Big teeth in Paranthropus might have helped them survive tough times by letting them eat hard backup foods when their usual meals weren’t available — explaining why their teeth look worn in surprising ways.

Mechanistic

Big, thick teeth in some ancient human relatives might have made it easier to chew tough foods like roots and tubers when their usual food wasn't available.

Mechanistic

Some groups, like the Pima Indians and Australian Aborigines, are seeing more type 2 diabetes because their bodies may be genetically used to handling sugar differently, and today’s processed, high-sugar diets could be overwhelming their systems over time.

Mechanistic

Some groups, like the Pima Indians and Nauruans, might have genes that store energy more efficiently because of past famines and being cut off from others — which helped them survive back then, but now makes them more likely to get type 2 diabetes when eating modern diets full of carbs.

Mechanistic

Eating very few carbs and lots of protein might make your body less sensitive to insulin — not because it's broken, but because it's adapting to save glucose when carbs are scarce, like in ancient times.

Mechanistic

Some groups, like Europeans, might be less likely to get type 2 diabetes because their ancestors started eating farm-based, high-carb diets thousands of years ago—giving their bodies more time to adapt—while other groups, like the Pima or Nauruans, started later and may not have had as much time to adjust.

Causal

Back when humans were hunters during the Ice Age, their bodies might have adapted to use less insulin so their brains and babies could keep getting enough sugar — and that same trait might still be common in people whose ancestors lived that way.

Mechanistic

Eating more plant-based proteins and fats instead of animal ones could help people live longer and be better for the planet.

Correlational

What you eat can change how your genes work and even help protect you from diseases you might be genetically prone to.

Mechanistic

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.

Causal

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.

Descriptive

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.

Correlational

If you eat a meat-heavy diet with not much sugar, your body might need less vitamin C because sugar isn't getting in the way of absorbing it—and meat has enough vitamin C to keep you healthy.

Mechanistic

Eating meat, especially beef, gives your body all the nutrients it needs to survive and thrive — and your body can actually use them well.

Descriptive

Your body absorbs iron and vitamin A from meat and animal products way better than the versions found in plants.

Descriptive

Your body needs certain important nutrients like B12, taurine, and omega-3s, and these are mostly or only found in animal foods like meat and fish — you can't really get them from plants.

Descriptive

When humans switched from hunting and gathering to farming, their brains got a bit smaller—about 11%—and their faces and skulls changed shape too.

Correlational

Animal proteins are easier for your body to break down and use than plant proteins, according to scientific scoring methods.

Quantitative

People can't break down tough plant fiber like cows or rabbits can, so we get almost no energy from it — their stomachs are built for that job, but ours aren't.

Descriptive

Plants make natural poisons to protect themselves, and if we eat them, these can sometimes harm our bodies.

Mechanistic

Scientists looked at old human bones from before farming and found clues in the chemicals that show these people mostly ate meat.

Correlational

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.

Descriptive

Scientists tested special plastic wrap made with tiny particles on tomatoes and found it kept them fresh for a whole month, which means it could be good for keeping food fresh longer.

Descriptive

A special film with tiny zinc particles makes it much harder for water vapor to pass through, keeping things inside much drier than if they were just in an open bottle.
