Linoleic acid might make certain human ovary cells more inflamed, based on lab tests with a specific dose.
When a certain type of human ovary cell is exposed to a specific amount of linoleic acid, it starts to die off more — and this might explain why high levels of this fat could mess with egg development.
Algae-based protein is way more expensive than soy protein—like 5 to 10 times more—so even though it's better for the planet, it's too costly to make on a big scale right now.
Using sound waves to extract protein from algae makes it easier for animals to digest and use the protein.
Growing protein from tiny algae uses way less land and water than raising cows — like 95% less land and way less water — so it could be a smarter way to make food without hurting the planet.
Using quick bursts of electricity can help pull proteins out of tiny algae more efficiently, keeps them in better shape, and uses less energy than smashing the cells with beads.
Microalgae like Spirulina and Chlorella are packed with protein—sometimes even more than soy or beef—making them a super food option for people and animals.
Cows on a smarter grazing system in Brazil gain more weight each day than cows on traditional grazing — about 0.78 vs. 0.58 kg per day — which means they're growing better with this new approach.
Using a smarter grazing method called Voisin Rational Grazing might help more types of grass grow in Brazilian pastures, especially two kinds called Brachiaria brizantha and Panicum maximum, compared to how most farmers graze their animals.
Using a smart grazing method called Voisin Rational Grazing might cut down weeds in tropical pastures by 16%, making the grass healthier and easier to manage than if animals just graze all the time.
Using a smart grazing method called Voisin Rational Grazing can boost grass growth by over 30% in Brazil’s pastures, meaning more food for cows and other animals in similar climates.
In dry Mediterranean grasslands, rotating animals between pastures doesn’t seem to make the soil’s tiny life or structure any different than leaving them in one spot all the time — even though other soil traits do change.
Healthy soil in dry Mediterranean pastures depends a lot on carbon from old plants and microbes — the more of it there is, the better the soil holds water, cycles nutrients, and supports helpful fungi and nitrogen release.
Rotating where animals graze helps the soil stay healthier in dry areas — it boosts carbon, nitrogen, and the soil's ability to hold water compared to letting animals graze the same spot all the time.
The more plants covering the ground in damaged savanna pastures in Brazil, the less soil gets washed away — and plants explain a big chunk of why some areas lose more soil than others.
Most of the eroded land in a Brazilian savanna watershed is in damaged pasture areas, and the biggest chunk of that land loses soil at a rate of 20 to 40 tons per hectare every year.
Most of the pastureland in this part of Brazil's savanna is somewhat damaged — not the worst, but not healthy either — and this 'medium damage' covers more area than any other type.
Adding a small amount of microalgae to chicken feed boosts omega-3s in egg yolks but doesn’t change how the eggs behave when cooked or used in food manufacturing — they still work just as well.
Adding a type of algae to chicken feed makes egg yolks more orange-red, which people still find tasty and acceptable.
Feeding hens a little bit of algae with good fats makes their eggs healthier by lowering risky fats linked to heart problems.
If you feed hens a special algae with healthy fats, their eggs end up with a better fat balance that's better for your heart.
If you feed hens a special algae supplement for about a month, their egg yolks get a big boost in a healthy fat called DHA — but after 30 days, adding more doesn’t help because the yolks can’t hold any more.
Feeding quails natural plant pigments from paprika and marigolds might help keep their eggs fresher for longer by slowing down changes inside the egg as it's stored.
If you feed Japanese quail a diet with 0.8% paprika, marigold, or both, they don’t turn their food into body weight or eggs as well as quail that don’t get those supplements.
