In mice genetically prone to heart disease, eating certain fats like those in margarine or some oils led to more artery gunk after 16 weeks compared to other fats found in fish or nuts.

When older male mice eat fewer calories, they tend to keep healthier muscles and energy-producing parts inside their cells—especially if their diet includes a lot of saturated fat like from lard.

In male mice eating 40% fewer calories, the type of fat they eat matters — mice live longer on more saturated fats like lard than on unsaturated fats like soybean or fish oil.

In male mice on a severely reduced diet, the type of fat they eat matters — lard (like bacon fat) seems to keep their muscle cells healthier at a microscopic level better than vegetable or fish oils.

Cutting calories helps people get healthier, and while a DNA aging test called DunedinPACE shows some of these benefits, it only catches a small part of the full picture.

A new aging test called DunedinPACE can spot small changes from healthy habits better than older tests, especially after just a couple of years of eating less — making it a better tool for testing anti-aging treatments quickly.

If healthy adults eat 20% less food, it might slow down how fast their body ages — and the more they cut calories, the more it slows, according to one study.

Cutting calories for two years doesn’t seem to change certain biological age clocks in healthy adults, even though other signs of aging improved.

Cutting calories a bit for two years might slow how fast your body ages on a cellular level, according to a study on healthy adults who aren’t overweight.

Certain damaged fats in food can harm gut cells by causing stress and damage, like rusting from inside the cells.

Bosana olive oil extract seems to protect gut cells from damage better than another type of olive oil extract, probably because of the powerful natural antioxidants it contains.

Olive oil has natural chemicals called phenols that might help protect your gut cells from damage caused by unhealthy fats in food.

If you're already eating a really healthy and balanced diet, cutting back on calories probably won't help you live much longer.

For the best health, about a quarter of your fat intake should come from saturated fats, most from healthy monounsaturated fats like olive oil, and around 15% from fresh polyunsaturated fats like those in nuts and fish.

Eating lots of fruits and veggies, some lean meats, and a good mix of healthy fats might help you feel better and live longer.

Regular red meat, like steak or roast, isn't the same as processed stuff like bacon or hot dogs — they're made differently and might affect your health in different ways, so experts say we shouldn't treat them the same when studying their health effects.

If you eat less food, having more saturated fats in your body might help you live longer.

If your food has bad fats, your body uses up its antioxidants fighting those instead of using them to protect your cells and help you live longer.

Polyunsaturated fats go bad more easily than other fats—both in your pantry and in your body—because of their chemical structure, which can lead to more damage in cells.

Fats that are more saturated, like those in butter or olive oil, don’t break down as easily in your body, and that might help you live longer if you're eating fewer calories.

Eating fewer calories might help your body handle a not-so-great diet better by boosting its ability to stay healthy metabolically.

Mice that eat fewer calories live longer, and among those on a low-calorie diet, the ones eating mostly lard seem to live the longest.

The UK meat industry uses the same PR tricks as big tobacco and oil companies—like saying the science isn't clear or that it's your choice—to avoid government rules that might hurt their profits.

The UK meat industry says we don’t need to eat less meat to help the planet—instead, they believe better farming practices and natural carbon storage in grasslands are enough to fight climate change.
