Is Avocado Anti-Inflammatory? What Feeding Trials Measured

Avocado shows up on almost every anti-inflammatory food list. We read the trials that actually tested it, and the largest one tells a quieter story.

The short answer

Not clearly. Is avocado anti-inflammatory? In one 12-week trial of 93 adults, CRP was lower after eating avocado. But the largest trial, with 1,008 people eating one avocado a day for 6 months, found no change in CRP. Avocado does have better-tested benefits for blood fats.

Why avocado made the list

Avocados pack a lot into one fruit. They are rich in unsaturated fats and fiber. They also carry antioxidants, the plant compounds that soak up some of the damage from cooking and digesting food.

That mix is why avocado lands on so many "anti-inflammatory foods" lists. Diets high in unsaturated fat and fiber are linked to lower heart and metabolic risk. So it makes sense to guess that avocado would calm inflammation too.

A guess is not a test, though. To know, someone has to feed people avocados and measure what happens in their blood. The usual measure is CRP (C-reactive protein), a protein your liver makes more of when inflammation is running high. Another is IL-6, a signal your immune cells send to switch inflammation on.

Does avocado reduce inflammation in the body?

Two good trials have tried to answer this. They disagree.

In the largest trial, an avocado a day for 6 months did not move CRP.From a 2022 randomized trial in J Am Heart Assoc

The first ran for 12 weeks in 93 adults who were overweight and had insulin resistance, an early step toward type 2 diabetes. One group swapped avocado in for carbohydrate foods. The other swapped in a low-fat, low-fiber food with the same calories. At 12 weeks, CRP was lower in the avocado group. Body weight did not change in either group, so weight loss does not explain it.

The second trial is much bigger. The HAT trial gave 1,008 adults with a large waist one large avocado a day for 6 months, and compared them with people on their usual diet. It found no difference between the groups in hsCRP, the sensitive version of the CRP test. The researchers summed it up plainly: one avocado a day had "minimal effect" on heart and metabolic risk factors.

When a small trial and a big one disagree, the big one usually deserves more weight. That is why our grade stays at Emerging.

What about one avocado-heavy meal?

Some studies test a single meal. In a 2013 pilot trial, 11 healthy people ate a hamburger patty, either alone or with 68 grams of avocado. After the burger alone, IL-6 rose at 4 hours. When avocado was added, no rise was seen.

That sounds promising, but it was 11 people and one meal. A 2018 trial with 31 overweight adults tried breakfasts with no avocado, half an avocado or a whole one. IL-6 was not different among the meals. Blood sugar and insulin after the meal were lower with avocado.

What large studies of everyday eating show

Trials are short. So researchers also look at what people already eat. In a study of 5,794 adults from several ethnic groups, people who ate avocado or guacamole often did not have lower inflammation markers than people who rarely ate it, once other habits were taken into account. That was a snapshot in time, so it can only show a link or the lack of one.

Reviews that pool the trials say the same. A 2018 review of 18 studies found no difference in hsCRP in the 2 studies that measured it. A 2024 review of 9 trials graded its avocado findings low to very low certainty.

Can avocado raise inflammation in the body?

We found no trial where avocado raised inflammation markers. In the HAT trial, 1,008 people ate an avocado a day for 6 months with no difference in hsCRP. A 2024 review also found that eating avocado did not harm body weight.

Where avocado does earn its place

The clearer story is about blood fats. In a 2026 feeding trial, 42 adults with high triglycerides ate an average American diet, and in another 3-week period, the same diet with one avocado a day replacing solid fats and added sugars. Neither the people nor the researchers knew which version was which. The avocado version lowered triglycerides by 17.4% and non-HDL cholesterol by 4.65%.

In a 2026 trial of 82 adults with prediabetes, a daily avocado plus a cup of mango for 8 weeks improved how well blood vessels widened. Inflammation markers were generally not different between the diets.

And in an 8-week trial with 44 adults with obesity, a whole eating pattern built on fruit, avocado, whole grains and trout lowered the activity of several inflammation genes, compared with a usual diet high in saturated fat and processed carbs. Avocado was only one part of that menu, so the result belongs to the pattern, not the fruit.

The bottom line

The burger study, the 12-week swap, the 1,008 people who ate an avocado a day for half a year: put together, they do not add up to an anti-inflammatory food. They add up to a good fat that can stand in for worse ones. That is a real benefit, and it is enough. Slice it onto the plate in place of the butter or the white toast, and let the rest of the plate do the cooling.

Common questions

Is avocado good for an anti-inflammatory diet?

It fits well, but mostly as a swap. In an 8-week trial, a diet built on fruit, avocado, whole grains and trout lowered inflammation gene activity compared with a usual diet high in saturated fat and processed carbs. On its own, one avocado a day for 6 months did not change hsCRP in 1,008 adults.

Can avocado raise inflammation in the body?

We found no evidence that it does. In the HAT trial, adults who ate one large avocado a day for 6 months showed no difference in hsCRP from those on their usual diet. In a study of 5,794 adults, avocado eaters and non-eaters had similar levels of inflammation markers.

How much avocado did the trials use?

Most used one avocado a day. The 2026 feeding trial used about 180 grams a day, roughly 300 calories. The HAT trial used one large avocado a day for 6 months. The single-meal studies used half an avocado, 68 grams, or a whole one, 136 grams.

Does avocado lower CRP?

Results are mixed. In a 12-week trial of 93 adults with insulin resistance, CRP was lower after the avocado diet. But in the much larger HAT trial, hsCRP did not change. A 2018 review found no difference in hsCRP in the 2 studies that measured it.
