Avocado Nutrition Facts and Benefits

Harvard Health Publishing defines the glycemic index values of foods as a marker of how much a food will affect your body's blood glucose levels. According to a June 2015 study in the Journal of Ethnic Foods, avocado's glycemic index value is about 40. Avocado's GI value is in part due to the macronutrient content of this fruit.

According to the USDA, 100 grams (3.5 ounces) of Hass avocado has 200 calories, 16.7 grams of fat (3.3 grams come from saturated fat) and 3.3 grams of protein. Every 100 grams of avocados also have 10 grams of carbohydrates, 6.7 grams which come from dietary fiber.

Of course, there are many different types of avocados. Your avocado's macronutrients may differ based on the exact type you choose to consume. California and Florida avocados can be quite different, for instance.

Avocados are also rich in a variety of vitamins and minerals. The USDA says that 100 grams of avocados will provide you with:

  • 10 percent of the daily value (DV) for potassium
  • 6 percent of the DV for manganese
  • 7 percent of the DV for magnesium
  • 6 percent of the DV for zinc
  • 21 percent of the DV for copper
  • 6 percent of the DV for vitamin B1 (thiamin)
  • 11 percent of the DV for vitamin B3 (niacin)
  • 28 percent of the DV for vitamin B5
  • 15 percent of the DV for vitamin B6
  • 20 percent of the DV for vitamin B9 (folate)
  • 11 percent of the DV for vitamin C
  • 14 percent of the DV for vitamin E
  • 18 percent of the DV for vitamin K

You can also find small amounts of other essential nutrients in avocado, including vitamin A, vitamin C, selenium, iron and calcium.

Avocado's Glycemic Index Value

According to the Mayo Clinic, glycemic index values are typically divided into three main categories: low, medium and high GI values. Low GI foods have values of 55 or less, medium GI foods have values that range between 56 and 69, and high glycemic index foods have values of 70 or more.

Avocado's GI value of 40 means that it falls into the low category. However, according to a May 2013 article in the journal Critical Reviews in Food Science and Nutrition, avocado pear's glycemic load and glycemic index are estimated to be about zero. This is because there are very few sugars in avocado (half of a Hass avocado has just 0.2 grams of sugar).

The primary sugar in avocado, D-mannuheptalose, is thought to act more like beneficial phytochemical than a sugar. In fact, this review even reported that D-mannuheptalose thought to help support weight management and regulate blood glucose levels.

In November 2013, the Nutrition Journal published the results of a small, 26-person trial that also supported these findings. Trial participants were found to experience increased satiety after eating half an avocado with their lunch.

Including half an avocado in these participants' meals helped prevent spikes in blood sugar. It even helped reduce blood sugar levels in hours following the meal. Ultimately, avocado's GI value and these potential health benefits mean that this fruit's consumption may be particularly beneficial for diabetics, as well as other people with metabolic issues.
