To make sure your California walnuts stay fresh as long as possible, keep them in an airtight container in a cold place and avoid exposing them to warm temperatures for long periods of time. Pop them in the fridge if you plan to use them within a month, or stash them away in the freezer if you want to keep them for longer. Remember to keep them away from foods with strong odours, as walnuts can absorb the flavours of other foods. Walnuts can be stored in their original, sealed packaging – but once you open the bag, you should transfer them into an airtight container to maintain freshness.

I am diabetic. Can I eat walnuts?
Yes! We support the position of Diabetes UK, which is that people with diabetes should follow the same healthy eating guidelines as recommended for the general population. This means they should follow a diet that is low in fat (especially low in saturated fat), low in added sugars and salt-containing foods, with meals based on starchy, wholegrain carbohydrates and plenty of fruit and vegetables. California walnuts can contribute to this healthy, balanced diet. For tailored advice on making dietary and lifestyle changes to help you manage your diabetes, contact your GP or a healthcare professional (preferably a state-registered dietitian).
Are walnuts low GI?
Walnuts contain very small amounts of carbohydrates (3.3g per 100g of product) and have a low glycaemic index (GI) as a result (typically between 0 and 24). This means that they are broken down slowly and release glucose into the bloodstream in a more gradual manner, which is particularly helpful to people with Type 2 diabetes. The glycaemic load for walnuts is also very low (typically 0-1).
What is the calorie content of walnuts?
There are 206 calories in a 30g handful of walnuts.
Is the fat in walnuts healthy?
In a nutshell, yes. Walnuts are high in heart-healthy unsaturated fats. This is great news, as current UK dietary guidelines recommend the majority of our fat intake is of the unsaturated kind (as opposed to the less healthy saturated kind). A generous 83% of a walnut’s fat content is unsaturated. Walnuts are also a rich source of the essential omega-3 fatty acid ALA (alpha-Linolenic acid), which can deliver some big health benefits. Read more on our good fats page.
Are all omega-3 fatty acids the same?
No. There are three different types of omega-3 fatty acid: EPA (eicosapentaenoic acid), DHA (docosahexaenoic acid) and ALA (alpha-Linolenic acid). You’ll find EPA and DHA in cold-water fatty fish, such as salmon, whereas ALA is found in plant-based foods, including walnuts. Find out more on our good fats page.
How do you roast walnuts?
