We chose Dr Chan as our nutrition expert because of her keen interest in women's and children's health issues.
As well as writing four books on nutrition, she's written for women's magazines including Woman, Best, Top Sante and Our Baby. Wynnie has appeared on numerous TV and radio shows as a consultant on a variety of nutrition-related issues. But, it's not all glamour - the doctor was instrumental in creating the UK food tables, which give the complete nutritional composition of thousands of foods.
