Cashew flour
Finely milled cashew kernels; naturally gluten-free, mildly sweet, and rich in healthy fats and minerals.
Should I eat Cashew flour?
Cashew flour is a minimally processed, nutrient‑dense nut flour with a low glycemic impact. For most people it can be a smart swap for part of refined flour, but watch portions and avoid solvent‑defatted versions if you prefer a simpler process.
Summary
Cashew flour is made by milling cashew kernels and sometimes defatting them; full‑fat versions resemble the whole nut’s nutrition, while defatted versions are lower in oil and higher in protein by percentage. It provides minerals like magnesium and copper and, unlike refined flours, has a low glycemic index, so it generally raises blood sugar more slowly. The biggest drawbacks are its calorie density and the fact that cashew is a major allergen that can trigger severe reactions in sensitive people. A subset of products are solvent‑defatted; choosing full‑fat or cold‑pressed/mechanically defatted flour avoids that processing step. Overall, it’s a health‑forward ingredient for many shoppers, with the caveats of allergy and portion control.

Why is it used?
Origin
Cashews are native to northeastern Brazil but were spread globally by Portuguese traders in the 16th century to India and East Africa. Today, kernels are widely processed in India, Vietnam, and West Africa. Milling kernels into flour is a straightforward extension of roasting/peeling lines used for snack nuts; some producers cold-press or solvent-defat kernels first to reduce oil for better baking performance.
Process: Roast, peel, optionally defat, then mill and sieve

Research Summary
Digestive Effects
Because it is rich in fat, large amounts of cashew flour may cause fullness, nausea, or loose stools in some people, especially if they are not used to high‑fat foods. Individuals with fat‑malabsorption (for example, after gallbladder removal or with pancreatic issues) may be more sensitive and could tolerate smaller portions better. The low glycemic index of cashews means cashew flour is less likely to cause rapid spikes and crashes in blood sugar than refined flours, but overall meal composition still matters. Defatted cashew flour lowers the fat load and may be better tolerated for those sensitive to dietary fat.
Limit Consumption
People with known tree‑nut allergy must strictly avoid cashew flour; cashew allergens are potent and labeling is mandatory in the US and EU. For infants and young children, introduction of nut allergens should follow pediatric guidance; avoid if an allergy is diagnosed. Individuals with fat‑malabsorption or certain GI conditions may feel better with modest amounts or defatted versions. While not a consumer exposure, workers who process cashew shells can suffer burns from cashew shell oil, highlighting the value of choosing suppliers with documented safety practices.
