to meet your
weight loss goal easily.
Another great feature of whey concentrate compared to an isolate
is low price, but contains high level of lactose, which can make you bloated
after consuming or you may have lactose intolerance if you are sensitive to the
lactose. However, whey protein concentrate is the best option for food and
baking industry.
On the other hand whey protein isolate is the best choice for
the intensive form of physical activity, hard training athletes and maximizing
muscle mass because whey protein isolate is easy to break down, absorb quickly
and equally good for the lactose intolerant people, no more gas and bloating as
it carries almost no lactose and also the preferred form for the baby food or
infant formula because of its easy digestible and quick absorbing quality.
