Drinking a glass of wine a day may lower the risk of Barrett’s esophagus, a condition that precedes esophageal cancer.

Barrett’s esophagus, which affects about 5 percent of the population, occurs when heartburn or acid reflux permanently damages the lining of the esophagus. People with this condition are 30 to 40 times more likely to develop a type of esophageal cancer called esophageal adenocarcinoma. In the last 30 years, the incidence of esophageal cancer in the United States has increased 500 percent.

In this Kaiser Permanente study, researchers looked at 953 men and women in Northern California and found that those who drank one or more glasses of red or white wine a day were 56 percent less likely to develop Barrett’s esophagus. Beer or liquor did not lower the risk, and the protective effect of wine didn’t increased with higher consumption.

“The rate of esophageal adenocarcinoma in this country is skyrocketing, yet very little is known about its precursor, Barrett’s esophagus. We are trying to figure out how to prevent changes that may lead to esophageal cancer,” principal investigator Dr. Douglas A. Corley, said in a Kaiser Permanente news release.

The study was published in the March issue of Gastroenterology. Two other studies in the same issue of the journal reported similar findings. An Australian study found that people who drink wine were less likely to develop adenocarcinoma, and Irish researchers reported that drinking wine reduces the risk of esophagitis, an irritation of the esophagus that follows chronic heartburn and often precedes Barrett’s esophagus and cancer.

It’s not clear why wine may lower the risk of Barrett’s esophagus. Researchers suggest it may be because antioxidants in wine neutralize the damage done by gastroesophageal reflux disease. Or it may be because wine drinkers typically have food with their wine, thereby reducing the potentially damaging effects that drinking alcohol alone can have on esophageal tissue.

The wine study is part of a larger Kaiser Permanente study led by Corley looking at the link between Barrett’s esophagus and abdominal obesity and consumption of dietary antioxidants, fruits and vegetables. That study found that eating eight servings of fruit and vegetables a day and maintaining normal body weight can reduce the risk of Barrett’s esophagus.

“My advice to people trying to prevent Barrett’s esophagus is: Keep a normal body weight and follow a diet high in antioxidants and high in fruits and vegetables,” Corley said. “We already knew that red wine was good for the heart, so perhaps here is another added benefit of a healthy lifestyle and a single glass of wine a day.”

So what’s the prescription for better men’s health? Dr. Mehmet Oz and Dr. Michael Roizen say there are 11 things a man should eat every day –or nearly every day –to keep things running smoothly.

1. Fruits and vegetables provide essential vitamins and minerals that will keep your body healthy. Foods rich in magnesium like beets, raisins, dates and soybeans are especially important because they’ll keep your bowels moving regularly. Dr. Roizen says a man should eat about five handfuls of fruits and vegetables a day.

2. A man should shoot to get about 25 grams of fiber in his diet every day. You can reach this goal through foods like artichokes, lima beans, soybeans, grapefruit, certain berries and whole grains.

Dr. Oz says that eating whole grains isn’t just the latest craze — they offer multiple benefits to health, including achieving proper poop. But first you need to read the label. When you’re buying bread, make sure it says “100 percent whole grain” or “100 percent whole wheat.” If the label says something else –like “7-grain” or “multigrain” — it may not be whole grain.

One of Oprah’s favorite whole grain choices is steel cut oatmeal for its crunchy texture. To reach your goal for fiber, the USDA recommends eating at least three servings of whole grains a day.

3. You can significantly reduce your chances of getting cancer by eating foods rich in folate — you should get about 800 milligrams a day. If you don’t take it as a supplement, you can find folate in orange juice, spinach and other leafy green vegetables.

4. As well as being good for the heart, tomatoes decrease risk of arterial aging, heart disease, stroke, memory loss, impotence and wrinkling of the skin, Dr. Roizen says. And tomato-based products contain lycopene, which has been shown to fight cancer.

But to really reap the benefits, you can’t just put a few slices of an heirloom tomato in your salad. The best way to get the positive effects is by eating 10 tablespoons of tomato sauce a week. “It takes 165 raw tomatoes to equal 10 tablespoons of tomato sauce,” Dr. Roizen says. “So it’s much easier to have tomato sauce.”

Dr. Roizen adds that it doesn’t matter what kind of tomato sauce you have, “as long as it’s cooked, and you eat it with a little olive oil and a little healthy fat because it’s much better absorbed with it.”

5. Walnuts and almonds are excellent for health. And not only are walnuts and hazelnuts excellent sources of heart-healthy omega-3s, but if you eat nuts before sugars (in dishes like pasta or corn on the cob), the fat in the nuts will slow your stomach and help your body most effectively process that sugar. One thing to remember is to keep nuts refrigerated so they don’t oxidize.

6. If there’s a true magic pill could be baby aspirin. “It’s cheap and easy to take aspirin,” he says. “Aspirin has many, many helping elements. It helps your skin, it helps about anything you can imagine. It has some potential risks if people have sensitive stomachs. But for cancer, you’ve got to be on it.”

A man over 35 should take two baby aspirin –or 162.5 milligrams –every day. It can reduce his rise of arterial aging by 36 percent.

7. In recent years, there has been a lot of conflicting information about eating fish. On the one hand, fish is consistently regarded as a terrific source of low-fat protein. On the other hand, there are persistent concerns about mercury and other environmental impurities.

Dr. Roizen says you just have to remember a few great fish — tilapia, salmon, flounder, cod and mahi-mahi –especially if they are wild caught. And not only is salmon a great source of protein, it has the added health bonus of being full of omega-3s, which are important for a healthy heart. According to Dr. Roizen, you should eat a serving of these fish three times a week.

8. It is important to drink eight glasses — or about 64 ounces — of fluid every day. “It helps move the poop and gives you better hydration. It actually cuts down on wrinkles, too, because you hydrate your skin when you take it internally.”

9. Red wine has a chemical in it called rezveritrol, which is a very strong antioxidant that’s also been shown to be heart-healthy

Why red and not white? “Red wine has the material from the skins of the grapes [which provides the rezveritrol]. The white wine has that skin stripped away. So if you’re going to drink wine and you’re going to take the hit on calories, drink red wine.”

10. Coffee is actually good for you in reasonable amounts.

Coffee actually has been shown to reduce liver cancer and to be effective with — or with symptoms of — Alzheimer’s and Parkinson’s diseases, Dr. Oz says. “So there are a bunch of different places where coffee can play a role. The reason it got a bad name is because it does have side effects, for example, migraine headaches and heart palpitations. But if you’re not having them, coffee is reasonable.”

Did we mention, it’s good for those bowel movements, too? Dr. Oz suggests 24 ounces of coffee a day is a rational amount for one person.

11. The calcium in milk is obviously good for bones — any man with a mother has heard that one. But the other important ingredient is vitamin D, which is a cancer-fighting agent. While your body can actually get this vital nutrient from the sun, if you live north of Los Angeles or Atlanta, you won’t get enough vitamin D in winter and you’ll need to supplement it. A glass of milk or fortified orange juice a day should do the trick.

A few weeks ago I was using my flat iron and when I looked in the mirror to admire my ’do, I discovered my first gray hair (gasp!). It was the first time I was visibly confronted with the reality that, surprise, I will age, and I’m not 18 anymore no matter how good I feel.

I already have the exercise part down, so on my quest for a fountain of youth I’m paying more attention to research on how to eat to age healthfully. The best information I’ve found? 7 anti-aging super foods and recipes to enjoy them in, from Peter Jaret’s James Beard Foundation award-winning article in EatingWell Magazine, “The Search for the Anti-Aging Diet.”

Read on to find out more about the 7 foods to keep you young:

Chocolate
The Kuna people of the San Blas islands, off the coast of Panama, have a rate of heart disease that is nine times less than that of mainland Panamanians. The reason? The Kuna drink plenty of a beverage made with generous proportions of cocoa, which is unusually rich in flavanols that help preserve the healthy function of blood vessels. Maintaining youthful blood vessels lowers risk of high blood pressure, type 2 diabetes, kidney disease and dementia.

Blueberries
In a landmark study published in 1999, researchers at Tufts University’s Jean Mayer Human Nutrition Research Center on Aging fed rats blueberry extract for a period of time that in “rat lives” is equivalent to 10 human years. These rats outperformed rats fed regular chow on tests of balance and coordination when they reached old age. Compounds in blueberries (and other berries) mitigate inflammation and oxidative damage, which are associated with age-related deficits in memory and motor function. Eat more blueberries with healthy blueberry recipes.

Fish
Thirty years ago, researchers began to study why the native Inuits of Alaska were remarkably free of heart disease. The reason, scientists now think, is the extraordinary amount of fish they consume. Fish is an abundant source of omega-3 fats, which help prevent cholesterol buildup in arteries and protect against abnormal heart rhythms. Eat some tonight with a healthy fish recipe.

Nuts
Studies of Seventh-Day Adventists (a religious denomination that emphasizes healthy living and a vegetarian diet) show that those who eat nuts gain, on average, an extra two and a half years. Nuts are rich sources of unsaturated fats, so they offer benefits similar to those associated with olive oil. They’re also concentrated sources of vitamins, minerals and other phytochemicals, including antioxidants.

Wine
Drinking alcohol in moderation protects against heart disease, diabetes and age-related memory loss. Any kind of alcoholic beverage seems to provide such benefits, but red wine has been the focus of much of the research. Red wine contains resveratrol, a compound that likely contributes to its benefits-and, according to animal studies, may activate genes that slow cellular aging.

Olive Oil
Four decades ago, researchers from the Seven Countries Study concluded that the monounsaturated fats in olive oil were largely responsible for the low rates of heart disease and cancer on the Greek island of Crete. Now we know that olive oil also contains polyphenols, powerful antioxidants that may help prevent age-related diseases.

Yogurt
In the 1970s, Soviet Georgia was rumored to have more centenarians per capita than any other country. Reports at the time claimed that the secret of their long lives was yogurt, a food ubiquitous in their diets. While the age-defying powers of yogurt never have been proved directly, yogurt is rich in calcium, which helps stave off osteoporosis and contains “good bacteria” that help maintain gut health and diminish the incidence of age-related intestinal illness.
