Even after removing the bad oil, nearly 4 out of 10 packaged foods still contained palm oil — which is also high in saturated fat — meaning the overall fat profile didn't get much healthier.
Descriptive
Adult rats don't get any antioxidant boost from vitamin K1, and their blood fats keep getting damaged — unlike baby rats, who do benefit.
Correlational
About 4 in 10 of the foods that used to have the bad oil were just taken off the shelves entirely instead of being changed to use a different fat.
Even though baby rats have more antioxidants in their blood, their red blood cells break down fats more easily than adult rats' cells, meaning their blood cells are naturally more fragile.
When companies stopped using the bad oil (PHOs), more than half of them switched to palm oil — which is high in saturated fat, another type of fat linked to heart disease.
Even though vitamin K1 helps protect fats in baby rats' blood, it doesn't help protect the proteins in their red blood cells from damage.
After the law changed, not a single packaged food product in Poland had the harmful oil called partially hydrogenated oil on its label anymore.
Giving baby rats vitamin K1 helps their blood fight off damaging molecules called free radicals, and this helps keep their fats from breaking down too much.
Before a new law took effect, about 7 out of every 100 packaged foods in Poland had a type of oil called partially hydrogenated oil, mostly in things like soups, bread, and candy.
A substance called conjugated linoleic acid, found in dairy and meat, might help your health in some ways.
Not all trans fats are the same — some might be more harmful, and others might be less harmful, depending on where they come from.
Trans fats in food come from two places: factories that process oils, and the stomachs of cows and other grazing animals.
A type of fat found in milk and meat turns into another fat called conjugated linoleic acid in the body, and that second fat might be good for your health.
Man-made trans fats and natural trans fats in dairy and meat are made of different chemical parts, and these differences might affect your health in different ways.
This method is especially useful for lab tests that look at how free radicals damage cholesterol, because it keeps the cholesterol from getting damaged before the test even starts.
This new method works with the same machines and skills labs already have — no new expensive tools or expert training needed.
The old way of cleaning LDL takes longer and causes more damage to the molecule — like rust forming on metal — while the new quick method keeps it healthier.
The same quick method used for LDL can also be used for Lp(a), with one extra short step, and it likely keeps Lp(a) from getting damaged by air too.
This new quick way to clean LDL cholesterol from blood samples keeps it from getting damaged by air exposure better than the old, slower methods, which means scientists can study it more accurately.
The tiny capsules keep the antibacterial oil working longer in the meat, so it doesn’t wear off as quickly as when the oil is just mixed in.
This special wrap helps keep the meat from becoming too acidic or too basic over time, which helps it stay fresh longer.
When carvacrol is trapped in tiny capsules, it works better at stopping cold-tolerant bacteria in meat than when it's just mixed in, especially after 9 days of refrigeration.
This special wrap slows down the growth of bacteria in ground beef, keeping it safer to eat longer than regular packaging.
A special plastic wrap made from cassava starch and a natural oil called carvacrol, trapped in tiny capsules, helps keep ground beef from going rancid longer than regular wraps.
