You're Feeling Sleepy

Getting enough sleep is one of the most important ways to maintain a healthy body. Your body does many important tasks during sleep. Your brain stores memories, which helps you think more clearly. Your body grows and repairs cells while sleeping. Your body also makes hormones during sleep, which affect your growth, metabolism, and mood. Sometimes people drink coffee or energy drinks as a method to increase their energy. However, this doesn’t replace the benefits of a nap or a good night’s sleep.

Many people, including teenagers, don’t get enough sleep. Teens should sleep about nine hours every night. There are many things that you can do to improve the quality of your sleep. Being active during the day makes you sleep better at night. In the evening, avoid caffeinated drinks such as coffee, energy drinks, hot chocolate, and colas. The bright light from digital screens stimulates the brain. Turning off digital devices an hour before going to bed can help you get to sleep faster.

Eating a Well-Balanced Diet

The human body needs a variety of nutrients to stay healthy. Three necessary nutrients for the human body are proteins, fats, and carbohydrates.

Your body needs proteins to build and repair tissues. Food from animals, like meat and dairy products, contain all the proteins your body needs. Plants contain proteins too, but vegetarians need to eat a wide variety of plant foods to get all the types of protein their bodies need.

Your body uses fats as insulation and to store energy for when you can’t eat immediately. Fats also help your body store essential vitamins. Eating too little or too much fat is not healthy for your body. Some fats are healthier than others. Examples of foods containing good fats are avocados, olives, nuts, and fish.

Your body uses carbohydrates for energy. Good sources of carbohydrates are found in whole grains and vegetables. Sugar and processed white grains contain high amounts of simple carbohydrates. If you eat too many simple carbohydrates, your body stores them as fat. Too much stored fat in the body can lead to a number of health problems.

Download:

DOWNLOAD the Canada Food Guide. This guide will help you with step 1 of this activity.

DOWNLOAD this document. It has a blank one-week meal plan chart that you can use for step 2 of this activity.

Instructions:

  1. You should have already downloaded the Canada Food Guide (CFG). Look at second page of the CFG very carefully, specifically the recommended number of servings per day of vegetables and fruit, grain products, milk and alternatives, and meat and alternatives. You should be able to tell from the chart how many servings of each food group are recommended for YOU.

  2. Now you get to plan your meals for one whole week!  Fill in the chart with healthy meals for each day. Your meal plan should contain at least 3 different breakfasts, 3 different lunches, 5 different suppers, and 4 different snacks. Fill in amounts or volumes of food on the chart as well. For example, you could indicate ½ cup of carrot sticks as a snack. Remember to use the Canada Food Guide from step 1 as a guide to make sure you are getting the number of servings from each food group that you need.


  3. If you had plenty of healthy meal ideas on your own, you can skip this step. But if you are struggling for healthy meal ideas, visit the following websites, they have some great tips and meals for healthy eating:
  1. Finished your meal plan for the week? Good! Now double-check it against the Canada Food Guide from step 1 to make sure you are getting all the servings you need from the different food groups.
