The best way to start adopting a more plant-based meal regine is to eat less meat, especially red meat. Why? Because cattle are the top agricultural source of greenhouse gases worldwide—if cows were a country, they’d be the third largest greenhouse gas emitter on earth. Every bit counts. To make sure your plant-based eating habits stick, many experts recommend avoiding going cold turkey overnight. Instead, easing into consuming fewer animal products and more sustainably-sourced plant foods will help ensure long-term success. Make vegetarian or vegan meals a mainstay several nights a week in your house, and start swapping in these delicious vegan alternatives whenever you can. Once you see how delicious your dishes will (still) taste, plant-based eating will be more appealing than ever. P.S. Unlike most natural plant-based proteins, the protein in mushrooms contains all nine essential amino acids, which makes them highly digestible and usable by the body. You can also use firm tofu as a delicious scrambled egg swap. Simply mash it with a potato masher, then gently sauté over medium heat with olive oil, veggies, and black garlic (yum) for three to four minutes until cooked through.
