Dear Fiora, I appreciate you taking the time to make a comparison between Kale and Beef. Your final conclusion makes it sound like Kale and other plant life doesn’t contain protein. Anyone who’s ever watched Star Trek knows that we are protein based life forms, so are plants, bacteria, and anything else with a cell wall and or organelles. As a percentage of body weight the best body builder in the world couldn’t put on weight at the proportionate speed of a newborn infant. Yet in nature’s wisdom mother’s breast milk only contains 4.5% of calories from protein. Beef contains 14 times that amount, way too much! Kale on the other hand contains 45% of calories from protein and has all the essential amino acids. Beef contains animal protein which causes protein-induced hypercalciuria, in other words, breaking down all that excessive protein creates a ton of excess acid which is pro-inflamatory. Our bodies will leach calcium, highly alkaline, from our bones to neutralize some and I emphasize only some of the damage. This bone loss can be measured by the unusually high calcium content in the urine of meat eaters and their weak porous bones (that’s where the saying big-boned comes from). Moreover, if you start feeding a meat eater a highly alkaline (RAW) plant based diet, the calcium loss is virtually eliminated. Then you go on to suggest that no plant food contains vitamin B12 and that beef is an excellent source. Both statements are dead wrong. First off, B12 is a bacterium, it is neither a plant nor an animal, but can live with either. Since it is a bacterium cooking will kill this probiotic. So unless you plan on exposing yourself to sewer like bacterial, viral, and fungal sludge aka a raw beef dinner, you won’t be getting any B12 in beef either. Ironically, all of our nutritional food content studies are done prior to cooking (or irradiating), which makes all the sense in the world for safe and healthy plant foods, but this unfairly suggests a nutrient content in animal foods that is for all practical matters, unattainable. By the time a food is heated to 155 degrees Fahrenheit, half the proteins are denatured. In other words, if you want to eat a lot of mutated and therefore carcinogenic proteins beef is what should pass for dinner. If you want to eat alkalizing high protein plant foods then kale, other dark leafy greens, sea vegetables, nuts, and seeds will do a far better job. Lastly, as B12 is a bacterium plants grown organically and eaten raw do, repeat, DO contain vitamin B12. In either case, unless you personally source your plant food from your organic garden or the wild, a B12 supplement is strongly advised.
Do we have a natural meet eating capacity? Yes and no. If you had no other food source, you know were doing something painfully foolish like living in the arctic, then you should definitely eat meat, because that’s what is abundantly available. For the rest of us who have food choices at the supermarket, farmers market, even the gas station, there are plants. Ketosis is the body’s natural adaptation to starvation, one’s appetite is suppressed and proteins which are normally used to build things are rather broken down to create inefficient energy. If animal foods matched our nutritional needs entering ketosis on a meat based diet would be impossible, but rather it’s inevitable. In other words, you can eat all the meat you want and your body will still think it’s starving and enter a starvation state, because the only time a homosapien naturally eats meat, is when it’s starving and possibly digesting itself. So if you’d like to avoid the halitosis, long-term liver and kidney damage, massive buildup of cholesterol and toxins, reduced mental clarity, fatigue and lowered energy, maybe not eating animals is a good idea.
Kale contains more vitamins and minerals than beef. Unlike beef it contains no cholesterol (like all plants) and has phytochemicals (cancer fighting nutrients). In fact, the prefix “phyto” literally means plants. Higher rates of animal food consumption are positively associated with higher rates of cancer, heart disease, osteoporosis, and diabetes. Beef contains more pesticides, heavy metals, pharmaceuticals, hormones, antibiotics, and industrial toxins. Kale is by any reasonable measure remarkably more nutritious! Perhaps, Dr. Joel Furhman’s shirt should have read, “Beef was never Kale” and not “Kale is the new beef”.
