What are the Benefits of Eating Low Meat Diet?

Wanna know how reducing meat in your diet can be beneficial. Read on to find out the benefits of reducing meat in your daily diet.

Four diets have been studied in terms of their impact on health, the environment, and animal welfare.

950 kilograms of food and drink are consumed by every citizen in the EU annually—a sizeable quantity, the weight of a small car.

No-meat Diet Everywhere Will Not Solve Climate Change
No-meat diet is not the universal solution to tackle climate change, according to a new study.

‘Many people have diets that are too rich. However, by reducing the amount of food they ate, to what they really need, can have positive effects on health, the environment and animal welfare.’

Globally, food is responsible for a quarter of human greenhouse gas emissions. A large part of this is due to livestock farming: Animals convert only a small portion of the fed calories into meat. Ruminants also produce methane, which further accelerates global warming.

Furthermore, what we eat also has consequences for our health and animal welfare. When comparing diets, these aspects should also be taken into account.

Experts also refer to the optimal health of humans, animals and the environment as the "One Health" perspective. "Studies that apply this perspective to nutrition issues are still rare, however," explains Juliana Paris of the Center for Development Research (ZEF) at the University of Bonn (Germany).

Man Cured Mystery Illness With Raw Meat Diet
An American man switched to a paleolithic diet to treat his mystery illness, that killed his appetite and made him puke everything he ate.

Actual food basket compared with three alternatives

Paris, together with colleagues, conducted an analysis that aims to fill this research gap to some extent. "To do this, we took a look at examples of which products are on the food basket of people in North Rhine-Westphalia," she explains.

Scientists Identify Link Between Diet, Intestinal Stem Cells And Disease
Diet rich in sugar and fat disrupts the ability to constantly renew and develop all types of intestinal cells from intestinal stem cells and can contribute to the development of diseases.

"We then compared this reference diet with three different scenarios: a shift according to the recommendations of the German Nutrition Society (DGE), a shift to a Mediterranean diet with more fish and seafood, and a shift to a vegan diet."

In each of these three scenarios, the foods were chosen to differ from the reference diet as less as possible. "That means, for example, that in the Mediterranean version, we increased the proportion of fish and seafood, vegetables and grain products," Paris says. In addition, the overall product selection should contain the same nutrients in similar amounts as before. This gave the researchers a food basket for each scenario, which they then analyzed further.

Dietitians Play a Vital Role in Weight Loss: Study
Dietitians play a vital role in managing patient's obesity that is often associated with increased risk of type 2 diabetes, stroke, certain cancers, and cardiovascular disease.

"To do this, we relied on various databases," says Dr. Neus Escobar of the Institute for Applied Systems Analysis in Austria, who supervised the work. "They enabled us, for example, to estimate the impact of each diet on certain environmental aspects - such as the amount of greenhouse gases produced during their production or the water consumption. We took a similar approach to assess the impact of each diet on health."

Red meat, for example, is known to increase the risk of certain cancers and cardiovascular disease.

The researchers estimated the consequences for animal welfare using several indicators. These included how many animals lose their lives as a result of food consumption and under what conditions they are kept. "But we also used the number of neurons or the size of the brain in relation to the body to estimate the extent to which the respective animals actually suffer when they are used," explains Juliana Paris.

Fish instead of steak: good for the environment, bad for animal welfare

Any of the three diets would be sustainably beneficial from a One Health perspective. However, this is also at the expense of other aspects. The vegan diet scored best in many areas. However, the production of vegan food involves increased water consumption. "In addition, vegans need to take certain nutrients separately, such as vitamin B12, vitamin D and even calcium," Paris says.

The Mediterranean diet (although healthy) also results in increased water requirements due to the high amount of nuts and vegetables. Moreover, if – as assumed in the study – the meat consumed is completely replaced by fish, its effects on animal welfare are surprisingly negative. As fish and seafood are much smaller than, for instance, cows or pigs, considerably more animals suffer as a result of this diet.

The increased consumption of honey, which requires intensive management of bee colonies, also has a negative impact.

"It’d therefore beneficial to meet less of your overall protein needs from animal sources," Neus Escobar emphasizes. "In addition, many people today have diets that are significantly too rich. If they reduced the amount of food they ate, to what they really need, it might have additional positive effects."

According to the study, the DGE recommendations are going in the right direction. However, in terms of human health, the other two options are better. Nevertheless, the data here also show that if you do without meat more often and instead put whole grains, vegetables and fruits on your plate, you are doing something good not only for yourself, but also for the animals and the environment.
