Cashews are more suited to a regular snack during your marathon training than as an obvious source of quick fuel just before an intense run. Hardlopen.nl points out that a meal high in fat, fibre and protein may feel heavier when eaten closer to a run. So consider when you eat them, their ingredients and how much your household gets through. A 500 g bag is a good choice if you use cashews regularly and can store them properly; if you eat them less often, a smaller pack is more practical.
If you want to fit cashews into your training week, treat a regular snack separately from food eaten just before an intense run. Hardlopen.nl explains that a meal high in fat, fibre and protein may feel heavier when eaten closer to a run.
If you buy nuts regularly, consider whether your household will actually get through a large bag. Product listings from Albert Heijn, Jumbo, PLUS and ALDI show a range of pack sizes.
If you only eat small amounts, like to alternate between different varieties or prefer to open less stock at a time, pack size and storage instructions matter. Voedingscentrum recommends storing nuts in a tightly sealed container in a cool, dry place.
First, distinguish between a regular snack and food eaten shortly before a run. Then check the label and choose a pack that suits how much you eat and how you can store it.
| What to consider | What to check | Who might find this important? |
|---|---|---|
| When you eat them | Consider whether you’re buying the nuts for a regular snack or eating them just before a training session. | If I eat something shortly before an intense training session, I want to consider how it sits with me; around 50% of consumers prioritise timing and tolerance. |
| Ingredients and salt | Check the ingredients list and see whether salt, oil or flavourings have been added. | If I’m looking for an unsalted variety or one with a simple list of ingredients, I want to read the label on that exact pack; around 30% of consumers prioritise ingredients. |
| Quantity and storage | Compare the pack size with how much you eat and read the storage instructions. | If I don’t eat many cashews or like to alternate between varieties, I don’t want to open more stock than is practical; around 20% of consumers focus mainly on quantity and how they use their stock. |
Cashews aren’t automatically a suitable choice just before an intense run. Hardlopen.nl notes that a meal high in fat, fibre and protein may feel heavier when eaten closer to a run.
Think about when you’ll eat them first, and don’t automatically treat a regular snack as part of your pre-training strategy.
The preparation method doesn’t tell you everything about the ingredients. Unsalted, unroasted and made without added oil are different characteristics.
Read the ingredients list and nutritional information for the exact variety, and check separately whether salt or oil has been added.
