Why do raw macadamia nuts make you vomit?

Raw macadamia nuts contain certain compounds, such as cyanogenic glycosides, that can be toxic when consumed in large amounts. These compounds can lead to gastrointestinal distress and may cause symptoms like nausea and vomiting. Additionally, the high-fat content of macadamia nuts can be difficult to digest for some individuals, further contributing to these adverse effects. It's generally safer to consume roasted macadamia nuts, as the roasting process reduces these compounds.
