Benefits of eating less meat (and more plants)

Fact sheet outlining the health, environmental, culinary, and cost benefits of eating less meat and more plant-based foods

Health benefits

Most Americans eat 1.5 times more protein than the recommended dietary allowance each day. High consumption of red and processed meat has been linked with chronic diseases, including heart disease, type 2 diabetes, obesity, and some cancers. Consuming less red and processed meat and more plant-based foods such as vegetables, whole grains, beans, soy, and nuts can offer a variety of health benefits.  

Reduces risk of heart disease 

The risk factors for cardiovascular disease—which can increase the risk of heart attack and stroke—include eating a diet high in saturated fat, trans fat, and cholesterol. Red and processed meats are higher in saturated fats and cholesterol than most other proteins. One study demonstrated that daily consumption of processed meats was associated with a 42 percent higher incidence of coronary heart disease.  

Diets high in red and processed meats and lower in vegetables, whole grains, legumes, and nuts are associated with a higher incidence of heart disease.  

Eating more healthy plant-based foods in place of meat can help reduce the risk of heart disease.  

Helps reduce cholesterol  

Nearly 25 million U.S. adults have high cholesterol, but many of them are unaware of this, as high cholesterol has no symptoms. Animal products are the only source of dietary cholesterol; they are also the primary source of saturated fat in our diet, which is associated with higher blood cholesterol levels. 

Eating more healthy plant-based meals can help people looking to reduce or manage their cholesterol levels.     

Helps prevent type 2 diabetes  

Approximately one in three American adults has prediabetes—a risk factor for developing type 2 diabetes.  

Eating a plant-rich diet with less meat can help lower the risk of developing type 2 diabetes. Skipping just one half serving of meat per day and replacing it with a plant protein (like beans or tofu) can help lower the risk of developing type 2 diabetes by 15%.  

Kidney health 

In the United States, about 30 million adults have chronic kidney disease—and most aren’t aware of it. One in three American adults are at risk for chronic kidney disease. Risk factors for kidney disease include diabetes, high blood pressure, heart disease, obesity, and family history. 

Reducing consumption of red and processed meat and eating more healthy plant-based foods can help lead to better kidney health, management of kidney disease and a reduction in related risk factors. 

Boosts immune system function  

A healthy plant-based diet can help strengthen your immune system to aid in fighting viruses and help you recover more quickly from illness.  

Fruits and vegetables contain a broad spectrum of nutrients and phytochemicals that help minimize damage to cells and defend against harmful pathogens. 

Supports a healthy weight 

Maintaining a healthy weight can reduce the risk of serious health problems. Substituting more plant-based foods in place of meat can help contribute to a healthier body weight. 

Individuals who eat a plant-based diet usually consume fewer total calories, including calories from fats, and eat more fiber.  

Environmental benefits

Meatless Monday can also help make diets more environmentally sustainable. The livestock industry, especially beef and lamb production, produces large amounts of greenhouse gas emissions that cause climate change. In addition, raising livestock to meet the current demand for meat also contributes to species decline and the depletion of natural resources like land and water. Shifting diets away from high meat consumption can help reduce these environmental impacts. 

Lowers greenhouse gas emissions  

Nearly 15% of global greenhouse gas emissions come from the production of meat, dairy, and eggs—more greenhouse gases than the world’s entire transportation sector—cars, trucks, planes, trains—combined. Eating more plant-based foods can help reduce emissions associated with meat production. 

Saves water 

Meat, particularly beef, has the highest water footprint of all foods. Eating a more plant-based diet has the potential to decrease agricultural water use by 50%. 

Prevents deforestation  

Livestock production uses 75% of the Earth’s agricultural land. Shifting to a more plant-based diet reduces deforestation while decreasing agricultural land use by 80%. 

Reduces species loss 

Livestock production is the biggest human contributor to species decline and has led to an over 60% decline in species populations since 1970.

Helps build healthy habits 

Research suggests that people are more open to trying healthy behaviors at the start of the week. Monday offers a weekly opportunity to “reset” and get back on track. Studies show that people who restart a healthy habit at the beginning of the week are better able to maintain progress over time. 

Fosters discovery of new foods 

Use Meatless Monday as an opportunity to explore new types of recipes, ingredients, and cuisines. Experiment with unfamiliar foods to find new favorites.   

Saves money 

Foods like beans, lentils, and tofu are cost-effective protein sources that are typically less expensive than many types of meat, seafood, and poultry. One study found people saved 16% on food costs by switching to a plant-based diet. 

Expands culinary skills  

With new ingredients comes the need for new cooking methods. Try using different techniques like braising, air frying, stuffing, and puréeing to make meals more exciting.  

Strengthens a growing movement 

Meatless Monday is active in more than 40 countries and available in countless schools, companies, and communities around the world.
