Quick answer: the healthiest snacks are whole foods with protein, fibre or whole grains. Think fruit, vegetables, nuts, yoghurt, eggs, hummus and plain popcorn. Evidence on whether snacking helps or harms weight is mixed, so the best snack is one that fits your hunger, your meals and your health needs. Watch portions, since a handful of nuts packs far more energy than a handful of grapes.
Healthy snacks can help you bridge long gaps between meals. They can also add extra energy without making you feel any fuller. This guide lists real snacks with energy per portion, explains what the research says, and flags a few safety points.
Healthy Snacks Compared by Portion
| Snack | Portion | Energy (kcal) |
|---|---|---|
| Plain rice cake | 1 | 30 |
| Low-fat cottage cheese | 60 g | 43 |
| Dried apricots | 3 (30 g) | 56 |
| Hard-boiled egg | 1 medium | 66 |
| Small olives | 20 | 75 |
| Almonds | 12 | 80 |
| Low-fat Greek yoghurt | 125 g | 80 |
| Breadstick with low-fat hummus | 1 plus 1 tbsp | 90 |
| Pistachios | 24 (15 g) | 90 |
| Walnuts | 7 halves | 92 |
| Plain popcorn | 20 g | 94 |
| Fruit | 1 average portion | 40 to 100 |
Notice the spread. A rice cake and 24 pistachios are both “healthy,” yet the pistachios carry about three times the energy. Nuts are nutritious, but the NHS says they are high in energy, so portion size matters.
What the Evidence Says About Snacking
Harvard’s Nutrition Source says snacking has been linked to both weight gain and weight maintenance. It has also been linked to both better and worse diet quality. Part of the confusion is that “snack” has no common definition.
Some studies found that snacking when you are not hungry was linked to higher total intake. People who eat when stressed also tend to pick sweeter, fattier snacks. Therefore, the useful question is not “should I snack?” but “am I actually hungry?” Harvard suggests snacking when several hours have passed since a meal, and checking first whether boredom or stress is driving the urge.
How to Pick Healthy Snacks That Satisfy
Harvard suggests whole foods with protein, fibre or whole grains, since they may be more satisfying. It groups ideas by what you crave:
- Crunchy: raw vegetable sticks or whole-grain crackers
- Creamy: yoghurt or hummus
- Sweet: fresh fruit or dark chocolate
- Savoury: cheese, roasted chickpeas or nut butter
The NHS calls fruit and vegetables “always the best choice” and notes they count toward 5 A Day. It also suggests limiting packaged snacks to two a day at most. For fruit ideas, see our guide to the best fruits for weight loss.
Eating habits matter too. Harvard notes that eating in front of a screen distracts you from how much you eat. Large packs can hold two or three servings, and a wide variety of snacks can raise intake. Pre-portion snacks into a bowl instead of eating from the bag. A boiled egg also works well, as our guide on calories in boiled eggs shows.

Safety Notes on Healthy Snacks
- Nut allergy: check labels, since peanuts and tree nuts can cause serious reactions.
- Young children: the NHS says not to give whole nuts to children under 5 because of choking.
- Dried fruit: the NHS says to eat it at mealtimes only, to lower the risk of tooth decay.
- Diabetes: if you take insulin or similar medicines, ask your care team how snacks fit your plan.
- Disordered eating: if snacking feels out of control, or you restrict afterwards, speak to a doctor or therapist.
