Question: Can eating probiotics and/or prebiotics give me more energy during the day?

Answer: There is nothing in particular about probiotics or prebiotics that will give you energy. However, one of the best probiotic-rich foods, yogurt, is an excellent source of lean protein and calcium. Prebiotic foods are a great source of vitamins, minerals, and other nutrients that give you the energy you need to get through the day. Prebiotic-rich foods include whole grains, onions, bananas, garlic, honey, and artichokes.

Question: Can the probiotics in yogurt help relieve my diarrhea?

Answer: Eating yogurt may help with certain types of diarrhea. By replenishing the good bacteria that may have been lost, yogurt can help bring the bad bacteria back in balance. However, if you have fever, abdominal pain or swelling, or your diarrhea lasts more than a couple of days, you should see your doctor.

Question: What are the disadvantages of not getting enough prebiotics in your diet?

Answer: Prebiotics help nourish the probiotics in your intestines. You need a healthy amount of probiotics in your intestines to help keep your digestive system in balance. If you don’t eat foods rich in prebiotics, the level of probiotics may fall. While it’s unclear exactly what effect that may have on any individual, we do know that it’s important to keep the right balance between good and harmful bacteria.

Question: Can adding prebiotics to my diet benefit my baby and me in any way while I'm breastfeeding?

Answer: It’s a good idea to make foods rich in probiotics and prebiotics a part of your healthy diet. In addition to any potential benefit you get from probiotics, many of the foods are sources of other healthy nutrients. Healthy bacteria, especially lactobacillus, are found in breast milk. So eating foods rich in probiotics can help support a healthy digestive and immune system for both you and your baby. There is even some evidence that eating a diet rich in probiotics may help calm colic in babies, but it’s too early to know for sure.
