Technically, peanuts are legumes, but since they literally have \u201cnut\u201d in their name and most of us put them in that category anyway, they were included in the study. Turns out, they produced the highest delta response, which can help with immunity, natural healing and deep sleep.<\/a><\/p>\n \n\tSo what is it about nuts that makes them so brain-friendly? Many of the nutrients in nuts contain antioxidant properties, Zenker explains, which \u201chelp lower inflammation<\/a> and combat oxidative stress.\u201d The polyunsaturated fats in nuts \u2014 especially the omega-3s in walnuts \u2014 have been linked to reduced brain inflammation, studies<\/a> have found. And, Zenker adds, \u201cVitamin E, magnesium, zinc, and selenium are essential micronutrients found in nuts that play important roles in nervous system function and antioxidant defense.\u201d<\/p>\n \n\tZenker says that walnuts are especially a standout, thanks to those omega-3s. \u201cOmega-3 is an essential fat that has potent anti-inflammatory benefits,\u201d she explains. That\u2019s important for your brain health, because \u201cneuroinflammation is one of the primary contributors to cognitive decline,\u201d Zenker says.<\/p>\n \n\tNuts also support brain health indirectly, Zenker adds, by promoting a healthy gut microbiome<\/a> (which has a major effect on your brain health via the gut-brain axis) and benefiting cardiovascular health, which improves blood flow and nutrient delivery to the brain.<\/p>\n \n\tOf course, nuts are also beneficial for the rest of your body; they are great for your heart, gut, brain, skin, immune, and metabolic health, Zenker says. And you can get those benefits with just a handful of mixed nuts a day \u2014 not too shabby for a quick health boost.<\/p>\n![\"Peptides,](\"https:\/\/www.sheknows.com\/wp-content\/themes\/vip\/pmc-sheknows-2020\/assets\/public\/lazyload-fallback.gif\")
