New Study: Is Having a Dog Good for Your Gut Bacteria?

woman_kissing_dogThe question is one researchers from the University of Arizona hope to answer after an upcoming study, in which human participants will be paired with canine companions to determine the effects of the relationship on the bacterial population in the digestive tract.

Previous studies have linked dog ownership with better heart health and reduced stress, but anthropology doctoral student and study author Kim Kelly wants to delve more deeply into the story. The three-month study, a joint effort between the university and the Humane Society of Southern California, will examine whether or not living with a dog encourages the growth of beneficial bacteria in the human gut and whether it is enough to provide substantial physical and mental health benefits.

Researchers are currently recruiting adults 50 or over who are in good health. They will provide each adult with a dog and measure the gut bacteria levels of both at the beginning and the end of the study (as well as at the one- and two-month marks) in order to determine whether or not the relationship has had a positive impact on the gut microflora of either party.

Interestingly, earlier studies have shown that the longer they live together, dog owners and their companions tend to share a lot of the same gut bacteria—in large part because of all those wet, slobbery kisses. Kelly and her team hope to understand more about the relationship and its potential benefits, such as improved digestion and immune function.

Good Nutrition for Kids and 3 Benefits of Probiotics

girl_w_tomatoesNowadays teaching our children about good nutrition is more important than ever, especially since many kids fall short when it comes to getting the essential nutrients their growing bodies need. Several recent studies about kids’ health have warned parents about the dangers of too much sugar and not enough fiber in the diet, pointing out that such eating habits can significantly impact their health in the long run.

Up to 80% of the immune system is found in and around the digestive tract, but a high-sugar, low-fiber diet can deplete the amount of good bacteria in your child’s gut. This can lead to occasional tummy upset, poor digestion, and a decrease in healthy immune function. Probiotic supplements for kids are a safe and gentle way to help replenish the balance of good bacteria in the digestive tract and support the developing immune system.‡ Below are three key benefits of adding a daily probiotic to your child’s diet:

  1. Healthy Immune Function‡ Added beneficial bacteria support a healthy digestive balance and help teach the immune system to respond appropriately to outside challenges.‡
  2. Regular Bowel Movements‡ Regular elimination needs a healthy balance of good bacteria in the gut. Daily probiotics have been shown to help support that balance, which in turn promotes regularity and helps prevent the occasional upset tummy.‡
  3. Healthy Digestion‡ In addition to producing vitamins—including important B vitamins—probiotics produce digestive enzymes and support regular, balanced digestion.‡
