Eating a diet that contains plenty of fruits and vegetables of all kinds has long been associated with a reduced risk of many lifestyle-related health conditions. Numerous studies have found that a predominantly plant-based diet that includes foods such as avocados can help to decrease the risk of obesity, diabetes, heart disease, and overall mortality while promoting a healthy complexion and hair, increased energy, and overall lower weight.
Avocado reduces signs of aging. The first signs of aging usually appear on the skin. Some studies have shown that consuming healthful fats, such as those found in avocados, can help the skin to retain its elasticity. However, researchers have yet to address whether applying avocado oil to the skin has the same effect. Also it treats sunburned skin. The antioxidants in avocado oil may help to ease the symptoms of a sunburn. According to a 2011 review, the vitamin E, beta carotene, vitamin D, protein, lecithin, and essential fatty acids in the oil can support healing and soothe the skin. Other small studies have shown that consuming avocados may help to protect the skin from harmful UV radiation. When left on for short periods of time and rinsed off with warm water, avocado oil can keep skin hydrated without leaving an oily residue. This may reduce the risk of acne.
The antioxidants and vitamins in avocado oil may help to heal the dry, irritated, and flaky skin associated with eczema and psoriasis. A person with a skin condition may wish to test a patch of skin first, to ensure that the oil does not trigger or aggravate their symptoms.
