Meta-analyses of Soy Protein and Its Food Sources for Cholesterol Reduction
Canada1 participantsStarted 2021-05-01
Plain-language summary
Although soy protein has approved health claims in Canada and the US, and is recognized by major cardiovascular clinical practice guidelines for the reduction of cholesterol and risk of coronary heart disease (CHD), these claims are based almost exclusively on evidence from foods containing isolated soy protein (ISP). The role of other non-ISP food sources of soy protein (e.g Tofu, tempeh, edamame) in these effects is unclear. The role of food form and matrix (e.g soy beverage versus meat analogue) on the effects of ISP is also unclear. As national dietary guidelines and clinical practice guidelines for nutrition therapy shift from a focus on single nutrients to a focus on foods and dietary patterns, it is important to understand whether non-ISP food sources of soy protein and ISP food sources with different food matrices produce the same reductions in LDL-cholesterol and CHD risk. To strengthen the evidence-base for health claims and guidelines development, the investigators will conduct a systematic review and meta-analysis of randomized controlled trials of the effect of ISP and non-ISP food sources of soy protein on stablished lipid targets in individuals with and without dyslipidemia.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
