How the diets react
Diet Ratings
One medium guava contains approximately 5g net carbs with minimal fat. While technically within carb limits for small portions, the fruit classification and sugar content make it a lower-priority choice for most keto practitioners.
Strict keto protocols avoid all fruits categorically; some practitioners argue guava's natural sugars can trigger cravings despite low net carb count.
Whole plant fruit with no animal products or derivatives. Excellent source of vitamin C and fiber.
Whole tropical fruit available to Paleolithic humans. Exceptionally high in vitamin C and fiber, low glycemic impact. Unprocessed natural food with excellent nutrient density.
Exceptional vitamin C content, high fiber, and antioxidants. Whole fruit with minimal processing. Aligns with Mediterranean principles of nutrient-dense plant foods despite tropical origin.
Guava is a tropical fruit with plant-based carbohydrates and sugars. Excluded from carnivore diet.
Whole fruit with no added ingredients. Naturally compliant as a fruit.
Monash University data indicates guava is low-FODMAP at restricted portions (approximately 150g). Larger servings may exceed fructose thresholds.
Clinical FODMAP practitioners may recommend caution due to variable fructose content depending on ripeness and variety.
Excellent DASH fruit. Very low sodium, high potassium, exceptional fiber content, very high in vitamin C. One of the most nutrient-dense fruits for DASH.
Low glycemic index, exceptional fiber content (3g per fruit), high in vitamin C and polyphenols. One guava (~12g carbs, 3g fiber = 9g net carbs) is perfect Zone carb block. Sears specifically recommends high-fiber, low-glycemic fruits.
Exceptional vitamin C content (higher than citrus), polyphenols, and fiber. Low glycemic index. Excellent antioxidant and anti-inflammatory profile. One of the most nutrient-dense fruits for anti-inflammatory purposes.
Excellent fiber (5.4g per 100g) and moderate protein (2.6g per 100g) for a fruit. High vitamin C and water content (81%). Low calorie density (68 cal per 100g). Natural sugars (9g per 100g) are moderate and balanced by fiber. Easy to digest, nutrient-dense, and portion-friendly. One of the best fruit choices for GLP-1 patients.
