When patients have gingivitis, it is generally advised not to eat lamb. Because lamb is considered a heat-inducing food, and the inflammation in the patient's body is often caused by excessive internal heat. Eating lamb in such cases could potentially exacerbate the condition, making the symptoms more severe. It is suggested that patients can eat some chicken, duck, or fish instead, as these high-quality protein sources are good choices for the body. Additionally, it is important to keep the diet light and avoid spicy and irritating foods. Try to avoid foods that can cause internal heat, such as lychee or durian, which are considered heat-inducing fruits. It's appropriate to consume some kiwi and dragon fruit, which can provide a substantial amount of vitamins and also help in the repair of teeth.
