✦ High fat from commercial frying ✦ Very high sodium from added salt ✦ Minimal micronutrient content ✦ Large portions contribute significantly to daily calorie intake

Fine-cut chips from fast food outlets are thin, crisp fries cooked in commercial blended vegetable oils, typically at high temperatures. They are high in fat (often 10–15g/100g) and carbohydrate, and frequently very high in sodium from added salt. A large portion (~150g) can provide 450–550 kcal and 1.5–2g sodium. They offer minimal micronutrient value.

Preparation note

If eating fast food chips, opt for a small or medium portion and avoid adding extra salt. Sharing a portion or swapping for a side salad occasionally significantly reduces calorie and sodium intake.

How to read GI & GL

GI (Glycemic Index) rates how fast the carbohydrates in a food raise blood glucose compared to pure glucose (= 100). Low GI ≤ 55 means a slow, steady rise. But GI says nothing about how much carbohydrate you're actually eating.

GL (Glycemic Load) fixes that. It multiplies GI by the actual grams of carbohydrate per typical serving: GL = GI × carbs per serving ÷ 100. This makes it the more useful number for real-world blood sugar management.

Why they can disagree — a food with low GI can still carry a high GL if the serving is large and carb-dense. Conversely, watermelon has a high GI (72) but a low GL (4) because a normal portion contains very few carbs. Always read both together.

Low GL ≤ 10 Modest total glucose impact per serving.
Medium GL 11–19 Moderate impact — manageable for most.
High GL ≥ 20 Significant carb load per serving. Consider a smaller portion.

High GI food — causes a rapid rise in blood sugar. Best eaten in small portions combined with lower-GI foods, protein, or fat.

Glycemic Load (GL = GI × carbs ÷ 100) accounts for portion size. A moderate GL — portion size matters here.

* % Daily Value is the proportion of an adult EU Nutrient Reference Value (NRV) supplied by 100g of this food. NRVs are the labelling standard — the same basis as the “%RI” figures printed on food packaging — so these percentages are directly comparable with a shop label. They are a single adult figure and do not vary by age or sex, which is why they sometimes differ from UK dietary reference values: the NRV for vitamin C is 80mg where the UK RNI is 40mg. When Nutriofia assesses your own intake in the reports and trackers, it uses the age- and sex-specific UK values instead.

Fibre is shown without a percentage. Our fibre values use the UK Englyst NSP method, while the published 30g daily goal is an AOAC figure — the two are measured differently and a single percentage would mislead. How we source and normalise our data →
