Eating meat, especially beef, gives your body all the nutrients it needs to survive and thrive — and your body can actually use them well.
Your body absorbs iron and vitamin A from meat and animal products way better than the versions found in plants.
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.
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.
Animal proteins are easier for your body to break down and use than plant proteins, according to scientific scoring methods.
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.
Plants make natural poisons to protect themselves, and if we eat them, these can sometimes harm our bodies.
Scientists looked at old human bones from before farming and found clues in the chemicals that show these people mostly ate meat.
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.
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.
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.
This is about special plastic-like films that break down in soil. Films without tiny zinc particles lost 72% of their weight, while those with zinc particles lost only 47.5% after 120 days.
When more zinc oxide nanoparticles are added to special films, they become better at killing germs, which you can see by bigger clear rings around the film where germs can't grow.
A special type of film made with certain chemicals and tiny zinc particles can stop bacteria from growing, and how well it works depends on how many zinc particles are used.
Taking high-dose zinc lozenges for a cold for up to two weeks is generally safe and well-tolerated, with few side effects, according to studies with nearly 200 people.
Zinc lozenges help with cold symptoms not just in your throat where the zinc is strongest, but also in your nose just as much.
Taking high-dose zinc lozenges doesn't really help shorten headaches or fevers when adults have a cold, according to a review of three studies.
Taking high-dose zinc lozenges when you have a cold can cut down how long your muscle aches last by more than half, which is the biggest improvement for cold symptoms like this.
Taking high-dose zinc lozenges when you have a cold can shorten how long your nose runs by about a third, and studies show this works consistently for adults.
Taking high-dose zinc lozenges early when you have a cold can cut your cough time almost in half, making it one of the best symptoms to treat.
Taking high-dose zinc lozenges right when you start feeling a cold can shorten how long you're sick by almost half, according to studies in adults.
When you add more salt to a mix of certain chemicals (citrate and metals), it makes them stick together less tightly, just like a science rule says should happen.
When copper and zinc are mixed together with citrate (a natural acid), they form a special combined structure that holds together much better than when either metal is alone with citrate. This...
Copper sticks to citric acid much tighter than zinc does, like a stronger magnet holding on better, when you test them the same way.
