Along with several other types of nuts, almonds are a source of the sleep-regulating hormone melatonin. They are also an excellent source of magnesium, providing 19% of your daily needs in only 1 ounce. Consuming adequate amounts of magnesium may help improve sleep quality, especially for those who have insomnia. Magnesium’s role in promoting sleep is thought to be due to its ability to reduce inflammation. Additionally, it may help reduce levels of the stress hormone cortisol, which is known to interrupt sleep.
Almonds are often considered one of the best brain foods. Almonds nutrition is somewhat unique in that almonds contain riboflavin and L-carnitine, two key nutrients capable of positively affecting neurological activity and preventing cognitive decline. This is one reason why adults, especially the elderly, are encouraged to eat nuts several times per week — since they are associated with a reduction in the risk for inflammation that can cause brain disorders including dementia and Alzheimer’s disease.
Healthy fats and dietary fiber aid in weight loss because they help you feel full, which curbs overeating and unhealthy snacking. Although nuts are high in fat and calories, they prolong the feeling of satisfaction after you eat and keep your blood sugar more stable than low-fat meals do. Thus, you’re less likely to experience a roller-coaster of energy dips and food cravings. Studies, such as the Nurses’ Health Study, even show that almonds support a healthy metabolism. Also, people who frequently eat almonds and other nuts retain healthier body weights and lower rates of obesity over time compared to those who avoid nuts. Other studies show that when dieters eat almonds daily, they are less likely to over consume carbohydrates and more likely to reach and maintain a healthier body weight.
Almonds contain gamma-tocopherol, a type of vitamin E that acts as a powerful antioxidant, fighting free radical damage and oxidative stress that are linked to cancer. Many studies find a link between nut consumption and cancer prevention, including a reduced risk for colon, prostate and breast cancers.
Almonds are a great source of vitamin E and other antioxidants that nourish the skin and reduce signs of aging. Research finds that almonds nutrition contains high concentrations of catechin, epicatechin and flavonol antioxidants, including quercetin, kaempferol and isorhamnetin — compounds that fight skin cancer and damage by reversing oxidative stress from a poor diet, pollution and UV light exposure.
Almonds’ healthy fats, plus their ability to improve circulation, also help keep skin hydrated and better able to heal wounds.
Almonds are high in magnesium, which plays a key role in converting sugar to energy. They're also filled with fiber to keep your blood sugar levels even and protein to stave off hunger.
