Taking fish oil supplements with EPA and DHA over time makes the membranes of your red blood cells more filled with these types of fats, making them more flexible but also more prone to damage from oxidation.

Descriptive

Trans fats from dairy and meat (vaccenic acid) don’t seem to make insulin resistance worse in overweight women, even when eaten at levels higher than typical industrial trans fats.

Correlational

In healthy young people, eating more trans fat for a month doesn’t make their insulin work worse than eating the same amount of butter or olive oil.

Correlational

Japanese people living in the U.S. have similar levels of this unhealthy fat in their blood whether they have diabetes or not, suggesting that their overall diet might mask any link between trans fat and blood sugar problems.

Correlational

Japanese people with diabetes have more of a certain unhealthy fat in their blood than those with normal or slightly elevated blood sugar, hinting that processed foods might play a role in their condition.

Correlational

People in Japan who have more of a specific fat (elaidic acid) in their blood—usually from processed foods—tend to have higher insulin resistance, which means their bodies don’t use insulin well, but this link gets weaker when you account for high triglyceride levels.

Correlational

Even when people ate a very high amount of trans fats—either artificial or from dairy—their blood proteins didn’t change enough to be picked up by the method used, meaning this way of studying proteins might not be good for spotting diet effects.

Descriptive

Even when people ate a lot of a specific trans fat found in dairy (CLA), their blood proteins stayed pretty much the same, so this type of fat probably doesn’t change how the body uses proteins in the blood.

Descriptive

Even when people ate a lot of artificial trans fats—way more than normal—their blood proteins didn’t change much, so these fats might not mess with the body’s protein signals in a big way.

Descriptive

When older adults with memory problems eat more omega-3 fats from fish or supplements, their bodies show less of a type of cell damage linked to aging and brain decline.

Correlational

Older adults with memory issues have more harmful oxidative damage in their blood compared to healthy older adults, which may be linked to their cognitive problems.

Descriptive

Elderly people with memory problems who eat more fish oil-like fats (DHA and EPA) tend to have less damage from harmful molecules in their blood, which might help protect their brains.

Correlational

Fish oil and chemo together cause more oxidative damage in tumors than either alone, but that’s not the whole reason the tumors shrink — something else (like GPX suppression) matters more.

Mechanistic

Fish oil only affects the cancer cells’ ability to handle stress — not the healthy liver or colon — which may mean it’s safer and more targeted.

Descriptive

Giving methylene blue while brain cells are still starved makes things worse — it only helps if you wait until oxygen and sugar are restored.

Descriptive

Unlike some toxins, methylene blue doesn’t make harmful free radicals in brain cells after they’ve been starved.

Descriptive

Mice with breast tumors that eat fish oil stay healthier and gain weight before treatment, while those on regular oil lose weight — suggesting fish oil helps fight cancer-related wasting.

Correlational

Methylene blue helps brain cells store more sugar as glycogen after being starved, which may help them recover energy later.

Mechanistic

Even when given an antioxidant (vitamin E), tumors in fish oil-fed mice still get more oxidative damage after chemo, meaning they’re already under more stress and can’t recover.

Correlational

After brain cells are starved and then get oxygen and sugar back, methylene blue helps them make more of their main energy molecule.

Quantitative

Fish oil makes breast cancer tumors in mice produce less of an enzyme that protects them from oxidative damage, and this makes the cancer cells more vulnerable to chemotherapy.

Correlational

Methylene blue fixes a key enzyme that helps brain cells start using sugar for energy after they’ve been starved.

Quantitative

Feeding mice a diet rich in fish oil changes the fat composition in their breast tumors, and those tumors grow slower when treated with a common cancer drug.

Correlational

Methylene blue helps brain cells take in more sugar, which they need to make energy.
