If you aim to cut back on meat a you want to build muscle strength, you are not alone. After our story on foods that help maintain strength, many of you answered our call and told us that you are trying to increase your protein intake with a plant-based diet.

A new study published in Nature Food now she's found that if people swap red and processed meat for plant-based protein a few times a week, it's good for their health — and it can also reduce the carbon footprint associated with their diet.

The study found that cutting red meat consumption in half led to significant changes. For example, eating it twice a week instead of four times a week will reduce your carbon footprint by 25 % and may increase your longevity. (From ALLISON AUBREY , more at northcountrypublicradio.org)
