Joining us today is dietitian Sinead O'Donovan, who spends a lot of time helping people separate nutrition facts from social media fiction.  

   Because if you’ve spent more than five minutes on TikTok lately, you’ve probably been told seed oils are ruining your life,  and some influencer is selling a supplement that supposedly “melts fat” overnight.  

   With so much conflicting advice online, it can be really hard to know who or what to trust when it comes to food, dieting and health.
