 Living vegan. A large no on the plates. Meet Lisa. When she goes food shopping, she often sees the word vegan. She thinks about her student friends who demand more vegan dishes for their canteen. Lisa is curious. What does vegan actually mean? Vegan is a form of the vegetarian lifestyle. Vegans do not only disapprove meat and fish, but relinquish all animal products. Besides, they also avoid leather clothes or even animal shows at a circus. But especially flexible or part-time vegan is very popular. Tom still eats his uncle's honey. And Johnny sometimes buys second-hand leather products at the flea market. But why is this movement so popular, especially in industrialized countries? There are various reasons. Set off, for example, by scandals and news reports. More and more people inform themselves about the way and the consequences of how animals are kept and how meat is produced. The facts often do not match the expectations. Some people go vegan when they find out more about the production of eggs and milk, where each animal is exploited to get the maximum output. Disgusted, they look for alternatives. Why do we eat animal products anyway? Because of the ingredients. Meat, milk, eggs, and fish have always been around in tough times to satisfy humans' nutritional needs and give them more variety in their diet. Flat-based food is always available today. The permanently high consume of meat entails a health risk. So vegans are often even healthier than people would expect. A reason for medicine to take a closer look. A study of Belgian and French universities shows when it comes to the quality of the ingredients, vegans are in first place. But vegans should pay special attention to certain substances. For example, vitamin B12 is not present in sufficient amounts in almost any plant-based foods. That's one case where nutritional supplements are helpful. These days, more and more vegetarian and vegan dishes are served in restaurants. And in nearly every supermarket, you can find a meat substitute. But of course, a vegan sticker doesn't automatically make everything healthy. Lisa has to inform herself. She sums up. If people inform themselves on the keeping of animals and the consequences, they decide to eat fully or partly vegan. But it stays a personal choice. Lisa wants to eat less meat now and pay more attention to her choice of food. And with that, take care of the environment. By eating less meat and more fruits and vegetables, she even saves money. That way, she can afford selected food and can help organize the market.
