Final Thoughts

Consuming healthy foods alongside antibiotics is important for keeping your digestive system healthy and aiding your recovery. Probiotics, prebiotics, protein sources, fruits, vegetables, and whole grains are generally healthy food options for most individuals. However, some foods may interact with certain antibiotics, such as grapefruit and dairy products. You should always check the instructions for your medications and consult your physician or pharmacist if you have any questions regarding possible food interactions.
