This is such a silly website. It’s run by a Christian organization that’s trying to prove that vegetarian/vegan diets are deficient in essential nutrients (even though the scientific community has agreed that vegetarianism/veganism is a healthy diet option). It’s disappointing that bias such as this exists, but the website’s exaggerations are pretty funny. “Customers in a health food store who are vegetarians can easily be identified. They simply look malnourished. Muscle tone is poor. The arms on women and children look like sticks with skin, but the biggest giveaway is the skin tone. They are a ghostly gray. One glance at them reveals they are iron deficient.” Haha.
