The foods to eat for a healthy gut

4 foods to look for to keep your stomach lean, soothed'and even cancer-free
Our digestive systems continuously extract water and nutrients from an astonishing amount of solid foods and liquids over our lifetimes, all the while fending off nasty microbes and processing waste. What we put into our stomachs is so important that it affects whether we feel well, how flat our bellies are and even our chances of avoiding certain cancers.

When it comes to digestion, women face some unique concerns. ‘Shifting hormone levels from menstruation, pregnancy and menopause all put a feminine stamp on your digestive tract,’ says Dr. Cynthia Yoshida, a gastroenterologist in Charlottesville, Va., and co-author of No More Digestive Problems: The Answers Every Woman Needs. Anatomy also plays a role: Women have the same digestive organs as men, but they are squeezed, along with reproductive organs, into a smaller abdomen. ‘This means our digestive organs don’t have much give when they get filled with excess gas, air or food,’ she notes.


Keeping your stomach healthy, soothed and lean can be as simple as making the right food and drink choices. Here’s how!

1. Eat to beat disease: citrus fruit, fibre-rich foods, leafy greens and yellow vegetables
‘Strive to get 20 to 25 grams of fibre a day,’ says Yoshida. Why? For one thing, it may help protect against cancers. One 2007 study found that a high fibre intake was associated with a decreased risk for esophageal and gastric cancers. And citrus fruit appears to have a protective effect against stomach cancer, according to a survey of studies published in the March 2008 issue of Gastric Cancer.

‘ Fibre is important for our overall digestive health’particularly in preventing constipation’not just for cancer prevention. Whole grains, spinach, cauliflower, carrots, wheat bran, apples, broccoli, beans, figs and pears are all great fibre sources. ‘Start slowly, adding more fibre every few days, and drink lots of water. This will help prevent the gas, cramping and bloating that can occur if you add fibre too quickly,’ advises Yoshida.

‘ Recent studies suggest that eating light green, dark green and yellow-coloured vegetables help add up to a healthy stomach, too. These vegetables tend to be rich in carotene, vitamins C and E, and folate, which may help protect the stomach from cancer.

‘ Preliminary lab research shows that juices’cranberry and raspberry juices, for example’contain compounds called phenols that may prevent GI pathogens such as salmonella. And resveratrol, an antioxidant that is found in red wine, may zap stomach pathogens while leaving the healthy bacteria alone, according to a 2007 study from the University of Missouri’Columbia.

Try this: Eat more fibre-rich whole grains

Aim for at least three servings of a whole-wheat or whole-grain food per day to help boost fibre intake. A slice of bread or 30 grams (one ounce) of breakfast cereal makes one serving.

2. Help the good bugs: yogurt, sauerkraut, miso, bananas, garlic, asparagus, onions
About 100 trillion bacteria call your gut home’improve the ratio of good to bad bacteria by eating foods that contain probiotics (various types of healthy bacteria). Probiotics, which include lactobacilli and bifidobacteria, keep the lining of the colon healthy and may improve gut motility and sensation. While much of the research has centred on intestinal health, studies point to potential positive effects on the mouth and stomach, too.

‘ ‘The good bacteria in fermented foods like yogurt, miso and sauerkraut can make it through the gastric acid to the colon, where they go to work,’ says Yoshida. ‘There are some claims that the acid in your stomach kills the probiotic bacteria in food and that’s why you should take supplements instead, but that’s not true.’

‘ ‘In principle, there is no difference between probiotics taken as a supplement and those in food,’ says Michael Gänzle, Canada Research Chair in food microbiology and probiotics at the department of agriculture, food and nutritional science at the University of Alberta. ‘In practice, it is easier to keep high cell counts during the product’s shelf life if they are in a supplement.’ Experts recommend you use a product that contains one million to one billion live cultures. ‘But the market is unregulated; the consumer has to trust that the product contains live cultures that remain throughout the shelf life,’ explains Gänzle. ‘Try a product and see if you feel better. If you don’t, try another.’

‘ To support the growth of probiotic bacteria, also choose foods known as prebiotics that naturally contain lots of soluble fibre, such as bananas, garlic, asparagus, Jerusalem artichokes, honey, leeks and onions. Foods such as cheese and cereal bars that are labelled ‘prebiotic’ usually have added inulin, a soluble fibre most often extracted from chicory root.

3. Choose foods that soothe: caraway, cardamom, cinnamon, cumin, fennel, ginger, mint, nutmeg, oatmeal
‘Try foods called ‘carminatives’ that prevent or relieve gas, and are used to help the digestive process,’ says Jennifer Salib Huber, a registered dietitian and naturopathic doctor in Dartmouth, N.S. ‘Cumin, for example, helps with the digestion of black beans, which is why they’re often found in recipes together. Other carminatives include caraway, nutmeg, cinnamon and cardamom.’

‘ Ginger is a traditional nausea remedy, and new studies are backing up the claims. Research shows that it can help quell nausea due to pregnancy, chemotherapy and operations. A 2008 study published in the European Journal of Gastroenterology & Hepatology found that when healthy volunteers took ginger capsules along with a bowl of soup, their stomachs emptied more quickly. This may be useful for treating gastro-paresis, or delayed stomach emptying, a side effect of diabetes.

‘ ‘Oatmeal is a ‘demulcent,’ which means it gets slippery in water, helping to coat and soothe the stomach,’ says Salib Huber. Cooked oatmeal is your best bet, rather than cookies or granola bars where the oatmeal is dry.

‘ Peppermint leaf and oil have long been used to help relieve digestive disorders by relaxing stomach muscles. However, avoid peppermint if you’re prone to heartburn’those same relaxed muscles can allow more stomach acid to move up through the esophagus, says Yoshida. ‘The small amount of flavouring in mint gum or antacids shouldn’t cause problems,’ she adds.

Try this: Ginger 

To soothe motion sickness, chew a one-inch (2.5 cm) piece of peeled raw ginger, or candied ginger, several hours before’and every four hours during’travel.

4. Eat foods to flatten your tummy: avocado, brown rice, dark chocolate, nuts, oatmeal, olive oil, seeds
Choose foods from the Mediterranean diet‘lots of fruit, whole grains, vegetables, legumes, olive oil and low-fat cheese and yogurt; plus a moderate amount of fish, eggs, poultry, sweets and wine; and small amounts of meat. That, along with a daily exercise routine, will help you maintain a healthy body weight, advises Yoshida.

‘ ‘If you lose weight, your GI tract will feel better. Carrying less weight helps prevent abdominal discomfort‘that full, bloaty feeling’and acid reflux,’ says Yoshida. Extra abdominal pounds increase pressure on the lower esophageal sphincter, which separates the stomach from the esophagus. That pressure makes the valve open more often, allowing food and acid from the stomach to backwash into the esophagus, causing heartburn.

‘ Carrying excess fat in your midsection’even if your weight is within a normal range’puts you at risk for premature death, according to an American study of 44,636 women published in 2008. It concluded that women with a waist size of 35 inches (89 centimetres) or greater were twice as likely to die from heart disease and cancer, when compared to women with a waist size of less than 28 inches (71 centimetres). (To measure it, wrap the tape measure around your waist, above your belly button.) Belly fat can also boost your chances of developing chronic diseases such as diabetes and heart disease.

‘ Some foods may actually help target your tummy fat. A 2007 study published in Diabetes Care revealed that a diet rich in monounsaturated fats (MUFA), particularly olive oil, prevented fat from accumulating around the abdomen. Other sources of MUFA include avocados, olives, dark chocolate, sunflower oil, and nuts and seeds such as walnuts, flaxseeds and sunflower seeds. In a 12-week diet study, published in the American Journal of Clinical Nutrition in 2008, half of the obese participants ate whole-grain foods such as brown rice and oatmeal, and half ate refined grains such as white rice and bread. Both groups lost weight, but the whole-grain group lost significantly more abdominal fat.

Try this: Olive oil

Brush bread with olive oil instead of spreading with butter. You’ll consume about 50 fewer calories’and more healthy MUFA.
