Nuts! No Guarantee of Weight Loss
Nuts are getting a lot of good health press lately. “Go nuts and still lose weight,” proclaims a nutrition columnist in Live Science. The New York Times published an ode this week to the wonders of nuts as a weight-loss aid. It’s quite a turnaround for nuts, which were out of favor in the low-fat everything 80s and 90s.
Nuts have a lot going for them. They are high in fiber, protein, and unsaturated fat. They are very satisfying. Snacking on nuts makes you likely to consume fewer calories later in the day. Even though they pack a lot of calories, research has shown that their calories are not well absorbed. And a study of two large cohorts of health professionals found that more frequent consumption of nuts links to a reduced risk of death from all causes.
It helps to have smart nutrition scientists like Richard Mattes at Purdue and others documenting all these benefits. Nut producers have wisely invested in nutrition research by independent-minded scientists like Mattes.
But with this love-fest for nuts, is it possible we’re going a bit over the top? In a word, yes. There’s no definitive evidence that nuts will make you lose weight, though there’s plenty to suggest that they might prevent weight gain.
Good, healthful foods (including nuts) are just that — good healthful foods. They are not medicines or weight-loss aids. “Eat more” is a great food marketing strategy, but lousy health advice unless you’re suffering from an eating disorder or wasting syndrome.
Eat well is better advice.
