Depending on the kind of study, here are some examples of the kind of things you might be asked
Metabolic tests: These could include measurements of weight, body mass index (BMI), waist circumference, or body composition (the percentages of fat, bone, and muscle in your body). More advanced metabolic tests might involve blood tests to assess levels of glucose, insulin, cholesterol, and other relevant metabolic markers.
Gut microbiome analysis: This usually involves providing a stool sample, which will be analysed to identify and quantify the various types of bacteria and other microorganisms present in your gut. This can give us valuable insights into the diversity and balance of your gut microbiome and how it might change in response to dietary interventions such as eating sourdough bread.
Blood sugar response tests: These typically involve measuring your blood sugar levels at various intervals after eating a specific food – in this case, sourdough bread. This can help us understand how your body metabolises the bread and what effect it might have on your blood sugar regulation.
Short-Chain Fatty Acids (SCFAs) analysis: SCFAs are the end products of the fermentation of dietary fibres by the gut microbiota, and they play a crucial role in maintaining gut health. A stool sample can be analysed to determine the levels of SCFAs, offering insights into how your diet, particularly the consumption of sourdough bread, may affect their production.
Dietary and lifestyle surveys: Participants might be asked to complete questionnaires about their eating habits, physical activity levels, sleep patterns, and other lifestyle factors. This information helps us understand the broader context of your health and how it might interact with the specific interventions being studied.
Physical symptom logs: Depending on the study, you might be asked to keep a diary or log of physical symptoms or changes you notice during the course of the study. This can provide valuable subjective data to complement the more objective measurements.
Mental health assessments: If a study investigates potential links between diet and mental health, participants may be asked to complete validated psychological questionnaires or assessments.
Remember, the exact tests you would undergo depend on the specific study in which you’re participating. Before each study, you will be fully informed about what tests are involved, what they entail, and why they’re important for the research. Your comfort and consent are paramount, and you will always have the option to opt out of any tests or the study as a whole.
