03 Sep 2019 --- The plant-based diet has been hailed for both its health halo and positive environmental impact, but a nutritionist has warned that it may risk worsening deficiencies in a key nutrient – choline. Calls for a move to plant-based diets are increasing in the name of the planet and our health. But now, Dr. Emma Derbyshire, of Nutritional Insight, a consultancy company specializing in nutrition and biomedical science, says that those moving to such a diet must carefully monitor their choline intake. The way that the mainstream media has jumped on her findings and “over-exaggerated them” in recent days illustrates the lack of understanding around choline, she tells NutritionInsight.
