In a five-minute video, a vegan lobbyist presents scientific information regarding the role of proteins in human body, why feeding babies cow milk can be dangerous and how the "Insulinlike GrowthFactor 1" (IGF-1) and the putrefying protein negatively impact our heath.
People eating a plant based diet get 70% more protein than they actually need. Nevertheless, there is still a general concern about protein deficiencies, presumably caused by faulty RDA (Recommended Dietary Allowance) established 100 years ago and by a false correlation between the Kwashiorkor disease and protein deficiency.
