Considerations for Veg and Non-Veg Food

The debate between vegetarianism and non-vegetarianism has long been a discussion topic due to a lack of conclusive data. Both vegetarian and non-vegetarian diets offer unique advantages and disadvantages. Therefore, food considerations including veg or non-veg should be based on scientific facts. This article presents brief conclusive scientific studies on the same to consider your balanced diet.

A recent study published in Advances in Integrative Medicine compared the health outcomes of different dietary patterns. The study includes anthropometric measurements, sleep quality, mindfulness in eating and overall health. As per the study, individuals following a vegetarian diet had better weight management outcomes, sleep quality, healthy BMI and significantly higher levels of mindfulness in their eating habits. In addition, vegetarian foods have a significantly lesser environmental impact. However, non-vegetarian foods are often nutritional rich and easily available.

Advantages of Vegetarian Food

1. Health Benefits

Vegetarian diets are often associated with numerous health benefits. This is possible because plant-based foods are directly extracted from producers where the accumulation of toxic chemicals is limited. However, animal food often contains more amount of accumulated toxic pollutants due to bioaccumulation. Research suggests that vegetarians have a lower risk of obesity, heart disease, hypertension, type 2 diabetes and cancer. These health advantages are attributed to the higher intake of fruits, vegetables, whole grains, nuts, and legumes. These foods are highly rich in essential vitamins, minerals, fibre, and antioxidants.

2. Environmental Impact

One significant advantage of vegetarianism is its positive environmental impact. Livestock farming, particularly for meat production, contributes significantly to greenhouse gas emissions, deforestation, water pollution, and habitat destruction. Individuals can reduce their carbon footprint and contribute to sustainable food production by shifting to a plant-based diet.

Disadvantages of Vegetarian Food

1. Nutritional Concerns

While vegetarian diets offer numerous health benefits, they may pose certain nutritional challenges. Vegetarians require more attention to obtaining adequate amounts of protein, iron, calcium, vitamin B12 and omega-3 fatty acids, as these nutrients are primarily found in animal-based foods. Failure to meet these nutritional needs could lead to deficiencies and health complications.

2. Limited Food Choices

Another drawback of vegetarianism is the potential for limited food choices, especially in regions where plant-based options are less accessible. This limitation may lead to dietary monotony and make it challenging to meet nutrient requirements, particularly for individuals with specific dietary preferences or restrictions.

Advantages of Non-Vegetarian Food

1. High Protein Content

Non-vegetarian diets are rich in essential proteins for muscle growth, tissue repair, and overall body function. Animal-based foods such as meat, poultry, fish, and eggs provide complete protein sources containing all nine essential amino acids necessary for human health. Therefore, adequate consumption of essential protein is crucial for maintaining muscle mass, supporting immune function, and promoting satiety.

2. Nutrient Availability

In addition to essential proteins, non-vegetarian foods are abundant sources of essential nutrients like iron, zinc, vitamin B12 and omega-3 fatty acids. These nutrients are required for various physiological processes, including oxygen transport, immune function, cognitive development and cardiovascular health. Incorporating animal-based foods into the diet ensures a diverse nutrient intake and helps prevent nutrient deficiencies.

Disadvantages of Non-Vegetarian Food

1. Health Risks

Despite the nutritional benefits, excessive consumption of red and processed meats has been linked to an increased risk of chronic diseases such as cardiovascular disease, stroke, type 2 diabetes, and cancers. Moreover, concerns about antibiotic resistance, foodborne illnesses and ethical considerations surrounding animal welfare are important factors. Therefore these factors need to be considered before choosing non-vegetarian foods.

2. Environmental Consequences

The production of non-vegetarian foods has significant environmental consequences. Livestock farming requires more land, water, and feed resources. This may lead to deforestation, water scarcity, soil degradation, and biodiversity loss. Moreover, animal agriculture is a major contributor to greenhouse gas emissions, further exacerbating climate change and environmental degradation.

A comparative analysis of vegetarian and non-vegetarian diets reveals complex relationships between dietary choices, health outcomes, and environmental impacts. While both dietary patterns offer distinct advantages and disadvantages, the optimal diet varies depending on individual preferences, cultural practices, nutritional requirements, and ethical considerations. Based on the discussion, it is clear that optimal nutrition required for human beings cannot be achieved by one type of food.

Balanced diet for optimal health

The scientific analysis suggests that human physiology aligns more closely with vegetarian animals. For example, tooth structure, water consumption methods, visual acuity shortly after birth, flat nails, elongated digestive systems, thermoregulation, communal living patterns, peaceful coexistence, etc. This suggests a predominantly plant-based diet for human beings. Nevertheless, to achieve optimal health, the human body’s nutritional needs necessitate elements derived from both vegetarian and non-vegetarian sources. Therefore, food considerations including veg or non-veg require a proper understanding of the body’s requirements rather than other criteria. It can be noted that neither extreme is necessarily superior or inferior.

1. Nutritional Diversity

The human body requires diverse nutrients and minerals to function optimally. Essential nutrient type and quantity vary significantly between the two categories. Therefore, this requirement is easily achievable by balancing the vegetarian and non-vegetarian foods in the diet. However, it isn’t easy to achieve using a single type of food.

2. Deficiency Risks

Skipping either vegetarian or non-vegetarian food categories can predispose individuals to nutrient deficiencies. For instance, vegetarians may be at risk of insufficient vitamin B12, iron, zinc and omega-3 fatty acids, primarily found in animal products. Conversely, those following a strictly non-vegetarian diet may lack adequate fibre, antioxidants, and certain vitamins abundant in plant-based foods.

3. Survivability and Health Implications

Contrary to common misconceptions, individuals can sustain themselves on a well-planned vegetarian diet that meets their nutritional needs. However, the same cannot be said for those exclusively consuming non-vegetarian foods. Nutrient deficiencies arising from imbalanced diets can lead to various health issues, including anaemia, impaired immune function and neurological disorders.

4. Addressing Nutrient Deficiencies

For vegetarians, addressing nutrient deficiencies often involves supplementation or consuming larger quantities of plant-based foods rich in deficient nutrients. For example, integrating fortified foods such as fortified plant milks and cereals can aid in meeting vitamin B12 needs. Additionally, including legumes, leafy greens, nuts, and seeds can boost iron and zinc intake.

On the other hand, individuals reliant solely on non-vegetarian foods may benefit from diversifying their diet to include more plant-based options. Increasing the consumption of fruits, vegetables, whole grains, and legumes can provide essential nutrients while reducing the intake of saturated fats, cholesterol and toxic chemicals associated with animal products.


While vegetarian diets offer health benefits and environmental sustainability, they may pose nutritional challenges and limited food choices. On the other hand, non-vegetarian diets provide abundant protein and essential nutrients but carry health risks and environmental consequences.

However, considerations of a balanced food incorporating veg and non-veg elements can provide optimal health benefits. By embracing dietary diversity, individuals can ensure adequate intake of essential nutrients while reducing the risk of nutrient deficiencies and associated health complications. Rather than viewing vegetarianism and non-vegetarianism as mutually exclusive, it is crucial to recognize the value of both dietary approaches in promoting long-term health and well-being.
