Wild Alaskan salmon

“It’s all about omega-3s,” says health guru Andrew Weil, MD, explaining why fish like sockeye top his must-eat list for women. All of our experts agreed: wild salmon packs a wallop with two kinds of heart-healthy omega-3s, including DHA, a fatty acid essential for a healthy pregnancy.

Omega-3s also boost mood, fight depression, and may protect against Alzheimer’s disease and cancer. Add in salmon’s lean protein and vitamin D (a critical nutrient many women lack), and you’ve got yourself a near-perfect food.

How much you need: Eat at least two servings of a fatty fish like salmon a week, the American Heart Association recommends. Can’t find it fresh? Canned wild Alaskan salmon is almost as good, says Steven Pratt, MD, author of SuperFoods Rx and SuperHealth.
