The Science Behind Veganism
The concept of veganism is often quite frightening to people. After all, that means giving up meat, dairy, eggs, and all products that contain those ingredients. Initially, it seems like such a transition would be impossible, especially if you have been eating these foods all your life. But if you are reading this article, it means you are considering a change and want to see what the benefits of a vegan lifestyle are. Thankfully, most people who start to move away from animal products say it was a lot easier than they thought, especially since so many vegan alternatives to animal foods exist. After all, we are well into the 21st century, and technology has given way to some truly phenomenal, organic, delicious substitutes. Best of all, even without those subsitutes a vegan lifestyle can still be very easy.
So what exactly do you gain by going vegan? If you are going to "give up" so much, there better be a payoff. When it comes to diet, there is no better nutritional return on investment than veganism. First, it instantly cuts out a huge amount of saturated fat, animal protein, cholesterol, preservatives, and toxins from your diet. Nearly all animal products are high in these things, especially processed and packaged meats. These are almost always doused in sodium nitrite, a preservative linked to cancer in both adults and children, although the risks seem to be even greater for children's developing bodies. Furthermore, studies have shown that high saturated fat diets cause heart disease, through the accumulation of fatty cholesterol pockets in the arteries.
Even the protein in animal products is problematic, and that's the main benefit that animal products are touted for providing. For one, anything made from an animal is harder to digest than a plant, so the bioavailability of the protein is less than it might otherwise be. In addition, because of the high quantity of animal products that people consume, it is easy to experience protein toxicity. This forms from the ingestion of high amounts of sulfur-containing amino acids like methionine, and such toxicity (in the form of higher blood acidity) hurts all parts of the body and can increase the risk of several diseases. Ironically, to combat the acidity created through diet, the body leeches calcium from the bones to neutralize it. This is why studies have shown that increased milk consumption, with the supposed benefit of making bones stronger from the calcium, doesn't actually protect bones and can actually hurt them. The best sources of all nutrients are from plants.
The best evidence for the success vegans experience is the scientific studies surrounding them. Vegans who eat properly have much lower rates of death from any cause, more energy, better attitude, and often an overall glow. Of course, it is possible to have an unhealthy vegan diet, as there are vegans who subsist largely on white flours, sugar, soy, and little fruits or vegetables. For veganism to have a truly magnificent effect on health, you must ensure enough calories are still absorbed through nuts, seeds, fruits, vegetables, legumes, and whole grains. It's easy to do this as long as you pay some attention to meeting those requirements, and soon enough you will be enjoying veganism so much you'll wonder why you didn't switch sooner.
