Milk protein isolate
What is it:
Milk protein isolate is a high-protein ingredient derived from milk, particularly the proteins casein and whey. To produce milk protein isolate, skim milk is first subjected to processes like ultrafiltration, microfiltration, or ion exchange to separate the proteins from the remaining components like fat and lactose. These methods filter and concentrate the proteins, resulting in a product with a high protein content (typically over 90%). The isolate is then dried to produce a powder that is low in fat and lactose, and is used in many products including including protein supplements, sports nutrition products, and protein-rich packaged foods.
Rating:
Milk protein has been associated with many health benefits, including preserving muscle mass, increasing bone density, and supplying a beneficial ratio of amino acids for many essential functions of the body. However, people with allergies to casein or lactose intolerance may want to avoid milk protein isolate. While dairy products have controversially been implicated in causing inflammation in some research, other research demonstrates that it may either not impact inflammation or may even help reduce it. However, milk protein isolate used in packaged foods is unlikely to come from organic sources unless specified, and non-organic dairy production is harmful to the environment, the cows, and can negatively impact dairy quality.

How we rate ingredients
Health is like a bank account, certain ingredients make a deposit into your health bank, meaning they add to
your health. Certain ingredients withdraw from your health bank. We want health promoting ingredients in our diet. To keep things simple, we rate ingredients on a green, yellow, red scale:
Clean
It is naturally occurring in food and has no harmful effects on the body. It is real food. It is health promoting.
Caution
It goes into one or more of the below categories
- It is not naturally occurring in food but doesn’t have data showing it has a harmful effect on the body (additives like Gellan Gum)
- It is naturally occurring but can have some harmful effects on the body (added sugars, oils, gums etc.)
We Avoid
It is known to have a harmful effect on the body (ex. All food colorings, Natural Flavors, MSG, Potassium bromate, aspartame, artificial flavors)
