High cholesterol is when a person has too much of a fatty substance called cholesterol in their blood. Too much cholesterol blocks blood vessels making it more likely to have a heart attack or stroke. Having high cholesterol is mainly due to a diet of fatty food, not exercising enough, being overweight, smoking and drinking alcohol. A person can lower their cholesterol by taking certain supplements and adding more whey protein to your diet could help lower your levels.

What is whey protein

Medical News Today explained: “Milk is made of two proteins, casein and whey.

“Whey protein can be separated from the casein in milk or formed as a by-product of cheese making.

“Whey protein is considered a complete protein as it contains all nine essential amino acids.

“There are many benefits associated with the consumption of whey protein, and researchers are constantly finding new possible therapeutic properties.”

Whey protein is among the best studied supplements in the world, and for good reason.

Whey protein has a very high nutritional value and scientific studies have revealed numerous health benefits it contains.

Studies indicate that long-term, high-dose whey protein supplementation may help to lower one’s cholesterol levels.

In a study with the National Library of Medicine, the chronic effects of whey proteins on blood pressure, vascular function and inflammatory markers in overweight individuals was investigated.

The study noted: “Whey proteins may reduce blood pressure and improve cardiovascular health.

“This study evaluated the effects of whey protein supplementation on blood pressure, vascular function and inflammatory markers compared to casein and glucose supplementation in overweight individuals.”

The study involved the individuals to consume 54 grams of whey protein per day for a period of 12-weeks.

By the end of the study it was noted a significant reduction in total and LDL cholesterol.

Different types of whey protein

Medical News Today said: “There are three primary types of whey protein which include whey protein concentrate, whey protein isolate and whey protein hydrolysate.

“Whey protein concentrate contains low levels of fat and low levels of carbohydrates.

“Whey protein isolates are further processed to remove all the fat and lactose.

“Whey protein hydrolysate is considered to be the pre-digested form of whey protein as it has already undergone partial hydrolysis which is a process for the body to absorb protein.”

Different types of protein shakes affect cholesterol in different ways, but studies show that whey protein and soy protein both lower cholesterol levels, optimise their particle size and reduce the risk of heart disease and metabolic syndrome.

There are also other benefits of whey protein shakes including helping with weight loss and lowering blood pressure reading.

It’s important to speak with your GP before embarking on any new supplements to help with high cholesterol.
