We all prioritize physical health, but what about our brains? Research indicates cognitive function can decline as early as age 45. Luckily, a simple snack might offer some protection: cashews.
Cashews are a popular choice in the United States, ranking fourth behind mixed nuts, peanuts, and almonds. But beyond their taste, cashews offer a nutritional profile packed with benefits. A single ounce of dry-roasted, unsalted cashews provides magnesium, phosphorus, potassium, and protein. They're also a good source of B vitamins, crucial for healthy brain function.
How Cashews Support Brain Health
B vitamins play a vital role in nearly every aspect of brain function. Studies show that B vitamin deficiencies can lead to cognitive decline. Regular cashew consumption can help ensure you're getting enough of these vital nutrients through your diet.
Research suggests cashews may even offer protection against neurological damage. A study on rats showed that a cashew-rich diet could protect against neuron damage caused by cisplatin, a chemotherapy drug known to impact cognitive function. This suggests that cashews might help mitigate some of the cognitive side effects associated with certain medical treatments.
Cashews and Anxiety: A Surprising Connection
Studies indicate that cashews may help reduce anxiety, particularly anxiety associated with a high-fat diet. Overconsumption of high-fat foods can negatively impact brain function and increase anxiety levels. Cashews, rich in unsaturated fatty acids, have been shown to support healthy brain development and potentially reduce anxiety and depression symptoms. Research on rats found that cashew flour consumption counteracted the anxiety-inducing effects of a high-fat diet in rodents with high cholesterol.
Important Note About "Raw" Cashews
Commercially sold cashews are safe to eat. Truly raw cashews contain urushiol, a toxic compound that needs to be removed through heating. Cashews labeled "raw" have been processed without additives but have still been heated.
