Dr Soumyadeep Bhaumik

Profile

Dr. Soumyadeep Bhaumik is a medical doctor and international public health research methodologist striving to harness the power of science to drive just transformation for healthier individuals, communities, and nations.

As the Head of the Meta-research and Evidence Synthesis Unit at The George Institute for Global Health, he oversees an agile global team of researchers, specialising in using fit-for-purpose approaches for synthesising evidence to inform policies, practices, and guidelines. He is recognised internationally for his work on evidence synthesis, particularly research priority setting and core outcome sets - both its conduct and methodological aspects. He also works on the moral and epistemological aspects of meta-research in health and medicine with the intent to transform the evidence ecosystem from justice-blind to pro-justice. Soumyadeep also conducts interpretive policy analysis to understand the societal construction and framing of public health problems. As a methodologist, he works in a disease-agnostic manner, although recent work has had a focus on snakebite.

Soumyadeep' s work has impacted the way research is conducted -through the Cochrane Handbook Chapter, which provides guidance on framing the scope of systematic reviews, development of reporting guidelines for research, and through methodological research. His work routinely influences guidelines, and policies of governments and multi-laterals. They have consistently been listed as one of the top 2% lifetime cited researchers (Stanford University analysis in General & Internal Medicine and Public Health field) since 2021.

‘Low sugar’, ‘low carb’, ‘healthy choice’: how the alcohol industry is marketing its way into your wellness routine

News / Media release 03 Mar 2026

Added sugar

Australians consume around 14 teaspoons of added sugar a day - two more than the 12 teaspoons limit recommended by the World Health Organisation (WHO). Eating too many foods high in added sugars can lead to weight gain, an increased risk of obesity related diseases, and is a major risk factor in tooth decay. What is sugar? Sugar is a type of carbohydrate that occurs naturally in foods such as milk and fruit and can also be added to foods and drinks in various forms by the manufacturer or the consumer. Total sugars of a product refers to the combination of sugars that are naturally present and those that are added.Intrinsic and milk sugars occur in foods and drinks such as intact fruits and vegetables (i.e. fructose) and milk (i.e. lactose).Added sugars are all other sugars. It is these sugars that are associated with poor health outcomes and we should avoid. They are often added by manufacturers to give greater sweetness or other desired characteristics.
