How the diets react
Diet Ratings
Pecans are excellent for keto: ~1.7g net carbs per ounce, 20g fat, 2.6g protein per ounce. Very low carb, high fat, rich in antioxidants. One of the best nut choices.
Whole plant food, rich in antioxidants, healthy fats, and minerals. Minimally processed. Excellent nutritional profile and fully plant-based.
Pecans are whole nuts with a favorable omega-3 to omega-6 ratio and high monounsaturated fat content. They are unprocessed, ancestral, and universally approved by paleo authorities. No significant controversy exists.
Nutritious nut with healthy fats and antioxidants, but not native to Mediterranean region. Higher in calories and fat. Acceptable in moderation but not a traditional Mediterranean staple.
Tree nut and plant seed. Plant-derived and explicitly excluded from carnivore diet along with all nuts and seeds.
Pecans are whole, unprocessed tree nuts explicitly allowed on Whole30. They are a compliant source of healthy fats and antioxidants. No excluded ingredients.
Pecans are low in FODMAPs at standard serving sizes. Monash supports 15 pecan halves (14g) as low-FODMAP.
Good source of monounsaturated fats, fiber, and magnesium. Lower in saturated fat than cashews. Supports DASH principles. Acceptable in moderation. Choose unsalted varieties.
Pecans are primarily monounsaturated fat with low carbs (~4g per ounce), making them Zone-compatible. However, they contain slightly higher omega-6 than almonds or macadamia nuts. Approximately 0.75 ounce (15-17 halves) = 1 fat block. Acceptable but not optimal compared to almonds.
Good source of polyphenols and antioxidants, particularly ellagic acid. Reasonable omega-6 to omega-3 ratio. Anti-inflammatory compounds support cardiovascular health. Solid choice though slightly less omega-3 than walnuts.
Pecans provide 2.6g protein and 2.7g fiber per ounce but are calorie-dense (196 cal/oz) with 20g fat per ounce. While mostly unsaturated, the high fat concentration may worsen GLP-1 side effects in sensitive patients. Better as an occasional garnish than a staple snack.
Controversy Index
Score range: 1–9/10. Higher controversy = more disagreement between diets.
