A person deficient in the visual pigment rhodopsin should be advised to take eat more:

Question

BlackTom AI · Accepted Answer

In this question we’re connecting a deficiency in rhodopsin, a visual pigment in the rods of the retina, with nutritional recommendations that support visual function.
Option 1: 'guava and banana' — while guava contains some vitamins, these fruits are not notably high in vitamin A precursors (beta-carotene) or retinol; they don’t best address rhodopsin synthesis. Banana is mainly a carbohydrate source with limited vitamin A activity.
Option 2: 'apple and grapes' — apples and grapes are rich in fiber and various micronutrients, but they are not standout sources of vitamin A precursors; this pairing wouldn’t efficiently support rhodopsin production.
Option 3: 'sweet potato and broccoli' — this is the strongest choice. Sweet potatoes are famously rich in beta-carotene, a precursor to vitamin A, which is essential for retinol production in the body and supports rhodopsin regeneration in low-light conditions. Broccoli provides additional carotenoids and nutrients that can contribute to overall vitamin A status.
Option 4: 'strawberries and potato' — strawberries don’t supply much beta-carotene or retinol, and while potatoes provide some nutrients, the combination does not optimally boost vitamin A levels needed for rhodopsin maintenance.
Overall, the reasoning centers on supplying the body with vitamin A precursors to support rhodopsin synthesis and function; among the options, sweet potato and broccoli best fulfill that need by offering high beta-carotene content and supportive nutrients.
