Nutrition has never been so hot. According to Elizabeth Somer, registered dietitian and author of “Eat Your Way to Sexy,” recent research has enhanced the field of nutrition. From vitamins to oats, check out some more of the recent findings. Read about the first four discoveries here.

Hot Discovery #5: Omega-3s for mood, mind, and memory

The DHA omega-3 fats in fatty fish are the building blocks of healthy brain cells and must come from your diet because your body does not produce them. Research from Oxford found DHA supplements could help improve reading in underperforming children and help curb behavioral problems. In 2006, the American Psychiatric Association even added this fat to its recommendations for treating depression.

Aim for at least two servings a week of DHA-rich salmon or include DHA-fortified foods in your diet. Try ActiLean Snack Bars or take a supplement that supplies at least 200 milligrams of DHA like Ovega-3.

Hot Discovery #6: Resveratrol: The anti-aging secret of red wine

Resveratrol is a polyphenol found in abundance in red wine and in lower amounts in red grapes, peanuts, pomegranates and berries. It is an antioxidant that helps turn on cells’ production of anti-aging substances. It can also speed cell repair.

Hot Discovery #7: Berries: Beyond just tasty

Because the antioxidant mix in berries is so powerful, they are one of the most nutritious foods in the diet. A hot area of nutrition right now is berries’ phytonutrients, which are compounds that can help protect cells from disease and aging.

You should aim for at least one cup of berries a day, most days of the week. Select the darkest berries that are richly hued from skin to core for the strongest antioxidant power.

Hot Discovery #8: Nuts can aid in weight loss

We’ve often been told to stay away from fattening nuts and nut butters. However, nuts contain two of the three most helpful ingredients for weight loss: fiber and protein, which fill us up and keep us satisfied. They also are packed with vitamins, minerals, healthy fats and a few of those phytonutrients so important for health. Just be careful of the serving size. Stick with 1 ounce, or about 12 nuts, to ensure you don’t consume too many calories.
