Vegetarian and non-vegetarian foods impact not only the body but also the mind, affecting concentration, learning, and productivity. While some foods can calm and refresh the mind, others energize or dull it. Research has traditionally focused on how food impacts the body, but recent studies examine the mind's influence. Some research indicates vegetarian foods lack protein for muscle growth, but herbivorous animals with robust bodies contradict this. Additionally, the human digestive system and teeth are more similar to herbivores than carnivores, suggesting our bodies are better suited for vegetarian foods which are less stressful to digest. Arguments that vegetarian foods involve killing plants can be countered by noting many foods like fruits involve no killing and

1. Vegetarian vs. Non-Vegetarian foods
Foods that we consume not only impacts the body, but also affects the mind and thus can enhance or hamper a student’s concentration and learning abilities as well as workplace productivity. While some foods can make our minds calm and fresh, some propel us into action, and others can make us dull and inactive. Traditional research seems to have laid excessive emphasis on the impact of food on the body while recent efforts are looking at influence of food on the mind. While some research studies indicate that vegetarian foods are lacking in protein needed for muscle development among others and hence less healthy, herbivorous animals with robust bodies (Elephants, Zebras, Horses, etc.) seem to contradict this.
In addition, we also need to look into the suitability of our bodies for the consumption of various foods; in particular, we need to look at our teeth, saliva, and the rest of the digestive system. Research seems to indicate that the human body indeed takes a lot longer to digest the non-vegetarian food (in comparison with vegetarian food), and hence is more stressful on the body-mind complex. Apparently, even the teeth and the digestive system of the humans are closer in design to the herbivorous animals than the carnivorous animals; for example, the length of the intestines.

2. The consumers of Vegetarian foods are often confounded with questions that vegetarian food involves 'killing' or 'violence against' plants. One argument is that many of the plant products used for consumption can be seen as an 'offering' from the plants like fruits and many vegetables not involving 'killing' of the entire plant or tree; in the case of grains and cereals, it is mostly procured after the ‘lifetime’ of the plants; for example, paddy. The motive to minimize violence in the name of satiating one's hunger, to the extent possible, needs to be encouraged.
