Nutrition Facts
Per 100g

Diet Ratings

Keto1/10AVOID

High fructose corn syrup (HFCS) contains 42-55% fructose and is approximately 15-16g net carbs per tablespoon. Fructose is particularly problematic for ketosis and metabolic health. Completely incompatible with ketogenic diet.

Vegan5/10CAUTION

HFCS is plant-derived but heavily processed and refined. While technically vegan, it has significant health concerns and is environmentally problematic. Most vegans actively avoid it.

Paleo1/10AVOID

HFCS is a highly processed sweetener derived from corn (a grain) through industrial enzymatic conversion. It represents the antithesis of paleo principles: grain-derived, heavily processed, and refined. Paleo diet strictly excludes this product.

Mediterranean1/10AVOID

High fructose corn syrup (HFCS) is a highly processed sweetener with a high fructose concentration. It is strongly associated with metabolic dysfunction, fatty liver disease, and inflammation. It directly contradicts Mediterranean diet principles and is explicitly avoided in evidence-based Mediterranean nutrition guidance.

Carnivore1/10AVOID

HFCS is corn syrup enzymatically converted to increase fructose content. It is plant-derived, highly processed, and represents concentrated simple sugars—completely incompatible with carnivore diet.

Whole301/10AVOID

High fructose corn syrup is a processed sweetener and added sugar. Whole30 explicitly prohibits all added sugars including HFCS.

Low-FODMAP2/10AVOID

High fructose corn syrup (HFCS) contains 42-55% fructose, exceeding glucose content. This creates excess fructose, a key FODMAP. Monash University rates it as high-FODMAP. Avoid entirely.

DASH1/10AVOID

HFCS is 55% fructose, 42% glucose. Fructose is preferentially metabolized to fat in the liver, promoting visceral adiposity and dyslipidemia. DASH explicitly avoids HFCS due to metabolic harm and contribution to hypertension-related obesity.

Zone1/10AVOID

HFCS is a processed sweetener with high glycemic impact and metabolic dysfunction risk. Dr. Sears explicitly identifies refined sugars and syrups as Zone-incompatible. Causes rapid insulin spike and inflammatory response.

HFCS is a primary inflammatory culprit. High fructose content promotes hepatic lipogenesis, visceral fat accumulation, and systemic inflammation. Extensively documented in anti-inflammatory literature as a food to eliminate. No nutritional value.

High fructose corn syrup is a concentrated sweetener (55 calories, 15g carbs per tablespoon) with no nutritional value. Metabolized differently than glucose, with potential for increased liver fat deposition—particularly problematic in weight loss patients. Triggers rapid blood sugar and insulin spikes. Empty calories that directly displace protein and fiber. No place in GLP-1 diet.
