Nowadays there are more dusts in the air because there are more and more cars and factories in the world now. The dust of the air is the main cause of the fog and haze. The particles whose aerodynamic diameter is larger than ten micron could be intercepted by the cilia in the nasal cavity when it gets into our body through our nose. However, the particles with smaller aerodynamic diameters can easily get into our bodies through our nose. We also call them PM 10. If the particles’ aerodynamic diameter is smaller than 2.5 micron, the particles can get into our lungs’ bronchiole and deposit there. These depositions will affect the gas exchange in the lung and then may cause respiratory disease even lung cancer. The particles with aerodynamic diameter which is smaller than 0.1 micron can even get into our blood to cause some diseases about vessel.

Can food help us clean the dusts in our bodies? These dust particles influence our body through physical interactions so if we want to clean them, we should make the “cleaner” meet the particles. The foods get ion our body through digestive tract and they are digested into smaller molecules and get into blood. At last, the small molecules arrive at cells throughout our bodies. As a result of that, the foods’ molecules can meet with the particles whose aerodynamic diameter is larger than 0.1 micron. However, the small particles are huge to the foods’ small molecules. So we should carefully select the food that can help us clean the particles in our bodies.

The record in Chinese medical books says that the pears have the effects of helping us clean the lung. The glycoside and tannin in pear can clear the lung, relieve the cough, reduce phlegm and nourish the blood. The Canned Diced Pear with white sugar has great effect on cleaning the small particles in our bodies.

Nowadays, our work and life are very busy and sometimes we go outside. Canned pear in syrup is a very portal way to have pears which can help us clear the dusts in our bodies. You are able to take them with you and keep for a long time.
