Nutrition Facts
Per 100g

Diet Ratings

Keto1/10AVOID

Corn syrup is a refined sweetener composed of glucose and maltose with approximately 15-16g net carbs per tablespoon. Completely incompatible with ketogenic diet. Rapid glucose absorption disrupts ketosis immediately.

Vegan6/10CAUTION

Corn syrup is plant-derived with no animal products, making it technically vegan. However, it is highly processed and refined, with minimal nutritional value. Most vegans prefer whole-food sweeteners.

Paleo1/10AVOID

Corn syrup is a highly processed sweetener derived from corn (a grain excluded by paleo diet). It is created through industrial enzymatic processing and represents processed food technology. Paleo diet excludes both grains and refined sugars.

Mediterranean2/10AVOID

Corn syrup is a highly processed sweetener derived from corn starch. It is not a traditional Mediterranean ingredient and contradicts core diet principles. It offers no nutritional value beyond calories and is associated with metabolic dysfunction. The Mediterranean diet explicitly rejects such refined sweeteners.

Carnivore1/10AVOID

Corn syrup is derived from corn starch through enzymatic hydrolysis. It is plant-derived and represents concentrated carbohydrates, fundamentally incompatible with carnivore principles.

Whole301/10AVOID

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

Low-FODMAP8/10APPROVED

Corn syrup (standard, not high-fructose) is primarily glucose and is low-FODMAP. Monash University confirms it is acceptable at typical sweetening doses. Does not contain significant fructose or polyols.

DASH1/10AVOID

Corn syrup is pure glucose polymer with no nutritional value. Highly processed, rapidly absorbed, and contributes to blood sugar spikes. DASH explicitly avoids added sugars and refined carbohydrates; corn syrup is a primary target for elimination.

Zone2/10AVOID

Corn syrup is a high-glycemic refined carbohydrate with a GI of ~100. It causes rapid insulin spikes, directly violating Zone's low-glycemic carbohydrate requirement. It is nutritionally empty and pro-inflammatory. Dr. Sears explicitly recommends avoiding refined sugars.

Corn syrup is a refined carbohydrate with high glycemic index and pro-inflammatory effects. Promotes insulin spikes, weight gain, and metabolic dysfunction. Strongly discouraged in anti-inflammatory diets. Associated with processed foods and HFCS concerns.

Pure sugar with zero nutritional value, zero protein, zero fiber. Causes rapid blood sugar spikes and crashes, directly counteracts GLP-1 mechanism. Extremely calorie-dense with no satiety benefit.

Controversy Index

Score range: 18/10. Higher controversy = more disagreement between diets.
