R20, did you work in the Trump WH? Because you just can't get your facts straight.
1. "Cholesterol deficiencies" are not a thing. No, really!
2. "The prevalence of patients with vitamin D deficiency is highest in the elderly, obese patients, nursing home residents, and hospitalized patients. The prevalence of vitamin D deficiency was 35% higher in obese subjects irrespective of latitude and age." This is from a medical study on vitamin D deficiency. Many non vegan Americans are vitamin D deficient. You can simply take a supplement.
3. Potassium is obtained by eating: Fruits, such as apricots, bananas, kiwi, oranges, and pineapples, vegetables, such as leafy greens, carrots, potatoes, lean meats, whole grains, beans and nuts.
4. Iron: Since vegans consume non-heme iron, they have to increase the AMOUNT of iron containing foods to ensure that they are not deficient. Again, if you are eating a balanced diet, this is not an issue. Never had low iron in my entire life.
5: People at risk for zinc deficiency are mostly breastfeeding infants, older adults, and alcoholics. Vegan zinc sources are beans, chickpeas, lentils, tofu, walnuts, cashew nuts, chia seeds, ground linseed, hemp seeds, pumpkin seeds, wholemeal bread and quinoa.
In summary, your misinformation is tiresome. I can't tell you how many times I have had to listen to a fat and unhealthy person tell me all about the dangers of my diet, the nutrients that I am lacking, and that veganism will kill me. When you look at the science and the data behind the same lame arguments that people make against veganism, it is simply not true. Eat what you want, but stop spreading unsubstantiated bullshit.
