“Dear Liz, Things are so simple for you growing up now. It’s going to be much harder for the next generation with the pressure they will face from social media. You are lucky, you have a cook-from-scratch diet of home cooking that features all the food groups, which will serve you well in the years to come and ensure you build healthy bones. Fast-food and things out of packets have yet to appear on your kitchen shelves – aside from Angel Delight (which I suggest you don’t get a taste for!). I know you love to dance – this is great! It’s a weight-bearing exercise that’s the other essential component in building strong bones. Your walk to school and college is also good for your bones too – and why not try a bit of running? You don’t fancy the idea now I know, but if you try it, you may well find you do actually like it after all (instead of discovering it in your fifties). Regarding eating well and taking exercise, my message to your bones is please don’t put it off! Leaving it late increases your risk of developing osteoporosis in later life – by the time you’re in your late twenties it will be too late to store any more calcium and build bone density. You will care about this when you’re older. Getting a little bit of sunshine is also important! You’ll grow up to be part of the beauty world that shuns the sun, but don’t lose sight of the fact that just ten or twenty minutes a day during the spring and summer months will help your body to produce vitamin D, an essential for healthy bones. Remember to take a note of those favourite family recipes we have – they’ll come in handy for your future work. Cooking and eating together is such a good and social way for families to build healthy habits – and you’ll want to pass that love of healthy food and wellbeing on to your own children too. And it will be even more important for your children than it is for you, as they face the pressure to match what their idols on Instagram are eating. This thing called ‘social media’ will cause a lot of confusion over what is ‘healthy’ and the next generation will need to get their understanding of the best nutrition from the wise who deliver good information and not just a pretty image on the screen.”

"My message to my younger self would be to have confidence in myself and not allow others to dictate what you should do. If you want to go down a road that may be different to the one your peers are travelling, don’t be scared or intimidated into not taking that path. This may be something as simple as wanting to play football or cricket as a girl, or as important as not to smoke or take drugs just because everyone else is. I wanted to be an actor and it was quite hard when I was a teenager to stick to my guns and try and do something which was quite out of the ordinary then. I wanted to do it so much that I dredged up the confidence from somewhere, even though I was quite shy and a bit too eager to please. Unfortunately there were a few other areas in which I wasn’t so single-minded! I definitely wish I’d never taken up smoking - I had to force myself to start, even though I initially hated it, largely because all my friends smoked. It took years to break the habit."

"Don't ever forget, what you do now will affect your bones in the future."
