General Nutrition

Most Americans support new rules requiring calorie counts on chain-restaurant menus and prepared foods in supermarkets, according to an Associated Press-Gfk poll. The long-awaited rules announced by the US Food and Drug Administration have generated opposition from some in the food industry. (See NewsBites, February.) But 56% in the poll supported calorie counts on fast-food menus, 54% at sit-down restaurants, and 52% on prepared grocery foods. Women and college-educated people were more likely to support the rules.

Trends to watch in nutrition-driven consumer choices this year will include growing popularity for seeds and nuts, green tea and ancient grains such as amaranth, quinoa, spelt and freekah, according to a survey of 500 registered dietitians. The survey, conducted for the journal Todays Dietitian, predicted that consumers will eat less red meat and continue to turn away from low-fat diets. Kale and coconut will remain popular based on their perceived health benefits (accurate for kale, less so for coconut), as will healthy choices like Greek yogurt and avocado. The dietitians also predicted consumers will keep trying gluten-free and wheat-free diets to lose weight (rather than out of genuine need, as in celiac-disease patients), despite a lack of evidence supporting such regimens for weight loss, while the so-called Paleo diet will gain in popularity. Also on the rise: misinformation about nutrition, fueled in part by the Internet.

French-fries and potato-chip fans concerned about cancer risk from fried potatoes may have hope on the horizon. Idaho-based J.R. Simplot Co. has received USDA regulatory approval for a genetically modified potato that produces less acrylamide when fried. Thats the naturally occurring chemical linked to concerns about increased cancer risk from fried-potato consumption. The Innate potato, which comes in Russet Burbank, Ranger Russet and Atlantic varieties, also resists bruising, a potential money-saver for growers and processors.

Could extra B vitamins reduce your risk of cognitive decline and dementia by lowering blood levels of an amino acid called homocysteine? That tantalizing promise was put to the test in two recent large-scale studies, and in both cases researchers proclaimed the results disappointing. But other experts say the jury is still out, particularly for people with low B-vitamin status or those who are already experiencing cognitive decline.

Bugs Bunny, always depicted munching on a carrot, may have been onto something. Researchers have found that carrot consumption not only helps insure an adequate intake of a variety of important nutrients and fiber, but may also reduce your risk of chronic disease.

Dagwood Bumstead, the comic-strip character famed for his sandwiches, might want to check his blood pressure. A new analysis of national dietary data by USDA researchers reports that sandwiches account for one-fifth of average sodium intake, a key contributor to hypertension

If a little is good, most Americans are accustomed to thinking, more must be better and a lot must be better still. When it comes to vitamins and minerals, however, it is possible to get too much of a good thing-especially if some of your nutrients are coming from pills instead of food.Remember that most of your vitamin and mineral needs can be safely met by a thoughtful diet, cautions Irwin H. Rosenberg, MD, editor of the Tufts Health & Nutrition Letter. The use of so-called dietary supplements will always be associated with some degree of risk.

New Years brings a brief boost in popularity for black-eyed peas, the key ingredient in the traditional Southern celebratory dish of Hoppin John. But if youre looking for a nutritional bargain, black-eyed peas (aka cowpeas) should be a year-round staple in your pantry.
