Patients with rickets should not eat some cereal foods, such as millet, rice, wheat, corn, and other foods. Cereal foods also contain vitamin D and calcium, and eating too much of these foods can exacerbate the disease. Patients with rickets should eat more light, low-fat, and easily digestible foods. They should control the intake of high-fat content daily and avoid eating stimulating and spicy foods. At the same time, they should increase their intake of vitamins, encourage the child to eat more fruits and vegetables to ensure an adequate supply of vitamins, and patients can also exercise more. More physical activity can help boost the immune system.
