Caloric Overload: Excessive walnut consumption can lead to a surplus of calories, potentially contributing to weight gain and associated health issues.
Omega-6 Fatty Acids Imbalance: While walnuts are rich in omega-3 fatty acids, an excessive intake may disrupt the balance with omega-6 fatty acids, potentially promoting inflammation.
Digestive Issues: The high fiber content in walnuts can cause digestive discomfort, including bloating and gas, when consumed excessively.
Allergic Reactions: Some individuals may be allergic to walnuts, and overconsumption can heighten the risk of allergic reactions, ranging from mild itching to severe anaphylaxis.
Oxalate Accumulation: Walnuts contain oxalates, and excessive intake may contribute to the formation of kidney stones in susceptible individuals.
Phytic Acid Content: Walnuts contain phytic acid, which can bind to minerals and reduce their absorption. Excessive consumption might impact mineral availability in the body.
Potential for Weight Gain: Despite their health benefits, the calorie density of walnuts may contribute to weight gain if consumed in excess without compensating adjustments to overall caloric intake.
Interaction with Medications: Walnuts can interact with certain medications, such as anticoagulants, potentially affecting blood clotting. Excessive consumption may amplify these effects and pose health risks.
