Food tips frm Grandpa

My grandfather was a wonderful man who loved cookies. When I visited his lovely, old house surrounded by trees, flowers, vegetable gardens, and lawns, we shared all sorts of cookies, always paired with a large glass of cold milk. Over the years, they became so closely associated with visiting Granddad that now, whenever I have one, I feel buoyed by a swell of happy memories.
As it turns out, scientists have a solid explanation for that burst of good cheer. Studies by Richard Wurtman, MD, and Judith Wurtman, PhD, at MIT have shown that snacking on readily digested carbohydrates, such as those in a cookie or bagel, can raise the brain's level of the chemical serotonin, the very same target of modern antidepressant medication.
Of course, other foods are reputed mood boosters, too — though their reputations may not always be deserved. Before I give you a specific plan that will help you benefit from the MIT findings, let's look at a few. Tea is known as "the cup that cheers," and the caffeine in it can certainly improve energy. But that's a physiological response; no studies have confirmed a direct effect on your spirits. Mood booster? The jury's out. (The same is true of coffee.)
Alcohol is commonly thought of as a good-times libation, but it has a dark side. Although a recent study found that moderate drinkers (two drinks a day for men, one for women) had fewer depressive symptoms than nondrinkers, scores of other studies have established that alcohol in large quantities can be a devastating depressant. Mood booster? Perhaps, but only in small amounts.
As for chocolate, which many of us reach for as a pick-me-up: Australian scientists concluded recently that eating the sweet to lift your spirits "is more likely to prolong than abort the dysphoric [depressed] mood. It is not, as some would claim, an antidepressant." Mood booster? Apparently not. (Stick to a 1-ounce serving if you want to benefit from chocolate's disease-fighting antioxidants.)
That brings us to Granddad's cookies, which can brighten your spirits when eaten judiciously. (Incidentally, carb snacking may be more effective for women because they produce substantially less serotonin than men do.) Now, you won't want to try this regimen if you have diabetes or are prediabetic. But if you qualify, try raising your mood-lifting serotonin levels a couple of times a day by doing the following:
Include protein in each of your three meals.
This will raise blood levels of tryptophan, a chemical that eventually turns into serotonin. The best sources of tryptophan are poultry, seafood, and lean meat.
Have a small carbohydrate snack about 3 or 4 hours after each meal and about 1 hour before your next one.
Make sure that your stomach is empty and that you eat no protein between meals. The carbohydrates should be easily digestible — such as one or two oatmeal cookies, a third of a bagel, a slice of whole wheat bread. This will cause tryptophan in your blood to enter the brain, where it is metabolized into serotonin. Elevated serotonin will improve your mood within 20 to 30 minutes.
If you follow the rules, you'll also fall asleep more quickly at night, because at the end of the day, your brain metabolizes serotonin into the natural sleep aid melatonin. From happy to sleepy, all by way of a cookie. It doesn't get much cheerier than that!
