Nutrient Availability in Plant Versus Animal Sources
"From my Low Carb USA presentation "Plants vs Animals: Bring It On!" These are the micro-nutrients that often come into question in this debate. Note that every single one can be found in animal foods--sometimes in much smaller amounts--(although organ meats often rich sources)-- but always in the correct form and always highly bio-available. Also worth noting that high-sugar diets increase our demand for many of these nutrients, making our perceived requirement higher than would otherwise be the case. Note that plant foods are completely lacking several essential nutrients--not just B12. When it comes to micronutrients, animal foods are clearly superior to plant foods. " Georgia Ede.
