whey protein – Healthy superfoods – by Dr. Nuwanthi Fernando


What is Whey Protein?

Naturally, milk is composed of two types of proteins- whey and casein. Their composition varies from different milk types. For instance, breast milk is made up of 60 % whey and 40 % casein. Cow’s milk, on the other hand, is made up of 20 % why and a whopping 80 % casein. The greater the whey protein percent in milk, the easier it is digested in the gut. Whey protein is a complete type of protein because it contains all the essential amino acids which cannot be manufactured by the body. Whey is also low in lactose, a compound that many people react to in milk.

Whey is a Superfood

Whey is a superfood because it is loaded with nutrients such as amino acids, vitamin D, omega 3 fatty acids, and antioxidants. Its bioavailability is so high that makes it easy to be absorbed and utilized in the body. The whey protein is completely packaged with nutrition that ensures a proper building, rebuilding, repair, and rejuvenation of the body. Whey is, therefore, a superior protein source in the diet that provides an above average nutrition. The high levels of vitamins, phytonutrients, and minerals offer tremendous health benefits.

Whey is Excellent for Muscle Building

Ideally, the muscle mass of an individual is expected to decrease with advancing age. This leads to a compensatory increase in the fat content of the body. High-fat content is responsible for many diseases including diabetes, and cardiovascular diseases. Whey protein can prevent and slow down the unwanted change in the composition of the body fat and muscle proportions. Only high-quality sources of proteins can help effectively build the lean muscle mass. Leucine, an anabolic or bodybuilding amino acid is found in greater amounts in whey proteins than in most other sources of proteins.

Whey is a Potent Antioxidant

The body is full of oxidants that come from metabolic processes which release free radicals. These substances have the potential of causing so much damage to the body that the body is expected to bind them safely. The antioxidant that is most significant in the human body is known as glutathione. While this antioxidant is manufactured in the body, it relies on the supply of amino acids that can be limited by many factors. Whey protein is high in cysteine amino acid which promotes the manufacture of glutathione. Whey protein ensures that the body gets enough antioxidants which will reduce the oxidative stress levels.

Whey is an Antibiotic

Whey boosts the immunity and helps the immune system to fight off pathogens. Whey protein also has direct effects on fungi, viruses, and bacteria. Lactoferrin is responsible for the antibiotic properties of the whey protein. It makes the growth and survival of the micro-organisms difficult so that they cannot spread and affect a larger area of the body. Whey helps to contain the infection from organisms such as Candida species, Escherichia Coli, and some Salmonella species. This goes a long way in preventing the occurrence of cancers.

Whey is Heart Healthy

Whey proteins have lactokinins which are angiotensin-converting enzyme inhibitors. They help to lower the blood pressure in people with hypertension. Reducing an abnormally high blood pressure prevents the onset of many heart diseases. Whey proteins also lead to a better health of the heart because they can reduce the low-density lipoproteins otherwise known as the bad cholesterol. This reduces the risk of heart diseases and other adverse cardiovascular events like stroke by as much as 8 %.

Whey for Weight Loss

The whey protein reduces hunger as it is satiating. When the individual feels full, they won’t have to eat frequently and they decrease the total calories in the body. This forms the greatest secret in losing weight. Whey protein also works in many other ways to decrease the body weight. This includes boosting the metabolism so as to ensure that the individual burns more calories even at rest. All these health benefits and special properties make whey proteins very necessary in the diet.
