You know eating healthier is good for you. But did you know it benefits the environment, too?
Video of the Day
That's right: Consuming foods associated with improved health and lower risk of disease — like whole-grain cereals, fruits, vegetables, nuts, legumes and olive oil — is better for Mother Earth, according to a large analysis published October 2019 in the Proceedings of the National Academy of Sciences (PNAS).
Choose Mostly Plant-Based Foods
Researchers tracked the dietary patterns and health outcomes of tens of millions of people who ate Westernized diets and found that nutritious foods — apart from fish — caused less harm to the environment than foods linked to a higher risk for type 2 diabetes, stroke, coronary heart disease and colorectal cancer, such as unprocessed and processed red meats.
The reason? Overall, producing plant-based foods involves less global greenhouse gasses (GHG) and land use, and it has less of an effect on fresh-water scarcity and nutrient pollution compared to manufacturing animal products.
Eat Fish in Moderation
OK, so what's the deal with fish? It's true that fish are super healthy for you, but they do have a greater impact on the environment than plant-based proteins like nuts and legumes. According to the PNAS study's authors, this is due in part to the wide variety of fish production methods, some of which create more GHG emissions than others.
This doesn't mean you should slash the swimmers from your diet completely, but rather focus on adding more plant-sourced foods into your daily menu.
You Should Still Limit Processed Foods
And what about ultra-processed and sugary foods? Since, in general, these products aren't sourced from animals, they tend to have fewer negative environmental effects too. But that's no excuse to chow down on junk.
Remember, ultra-processed foods contain fewer nutrients but are jam-packed with sugar, salt, saturated fat and additives, which can boost your risk for chronic diseases and an early death, per Harvard Health Publishing.
Lower Your Environmental Impact Even More
The good news? Making better decisions about food can help you live longer and leave a smaller footprint on Mother Earth — a win-win situation.
So, in addition to adding more eco-friendly plant-based foods to your diet and cutting back on red meats, what else can you do to keep the environment in good shape?
A few small adjustments to your food and shopping habits can go a long way, says Leslie Langevin, RD, author of The Anti-Inflammatory Kitchen Cookbook, who offers the following tips for improving environmental sustainability:
- Opt for organic foods, which use fewer pesticides and encourage better land use practices.
- Buy locally sourced fruits and vegetables whenever possible — reducing foods' transportation distance results in harmful CO2 emissions.
- Choose food items with recyclable packaging and shop with your own reusable grocery bags.
