Ketone Ester and Salt (KEAS) in Older Adults

This study is looking at how a ketone supplement, called β-hydroxybutyrate (β-OHB), might help older adults counteract the effects of a high-salt diet. Many Americans eat too much salt, which can raise blood pressure and increase the risk of heart and kidney problems, especially in older adults. Researchers want to see if β-OHB can help manage blood pressure even when salt intake is high. You may be able to join if you are between 60 and 85 years old, have resting blood pressure no higher than 150/90, and are generally healthy without certain medical conditions like diabetes or heart disease. The study aims to enroll 35 participants and will measure changes in your resting blood pressure and how your blood pressure reacts to different situations.

Study design
This interventional study plans to enroll 35 participants. It will compare the effects of different dietary interventions on blood pressure.
What's involved
Participants will consume different dietary supplements (with or without salt and β-OHB) for ten days each, over a period of 3-4 months. Blood pressure will be measured on day 10 of each 10-day intervention.
Compensation
Not stated in the trial record.
Follow-up
Blood pressure measurements are completed on day 10 of each 10-day intervention over 3-4 months.

Eligibility criteria

Inclusion

Between the ages of 60-85
Resting blood pressure no higher than 150/90
BMI below 35 kg/m2 (or otherwise healthy)
Free of any metabolic disease (diabetes or renal), pulmonary disorders (COPD, severe asthma, or cystic fibrosis), cardiovascular disease (peripheral vascular, cardiac, or cerebrovascular)
Do not have any precluding medical conditions that prevent participants from exercising (i.e., cardiovascular issues, or muscle/joint issues including painful arthritis) or giving blood (e.g., blood thinners)

Exclusion

High blood pressure - greater than150/90 mmHg
Obesity (BMI \> 30 kg/m2)
History of metabolic disease (diabetes or renal disease), pulmonary disorders (e.g., COPD, severe asthma, \& cystic fibrosis), and cardiovascular disease (peripheral vascular, cardiac, or cerebrovascular).
Medical issues that prevent safe exercise (i.e., cardiovascular issues, or muscle/joint issues including painful arthritis)
Medical issues that prevent giving blood (e.g., blood thinners).
Current smoking, using smokeless tobacco, or vaping (within past 12 months)
Current pregnancy
  • Resting blood pressureThis measure is completed on day 10 of each 10-day intervention (low salt, high salt, high salt+ ketone) over 3-4 months and values will be compared across interventions.

    The investigators will measure systolic and diastolic pressure using a validated oscillometric device (Suntech CT40)

  • Blood pressure reactivity responsesThis measure is completed on day 10 of each 10-day intervention (low salt, high salt, high salt + ketone) over 3-4 months and values will be compared across interventions.

    The investigators will measure systolic and diastolic pressure using photoplethysmography at the finger and manually measure brachial pressures. Systolic and diastolic blood pressure will be assessed at rest and during submaximal cycling exercise. Blood pressure reactivity will be expressed as a change in pressure (mmHg) from baseline to a predetermined time during the stressor.
