1. Allergies: Some people may be allergic to tiger nuts. Symptoms of a tiger nut allergy can range from mild (itching, hives) to severe (anaphylaxis).
2. Digestive Issues: Tiger nuts are high in fiber, which can cause digestive issues like bloating, gas, and diarrhea in some people, especially if they are not used to eating a high-fiber diet.
3. Fungal Contamination: Tiger nuts can be contaminated with fungi, especially if they are not stored properly. This can lead to food poisoning, with symptoms like nausea, vomiting, and diarrhea.
4. Interaction with Medications: There is some evidence that tiger nuts may interact with certain medications, such as blood thinners. If you are taking any medications, it is important to talk to your doctor before adding tiger nuts to your diet.
5. Oxalates: Tiger nuts contain oxalates, which can contribute to kidney stones in some people. However, this is generally not a concern for most people who eat tiger nuts in moderation.
6. Contamination with other nuts: Tiger nuts are not true nuts, but they are often processed in facilities that also handle nuts. This means that there is a small risk of cross-contamination with other nuts for people with nut allergies.
It's always best to talk to your doctor or a registered dietitian before adding any new food to your diet, especially if you have any pre-existing medical conditions.
