There is nothing wrong with the moderate consumption of meat. In fact, most of us could not imagine living a life without meat. I, for one, will not give up the occasional spicy steak or grilled fish. However, research does show that a vegan diet can help you live longer.
There has been a massive amount of science coming out supporting how a plant-based diet can help you lose weight and improve your wellness. Vegans and vegetarians have significantly lower death rates than those who eat meat.
Veganism is not a new concept and it has been receiving more attention recently. Many people think that a vegan diet is the same as being a vegetarian. The confusion is understandable, but the difference is that vegans have a stricter diet than vegetarians.
Vegetarian diets have been around since 700 B.C. Vegetarians do not consume any poultry, meat, shellfish, game and fish. Their diets contain various levels of vegetables, grains, fruits, nuts, seeds, and pulses. The inclusion of eggs and dairy products depend on the type of diet they follow (1).
The common types of vegetarians include:
Thus, a vegan excludes not only animal flesh, but also eggs, dairy, and other animal-derived ingredients such as honey, gelatin, shellac, albumin, pepsin and whey. They only consume foods strictly from the Earth. When it comes to milk, vegans choose rice, soymilk, or almond. They also use maple syrup instead of honey.
In vegan diet, vegans replace eggs by following recipes that use ingredients like baking soda, vinegar, dairy-free yogurt, and unsweetened applesauce. There is also an egg replacer powder available in the market. A diet without dairy products or any meat is likely to contain less saturated fat, which is associated with higher cholesterol levels.
But where do they get protein? How do vegans acquire enough protein without the consumption of meat and dairy?
One of the biggest debates among vegans and non-vegan dieters is how vegans acquire enough proteins daily while following their strict diet. Most anti-vegans claim that it is almost impossible to get enough proteins. However, there are many protein sources available without having to eat meat.
Vegan athletes like Rich Roll, Jimi Sitko, and Brendan Brazier are proving that plant-based protein can also built strong muscles and help in keeping vegans healthy enough to bike, swim, run, or pump. Vegans get their protein from:
Vegans have lots of protein sources without having to consume meat.
Vegan diet is increasing in popularity nowadays. It is associated with numerous health benefits due to its high content of fiber, folic acid, magnesium, potassium, vitamins C and E, and other phytochemicals and unsaturated fats. Also, vegans tend to be thinner, have lower blood pressure and lower serum cholesterol, lowering the risk of cardiovascular disease (2).
This certainly sounds great as a vegan diet is healthy for the heart. It is low in saturated fats and reduces the risk of heart ailments. However, excluding animal products from your diet also increases the risk of some nutritional deficiencies such as vitamins B12 and D, omega 3 fatty acids, and calcium. In some cases, vegans may also have zinc and iron deficiency.
In a study published in the US National Library of Medicine, the levels of triglyceride, total cholesterol, low density lipoprotein and high density lipoprotein were compared among vegetarians and omnivores (3).
76 men and women were separated into four groups: vegans, omnivores, lacto-vegetarians and lacto-ovo vegetarians. To measure the effects of their diet, their blood samples were taken. It was reported that omnivores have significantly higher levels of triglycerides, low density lipoproteins, and cholesterol. Vegans had decreased levels of these three.
It was also discovered that there was no difference in HDL levels. However, the ratio of HDL to cholesterol was higher in vegans. With these results, people wonder if going vegan can make you live longer and lose weight faster.
In another study also published in the US National Library of Medicine, the relationship between vegetarian diet patterns and mortality has been evaluated. 96, 469 Seventh-day Adventist men and women participated, from which an analytical sample of 73, 308 participants remained (4).
According to the results, weighty associations with vegetarian diets were detected for cardiovascular mortality, renal mortality, endocrine mortality, and noncardiovascular noncancer mortality. This means that vegetarian or vegan diets can reduce the risk of various diseases and premature death. Swapping eggs and meat for nuts and lentils could add years to your life.
Many people choose a vegan diet for different reasons, such as for health, animal ethics, or environment. Some people also try this diet to lose weight. Vegans have lower body mass indexes than omnivores and many studies acknowledge that this strict vegetarian diet can aid weight loss.
In a study of vegan diet compared to a more moderate low-fat diet, 64 overweight women was randomly assigned to a National Cholesterol Education Program or vegan diet for 14 weeks. The study was done in 2 replications and 62 women started the study. In the first replication, 28 women received no follow-up support after 14 weeks. The other 34 women were offered group support meetings for a year (5).
According to the results, women in the vegan group lost more weight than those in the National Cholesterol Education Program group.
Another study from the Arnold School of Public Health observed the effects of a vegan diet as compared to an omnivorous and plant-based diet. Participants were randomly assigned vegan, semi-vegetarian and omnivorous diets. After six months, participants on the vegan diet lost more weight than the other two groups by 4.3% or 16.5 pounds (6).
One of the instant results of embracing a vegan diet is weight loss. It is a positive effect that draws many people to veganism. While there are numerous benefits of this diet, there are also cons that vegans should watch out for.
Practicing a stricter meal means additional effort in getting your everyday dosages of essential vitamins and minerals. While vegans can get protein from nuts, beans, and other vegetables, the recommended amount of protein according to the Centers for Disease Control and Prevention is 46 grams per day for women 19 and above and 56 grams daily for men.
Meat, especially beef and shellfish are the great sources of iron. It is important for vegans to consume foods rich in iron. Lack of this essential mineral can lead to severe fatigue and problems with the nervous system. Men need 8 mg daily between the ages of 19 and 50 while females need 18 mg of iron. Vegans can get iron from white beans, spinach and soybeans. They may also need iron supplements.
In a study of 4,000 participants, they were divided into groups of completely vegetarian and non-vegetarians. According to the results, vegetarians displayed elevated prevalence rates for anxiety, depression, and somatoform disorders (7).
In addition to nutrition deficiency, many vegans find it difficult to stick to their strict diet when traveling. Most countries cater to people who eat animal products and not many restaurants offer vegan choices. Events and parties can also be difficult and vegans may sometimes have to bring their own meals.
Of course, vegetarian and vegan diets are better than fast food diet that general public eat. However, they can also be restrictive.
