What is the potential effect of high doses of cyanogenic glycosides?

High doses of cyanogenic glycosides can lead to toxicity due to their ability to release cyanide when metabolized. Cyanogenic glycosides are compounds found in certain plants, and when consumed in large amounts, they can pose serious health risks. The cyanide released interferes with the body's ability to utilize oxygen, effectively leading to cellular asphyxiation. This toxicity can cause symptoms such as headache, dizziness, nausea, respiratory distress, and in severe cases, can be fatal.

While other options may relate to potential symptoms or effects one might experience due to various health issues, the characteristic fundamental danger associated with high doses of cyanogenic glycosides is specifically toxicity resulting from cyanide release. This distinguishes it clearly from mere digestion issues or weight gain, which do not encompass the severity and immediacy of the harm posed by cyanogenic glycosides. Cardiac arrest may occur as a consequence of severe toxicity, but it is not the direct effect aptly describing the impact of high doses of cyanogenic glycosides.
