How much nutrition? The main one, PROTEIN. Plant protein is what is called an "incomplete protein" because plants do not contain the total amount of essential amino acids that our body needs. However, ANIMAL protein does. Animal protein is a complete protein. Second, cholesterol. Cholesterol is so important for the body that the liver makes it when it is deficient in the diet.
I repeat again, THERE IS NO WAY. THERE IS NO SCIENTIFIC WAY that the body can synthesize sex hormones without cholesterol. NO WAY. This is like saying that instead of drinking water, from now on I am just gonna take deep breaths. Bullshit. YOU NEED water to survive. True, not eating cholesterol is not gonna kill you because your liver WILL make it, however an unhealthy liver WILL NOT produce enough cholesterol. It is scientifically proven that since the introduction of fat free diets and cholesterol free diets, diseases like erectile dysfunction, dementia, alzheimer, panic attacks, bipolar disorders, etc skyrocketed like never before. The parallel the introduction of these mythological diets which by the way, it is completely proven today that cholesterol has absolutely nothing to do with heart disease for example. That was a myth.
