Fish: It’s What’s for Dinner

Everywhere, April 2017—(We wrote this piece about seven years ago, but it’s still potent. Here’s a freshened-up version, for new and present readers alike.)

The genetic "gifts" we inherit from our forebears are not always welcome. If we as potential recipients had any say about those tiny critters floating around inside grandma, we might be better off taking a pass. While some genetic gifts can be just what the doctor ordered, there are others that can cause serious health problems. And it's been found that the potency of these offenders is linked to environmental factors such as diet and lifestyle.

As part of ongoing research, news about one of these genes surfaced recently. Known as APOE4, it's found in every human body, and can be a risk factor for Alzheimer's disease. Because of this, animal models were developed to investigate the effects of diet and environment on APOE4.

Preliminary results had the investigators smiling broadly: When the mouse models were given a diet high in Omega-3 oils and low in cholesterol, the negative effects of the gene were significantly reduced.

APOE is positively influenced by the good oils found in fish. So the scientists worked up three different diets: a normal one, another high in cholesterol and a third high in fish oil.

The diet high in fish oil, (found primarily in fatty fish such as salmon, cod and tuna) scored well, and indicated that in general, good diets that include this additive can specifically counteract the negative effect of Alzheimer's related genes.

While the idea has been promoted by nutritionists and dieticians for some time, it's one more piece of evidence that fish is good for the brain—and the rest of you as well.

Fish: It's what's for dinner.
