A Plant-Based Diet Vs. Red-Meat

We all know that red meat is one of the best sources of protein and is packed full with important nutrients.

A 100-gram portion of raw ground beef provides approximately 25% of the recommended daily intake of vitamin B3 and 32% of the recommended daily intake of zinc. Selenium, B6 and other key vitamins and minerals are also found in red meat. Rich in heme-iron, red meat is also important for maintaining the body’s iron levels.

However, there is growing concern that red meat can also be bad for our health.

Red Meat Linked To Chronic Diseases

plant-based dietIn July 2016, the Journal of the American Society of Nephrology published a study identifying a link between kidney failure and red meat consumption. Researchers found that study participants with the highest intake of red meat had a 40% increased risk of kidney failure compared with participants who consumed little red meat.

Many other studies have indicated that a diet enriched with red meat can increase the risk of cancer and other diseases1, 2. The concern is so heightened that the World Health Organisation has classified processed meats, such as sausages and salami, as a Group 1 carcinogen. Also, burnt or charred meat contains carcinogenic compounds.

The WHO’s International Agency for Research on Cancer (IARC) Working Group has reviewed over 800 studies assessing the relationship between red meat and cancer. The IARC reported that the risk of colorectal cancer is increased by 18% with a daily intake of a 50 gram portion of processed meat. The IARC also documented a link between red meat intake and increased risk of pancreatic, colorectal and prostate cancers.

A Decline in Red Meat Consumption

Red meat is a staple food in many households. However, there has been a steady decline in the consumption of red meat in favour of plant-based diets.

In 2013, marketing intelligence agency Mintel reported that 12% of people in the UK were either vegetarians or vegans. This figure increased to 20% among people aged between 16 and 24.

Several years later, this trend is continuing, with more people opting for plant-based diets.

The Health Benefits of Plant-Based Diets

Plant-based dietResearch has shown that plant-based diets can be beneficial for health and disease prevention. A study published in the Nutrition Bulletin in November 2016 highlighted some of these advantages.

Authors, Harlan and Garton, conducted a meta-analysis of epidemiological studies and found that plant-based diets could reduce the risk of cardiovascular disease and type 2 diabetes by 20-25%3. It was also confirmed that plant-based diets reduce the incidence of obesity.
