Diet Ratings
Feta is a full-fat cheese with negligible net carbs (less than 1g per ounce) and high fat content. Ideal for keto macros and adds flavor to meals.
Feta is a dairy cheese traditionally made from sheep or goat milk. Contains casein and whey, making it non-vegan.
Dairy product excluded from paleo diet. Cheese is processed milk and not available to Paleolithic humans.
Staple Mediterranean cheese, particularly in Greek and Eastern Mediterranean cuisines. Lower fat than many cheeses, rich in flavor allowing smaller portions, and traditionally paired with vegetables and olive oil.
Full-fat cheese from animal milk, traditionally made with minimal additives, high in fat and protein. Widely accepted in carnivore diet.
Dairy is explicitly excluded from Whole30. All cheese varieties, including feta, are non-compliant regardless of processing method.
Feta is a fermented cheese with very low lactose content. Monash University confirms feta as low-FODMAP at standard serving sizes (30g).
Very high sodium (1116mg per 100g) due to brining process. High saturated fat (21g per 100g). Single serving exceeds 10% of daily sodium allowance on standard DASH.
Similar to brie—high in saturated fat and sodium. Provides protein but fat composition is not Zone-optimal. Small portions can work within a balanced meal.
Traditional Mediterranean cheese with some anti-inflammatory merit due to cultural context in Mediterranean diet. Moderate saturated fat and contains beneficial compounds, but still calorie and fat-dense. Portion control essential.
iDr. Weil's pyramid includes feta as acceptable in Mediterranean context; however, mainstream anti-inflammatory guidance emphasizes limiting full-fat dairy due to saturated fat content.
Feta is calorie-dense and high in saturated fat (7g per ounce), which triggers GLP-1 side effects. While it provides protein and calcium, the fat-to-protein ratio is unfavorable for GLP-1 patients. Small amounts as a flavor accent are acceptable; larger portions should be avoided.
