Lean white meat is deficient in nutrients… chicken breast is not adequate.
However, carnivore includes real high nutrient density sources specifically from fats and organ meats. Liver is a phytonutrient and mineral smorgasbord- it’s my version of broccoli. Red meat is full of essential amino acid and animal fat is an amazing source of fat soluble vitamins. Bone marrow and bone broth are also dense. Eggs are amazingly balanced and nutrient full. Fish are also excellent sources of vitamins and minerals. I love my sautéed cod liver.
There are no deficiencies in a balanced carnivore diet. There are no issues with constipation either - only plants do that if we remove their fiber. Eating plants actually forces us to eat other plants because they consume vitamins to be digested. Vitamin C being the most impactful. Eating meats does not deplete vitamin C, so we don’t need to eat citrus to fix it… no scurvy for real carnivores.
We are basically made of meat and fat and eating animals gives us what we need. The only cohesive argument I’ve heard against life long carnivore was made by Dr Rhonda Patrick on the Joe Rogan show, where she was concerned that the gut bacteria could bias towards amino acid fermentation vs fiber fermentation. The byproduct of this AO fermentation could cause inflammation and colon cancer over long term use. My read is that this is a function of eating too much protein and not enough fat and organs… I believe that a balanced carnivore diet fixes these risks.
Tallow, liver and organs, eggs, bone marrow, fish, clams, oysters, shrimp, roe, fat, red and white meats… it’s all part of a healthy balanced carnivore diet to me.
