Which fruit juices can relieve thirst and stimulate saliva production?

Generally, fruit juices such as watermelon juice, pear juice, orange juice, grape juice, and pomelo juice can help relieve thirst and stimulate saliva production. Detailed explanations are as follows:

1. Watermelon juice: Watermelon contains an extremely high water content. When juiced, it has a sweet and refreshing taste, and drinking it can quickly replenish body fluids. Additionally, the various vitamins it contains can stimulate saliva secretion, alleviate dry mouth, and thus relieve thirst.

2. Pear juice: Pears are cool in nature and rich in water. The resulting juice is light and refreshing, which can moisturize the throat and oral mucosa, reduce dryness, and promote salivary gland secretion, effectively alleviating thirst and stimulating saliva production.

3. Orange juice: Rich in vitamin C and water, orange juice has a sweet and sour taste that stimulates the taste nerves and promotes saliva secretion when consumed. It also replenishes lost fluids and nutrients, helping to relieve thirst and stimulate saliva production.

4. Grape juice: Containing abundant water and carbohydrates, grape juice is sweet and can quickly relieve thirst caused by dehydration. Its nutritional components also help regulate bodily functions and promote saliva secretion, achieving the effect of relieving thirst.

5. Pomelo juice: Pomelo juice has a balanced sweet and sour flavor and is rich in water. Drinking it can moisturize the mouth, stimulate saliva secretion, alleviate dry mouth, and its various components help maintain the body's fluid balance, effectively relieving thirst.

When consuming these juices to relieve thirst and stimulate saliva production, it is recommended to choose freshly squeezed juice without excessive added sugar. Consumption should also be moderate to avoid overburdening the gastrointestinal tract.
