Brief Summary

This study aims to demonstrate the effect of visualizing the effect of consuming a functional milk on postprandial glucose response on perceived benefits compared to absence of visualization.

Detailed Description

This is a multi-centric double-blind, randomized, 2-arm parallel group clinical study to investigate the effect of of consuming a functional milk on postprandial glucose response on perceived benefits compared to absence of visualization.

The study is divided in 3 periods: 1) reference period in which both groups will have a blinded Continuous Glucose Monitoring (CGM) sensor; 2) intervention period where participants will have either CGM feedback visualization or blinded CGM feedback visualization, while both arms consume a functional milk powder; 3) follow-up in free-living conditions.

Outcomes of this study will include plasma HbA1c, glucose, insulin and lipids levels, perceived benefits and adherence questionnaire, dietary intake and physical activity and real usage.

This will be conducted in a total of 170 healthy adults of Chinese ethnicity aged 45-75 years

4. Age: 45-75y (inclusive 45 and 75)

5. Males and females

6. HbA1c ≤ 6.4 % and FPG ≤ 6.90 mmol/L (125 mg/dl) to exclude diabetic individuals based on the National Institute of Health and Care (NICE) criteria

7. Regularly consuming a carbohydrate containing breakfast (≥30g of total CHO) assessed by a food recall only at breakfast of the previous day to the screening visit

8. Having a sedentary lifestyle meaning do not usually conduct vigorous*-intense physical activity and are willing to abstain from it during reference and intervention period

9. If on chronic medication such as lipid-lowering, thyroid medication, etc., the dosage must be constant for at least 3 months prior to screening.

• Activities such as jogging, running, carrying heavy objects or other loads upstairs, shoveling snow, participating in a fitness class, and fast swimming, that will lead to hard and fast breathing.

Exclusion Criteria

1. Pre-existing chronic medical condition and/or history of significant medical condition (e.g. malignancy, significant organ dysfunction, autoimmune and/ or genetic disease, gastrointestinal disease, endocrine disease (e.g. diabetes mellitus, history of hypoglycemia, polycystic disease syndrome, Addison's disease, Cushing's syndrome, acromegaly), acute or chronic infectious condition (e.g. hepatitis B and C, HIV, tuberculosis), cardiovascular disease (heart failure, angina, myocardial infarction, stroke), renal disease (renal insufficiency), hepatic (liver cirrhosis, liver failure) or respiratory disease (COPD), hematological disorder (e.g. anemia), neurological and/or psychiatric conditions (e.g. depression, psychotic disorders, chronic insomnia eating disorder), as diagnosed by the treating physician, which in the opinion of the site physician/ investigator may risk participant wellbeing/ safety, impede participant compliance with study procedures or ability to complete the study and/ or could confound the primary objectives of the study.

2. Any acute illness or any recent medical/ surgical intervention within 3 months prior to enrolment potentially interfering with study procedures and assessments.

3. Known or suspected cow's milk protein allergy (CMPA), lactose and /or soy intolerance /hypersensitivity.

5. Current smoker (e.g., cigarette, tobacco, cannabis) who exceeds 5 cigarettes per week.

6. Patients with refractory hypertension, and patients with hypertension who are taking antihypertensive drugs (beta-blockers, thiazide diuretics) that may affect blood glucose metabolism.

7. Female participants currently on hormonal therapy including post-menopausal hormone Replacement Therapy (PRT) or have been on PRT treatment in the past two months before study participation.

8. Participants on systemic corticosteroids, glucocorticoids, or cyclosporine A.

9. Female participants who are pregnant or intending to become pregnant, lactating and or breastfeeding.

10. Participants who had a significant weight loss (≥5%) within the last 6 months or follow a weight loss programme.
