Avocados are no longer just used in guacamole. Today, they’re a household staple across the United States and in other parts of the world.

Avocados are a healthy fruit, but they’re not the lowest in calories and fat.

Nutrition facts for avocados
Avocados are the pear-shaped fruit of avocado trees. They have leathery green skin and contain a single large seed called a stone. The Hass avocado is the most cultivated variety worldwide and the most common in the United States.
As they ripen, avocados turn dark green to black. They vary in size, with most avocados in grocery stores being medium-sized.
The suggested serving size is around one-fifth of a medium-sized avocado. Here’s a look at the number of calories and fat in avocados:
- 1 serving (1/5 of an avocado) contains 50 calories and 4.5 grams of fat
- 1/2 of an avocado (medium) contains 130 calories and 12 grams of fat
- 1 avocado (medium, whole) contains 250 calories and 23 grams of fat
Is the fat in avocados healthy?
Avocados are high in fat, but it’s not the saturated fat found in some full-fat dairy products, red meat, and most junk food. The American Heart Association (AHA) recommends limiting saturated fat intake to reduce the risk of heart disease.
However, a 2011 meta-analysis found no direct connection between saturated fat, heart disease, and stroke. It may be that trans fat, found in partially hydrogenated oils like margarine, plays a larger role. Even so, the AHA maintains its current guidelines.
Avocados contain only a trace amount of saturated fat. Most of the fat in avocados is monounsaturated fatty acids (MUFAs), which are thought to lower total cholesterol and “bad” cholesterol (LDL) while increasing “good” cholesterol (HDL).
Other health benefits of eating avocados
Avocados may play a role in cancer prevention. Studies show that the phytochemicals in avocados may inhibit the growth of and induce cell death in precancerous and cancerous cell lines.
Avocados are a good source of dietary fiber, which helps prevent constipation. One serving contains 2 grams of fiber. Fiber also helps keep you fuller longer, potentially preventing overeating.

Overweight and moderately obese adult study participants who ate about half of a Hass avocado at lunch felt full for three to five hours afterward. Their blood sugar levels remained more stable compared to participants who ate an avocado-free lunch.
A 2013 report found that eating avocados is associated with improved overall diet quality, nutrient intake, and a reduced risk of metabolic syndrome.
Vitamins and minerals in avocados
Red meats may promote inflammation in the body, partly due to their saturated fat content. Inflammation is another potential risk factor for cardiovascular disease. Avocados may help reduce inflammation.
A small 2012 study found that eating half of a Hass avocado with a burger, instead of eating a burger alone, helped reduce the production of substances that promote inflammation in the body.
Research suggests avocados may help your body absorb specific nutrients from other foods.
Avocados are cholesterol-free, sodium-free, and low in sugar. They are an abundant source of many vitamins and minerals, including:
- Vitamin A
- Vitamin K
- Vitamin C
- Vitamin E
- Iron
- Potassium
- Zinc
- Manganese
- B vitamins (except vitamin B12)
- Choline
- Betaine
- Calcium
- Magnesium
- Phosphorus
- Copper
- Folate
Should you eat avocado seeds?
You may have heard about the benefits of eating avocado seeds. Emerging research suggests that the seeds may have antimicrobial and anti-inflammatory properties.
These properties may help some health conditions, but most research used avocado seed extract, not whole, fresh avocado seeds. It has not yet been established if avocado seeds are safe to eat.

Summary
Avocados are healthy, but that doesn’t give you carte blanche to eat them nonstop. Despite their impressive nutrition profile, eating too many can lead to weight gain.
When enjoyed as part of an otherwise healthy diet, avocados may help you lose weight. Don’t eat avocados in addition to unhealthy foods. Instead, replace unhealthy foods in your diet, like sandwich spreads, with avocados.
