Frequently Asked Questions:

5 FAQs About Peanut Butter and Digestion

1. I love peanut butter, but I also get frequent heartburn. Should I avoid it completely? 

Not necessarily! While peanut butter can trigger heartburn in some people, it's often a matter of moderation and preparation. Try consuming smaller portions, choosing natural peanut butter with no added sugar or oils, and pairing it with less fatty foods. If your heartburn persists, consider a food sensitivity test to rule out a peanut intolerance.

Yes, the fiber content in peanut butter can help promote regularity and ease constipation. However, excessive intake might lead to loose stools or diarrhea in some individuals, so it's best to consume it in moderation.

3. What are some healthier ways to enjoy peanut butter? 

Instead of reaching for a spoonful straight from the jar, try incorporating peanut butter into a balanced meal or snack. Spread it on whole-grain toast, add it to smoothies, or pair it with apple slices or celery sticks for a fiber-rich and satisfying snack.

If your symptoms are primarily digestive, like stomach pain or diarrhea, a food sensitivity test can help determine if you have an intolerance to peanuts.
