We’ve all heard the age-old maxim: “prevention is better than cure” – advice that comes into its own when talking about health. According to World Health Organisation (WHO) data, obesity rates worldwide have increased threefold since 1975, with more than 340 million children (5-19 years) being classed as either overweight or obese. Studies have shown that healthy nutrition and improved lifestyle choices are effective preventative techniques that can significantly decrease waist circumference and BMI. With obesity increasing the risk of countless health conditions, including type 2 diabetes and heart disease, it is essential that doctors are at the frontline of this battle. They need to be armed with the knowledge and training to recognise nutrition- related diseases.
