What type of substance in food can irritate pores when excreted?

1. Sugars

2. Salt

3. Iodides

4. Carbohydrates

The correct answer is: Iodides

Iodides are known to have an effect on the skin, particularly in terms of potentially irritating the pores. When consumed, iodides can be excreted through the skin, and for some individuals, this can lead to irritation or exacerbation of conditions like acne. The presence of iodides can stimulate sebaceous glands and lead to an increased production of oil, which may clog pores and result in breakouts or irritation. While sugars, salt, and carbohydrates can also have effects on skin health, they do not specifically lead to pore irritation in the same direct manner as iodides. Sugars have been linked to glycation processes that can affect skin aging and health, salt can cause dehydration and puffiness, and carbohydrates, especially in high quantities, may influence insulin levels which can in turn affect skin condition. However, the unique connection of iodides with pore irritation through excretion makes it the correct answer.
