Avocados are a stone fruit with a creamy texture that grow in warm climates. Their potential health benefits include improving digestion, decreasing risk of depression, and protection against cancer.
Also known as an alligator pear or butter fruit, the versatile avocado is the only fruit that provides a substantial amount of healthy monounsaturated fatty acids (MUFA). Avocados are a naturally nutrient-dense food and contain nearly 20 vitamins and minerals.
This MNT Knowledge Center feature is part of a collection of articles on the health benefits of popular foods. In the article, we take an in-depth look at the possible health benefits of eating avocados as well as a nutritional breakdown. To maintain balance, we will also look at the possible health risks of consuming avocados.
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.
1. Avocados are nutrient rich
According to the USDA National Nutrient Database, one serving (one-fifth of an avocado, approximately 40 grams) contains:
almost 6 grams of fat
3.4 grams of carbohydrate
less than a gram of sugar
almost 3 grams of fiber
Avocados are a great source of vitamins C, E, K, and B-6, as well as riboflavin, niacin, folate, pantothenic acid, magnesium, and potassium. They also provide lutein, beta-carotene, and omega-3 fatty acids.
Although most of the calories in an avocado come from fat, don't shy away! Avocados are full of healthy, beneficial fats that help to keep you full and satiated. When you consume fat, your brain receives a signal to turn off your appetite. Eating fat slows the breakdown of carbohydrates, which helps to keep sugar levels in the blood stable.
Fat is essential for every single cell in the body. Eating healthy fats supports skin health, enhances the absorption of fat-soluble vitamins, minerals, and other nutrients, and may even help boost the immune system.
2. Healthy for the heart
Avocados contain 25 milligrams per ounce of a natural plant sterol called beta-sitosterol. Regular consumption of beta-sitosterol and other plant sterols has been seen to help maintain healthy cholesterol levels.
3. Great for vision
Avocados contain lutein and zeaxanthin, two phytochemicals that are especially concentrated in the tissues in the eyes where they provide antioxidant protection to help minimize damage, including from ultraviolet light.
As the monounsaturated fatty acids in avocados also support the absorption of other beneficial fat-soluble antioxidants, such as beta-carotene, adding avocados to your diet may help to reduce the risk of developing age-related macular degeneration.
4. Osteoporosis prevention
Half of an avocado provides approximately 25 percent of the daily recommended intake of vitamin K.
This nutrient is often overlooked, but is essential for bone health.
Vitamin K is often overshadowed by calcium and vitamin D when thinking of nutrients important for maintaining healthy bones, however, eating a diet with adequate vitamin K can support bone health by increasing calcium absorption and reducing urinary excretion of calcium.
