The document discusses vitamins A and D. It explains that vitamin A is a fat-soluble vitamin found in both animal sources like eggs, cheese and liver as well as plant sources like carrots, sweet potatoes and spinach. Vitamin A supports vision, bone growth, reproduction and immune function. Vitamin D is also fat-soluble and obtained through fatty fish, fortified milk, egg yolks and sunlight. Vitamin D aids in calcium and phosphorus absorption to support bone and teeth health. Deficiencies in vitamins A and D can lead to conditions like night blindness and rickets, while too much can be toxic.
