Final answer:
To prevent rickets, vegetarian children need to ensure they get enough vitamin D and calcium. Vitamin D is crucial for the absorption of calcium for healthy bones and can be obtained from sunlight exposure, fortified foods, or supplements.
Step-by-step explanation:
To prevent rickets, vegetarian children should be sure to obtain sufficient amounts of vitamin D and calcium. Rickets is a condition that results in improper bone development in children due to the malabsorption of calcium and a deficiency in vitamin D. This vitamin is essential for the normal absorption of calcium and phosphorous, which are critical for healthy bones. Vitamin D can be synthesized in the skin upon exposure to UV radiation from sunlight, with further conversions taking place in the liver and kidneys. While vitamin D is not found naturally in many foods, it is often added as a supplement to items like milk and orange juice. Furthermore, for those who do not receive adequate sunlight or dietary vitamin D, a supplement may be necessary. It is important for vegetarian children, in particular, to ensure they are receiving enough vitamin D, whether through fortified foods, supplements, or safe sun exposure, to maintain proper bone health and prevent rickets.
