What Happens to Your Metabolism
4. Blood Sugar May Stabilize
For people with type 2 diabetes or insulin resistance, cashews may offer real benefits.
The research: A study in people with type 2 diabetes found that those who got 10% of their calories from cashews for eight weeks had healthier insulin levels than those who didn’t . Other research has pointed to long-term regular nut consumption as helpful in preventing type 2 diabetes .

Replacing processed snacks with nuts reduces overall calorie intake
The research: A 2022 study found that people who ate a handful of nuts daily, including cashews, had a lower risk of cardiovascular disease . Swapping a high-carb snack for cashews appears to support weight management .
