How do you choose a good snack?

A good snack carries three qualities at once: it is small, it is defined and it carries you to the next meal. The aim of a snack is not to end hunger but to make the gap manageable — when this distinction is not made, the snack quietly turns into a fourth meal.

Below we look at when a snack is needed, which criteria the choice is made with, how the portion is defined and why eating from the package creates a problem.

Is a snack always needed

A snack is not a rule but the answer to long gaps. If your meals stand close together, adding an item in between is usually unnecessary; when the gap is short, anything added is simply written into the day's total.

If the gap is getting long the situation changes. For someone who has an early breakfast and a late lunch, a small meal placed in between clearly slows the pace at the lunch table.

This is why the first question should not be "what should I eat" but "am I really hungry". If the answer is not clear, drinking a glass of water and waiting a few minutes is a harmless way of telling the two apart.

The three criteria of the choice

The first criterion is how filling it is: an item carrying protein or fiber carries you longer than another item of the same size. Yogurt, fruit and nuts are the most easily reached members of this group.

The second criterion is being defined. A portion with a clear limit, such as a bowl, a handful or one piece, is easier to manage than an open package. An item with no clear limit does not end even when the hunger does.

The third criterion is being at hand. The best snack is the one within your reach at that moment; an option that is planned but not in the house is no option at all in practice.

How the portion is defined

For nuts the measure is set: a handful of almonds is defined as 24-26 pieces, that is 30 grams. This measure looks small, but considering the density of nuts it is an adequate portion.

For fruit the measure is built over pieces; one standard portion of banana is given as 100 grams. Counting by pieces is practical, but it shifts when the size of the fruit changes.

We covered the concrete breakdowns, with their portions, in how many calories in a handful of almonds.

Why eating from the package is a problem

With a snack eaten straight from the package, the amount is invisible. How much has gone is only understood when the package feels lighter, and by that point the decision has already been made.

Setting the amount out onto a plate or into a small bowl beforehand largely closes this problem. When the amount put in front of you is finished, the snack finishes too; carrying on takes a separate move.

Small packages do the same job, but their unit cost is high. Dividing a large package into small containers at home is both cheap and gives the same result.

When it is eaten

The hour of a snack works best when it falls in the middle of two main meals. A snack eaten very close to a main meal reduces the appetite for that meal and upsets the pattern.

The evening hours are a separate heading; there, snacking most often comes not from hunger but from tiredness and habit.

An active day shifts the hour too. A small meal taken before a long walk or exercise keeps the hunger that follows manageable.

At work and at school

Snacks eaten at a desk are usually consumed without being noticed. A package sitting in a drawer is opened not by hunger but by a hand reaching for it.

Reducing visibility affects this behavior directly. The same product is consumed far less when it stands in a closed container and out of sight.

Conversely, washed fruit or nuts divided into small containers being visible brings the item you prefer forward on its own.

Two common mistakes

The first is building the snack at the size of a main meal. This grows the day's total instead of managing the gap, and upsets the next meal as well.

The second is banning snacks completely. If the gap really is long, skipping the snack is one of the most common reasons the evening table grows.

What to keep at home

The choice is made according to what is in the house at that moment. This is why the real decision is made at the store shelf; a product that does not come into the house is not eaten in the evening either.

Yogurt, fruit, nuts and a whole grain product make up an adequate basket in most homes. All four keep well and need no preparation. When these four items are at hand, the snack decision is not made again from scratch each time.

In short: ask about the gap, choose a filling and defined item, eat from a bowl rather than the package, and make the choice at the store. You can find the whole picture in the snacks and sweet cravings guide and the individual records on the food library page.
