Stomach irritation
Nuts contain a compound called phytic acid. For some people, phytic acid irritates the digestive system. To break down phytic acid, you need the enzyme phytase, but your body doesn't produce it on its own.
Therefore, keeping track of your body's symptoms can help you identify which nuts are not suitable for your body.
Food intolerance
A true nut allergy is more likely to cause symptoms such as wheezing or coughing, hives, or a swollen tongue. Your condition may be due to a food intolerance.
If you have a nut intolerance, you may experience symptoms 1-4 hours after eating. In addition to stomach pain, you may also experience headaches and nausea.
Bloating and flatulence
Nuts are high in fiber. Fiber can help normalize bowel movements and promote gut health.
However, if your body isn't used to eating a lot of nutrients, high-fiber snacks like nuts can lead to gas and bloating.
To avoid this problem, you should slowly add fiber-rich foods like nuts to your diet over a few weeks to give your body time to adjust, according to the Mayo Clinic.
