Snacking in Ireland: What We're Actually Eating Between Meals
Safefood research shows that snacks now account for nearly a quarter of Irish adults' daily calorie intake. The question isn't whether to snack - it's what you're reaching for.
According to Safefood's National Adult Nutrition Survey, snacks and non-meal eating now contribute approximately 24% of total daily energy intake for Irish adults. That figure has grown consistently over the past two decades, tracking increases in irregular working hours, commuting time, and the availability of ultra-processed snack foods. The snacking habit itself isn't the problem - hunger between meals is a normal physiological signal. What's changed is what's typically available to reach for.
The Ultra-Processing Problem
NOVA classification groups foods by level of industrial processing. NOVA Group 4 - ultra-processed foods - includes most packaged snack products: crisps, confectionery, sweetened biscuits, flavoured cereal bars. A 2019 BMJ study of over 100,000 French adults found that every 10% increase in the share of ultra-processed food in the diet was associated with a 12% increase in all-cause mortality. Causal direction is debated, but the association is consistent across multiple large studies.
The relevance for snacking: most convenient, portable snack foods in Irish supermarkets fall into NOVA Group 4. This isn't a moral judgement about individual choices - it's a structural feature of what's been developed and marketed into snack occasions over the past 30 years.
What Actually Satisfies Hunger
The physiological purpose of snacking is to manage hunger between meals without disrupting the next meal. Protein and fibre are the two nutrients most effective at sustaining satiety - both slow digestion and blunt the blood sugar response that drives subsequent hunger. By these criteria, the most effective snack foods are broadly:
- Greek yogurt (plain, full-fat): 10g protein per 100g, low sugar, high satiety. A 150g portion is filling and costs under €0.50.
- Hard-boiled eggs: 6g protein per egg, portable, no packaging waste. Two eggs provide 12g protein at roughly €0.60.
- Hummus with raw vegetables: Protein and fibre from legumes, volume from vegetables. 200g hummus costs ~€1.50 and provides 4–5 snacking portions.
- Mixed nuts (unsalted): High calorie density means portions should be controlled (~30g), but they provide sustained energy without blood sugar spikes.
- Oatcakes with nut butter: Slower-digesting carbohydrates combined with fat and protein - a better option than rice cakes, which digest rapidly.
The "Health" Snack Marketing Problem
The snack food aisle has responded to consumer interest in healthier options with a proliferation of products carrying health-adjacent claims: "natural," "no artificial colours," "made with real fruit." As noted in our Tesco database analysis, many of these products underperform on nutrition relative to their positioning. Energy balls sweetened with dates, granola bars with 28g sugar per 100g, and "coconut water" drinks with added sugar all sit in this category.
The per 100g sugar column and the NOVA classification are more useful guides here than front-of-pack claims. Any product above 15g sugar per 100g and in NOVA Group 4 should probably be treated as a treat food rather than a regular snack, regardless of the packaging language.
