Vegetarianism until now has always been considered to be a way of choice. Rough data suggests that there could be 1.5 Billion people who don’t eat any form of meat. So most people in the world are vegetarians and they can’t help it. A study, Genetics of vegetarianism: A genome-wide association study shows it might be all about our genes.
The study’s “results support a role for genetics in choosing a vegetarian diet and open the door to future studies aimed at further elucidating the physiologic pathways involved in vegetarianism.” Until now being vegetarian could be related to multiple causes such as consideration for animal life, health restrictions, religious afflictions, and sometimes to help control the natural resources from being used up indiscriminately.
The latest study however finds similarities between genes NPC1 and RMC in all vegetarians. So the study opines, “Our findings add to the existing body of data pointing to the genetic contribution to dietary choices and raise the possibility that lipid metabolism and its role in brain function may play a role in the ability to subsist long-term on a strict vegetarian diet.” So is being vegetarian good?
Multiple studies have variant thoughts about the implications of vegetarianism. According to Harvard Health, being vegetarian could be beneficial in more ways than one would think. In a worldwide study conducted with a large pool of samples, they found that 25% of vegetarians seemed to be in the clear of having a cardiac event. Other cohort studies also showed similar results and therefore the scientists believe that it could mean something.
Next researchers have also found that eating certain vegetable and fruits are great to prevent cancers. The studies still need to be verified for credibility. On the other hand, there is ample evidence that also supports the idea that pure vegetarians may not be as healthy as they think they are. Though red meat eaters are known to be susceptible to cancers, fish eaters could be the game changers.
The idea of nonvegetarians being protected against carcinogens is related to the fact they don’t ingest many variables. Animals process the food on their own and sometimes eating them could manipulate the way the cancer particles enter our body. Type-2 Diabetes couldn’t thrive in patients when they were purely vegetarians but the red meat eaters found themselves to be having irregular sugar levels.
Studies that support nonvegetarianism are also not scarce. In fact, scientists believe that non-vegetarians have a lower chance of developing mental disorders like schizophrenia. This is due to the fact that they consume more proteins than vegetarians and this can be a deciding factor. Moreover, meat eaters are known to shed weight easily considering the role of proteins in increasing metabolic activity and developing muscle mass.
Defining the limitations of the study, the researchers believe that they only included, “ female, older, healthier, and of better socioeconomic status than the general population.” Ethnicity was also not taken into account which could alter the results in a major way.
The study also takes vegetarianism as a genetic consideration and not environmental. It says, “Further studies are needed to determine the contributions of the genes we identified to the interplay between dietary choices and disorders of neural function and lipid metabolism.”
“A better understanding of the physiologic pathways involved in choosing a vegetarian diet is needed in order to design more effective dietary recommendations and interventions,” considers the study. Scientists also believe this could open wider doors to studying many diseases and their causes clearly. Nevertheless, none can ignore the impact of the idea that the study puts forth and will give birth as it sees advancements in science.
