Meat consumption

The relationship between meat consumption and a healthy and sustainable diet is a hot topic in social debate. Wageningen University & Research is studying the effect of eating meat on health, sustainability and climate. We also collect data on meat consumption, look at consumer behaviour and preferences, and investigate meat substitutes and alternative sources of protein. Our research can be used by public authorities, businesses and individuals to help them make informed decisions.

How much meat do the Dutch eat?

The average Dutch person eats just over 77 kg of meat per year. This refers to consumption based on carcass weight, i.e. meat including bones, fat and skin. As a rule of thumb, roughly half of this is actually consumed as meat and meat products. There was a slight drop in meat consumption between 2010 and 2015, for 2018 the figures show a slight increase for the first time in 10 years.

About half of Dutch people call themselves ‘flexitarians’. This means that they don’t eat meat with their main meal at least three times a week. The proportion of vegetarians is stable, at just under five percent of the Dutch population.

Meat and health

Meat contains high concentrations of important substances that are needed for the functioning of the human body – as a source of energy, for cell division and for the development of bones and muscles. Nutrients in meat include (among others) fats, protein, vitamins B1, B6 and B12, vitamin D, iron and zinc.

For many people, meat is an important source of protein in their diet. The recommended amount of protein for adults is generally 0.8 grams per kilogram of body weight, so a person weighing 70 kg needs 56 grams of protein per day.

The average daily consumption of protein in the Netherlands is 109 grams, of which 74 grams are animal and 35 grams are plant protein, so on average we consume a good deal more protein than we need.

Who needs more protein?

Some groups of people need a little more protein. These are vegetarians, elderly people, children, and pregnant or breastfeeding women. People with certain health conditions or injuries and strength and endurance athletes also need more protein.

What if you eat too much meat?

Eating too much meat poses health risks. Red meat and, in particular, processed meat such as meat products are associated with stroke, type 2 diabetes and colon cancer.

What if you eat little or no meat?

According to food scientists, a diet with less meat or none at all can be healthy if you eat other products that contain enough protein, iron, vitamin B1 and vitamin B12.

It is not yet known whether vegetable protein is as healthy as animal protein. Protein is an important building block for the muscles. Vegetable protein is made up of amino acids that are different from those found in animal products. Research is being done into the effect of eating only vegetable protein on muscle mass and quality.

Sustainable consumption

A modest amount of meat fits into a sustainable diet. Livestock can play a useful role in food production: we can feed animals biomass that humans can’t eat, such as leftover streams and grass that grows on soils that are not suitable for arable farming. This has, in fact, been the traditional role of farm animals: to convert leftover streams and biomass that is inedible to humans into high-quality protein sources such as dairy, eggs and meat.

More about the circular agrofood system

An essential element of a circular agrofood system is that we feed animals leftover streams and grow as little feed specifically for animals as possible, as is currently done on a huge scale.

The transition to a circular agrofood system in which animals are fed exclusively on by-products, leftover streams and grass represents a radical change that presents major challenges for aspects such as nutritional balance and food safety.

Preliminary calculations show that the most sustainable diet in a circular food system contains about 20 grams of animal protein per day.

Animal production and sustainability

Food production has an impact on the environment (soil, air and water) and our living environment. WUR is doing research on the effects of animal production (meat, dairy, eggs) on the environment and our surroundings. These include emissions of phosphate, ammonia and fine particulates.

More about climate-smart livestock farming

Livestock farming accounts for about seven percent of greenhouse gas emissions in the Netherlands. Cows and other ruminants are responsible for a significant part of this because they emit the greenhouse gas methane.

In the Netherlands, most cows are kept primarily for milk production. About three percent of all CO2 equivalents in the Netherlands are released as a result of fertilising agricultural and grazing land for cows.

Wageningen University & Research is doing research on how greenhouse gas emissions from livestock can be reduced. For example, we are looking into whether modifying the feed can reduce emissions and whether emissions from manure can be reduced by separating, cooling or mixing oxygen into the manure. Some cows naturally emit less methane, and this can be taken into account in breeding.

Protein transition

As the world population grows and prosperity increases, demand for meat and dairy products is expected to increase rapidly all over the world over the next few decades. At the moment, the supply of protein is unevenly distributed around the world. There is overconsumption in rich Western countries, especially of animal protein, and malnutrition elsewhere in the world. Protein transition involves the transition to a sustainable food system in which everyone can consume a sufficient amount of high-quality protein.

More about protein transition

A sea change is needed, in both the production and the consumption of protein.

If we are to produce sufficient protein without depleting the earth, we need a more diverse supply of protein for feed and food. Protein from plants (including seaweed and algae), microbes and invertebrates (including insects and shellfish) can contribute to a healthy diet that does not do excessive harm to the earth.

WUR is investigating which strategies are most effective at getting people to switch to a sustainable and healthy diet with different types of protein.

Meat substitutes and alternative protein sources

WUR is working on the development of various technologies for optimising the quality of meat alternatives. Shear-cell technology is a revolutionary method of creating meat-like structures which enables us to produce meat substitutes on a large scale. Over the long term, 3D food printing will allow us to create meat alternatives with a taste and texture that is tailored to personal preferences.

More about meat alternatives

Meat alternatives that are available today are not popular with some consumers because they are seen as ‘artificial’. Wageningen University & Research is working on tasty alternatives based on more benign production processes and fewer processed ingredients.

Food safety

Meat is an animal product, and that incurs risks. Treating sick animals with antibiotics, for example, is permitted in the Netherlands after consultation with a vet. Residues of these antibiotics can accumulate in the meat, but in the Netherlands we have meticulous inspection programmes to monitor this. WUR is developing methods to make these inspections ever more efficient and effective.

More about antibiotic resistance

Excessive use of antibiotics in livestock farming can lead to the formation of resistant bacteria. And that can incur risks for humans and animals. We are studying the risks and control of antibiotic use in Dutch livestock farming, which has seen a significant decline in recent years.
