Chewing fennel seeds after a high-fat meal may help reduce bloating and gas and may support regular bowel movements.
You only need about ½ to 1 teaspoon of fennel seeds, and chewing them slowly may help you get the most benefit.
People who are allergic to fennel or related plants, are pregnant, or have certain hormone-sensitive health conditions should exercise caution and consult a healthcare professional before consuming fennel seeds regularly.
Fennel seeds provide a variety of nutrients and plant compounds and may be a useful post-meal addition for some people. Chewing fennel seeds after a meal may help ease bloating and gas, while their plant compounds may also have potential benefits for blood sugar regulation.
Fennel Seeds May Relax Your Intestinal Muscles
Oils and plant compounds found in fennel seeds may help relax the digestive tract, which could help reduce bloating and abdominal cramps.
“Fennel seeds relax intestinal smooth muscles, help improve gastric motility, and provide a good source of fiber that helps promote regular digestion,” Sara Wisehart, MS, RD, an Indianapolis-based dietitian and founder of Wiser Nutrition and Wellness, told Verywell. “Benefits may include reduction of gas pain, bloating, cramps, and reduction of constipation and diarrhea.”
