How do walnuts profit cognitive well being? 

Amongst nuts, walnuts stand out as your best option for supporting mind well being and stopping dementia as a result of they’re one of many few tree nuts wealthy in omega-3s (particularly alpha-linolenic acid), polyphenols, and antioxidants. These compounds assist scale back irritation and oxidative stress — a state the place free radicals outnumber antioxidants, resulting in cell injury — two main components in cognitive decline, says Christina Ni, MD, a board-certified psychiatrist and interventional psychiatry medical director with Mindpath Well being.

The nut additionally incorporates a variety of flavonoids (plant pigments), which act as potent plant compounds that scale back mind irritation, defend in opposition to cell injury, and improve cognitive capabilities like reminiscence and processing pace, says Ryan Sultan, MD, a double-board-certified psychiatrist and medical director at Integrative Psych of Manhattan. Research assist this, discovering {that a} greater consumption of flavonoid-rich meals is related to a decrease threat of cognitive decline and reminiscence issues.

Moreover, analysis exhibits that walnuts can increase blood stream to the mind, assist mind cell exercise and signaling, and enhance neuroplasticity—the mind’s capability to restore itself. Ni credit these results to improved cognitive operate and safety in opposition to age-related psychological decline.

Walnuts additionally include the next brain-boosting vitamins, in accordance with Ni.

• Polyunsaturated fat and protein: Vitamins that present power and useful fat that contribute to wholesome mind cells.

“Primarily, these vitamins and compounds work collectively to advertise wholesome mind signaling and performance, gasoline power, scale back irritation, lower oxidative stress, and improve blood stream, and collectively, they contribute towards neuroprotection (mind safety) which retains the mind sharp, resilient, and well-nourished as individuals age,” Ni says.

Why are the cognitive advantages of walnuts better when eaten within the morning?

In a fasted morning state, the mind is operating on empty, so it primarily is determined by its first provide of glucose (a easy sugar that serves because the physique’s major power supply). On this case, Sultan says, “The well being advantages seem stronger when walnuts are consumed within the morning as a result of they supply a gradual provide of glucose as a substitute of a spike and crash, and these delayed results overlap with peak work and research hours noon.” 

In different phrases, the physique is ready to soak up essentially the most gasoline within the morning. “The best way the physique digests walnuts is similar mechanism regardless of the time of day, however the physique responds in a different way relying on circadian rhythm, so within the morning, insulin sensitivity is greater, and the physique is primed to make use of vitamins for power and mind operate,” Bianchini explains. “At evening, the physique is winding down and extra prone to retailer vitamins quite than actively use them.”

There’s no particular higher restrict talked about on this research, however Ni recommends not exceeding 2 ounces of walnuts per day (about 14 complete walnuts), as extra energy could outweigh the advantages. Walnuts are additionally excessive in fiber, so consuming too many too rapidly may cause digestive discomfort, similar to bloating, cramping, or gasoline. 

Moreover, these with a nut allergy ought to keep away from walnuts utterly, and anybody with pancreatitis or digestive points could wish to restrict their consumption, since high-fat meals like walnuts can worsen signs, Ni says. And though uncommon, individuals on blood-thinning drugs must also speak to their physician earlier than consuming walnuts usually, as a result of walnuts can improve the danger of bleeding when consumed in excessive portions, she provides.

Consistency is essential for optimum well being advantages, so Ni recommends consuming walnuts roughly 5 to seven instances per week. It’s additionally higher to decide on uncooked, unsalted walnuts, because the added sodium and sugar in salted or candied choices could outweigh the well being advantages.
