Question

Quizplus · Accepted Answer

Phytates and oxalic acid are both compounds found in plants and eggs that bind tightly to iron and limit its absorption. Solanine and cyanide are not typically found in significant amounts in plants and eggs, and cyanide can actually enhance iron absorption in small quantities. Phytates and oxalic acid are commonly found in plant-based foods such as grains, legumes, and spinach, which is why it is important to consume a variety of foods to ensure adequate iron intake.
