Junk Food - Unhealthy Fuel for your Body
Many teenagers eat junk food every day. This might be sugar-sweetened drinks like fizzy drinks and high-kilojoule snacks like potato chips. However, your body cannot run properly on poor fuel.
Compared to home-cooked food, junk food (which includes fast food) is almost always:
1. higher in fat, particularly saturated fat
2. higher in salt
3. higher in sugar
4. lower in fibre
5. lower in nutrients, such as calcium and iron
6. served in larger portions, which means more kilo joules.
While a mid-life heart attack might seem too far away to be real, it may surprise you to know that you could have health problems already. A poor diet can cause weight gain, high blood pressure, constipation, fatigue and concentration problems, even when you are young.
