Introduction
In modern society, many people have begun to support the transition to a vegetarian diet. This diet is based on the principle of the exclusion of meat products and has become very popular among those who choose healthy eating. Although meat products are an essential source of protein for humans, the choice of a vegetarian diet can be driven by various reasons, such as concern for health, ecology, or ethics.
Benefits of Diet
A vegetarian diet has a positive effect on human health. Hopwood et al. (2020) show that vegetarians have a lower risk of developing cardiovascular diseases and some types of cancer. Such a diet can benefit health as it does not contain fat and harmful cholesterol (Lee et al., 2020). This diet also provides healthier fibers, and whole grains and vegetables can benefit human health (Ferraro et al., 2020). Overall, a vegetarian diet contributes to the normalization of cholesterol levels and blood pressure.
A vegetarian diet is also a more ecological and ethical choice. Livestock is one of the primary sources of greenhouse gas emissions. Transitioning to a vegetarian diet helps reduce the ecological footprint by eliminating a negative impact on people’s health and environment (Dakin et al., 2021). Choosing a vegetarian diet is also related to the ethical side of dealing with animals (Fresán & Sabaté, 2019). Many people switch to vegetarianism not to participate in killing animals.
Limitations of Diet
However, a meat diet has some health advantages. Thus, meat is a rich source of protein necessary for regeneration and tissue repair processes and to maintain the immune system in an active state. Meat also contains fats and vitamins of group B (Milfont et al., 2021). However, the alleged lack of protein in a vegetarian diet is a misconception since this diet can provide all the necessary amino acids from plant sources, such as beans, nuts, and grains (Hargreaves et al., 2021). Still, it is essential to balance a diet to be efficient properly.
Conclusion
Generally, a vegetarian diet is more beneficial for health than a meat diet. A vegetarian diet is rich in easily digestible proteins, whole grains, vitamins, minerals, and antioxidants that help maintain a healthy body. At the same time, a meat diet contains elements that can lead to health problems, such as obesity and cardiovascular diseases; therefore, a vegetarian diet is usually better than a meat one.
