#What you see is very scientific#

There are many little knowledges in life, although it seems trivial, but mastering this knowledge can make our life healthier, safer and more convenient. The following are some common knowledge in life sciences:

1. Diet

Breakfast is most important meal of day. Eating breakfast can supplement energy and nutrients needed by body, increase body's resistance, improve concentration and work efficiency.

When eating fruits, it is better not to remove peel. The skin of many fruits is rich in nutrients and fiber, and peeling skin will reduce nutritional value of fruit.

Green journey. Green travel refers to choice of environmentally friendly means of transport such as public transport, cycling, walking, etc. It is recommended to choose greenest way of travel as possible to reduce pollution and exercise.

The above are some life science tips to help you in life. By mastering this little knowledge, we can better protect our own health and safety and at same time do our part to protect environment.
