The Undeniable Link Between Animal Products and Human Diseases

Dec 16, 2023

Animal products have been a staple in the human diet for centuries, providing a significant source of protein and essential nutrients. But recent research has shed light on the link between the consumption of animal products and the development of various human diseases.

Cardiovascular Diseases

Studies have shown that a high intake of red and processed meats is associated with an increased risk of cardiovascular diseases such as heart attacks and strokes. The saturated fats and cholesterol present in animal products can contribute to the buildup of plaque in the arteries, leading to atherosclerosis and other cardiovascular issues.

Consumption of animal products, particularly red and processed meats, has been linked to an elevated risk of certain types of cancer, including colorectal, prostate, and breast cancer. The compounds formed during the cooking of meat at high temperatures, such as heterocyclic amines and polycyclic aromatic hydrocarbons, are known carcinogens.


Research has indicated that regular consumption of animal products, especially processed meats, is associated with an increased risk of developing type 2 diabetes. The high levels of heme iron and saturated fats in animal products can contribute to insulin resistance and impaired glucose metabolism.

Animal products, particularly those high in saturated fats, can contribute to weight gain and obesity. The high calorie density of many animal-based foods, coupled with their low fibre content, can lead to overconsumption and subsequent weight-related health issues.

Foodborne Illnesses

Consumption of animal products, especially undercooked or contaminated meats, can lead to foodborne illnesses caused by pathogens such as Salmonella, E. coli and Campylobacter. These infections can cause severe gastrointestinal symptoms and, in some cases, lead to long-term health complications.

Environmental Impact

Beyond the direct impact on human health, the production of animal products has significant environmental implications. Livestock farming contributes to deforestation, greenhouse gas emissions and water pollution, which can have far-reaching consequences for human health and wellbeing.

Plant-Based Alternatives

Given the potential health risks associated with the consumption of animal products, many people are turning to plant-based alternatives. They not only offer a wide range of essential nutrients but are also associated with a lower risk of chronic diseases and can have a positive impact on the environment.

So while animal products have been a traditional part of the human diet, it's vital to consider the potential health implications associated with their consumption. Understanding the link between animal products and human diseases can empower you to make informed dietary choices that promote long-term health and wellbeing.
