How the diets react
Diet Ratings
Medium net carbs (~3-4g per medium tomato). Small portions fit keto, but cumulative intake requires tracking. Raw tomatoes are better than cooked/concentrated forms.
Strict keto practitioners avoid tomatoes entirely due to sugar content and potential insulin response, while mainstream keto allows small portions as part of salads or sauces.
Whole plant food with no animal products or derivatives. Nutrient-dense and widely consumed in vegan diets.
Tomatoes are nightshade vegetables available to Paleolithic humans. They are unprocessed, nutrient-dense, and contain no grains, legumes, or dairy. Widely accepted across all paleo authorities.
Tomatoes are a cornerstone of Mediterranean cuisine, rich in lycopene, vitamin C, and potassium. Used extensively in traditional dishes across Mediterranean regions. Low calorie, nutrient-dense, and minimal processing when fresh.
Tomato is a plant-derived fruit containing carbohydrates, fiber, and plant compounds. Carnivore diet excludes all plant foods without exception.
Whole vegetables are explicitly allowed. Tomatoes are unprocessed, nutrient-dense vegetables with no excluded ingredients.
Monash University has tested tomato and confirmed low-FODMAP status at standard serving sizes (1 medium tomato or 150g). Contains minimal fructans and polyols.
Excellent DASH food. Low sodium, rich in potassium, lycopene, and vitamin C. Supports cardiovascular health. Fresh tomatoes are preferred over canned (which may contain added sodium).
Low-glycemic vegetable with good micronutrients and lycopene (anti-inflammatory). However, moderate carb density (~5g net carbs per medium tomato) requires portion awareness. Best used as part of mixed vegetable dishes rather than sole carb source.
Rich in lycopene, a powerful antioxidant with documented anti-inflammatory properties. Contains vitamin C, potassium, and polyphenols. Cooked tomatoes have enhanced bioavailability of lycopene.
Low calorie, high water content, good fiber (especially with skin), nutrient-dense (lycopene, vitamin C), easy to digest, supports hydration. Minimal fat. Works well in small portions.
