Glucose impact

Low

Glucose risk

Eggs contain less than 0.1g of carbohydrate per 100g, which is nutritionally negligible. They have virtually no effect on blood glucose levels. The combination of protein and fat in eggs actually helps slow the absorption of carbohydrates from other foods eaten at the same meal, making eggs a useful addition to any blood-sugar-conscious diet.

Processing level

NOVA 1 (unprocessed)

Whole eggs in their shell are a single-ingredient, unprocessed food. Whether free range, organic, barn, or conventional — the nutritional profile and NOVA classification are identical. Every egg product we checked at Tesco contains exactly one ingredient: egg.

What to watch for when shopping

Whole eggs are always NOVA 1 regardless of brand, size, or farming method. The only egg products that score higher are liquid egg whites with preservatives, pre-made omelettes, or egg-based ready meals. If you are buying eggs in their shell, every option at Tesco is nutritionally equivalent. Budget tip: Tesco Medium Free Range Eggs 12 Pack at £2.80 (23p per egg) offers the best value for free range.
