>2.3. Misleading food comparisons Plant-to-animal food comparisons are deceiving because animals provide many actually useful by-products[1] that are needed for medicine, crop fertilization, clothing, pet food and public water safety[2]. Vegans are in general very dishonest when comparing foods, as seen here[3] where they compare 1kg of beef (2600 kcal, 260g protein) to 1kg of tomatoes (180 kcal, 9g protein). The claim that we could feed more people just with more calories is also wrong because the leading causes of malnutrition[4] are deficiencies of Iron, Zinc, Folate, Iodine and Vitamin A - which are common and most bioavailable in animal products.
