Here’s Why Your Body Deserves A Handful Of California Walnuts Everyday

On National Walnut Day, we talk about the powerful health benefits of our favorite nuts and why you must ‘Think California’ when you ‘Think Walnuts’.

Since the 1950s, May 17 is celebrated as National Walnut Day, and this year’s no different. This day serves as a gentle reminder for one and all about the beautiful flavors, powerful health benefits, and versatility of walnuts. A day that deserves to be celebrated with at least a handful of walnuts, to acknowledge the fact that these are exceptionally nutritious and  why you should #ThinkWalnutsThinkCalifornia.

A Handful Of Walnuts = A Healthy You

Over three decades of research suggests that walnut, as part of a nutritious, balanced diet, is key to a healthy heart. Walnut is the only tree nut to contain a rich source of plant-based omega-3 ALA (2.5g per 28g), which not only helps maintain normal blood cholesterol levels but also plays a role in the prevention and reduction of heart disease.1,2

The brain-like appearance of the walnuts is indicative of the powerful connection that these nuts have with the brains, and how they improve cognitive functions.3 The wonder nut is an excellent source of good fats that are an important part of a healthy diet and may promote weight management. Research also suggests that walnuts may aid in aging healthily and support gut health (courtesy of good bacteria).4,5

Another key point to note is the role of walnuts in maintaining a healthy immune system, and our body’s healing and recovery, which is a necessity in today’s scenario. The Food Safety and Standards Authority of India (FSSAI)’s Eat Right During COVID-19 guidelines mentioned that foods with omega-3, zinc, selenium, protein, and vitamin B may aid optimal functioning of the immune system (as part of a balanced diet), and walnuts contain all these nutrients.6 Walnuts may also benefit people living with type 2 diabetes or metabolic syndrome.7

 Think Walnuts, Think California

Grown and harvested in the sunshine state of California, a handful of California walnuts (approx. 28g) contain 4g protein, 2g fiber, and 2.5g plant-based omega-3 ALA. And all these nutrients have proven to be beneficial for our heart, brain, and gut health. These walnuts are mildly sweet, crunchy, and creamy; and can be used in various ways to make beverages, appetizers, snacks, mains, and desserts.

California walnuts, a powerhouse of essential nutrients, are grown by multigenerational farmers with the best of resources – fertile soil and great sunshine, among other things. And they are processed and packaged under strict quality control standards to ensure the consumers receive nothing but the best quality produce.

Another important point to note is that these walnuts are cleaned and dried in their protective shells and dried to an ideal moisture level of eight percent, to ensure there’s no compromise on appearance, texture, or flavor during processing and packaging. These walnuts meet – and often exceed – the standards laid down by the Federal and state of California.
