Grass Fed Why Protein Buyers Guide

It’s important to remember that we all need to get enough protein each day.

However, as we get older especially after the age of 40 we slowly start losing lean muscle mass and may need even more protein g/kg body weight.

If you are worried about eating too much protein then listen to Dr Shawn Baker who eats an all meat diet or carnivore diet.

Also listen to Prof. Stuart Phillips who is a protein researcher who shared tips on how much protein we all need everyday, especially on a keto or low carb diet.

What is Grass-Fed Whey Protein?

Grass-fed whey protein is made from the milk of 100% grass-fed cows. Cows that are grass-fed roam free in pastures for either all or part of their lives, rather than being kept in small, crowded enclosures.

Since the cows are fed on their natural diet of grass rather than grain, grass-fed whey protein is believed to be healthier and more nutritious than other whey proteins.

Grass-fed whey protein also tends to be free of hormones, GMOs, and pesticides. (ref)

Benefits of Organic/Grass-Fed Whey Protein

Here are some direct benefits of grass-fed protein:

• Contains Omega-3 fatty acids, which are have anti-inflammatory properties
• Preserves immunoglobulins, which boost the immune system (ref)
• Stimulates muscle growth and recovery
• Helps manage diabetes by having a positive impact on blood sugar
• Assists in weight loss by suppressing the urge to overeat (ref)

Although not all grass-fed cows are organically raised, they are not limited to confined animal feeding operations (CAFOs).

CAFOs are overcrowded, disease-ridden facilities that businesses use to achieve maximum efficiency in animal breeding, butchering and production. They are widely considered to be inhumane and cruel for the animals inside them. They are also thought to produce lower-quality animal products that are full of hormones, antibiotics, GMOs, and other potentially harmful substances. (ref)

USDA Certified Organic dairy producers are required to give their cows access to open pastures, compose their diet of organic feed and at least 30% grass, and treat them humanely while allowing them to express natural behaviors.

Not all grass-fed whey is certified organic, but using grass-fed rather than conventional protein powders guarantees that the cows are getting at least some access to their natural diet. (ref)
