This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.

What is this trial?

This study is testing whether a set of special low-protein foods called FLAVIS® makes it easier for people with chronic kidney disease to stick to a low-protein diet. Doctors recommend that people with kidney disease eat less protein to help prevent their kidneys from getting worse and to improve their quality of life. The study will compare two groups: one that follows a low-protein diet alone, and another that follows the same diet but also gets access to the special FLAVIS® foods.

Many people with kidney disease struggle to follow a low-protein diet because regular food options don't help them hit their protein targets. Researchers want to see if having easy-to-use, specially designed low-protein foods makes the diet easier to stick with and leads to better health outcomes.

Do you qualify?

You likely qualify if…

you have been diagnosed with chronic kidney disease at stage 3A, 3B, 4, or 5 and are not yet on dialysis
you are motivated and willing to change your diet with professional guidance and support
you currently eat more than 1 gram of protein per kilogram of your body weight each day
you have never tried a low-protein diet before
you are in generally good nutritional health with no signs of malnutrition
you are able to attend study visits and complete food records and questionnaires

You likely don't qualify if…

you have dialysis or a kidney transplant planned within the next 12 months
you have diabetes that is not well controlled
you have active cancer or a history of cancer within the last 5 years
you are allergic to milk, eggs, soy, or nuts
you are currently taking part in another clinical trial

What participation looks like

If you join this study, you will be randomly assigned to either follow a standard low-protein diet or to follow the same diet while also using the FLAVIS® special low-protein foods. You'll attend regular follow-up visits where researchers will check your kidney function through blood and urine tests, and you'll keep food records and answer questionnaires about your diet and quality of life. The study lasts about one year, and you'll receive counseling and support to help you stick with your new eating plan.
