Protein is a part of almost all foods we eat, legumes, meats, eggs, and even fruits and vegetables. The thing is, not all proteins are created equal; they differ in quantity, quality and digestibility too. Protein is the basic building block of the human body, we need it to repair muscle, bones, and skin, and to produce enzymes and hormones. That’s why we should choose protein sources carefully. Let’s look at some popular food groups and see how they compare.
So, this is how it usually goes: We get infected with harmful bacteria, and if our immune system can’t handle it on its own, we use antibiotics. They kill off the unwanted intruders along with some of our good symbiotic bacteria. It’s not ideal, but a small price to pay when it’s a life and death situation. Overall it’s a pretty good system. Now, imagine a different scenario in which some bacteria become immune to our antibiotics. We would effectively go back at least 100 years in our medical history, before penicillin was invented in 1928. We would have no way of treating bacterial infections. Considering how fast bacteria can spread thanks to our modern ways of transportation, it could be a worldwide threat to billions. Sounds pretty scary, right? Well, it gets worse! Those kinds of bacteria already exist and we, as a human race, are hard at work to produce a lot more of them. Why? And what can we do to stop it?

Vegans don’t eat animals; insects are animals; vegans, therefore, don’t eat insects. Simple, right? But wait. Did you know that insects don’t feel pain and cannot suffer? Did you know that insects provide all the nutrients that are hard to get on a vegan diet? Did you know that insects require less feed, less land, and less water than any other animal by far? Did you know that substituting some plants for insects can actually reduce animal suffering? No? Then it’s time you took a closer look, because insects are the best thing that happened to veganism.
We are all well aware of the inhumane treatment and killing of animals that goes on in slaughterhouses and concentrated animal farming operations. But there is another much less talked about, but just as real danger to animals: Farming of edible crops.
Even in a well-formulated real foods vegan diet there are many possible, even unavoidable, nutrient deficiencies. Several studies have shown that both vegetarians and vegans are prone to deficiencies in B12, calcium, iron, zinc, omega-3 long-chain fatty acids EPA & DHA, and fat-soluble vitamins like A & D. Let’s go through the most common ones and look for a solution that doesn’t involve pills, injections or fortified foods.
