For grown-ups. Fold this page away before handing over the rest.

Obesity, tooth decay, and heart problems · Sugar feeds tooth decay. Extra food energy can cause weight gain. Too much saturated fat raises the risk of heart problems.
Your heart, lungs, and muscles · Exercise makes your heart pump better, your lungs work harder, and your muscles grow stronger, all at once.
True · Smoking harms your lungs directly and also makes heart disease more likely.
The sugar in her sweets · The sugar in sweets feeds tooth-decay germs. The lesson links excess saturated fat to heart risk, not to feeding those germs.
1 · The chart shows about 1 hour of exercise. That daily movement helps make your heart, lungs, and muscles stronger.
His liver · The liver breaks down alcohol. Regularly drinking too much can damage it.
Vegetables do not cancel out too much sugar · A healthy food doesn't undo a poor one. Too much sugar can still lead to tooth decay, extra weight, and heart problems.
Omar, the heart and lungs strengthen too · Exercise does more than build muscle. It also makes the heart pump better and the lungs work more efficiently.
