Sarbjeet Singh is the Senior Content Manager and lead nutrition researcher at DietXP. He came to nutrition from pharmacy: a B.Pharm from Gurukula Kangri Vishwavidyalaya, an MSc in Chemistry from North Eastern Hill University, and registration with the Uttar Pradesh Pharmacy Council, followed by an MSc in Dietetics and Food Service Management (2025). That mix means he reads a nutrition claim the way a pharmacist reads a drug label: mechanism, dose and evidence first.
In 2025 he completed a clinical observership in the Department of Digestive Disease and Clinical Nutrition at Tata Memorial Hospital, Mumbai, and co-authored a retrospective cohort study of 1,922 oesophageal cancer patients published in Clinical Nutrition ESPEN. He holds the ESPEN certificate in oral and enteral nutrition for adults and the Monash University Low FODMAP certificate, and is a certified diabetic educator.
At DietXP he sets the editorial direction, writes the Knowledge Hub guides and checks every article before it is published. He has written more than 100 researched articles on nutrition, preventive health and lifestyle medicine, including all of DietXP's thyroid and vitamin B12 guides. Before DietXP he taught chemistry and STEM at Cambridge-curriculum schools for six years and worked in key account management at Abbott Healthcare.
