Diet Ratings

KetoApproved

Hazelnuts contain ~2g net carbs per oz with 91% fat content. Excellent keto nut choice with good micronutrient profile.

VeganApproved

Whole plant-based tree nuts. No animal products or derivatives.

PaleoApproved

Hazelnuts are whole, unprocessed nuts with a long history of human consumption. Good source of healthy fats, minerals, and antioxidants. No processing or anti-nutrient concerns. Universally approved in paleo.

MediterraneanApproved

Hazelnuts are grown throughout Mediterranean regions and provide healthy monounsaturated fats, vitamin E, and antioxidants. Integral to Mediterranean nut consumption patterns.

CarnivoreAvoid

Hazelnuts are tree nuts and plant-derived. Carnivore diet excludes all nuts and plant foods. No animal products.

Whole30Approved

Hazelnuts are whole tree nuts with no excluded ingredients. They are explicitly allowed on Whole30 as a natural fat and protein source.

Low-FODMAPCaution

Hazelnuts contain moderate fructans. Monash University data suggests small portions (approximately 10 nuts or 1 ounce) are low-FODMAP, but larger servings exceed FODMAP thresholds.

Debated

Monash University specifies portion-dependent status; some practitioners recommend avoiding entirely during strict elimination phase due to cumulative fructan load.

DASHApproved

Tree nuts are core DASH foods. Hazelnuts provide magnesium, potassium, fiber, and monounsaturated fats. Low sodium naturally. Excellent cardiovascular nutrient profile.

ZoneApproved

Hazelnuts are ~80% monounsaturated fat, making them one of the best nut choices for Zone. Low-glycemic, rich in polyphenols and vitamin E, and support anti-inflammatory goals. Hazelnut butter or whole nuts work well as Zone fat blocks. Requires portioning but aligns perfectly with Zone principles.

Hazelnuts are excellent sources of polyphenols, vitamin E, and monounsaturated fats. Research supports anti-inflammatory benefits. Whole food form with minimal processing ideal for anti-inflammatory diet.

Hazelnuts contain 17g fat and only 4g protein per ounce (176 calories). High fat content relative to protein makes them likely to trigger nausea or bloating. Calorie-dense with poor protein density for GLP-1 patients needing 100-120g daily protein.

Score range: 19/10. Higher controversy = more disagreement between diets.
