Globally, 41 million kids under the age of five are overweight, and another 159 million kids are malnourished. Something has to change. For over 15 years, culinary hero and food activist Chef Jamie Oliver has been campaigning for better food and health with a goal to improve global child health.

May 20th marks the third annual Food Revolution Day. The Food Revolution is an ongoing global campaign to improve child health by inspiring positive, meaningful change in the way our kids access, consume and understand food. And it all starts with good, fresh, real food.

Here are five simple things you can do today to build a healthy and happy generation for tomorrow:

1. Cook together! Chef and TV personality Guy Fieri says it best, “Cooking with kids is not just about ingredients, recipes and cooking. It’s about harnessing imagination, empowerment and creativity.” Cooking is a life skill.

2. Explore with food. Talk to the farmers at the local farmers’ market. Take the kids grocery shopping to see the variety of produce available all year long. Grow your own veggies. Plan a family outing at a pick-your-own berry or apple farm. Spend a day at the Royal Agricultural Winter Fair. Watch cooking shows together (MasterChef Junior, anyone?)!

3. Make a family cookbook. Go online, look at recipe apps, dust off your cookbooks and magazines. Try new foods and flavours. Put your favourites into a family cookbook – what a perfect holiday gift for friends and family!

4. Sign the Ontario Home Economics Association petition which urges the government of Ontario to make at least one food and nutrition course compulsory in high school. In Japan, cooking classes are mandatory in grades 5 to 12 – and could it be a coincidence that the Japanese have one of the lowest rates of obesity?

5. Sign up for Jamie’s Food Revolution. Starting at 10 am BST (UK time) or 5 am EST on Friday, May 20, watch live videos on Jamie’s Facebook page where you’ll see him dishing up advice and starring in cooking videos.
