Prebiotics' Role in Treating Lactose Intolerance — What Dietitians Need to Know By Constance Brown-Riggs, MSEd, RD, CDE, CDN Today's Dietitian Vol. 19, No. 7, P. 18 Link

Probiotics are available in dietary supplements and yogurts, as well as in suppositories and creams.4 The FDA defines yogurt as a fermented dairy product derived from the fermentation of milk by two species of bacterial cultures: Streptococcus thermophilus and Lactobacillus bulgaricus.10 "The two starter cultures [S thermophilus and L bulgaricus] used to make yogurt produce β-galactosidase, which aides in lactose digestion in the gut," says Jo Ann Hattner, MPH, RDN, of Hattner Nutrition in San Francisco and coauthor of Gut Insight: Probiotics and Prebiotics for Digestive Health and Well-Being. "That's why people who are lactose intolerant can often tolerate eating yogurt more than drinking milk," Hattner says.

Welcome to the World in Your Gut. By Melissa Pandika | June 20, 2016 | Rally Health Link

Hattner interview excerpt:

When it comes to supplements, buyer beware. It’s unclear whether supplements work as well as probiotics in food. But since supplements don’t fall under FDA regulation, they “can be very concerning to someone with serious health conditions,” says Hattner. They can also be pricey, and “what’s on the label might not necessarily be what’s in the product.” For instance, a supplement label might state that the product contains 10 billion cultures — but they might be freeze-dried, and only a small fraction may “wake up” in the body.

Think about prebiotics. Probiotics alone may not be enough — “you have to feed them,” Hattner says. Called “prebiotics,” the food for probiotics is mainly fiber. Plus, research has already linked a high-fiber diet to a host of health benefits, including lower cholesterol levels, better control of blood sugar levels, and more regular bowel movements. Some examples of prebiotic-rich foods include garlic, onions, leeks, bananas, whole grains and flaxseed.

UCSF scientists declare war on sugar in food 2/2/12 Link

‎"When you get into this argument about sugar in the diet, you also have to look at the type of food that has a high sugar content," said Jo Ann Hattner, a San Francisco registered dietitian who teaches nutrition courses at Stanford. "Those foods have few nutrients and little fiber, and that's not good for you. So is it sugar itself that's harmful?" That said, Hattner added, there's no doubt that people in general consume too much sugar and that everyone could benefit from eating less - and especially looking out for "hidden" sugars in their diets.

What If I Ate Only One Type of Food? by Natalie Wolchover, Life's Little Mysteries Staff Writer. 27 January 2012 Link

"... what would actually happen if you ate only one type of food for your entire life? Depends on the poison you pick, but poison it most likely would be. According to Jo Ann Hattner... choosing to eat only one fruit, vegetable or grain would lead to organ failure. Consuming only meat would eventually force your body to start munching on your own muscles. And if you stuck solely to almost any one food (besides fruit), you would develop a serious case of scurvy."


Winter brings more than its share of cold and flu viruses. The average young person gets anywhere from 6 to 10 colds a year, and the dry heat of winter air and close proximity to others means it is easier to spread those nasty germs. Instead of heading to the medicine cabinet, try the kitchen cabinet to find foods rich in the nutrients that keep your immune system strong all winter long.
Probiotic foods (those foods that contain good bacteria for a healthy gut) can enhance immunity. Your guts contain 2 to 3 pounds of bacteria and emerging research shows that the type of bacteria that live in your gastrointestinal tract can prevent disease by acting as a natural antibiotic. Registered dietitian Jo Ann Hattner, author of Gut Insight ( points out that 70% of our immune function takes place in the gut so eating foods rich in probiotics is a good idea to stay healthy.

Sticky fingers among dietitians' pet peeves by Sheah Rarback, Miami Herald.

We all have pet peeves, and some are profession-specific. You might be surprised to learn what raises a dietitian's hackles. We don't jump in front of strangers at the grocery store and demand they remove the triple-fat cupcakes from their cart or stealthily replace their white bread with whole wheat. But that's not to say we don't have our supermarket triggers. San Francisco dietitian Jo Ann Hattner, author of Gut Insight ( hates to see people pick through fruit, then toss back and bruise the pieces they don't want. Appearance aside, bruised fruit with broken skin can make a more attractive home for bacteria, though it's generally safe to eat. (Just cut off the brown spots, chop the unblemished fruit and add it to a salad).
