If you're already taking a statin pill for your heart, adding aged garlic extract might help slow down the buildup of calcium in your heart arteries—kind of like a helpful sidekick for your heart health.

When you give hamsters a special cholesterol-lowering supplement made from plant stuff, it doesn’t matter if you mix it in orange juice or plain water—it works just as well either way.

Causal

Scientists found that a special fatty coating around plant-based cholesterol blockers from canola oil works just as well at lowering bad cholesterol in hamsters as a store-bought version — and these hamsters were eating a fatty diet.

Quantitative

When hamsters eat a fatty, cholesterol-rich diet, giving them a special form of plant-based cholesterol blockers in tiny fat bubbles helps lower their bad cholesterol.

Causal

A chemical called PD 098063 can turn down a protein (VCAM-1) that helps inflammation, but it doesn’t do this by blocking the usual inflammation switch (NF-kappa B)—it uses a different, unknown path instead.

Mechanistic

A natural compound called 2-phenyl-chromene-4-one can block a specific inflammatory signal in blood vessel cells, just like another known compound—this means it’s not the only one that can do this trick.

Mechanistic

A chemical called PD 098063 can stop a harmful inflammation signal (TNF) from making a sticky protein (VCAM-1) that attracts immune cells, but it doesn’t mess with the main alarm system (NF-κB) that usually turns on this protein—so it’s blocking the result without turning off the alarm.

Mechanistic

A chemical called PD 098063 tells the cells lining your arteries to make less of a specific protein signal (VCAM-1) by slowing down how fast the gene for that signal is turned on — it doesn’t change how quickly the signal’s instructions get broken down.

Mechanistic

A natural compound called PD 098063 can block a specific signal that makes blood vessel cells stick to immune cells—this might help reduce inflammation—without messing with other similar signals.

Mechanistic

When your body breaks down quercetin (a plant compound in foods like apples and onions), the resulting molecules aren’t as good at calming down inflammation in your blood vessels as the original quercetin — but they still work a little bit, especially at stopping one specific inflammation signal at a common dose.

Mechanistic

A natural compound found in foods like apples and onions, called quercetin, might help calm down inflamed blood vessels by reducing a signal that attracts immune cells — potentially helping to prevent artery damage.

Mechanistic

A natural compound called quercetin, found in foods like apples and onions, may help calm down inflammation in blood vessels by reducing the stickiness of the vessel lining, which could prevent white blood cells from sticking and causing damage.

Mechanistic

If you eat phytosterols in bread or cereal, they don’t lower your bad cholesterol as much as when you eat them in butter or margarine—by about 0.14 mmol/L less.

Quantitative

The more phytosterols you eat each day—like in fortified margarine or orange juice—the more your 'bad' cholesterol (LDL) goes down, and this pattern keeps happening as you eat more.

Correlational

Eating foods with added plant sterols—like certain margarines or orange juices—can lower your 'bad' cholesterol by about 0.55 mmol/L, which might help reduce your risk of heart disease.

Correlational

If you've had a heart stent placed and still have some clogged arteries left, doing short bursts of intense exercise might help stop those clogs from getting worse.

Causal

If you've had a heart stent and stick to a strict exercise program with intense bursts of activity for six months, you might shrink the fatty buildup in your heart arteries more than if you just follow regular heart health advice.

Causal

If you've had a stent placed for heart disease, doing two 30-minute high-intensity workout sessions a week for six months can actually shrink the fatty plaques in your arteries a little—while just following regular heart advice doesn't make much difference.

Causal

When you add a specific fat called arachidonic acid to blood vessel cells in a lab, it pushes out another healthy fat called EPA, making EPA much less common in the cell membranes—like a crowded room where one person pushes others out.

Mechanistic

When scientists added a specific amount of omega-3 fish oil (EPA) to human blood vessel cells in a dish, the cells soaked up a lot more EPA and ended up with way more of it compared to the bad fats, which is a good sign the cells are using it properly.

Quantitative

When scientists added a small amount of a common fatty acid (arachidonic acid) to blood vessel cells in a dish, it didn’t change the levels of two key molecules involved in cell stress and signaling—so it seems this fatty acid doesn’t mess with the cell’s internal balance under these specific conditions.

Descriptive

When scientists added a specific type of omega-3 fat (DHA) to blood vessel cells in a dish, it made them release a little more of a helpful molecule (nitric oxide) that keeps blood vessels relaxed, but didn’t change a harmful molecule (peroxynitrite) — and this effect was smaller than what another omega-3 fat (EPA) does.

Mechanistic

When scientists added a type of omega-3 fatty acid called EPA to blood vessel cells in a dish, the cells made more of a helpful molecule (nitric oxide) and less of a harmful one (peroxynitrite), which might help keep blood vessels healthier and less inflamed.

Mechanistic

If you're overweight and have type 2 diabetes, losing the same amount of weight helps reduce fat around your pancreas—but eating fewer carbs and more protein makes that fat reduction about one-third smaller than eating a standard diabetes-friendly diet, which suggests what you eat matters, not just how much you lose.
