## Question

Which one of the following is NOT a food rich in Vitamin A?

## Options

- **A.** Potato
- **B.** Squash
- **C.** Sweet potato
- **D.** Spinach

## Answer

Option A

## Explanation

Vitamin A content in foods: Vitamin A (retinol) is found in animal products directly, or as provitamin A carotenoids (especially $\beta$ -carotene) in plant foods. Vitamin A-rich foods: • Liver (beef, chicken): highest vitamin A content • Fortified dairy products • Egg yolk Beta-carotene-rich plants (converted to Vitamin A): • Sweet potato (orange-fleshed) • Carrots • Squash/pumpkin • Spinach, kale (dark leafy greens) NOT rich in Vitamin A: • Potato (white/yellow flesh): Very low in carotenoids; low in Vitamin A or $\beta$ -carotene. This distinction is important in understanding Golden Rice (engineered to contain $\beta$ -carotene to address Vitamin A deficiency in rice-eating populations, just as potato is also deficient). Answer: Potato is NOT rich in Vitamin A; Vitamin A-rich foods include sweet potato, carrots, spinach, and liver.
