Omega-3 deficiency in animals leads to impaired glucose transporter function in the brain due to stiff cell membranes, affecting cognition and potentially leading to tau tangle accumulation.

“When you have a cell membrane that's not getting omega-3 and uh in the in the brain, what happens is and there's studies that have shown if for example you take animals like mice and you make them omega-3 deficient, their glucose transporters aren't functioning right because they're structurally like the membranes too stiff and so the transporter is not right and so glucose can't get into the brain.”
