All of this talk about grass-fed could not be complete without including B12, which is grass-fed meat and its side components like dairy and organs are rich in. B12 is a water-soluble vitamin. What does B12 do?
- Required for red blood cell formation. Without it cells would be oversized and poorly shaped, making them function wrong (a condition referred to as pernicious anemia).
- Neurological function. Needed for the formation of the myelin sheath that surrounds cells and is important for among other things, cell communication.
- DNA synthesis
- Helps metabolize proteins, carbs and fats. Protein especially depends on proper cycling of B12, and amino acids can become unavailable without it.
There are some recommendations for adequate and top-notch B12 absorption. For starters, B12 is unique in that it is dependent upon intrinsic factor (protein produced in the stomach) for absorption (like in the case of pernicious anemia, it is often caused by a lack of intrinsic factor, rather than B12). Also important for proper absorption is B6 (spinach, bell peppers, turnip greens, garlic, cabbage, celery, cauliflower, asparagus, mushrooms, broccoli, chard, and kale). Vitamin E (turnip greens, mustard greens, chard, almonds, spinach, collard greens, kale, bell peppers, Brussels sprouts, tomato, blueberries, and broccoli) is needed to take B12 from its non-active phase into an active one. Good sources of B12?
- Excellent sources: snapper and calf’s liver
- Very Good: venison, shrimp, scallops, salmon and beef
Clearly eating red meat and organs (which we’ll look at more tomorrow) are great ways to get B12. For ultimate absorption eat with some great vegetables like spinach, peppers, turnip greens, mushrooms, cauliflower, broccoli, asparagus, or Brussels sprouts (which also happen to be thermogenic) for more absorption as they’re rich in B6 and vitamin E.
