About
What it is and where it shows up.
Roasted cashew is the heat-processed kernel of Anacardium occidentale, a tree nut native to tropical regions, widely consumed as a snack or food ingredient. Roasting enhances flavor, reduces moisture, and eliminates residual shell irritants (urushiol-related compounds), making the nut safe and palatable for consumption.
Safety summary
The regulatory and scientific consensus.
Roasted cashews are safe and nutritious for the general adult population, providing healthy monounsaturated fats, protein, magnesium, and zinc, with no established ADI as they are a whole food. The primary safety concern is tree nut allergy, which can cause severe reactions including anaphylaxis in sensitized individuals. Cashews are calorie-dense (~550–580 kcal/100 g) and should be consumed in moderation by those managing weight or cardiometabolic conditions.
Regulatory landscape
What food-safety regulators have decided.
| Jurisdiction | Status | Note |
|---|---|---|
| FSANZ (Food Standards Australia New Zealand) (Australia) | Approved | Cashews are permitted as a whole food under FSANZ Food Standards Code. Tree nuts, including cashews, are declared mandatory allergens under Standard 1.2.3 of the Australia New Zealand Food Standards Code, requiring allergen labelling on all packaged foods.source |
| EFSA (European Food Safety Authority) (European Union) | Approved | Cashews are freely permitted as a whole food in the EU. Under Regulation (EU) No 1169/2011 on food information to consumers, tree nuts including cashews (Anacardium occidentale) are listed in Annex II as a major allergen requiring mandatory labelling declaration in all prepacked and non-prepacked foods.source |
| FSSAI (Food Safety and Standards Authority of India) (India) | Approved | Cashew nuts (raw and roasted) are regulated under the Food Safety and Standards (Food Products Standards and Food Additives) Regulations, 2011. India is one of the world's largest producers and exporters of cashews; FSSAI sets quality and hygiene standards for nut processing, packaging, and labelling including allergen declarations under FSS (Labelling and Display) Regulations, 2020.source |
| FDA (Food and Drug Administration) (United States) | Approved | Cashews are recognized as a whole food (not a food additive); tree nuts including cashews are listed as one of the nine major food allergens under the Food Allergen Labeling and Consumer Protection Act (FALCPA) and its 2023 amendment (FASTER Act), requiring mandatory allergen declaration on labels. FDA also recognizes that consuming 1.5 oz per day of most nuts, including cashews, as part of a diet low in saturated fat and cholesterol, may reduce the risk of heart disease (qualified health claim per 21 CFR 101.14). |
Who should approach with care
Whose guidance would steer them away.
Nut Allergy — Cashew is one of the most potent tree nut allergens and can trigger severe IgE-mediated reactions including anaphylaxis; it is a mandatory-declaration allergen under FDA (FALCPA/FASTER Act), EU Regulation 1169/2011, FSSAI, and FSANZ standards.
Infants — Whole cashews pose a choking hazard for infants and young children under 4 years; introduction of tree nuts should follow pediatric allergy guidance, particularly for children with eczema or other food allergies who are at elevated risk of developing nut sensitization.
Kidney Disease — Cashews are high in potassium (~660 mg/100 g) and phosphorus (~593 mg/100 g), which patients with chronic kidney disease (CKD) on potassium/phosphorus restriction must limit per renal dietitian guidance.
Gout — Cashews contain moderate purines; while not as high-risk as organ meats, frequent high-quantity consumption may contribute to elevated uric acid levels in gout-prone individuals and should be moderated.
Ibs — Cashews are high in FODMAPs (fructans/GOS) and may trigger bloating, gas, or diarrhea in IBS patients, particularly those following a low-FODMAP diet under NICE/Monash University guidance.
