Effects of Dried Whole Fruits on Metabolism in Diabetes
Researchers are investigating if dried Saskatoon berries could be a safer way to help people with prediabetes or newly diagnosed type 2 diabetes. They believe these berries might help control blood sugar, improve gut health, and reduce other health risks. The study will compare eating dried Saskatoon berries to eating dried apple slices over 12 weeks. Scientists want to see if the berries can help with conditions like insulin resistance, a problem where the body doesn't use insulin properly. The goal is to find natural food options that support better health for people with diabetes, potentially offering a way to manage the condition with fewer side effects than some medicines.
At a glance
What is this study about?
Many people around the world are developing diabetes, especially type 2 diabetes, which makes up most cases. Type 2 diabetes means your body isn't using insulin properly, often due to being overweight, and this can lead to serious health problems like heart attacks, strokes, and kidney issues if not managed well. While there are medicines to help, they can sometimes have side effects. This is why scientists are looking into natural foods that might help manage diabetes more safely.
Saskatoon berries are a popular fruit in parts of Canada and the US. Earlier studies in laboratories and with healthy people have shown promising results, suggesting these berries might help lower blood sugar, reduce 'bad' cholesterol, and improve gut health. Now, researchers want to see if these benefits apply to people who are diagnosed with prediabetes or who have recently been diagnosed with type 2 diabetes. They want to understand how eating these berries might affect blood sugar levels, how the body uses insulin, and the types of good bacteria in the gut.
This study aims to compare the effects of eating a specific amount of dried Saskatoon berries each day versus eating dried apple slices. By doing this comparison, they hope to get a clear picture of whether Saskatoon berries could be a helpful addition to managing prediabetes and type 2 diabetes, potentially offering a natural way to improve health.

- Goal is to see if berries can help with blood sugar and gut health.
- Participation involves eating dried fruit daily for 12 weeks.
- Designed for adults aged 18-74 not currently on diabetes medication.
- Potential to find natural ways to support diabetes management.
Who may be eligible?
To join this study, you need to be an adult between 18 and 74 years old. You should have prediabetes or newly diagnosed type 2 diabetes. It's important that you have not started any regular treatment for your diabetes, such as medications for blood sugar, cholesterol, or high blood pressure, within the last month. You also can't have taken antibiotics recently.
There are some health conditions that would prevent you from taking part, such as if you've recently had a heart attack or stroke, or if you have serious kidney or liver disease, or certain cancers. This study is not for those who are pregnant, breastfeeding, or have allergies to fruits.
Ultimately, the research team will decide if you're a good fit after reviewing your health information and if you agree to take part by signing a consent form.
Could this study suit you?
Answer these quick questions to see if you may be eligible. This is a guide only — the research team makes the final call.
- Are you between 18 and 74 years old?
- Do you have prediabetes or newly diagnosed type 2 diabetes?
- Have you *not* taken diabetes, cholesterol, or blood pressure medicines in the last month?
- Have you *not* taken antibiotics in the last month?
- Are you *not* pregnant or breastfeeding?
- Are you *not* allergic to fruits?
What does participation involve?
If you decide to join this study, you'll be one of over 90 participants. You'll be randomly placed into one of two groups: one group will eat dried Saskatoon berries, and the other will eat dried apple slices. You won't know which fruit you're getting, as the packages will be labelled only with a special ID to keep things fair.
You'll need to eat 40 grams of your assigned dried fruit every day for 12 weeks. During this time, you'll have a few scheduled visits to the clinic. At your first visit, you'll go through screening and fill out questionnaires about your diet and daily activities. Your height, weight, and blood pressure will also be measured. More details about follow-up visits and what will happen during them will be provided.

Will I know if I'm eating Saskatoon berries or apples?
No, you won't know which fruit you're getting during the study. This helps ensure fair results.
How long does the study last?
You will eat the dried fruit for 12 weeks, and there will be a few clinic visits during that time.
Will this study replace my current diabetes treatment?
No, this study is for people who are not currently on medication for their diabetes. It's not a replacement for medical advice or treatment.
