The Study
Plant-Based Diets for Reversing Disease and Saving the Planet: Past, Present, and Future.
This isn't a science experiment — it's more like an opinion article written by a doctor who knows a lot about food and health. It talks about what other studies have found, but doesn't do its own research, so we can't say it 'proves' anything.
Analysis score
Maximum 0 for a editorial/opinion.
Where the score came from
People can eat both plants and meat, but eating lots of processed foods and animal products is making us sick and hurting the planet. Eating mostly whole plants can help us stay healthy and protect the Earth.

Eating more plant-based proteins and fats instead of animal ones could help people live longer and be better for the planet.
Eating mostly whole plant foods like fruits, veggies, beans, and grains is linked to fewer chronic diseases, living longer, and being better for the planet—so it’s a win-win for people and Earth.
People can digest both plants and meat thanks to how their bodies evolved, but being able to eat meat doesn’t mean they have to eat a lot of it.
Eating a lot of processed foods and animal products might be worse for your long-term health than smoking, and it's a top reason people die early or get sick around the world.
People are actually meant to eat meat, not both meat and plants, because of how our bodies and evolution show we're built for a meat-only diet.
