6 Reasons to Eat an Avocado

The avocado is an unusual fruit. Not only is it high in calories, but it is rich in fat too. Instinct suggests that a high-calorie and high-fat food would be bad for health, yet the humble avocado actually provides a host of wonderful health benefits.

There are dozens of varieties of avocados, split into three main categories—West Indian, Mexican and Guatemalan. Green and luscious, the flesh of the avocado is hard when it is harvested. As the fruit ripens, the flesh softens and its texture becomes butter-like. The Aztecs thought of avocados as an aphrodisiac, while Amazonian herbalists believe that they can treat gout.

1. A good source of nutrients

  • Protein—highest among fruits; about 2 g per 100 g (3.5 oz)
  • Fiber—about 6.7 g per 100 g; highest soluble fiber content of any fruit
  • Monounsaturated fatty acids—about 14.7 g of fats per 100 g, with two-thirds being healthful monounsaturated fats; unsaturated fatty acid content ranks only behind olives among fruits
  • Carbohydrates—about 8.5 g per 100 g, or more than 300 calories per avocado
  • B vitamins
  • Vitamin C
  • Vitamin E
  • Phosphorus
  • Potassium—about 500 mg per 100 g; one avocado matches two to three bananas
  • Zinc—regulates immune function, contributes to wound healing, senses of smell and taste
  • Folate—important for pregnant women, preventing dangerous spinal and brain birth defects; helps maintain proper nerve function
  • Lutein—helps prevent prostate cancer; prevents cataracts and age-related macular degeneration
  • Glutathione—potent antioxidant with anticancer properties
  • Oleic acid
  • Linoleic acid

2. Lowers cholesterol

Avocados, in particular its oleic acid content, may help lower cholesterol levels. One particular study that looked at persons with moderately high levels of cholesterol who consumed many avocados in their diet revealed significant reductions in total cholesterol and "bad" LDL cholesterol levels as well as an 11 percent increase in the "good" HDL cholesterol. Other research also showed the slight lowering of triglyceride levels.

Another way in which avocados help lower cholesterol levels is through the fiber they contain, which removes excess cholesterol from the body.

3. Boosts cardiovascular health

The high-potassium content in avocados helps lower high blood pressure, plus reduces one's risk of suffering from strokes and heart attacks.

Some research has also suggested that oleic acid could help reduce bodily inflammation, thus lowering the probability of atherosclerosis developing.

Further, folate could help lower heart disease risk by decreasing bodily levels of homocysteine, an amino acid which could damage blood vessels at elevated levels.

Vitamin E is also a heart-healthy vitamin, while lutein helps protect against hardening of the arteries.

4. Helps control diabetes

According to Abhimanyu Garg, MD, "monounsaturated fats improve fat levels in the body and help control diabetes." Researchers have found that diabetics who consumed a lot of carbohydrates tended to develop high levels of triglycerides, blood fats which could elevate heart disease risk. However, when some of these carbohydrates were replaced with fats, in particular the type found in avocados, triglyceride levels tended to go down.

5. Improves bone health

Avocado is a relatively good plant-based source of vitamin D, which helps the body turn calcium into bones.

Phosphorus in avocados is also an important part of the bones and teeth.

6. Relieves skin conditions

Avocado oil can be used topically to treat some types of dermatitis plus dry skin and wrinkles. Long-term use can help relieve eczema too. It can be applied directly to the affected areas.

Mashed avocados or its inner peel (retaining some green flesh) can also be rubbed on psoriasis patches to obtain relief.

5 People Calling Out EPA Acting Head Wheeler for Putting Polluters First

This week, people across the country are joining environmental leaders to speak out against the nomination of former coal lobbyist Andrew Wheeler to lead the the U.S. Environmental Protection Agency (EPA). As Scott Pruitt's hand-picked successor, Wheeler has continued to put polluters over people, most recently by using the last of his agency's funding before it expired in the government shutdown to announce plans to allow power plants to spew toxic mercury and other hazardous pollution into the air.

Wall Before Country Takes Mounting Toll on Americans Everywhere

By Rhea Suh

One month on, the longest and most senseless U.S. government shutdown in history is taking a grave and growing toll on the environment and public health.

Food inspectors have been idled or are working without pay, increasing the risk we'll get sick from eating produce, meat and poultry that isn't properly checked. National parks and public wilderness lands are overrun by vandals, overtaken by off-road joyriders, and overflowing with trash. Federal testing of air and water quality, as well as monitoring of pollution levels from factories, incinerators and other sources, is on hold or sharply curtailed. Citizen input on critical environmental issues is being hindered. Vital research and data collection are being sidelined.

All Coal-Fired Power Plants in Texas Found Leaking Toxins Into Groundwater

Power plants across Texas are leaching toxins into groundwater, according to new research. A report released this week from the Environmental Integrity Project found that all of the state's 16 coal-fired power plants are leaching contaminants from coal ash into the ground, and almost none of the plants are properly lining their pits to prevent leakage.

MLK National Park to Re-Open Despite Shutdown, Thanks to Delta

Hats off to Delta Air Lines. The company's charitable arm awarded the National Park Service an $83,500 grant to help reopen the Martin Luther King Jr. National Historical Park in Atlanta from Jan. 19 through Feb. 3 in honor of Dr. King's legacy.

The Atlanta-based airline was inspired to act after learning that some of the park's sites, including Dr. King's birth home, Ebenezer Baptist Church, Fire Station No. 6 and the visitor center, were closed due to the partial government shutdown, now on its 28th day, according to LinkedIn post from Delta Air Lines CEO Ed Bastian.
