As an answer, first we need to understand the harm of haze on the human body. Haze is mainly composed of fine particulate matter and harmful gases, prolonged exposure to the haze environment will be a potential threat to the respiratory system, cardiovascular system and immune system and other health. Therefore, choosing the right food can play a protective role in hazy weather.

Let's look at some foods that can help ward off damage from the haze. The first recommendation is foods rich in vitamin C, such as citrus fruits, fresh orange juice and tomatoes. Vitamin C has an antioxidant effect that can help remove free radicals from the body and strengthen the body's resistance.

Secondly, it is foods rich in beta-carotene, such as carrots, pumpkin, red peppers, etc. Beta-carotene is a good antioxidant, which can reduce the damage of the haze on the skin and respiratory tract.

It is also recommended to consume foods rich in vitamin E, such as vegetable oils, nuts and cod. Vitamin E has antioxidant properties that can reduce damage to the lungs and respiratory tract from the haze.

For hazy weather can also moderate intake of food rich in dietary fiber, such as whole grains, grains, fruits and vegetables. Dietary fiber can help remove harmful substances from the body and promote detoxification and intestinal health.

Drinking more water in foggy weather is also very important. Adequate water can dilute the concentration of harmful substances in the body and promote elimination.

In haze weather, a reasonable choice of food can help us better resist haze damage. Appropriate intake of foods rich in vitamin C, β-carotene, vitamin E and dietary fiber, and maintain adequate water intake, can help to strengthen the body's resistance to reduce the impact of haze on health. It should be noted, however, that you can't rely on food alone to ward off haze damage; you should also take other effective protective measures, such as wearing a mask and reducing outdoor activities.

I hope the above information is helpful to you!
