Next to fruits and granola bars, nuts are the most underrated nutritious snack. Accounting for less than eight percent of our daily antioxidant intake, studies report less than 40 percent of Americans eat nuts today. That's just nuts — especially when Harvard discovered a handful is a key in helping you live longer.
We know they're packed with protein, fiber and unsaturated fats, but it should also be recognized that they're a phenomenal snack that aid in a glowing, more smoother looking complexion. It's true! And we can give thanks to the vitamins and minerals, like copper, zinc, vitamin A, C, and E packed in each little nut that promote a healthy collagen production.
As we head into autumn and look for ways to keep our skin looking fresh, integrate nuts into meals or snacks for a glowing complexion that will improve the signs of aging.
Slightly bitter in flavor, these brain-friendly nuts are known best for being inflammation fighters thanks to its omega-3 fats. However, the journal Nutrients suggests a handful of these mood-busting nuts can help reduce stress and boost vitamin B levels, which is particularly great for your skin. Not only does vitamin B keep wrinkles and fine lines away, but its combination with zinc and vitamin E help to balance blood sugars, which support insulin function. When insulin spikes, this causes distressed skin and leads to acne or a reduction in collagen production.
Don't reserve chestnuts just for Christmas — eat them year round because they're the only nut packed with vitamin C. The National Institute of Health suggests a quarter cup of chestnuts serve up an astonishing 30 percent of the recommended daily allowance. But how does vitamin C aid in a clear complexion? Registered dietician, Gale Malesky shares in his book, Nature's Medicine that C is essential for the body to produce collagen and elastin — connective tissues that keep vein walls strong and flexible. Not only does it prevent collagen breakdown, but it also improves immune system function, which in turn helps heal broken capillaries for clearer skin.
From salads to ice cream, almonds are perfect on everything and are packed with protein, essential fatty acids and fiber. But as an added bonus, they're also the best natural anti-inflammatory as they reduce swelling and irritation.

A study in the Journal of Nutrition found almonds contain a high concentration of compounds that fight skin cancer and reverse the damage of oxidative stress caused by a poor diet, pollution and UV light exposure.
Not only are pistachios ideal for weight control, but they're also filled with heart-healthy fats that promote a happy cholesterol.

Founder of the paleo diet movement, Loren Cordain writes in his book The Dietary Cure for Acne that cashews are high in acne-fighting nutrients. While a diet consisting of primarily meat, vegetables, fruits and nuts help reduce the inflammation of acne, Cordain states cashews are one food that helps the most. High in selenium, these minerals act as an antioxidant with vitamin E, hydrate skin and reduce inflammation, like scarring. Moreover, the presence of zinc promotes immune function for healing and cell growth that can renew infected or damaged acne zones.

While they have also been said to fight certain cancers, these rich in flavor nuts are renowned for aiding in weight loss.
