Diet Ratings
Pistachios contain 5.7g net carbs per ounce, making them higher in carbs than most nuts. While technically keto-compatible in very small portions (0.3 oz), they're among the least ideal nut choices for strict ketosis.
Whole plant food with complete amino acids, antioxidants, and healthy fats. Minimally processed. Excellent nutritional density.
Pistachios are whole, unprocessed nuts available to Paleolithic humans. Rich in antioxidants and healthy fats. Universally accepted in paleo diets. No processing required.
Excellent Mediterranean nut with good monounsaturated fat profile, fiber, and polyphenols. Traditionally grown in Mediterranean regions. Strongly encouraged in moderation.
Tree nuts are plant seeds and excluded from carnivore diet. Plant-based protein and fat source.
Whole pistachios are compliant Whole30 foods. They are unprocessed nuts with no excluded ingredients, providing protein and healthy fats.
Pistachios are low-FODMAP only at very restricted portions (28 nuts or 28g per Monash), but contain higher fructans and GOS than other nuts. Larger servings exceed FODMAP thresholds. Strict portion control essential.
iMonash University limits pistachios to 28 nuts (28g) due to oligosaccharide content, while some practitioners recommend even smaller portions (15-20g) in strict elimination phase. Serving size is critical.
Excellent DASH nut with predominantly unsaturated fat. Good source of fiber, potassium, magnesium, and vitamin B6. Lower calorie density than most nuts. Supports cardiovascular health. Choose unsalted varieties.
Pistachios provide monounsaturated fat (7g per ounce) and decent protein (6g per ounce), but contain higher carbs (8g per ounce) than other nuts. Glycemic load is moderate. Usable in Zone but requires careful portioning.
Good source of polyphenols, particularly in red skin. Contains lutein and zeaxanthin with antioxidant properties. Favorable monounsaturated fat profile. Research supports anti-inflammatory and cardiovascular benefits. Lower in omega-6 than many nuts.
Pistachios offer good protein (6g per ounce) and excellent fiber (2.8g per ounce), with moderate fat (14g per ounce, mostly unsaturated). Better fat-to-protein ratio than most nuts. However, calorie-dense and portion control is difficult — easy to overconsume. Small handful works well; larger portions risk triggering GLP-1 side effects.
