My sport loving 14 year old son Hamish, has decided he wants to get strong and put some bumps on his sticks (he's tall and lean) ;). Thank goodness he also started to realise all the carbs he was eating were not helping, making his energy spike then crash, and him grumpy! Hamish was looking for a pre match smoothie, so we played with what ingredients he loves and created a delicious and supercharged smoothie that he now requests all the time! I suggest starting with a smoothie based on your teenager's favourite ingredients, then slowly decrease the sugary ingredients and add some you know are extra nutritious. I've given some suggestions below. Teenagers usually burn off more carbs than us, so you will see there are three serves of carbs in this smoothie rather than the one in my Superhuman Smoothie. If you're making a post game smoothie, I recommend leaving out the oats, as the focus is more protein for recovery. I'd love your feedback and suggestions of what you put in your kids and teenagers smoothies.
