A vegan diet is complied of only plant-based foods. This means that it cuts down on animal cruelty, and the deaths of thousands of animals each year. Veganism has multiple nutritional benefits, as well as physical benefits and prevention of diseases.
Veganism can decrease climate change and global warming. Producing meat products adds up to 37% of human caused methane emissions, 9% of human carbon dioxide emissions and 65% of human nitrous oxide emissions. Animal agriculture increases global warming more than transporting that meat does. One kilogram of lamb, including production, cooking and transport, gives of 39.2 kilograms of carbon dioxide. The meat that gives off the least is chicken, but that’s still 7 times more carbon dioxide than meat, coming in at 6.9 kilograms of carbon dioxide.

Drinking and consuming animal products cause you to ingest amino acids and other animal fats, which is one of the leading causes of osteoporosis, also known as brittle bones. Many people believe that drinking milk will fix this, as it contains a large amount of calcium. Unfortunately, because of the amino acids contained in it, milk does not do its job as well as we’d like. The body converts these amino acids into sulphate, which causes the bones to deteriorate and the bone to dissolve into the bloodstream. Calcium in milk is only approximately 32% absorbed into the body, but for vegetables such as kale and brussel sprouts (ew, I know) the calcium absorption rate goes up to between 40 and 64%.
In 2016, a study was carried out that gave figures saying cancer rates have gone by 45% in cancer caused by excess weight over the past two decades. A plant-based diet reduces growth of the IGF-1 hormone. This hormone promotes the growth of cancer cells. This means that people on a vegan diet, particularly women, have less chance of female-specific cancers, such as breast, ovarian and cervical cancers. This means that many forms of cancer can be prevented and even slowed for easier treatment by following a vegan diet.
Studies that date back to even the 1920’s show that people who follow a mainly plant based diet, so vegetarians and vegans, have a lower blood pressure than people who eat meat. A plant based diet causes weight loss, lower cholestrol and controls blood sugar. This means that hypertension is treated. Approximately 62,000 people die from hypertension related illnesses, including heart attacks, which could be prevented by lowering blood pressure. Because of this, veganism can also prevent type-2 diabetes, as it controls blood sugar, as I mentioned earlier.
