America has become one of the top ten most overweight countries in the entire world. As America grows and grows, so does its people. However, some of the population has the desire to turn this around and slim down. Losing weight, if an individual is already obese, is a very difficult journey to accomplish. This is especially true if somebody would like to lose a substantial amount of weight. For this reason, Americans have turned to any other alternative or supplement to speed up this process and reduce the amount of effort it takes for the pounds to come off. This includes …show more content…
Key supplements that are void in a vegan diet include vitamin B12, vitamin D, and iodine. Most vital of the three, vitamin B12 is a key energy reserve in the human body. This vitamin helps with regulated functioning of the brain and the formation of red blood cells. This is important to address due to the fact that "68% of vegetarians and 83% of vegans are B12 deficient, compared to just 5% of omnivores" (Herrmann W1, Schorr H, Obeid R, Geisel J.). Ultimately, most vegans and vegetarians are not receiving as much of this vitamin as they should. As a result, vitamin B12 deficiencies have the potential to cause hardened arteries, memory loss, and learning problems. If a lack of nutrient continues, homocysteine can occur, which produces blood clots and increased oxidative stress. If this is an issue, vegans can just choose to take a daily vitamin B12 supplement, right? Well, if this is such a healthy diet, then why are supplements needed to maintain a healthy lifestyle? Although this could be an option, it is only valid to an extent. Synthetic forms of vitamins and minerals are no match against a natural source. This is due to the studies of micronutrients. The research and knowledge on micronutrients is limited, but "studies regarding the benefits of omega-3 supplementation are inconsistent, but research on …show more content…
This idea has been spread since "1971 with the publication of the surprise best-seller Diet for a Small Planet" (Whoriskey). The reason for this is because a "dietary pattern that is higher in plant-based foods... is associated with lesser environmental impact than is the current average U.S. diet" (Dietary Guidelines Advisory Committee). Instead, this has proven to be wrong. Research conducted by Carnegie Mellon University has proven that adopting a vegetarian diet will "increase energy use by 38 percent, water use by ten percent and greenhouse gas emissions by six percent" (Whoriskey). A food comparison between pork and lettuce resulted that "on a per calorie basis, producing lettuce creates nearly as much greenhouse gas emissions as does beef" (Whoriskey). This research has proven the exact opposite of what vegetarians had originally stated. Sticking to a vegetarian diet will produce green house emissions at a much higher rate than an omnivorous

    Some examples of dieting may include a plant-based diet and fad diets. Individuals continuously strive to take part in the trend of dieting due to the positive results that follow; however, they do not recognize the negative impacts of each diet. There are many challenges that follow each specific diet. For example, the challenges of a vegetarian diet are to have enough protein and vitamin B in one 's diet as well as to not consume a multitude of processed food, carbs and sugars (Anisman-Reiner). '"The most dramatic change to the diet is being vegan rather than the raw element, because you are cutting out two huge food groups.…

    You may by wondering if there is a correlation between health diseases and eating habits. Research clearly reveals that there is, indeed, a lower chance for a vegetarian to develop a disease than a non vegetarian. Studies by Claude Chang and Beyme Frentzel showed “vegetarians were about 40% less likely to develop cancer compared to meat eaters”. Likewise a Harvard study “showed that daily meat eaters have approximately three times the colon cancer risk compared to those who rarely eat meat” which runs parallel to M.D. Michael Greger’s opinion that is ”I think the most interesting finding in the new Harvard studies is that…they still found increased mortality risk”.…

    Converting vegetarianism, a person who consumes a plant-based diet, isn’t as rewarding as it seems. Many people have tried to prove that vegetarian diets are far more healthier than omnivore diets, any animal that is a generalist feeder, consuming a wide variety of that that can include both animal and plant matter (Freedman). According to the article“Sorry, Vegetarians. A New Study Says Eating Green Won't Lower Your Risk of Early Death,” by Sharon Kirkey, studies have shown that a vegetarian diet does not prolong someone’s life. Although vegetarian diets are cheaper, an omnivore diet can be just as healthy and have a similar environmental effect as a vegetarian diet.…

    Neal Barnard suggests that “in clinical trials in individuals with type 2 diabetes, low-fat vegan diets improve glycemic control to a greater extent than conventional diabetes diets” (Barnard 255). This means that if you limit your intake of sugary foods and increase your intake of vegetables and foods with lots of fiber, then you will be in better health. Barnard also emphasizes the importance of considering veganism when he says “diabetes prevalence is lower among vegans compared to omnivores” (Barnard 256). Non-vegans are more prone to getting a chronic disease such as diabetes and cardiovascular diseases than vegans. In accordance with Barnard, Lenka Belinova argues that “the intake of meat, particularly processed meat, is a dietary risk factor for diabetes” (Belinova).…
