Most of its calories are fat
A whole medium avocado has more than 20 grams of fat, about four times as much as a large egg. A third of an avocado, the usual serving on a label, has about 8 grams.
The scores
How GallDiet scores avocado, from highest to lowest.
Each number is the average GallDiet score, out of 100, for that kind of food or meal among people who have gallstones and still have their gallbladder.
Avocado on its own or on plain toast
around 80Avocado, all meals
low 70sAvocado in a bigger meal
high 60sAvocado oil products
mid 50sThe labels describe the score, not your health: 85 and up is a high score, 71 to 84 is Caution, 31 to 70 is Moderate risk and 30 or less is High risk. Guacamole and avocado toast with egg are not listed on their own because fewer than 10 people have scanned each one so far. This is the smallest sample of any food page here, so read the numbers as a rough guide.
Why the scores differ
A healthy food that is still mostly fat.
GallDiet gives it a mild caution
The fat in avocado is mostly unsaturated, the kind usually described as healthy. GallDiet's score is led by how much fat a food has, so avocado loses some points, but fewer than cheese, butter or fried food.
What the score leaves out
GallDiet does not know your portion. Two slices on a salad and a whole avocado on toast get the same deduction, though the fat is very different. With avocado, the amount tells you more than the score does.
No gallbladder
Avocado after gallbladder removal.
GallDiet scores meals differently for people who have had their gallbladder removed. Fewer people in that group have scanned avocado, so treat these numbers as a rough guide.

Your own answer
An average can't tell you how your body will react.
The same food is fine for some people with gallstones and a trigger for others. These scores show the pattern across many people, not what will happen on your plate.
GallDiet scores your own meal from a photo, a barcode or a typed name, checks it against the triggers you have saved, and keeps a record of what you ate before each bad day.
About these numbers
Where the scores come from.
The scores on this page are averages of what GallDiet gave to meals its users scanned or typed in, up to October 13, 2026. A group of meals is shown only when at least 10 different people scanned it, and every number is rounded.
A GallDiet score starts at 100 and loses points for common gallstone triggers in the meal, mostly fat. It does not know your portion size, your medical history or how your body reacts.
GallDiet does not diagnose, treat, prevent or cure gallbladder disease or any medical condition. Use these scores alongside advice from your doctor or dietitian, not in place of it.
Medical context: public guidance from the NIDDK covers eating, diet and nutrition for gallstones. If you have severe pain, fever, vomiting, jaundice or chest pain, seek medical care immediately.
FAQ
Common questions about avocado and gallstones.
Can I eat avocado toast with gallstones?
Avocado on its own or on plain toast averages around 80 out of 100 in GallDiet, across 16 people with gallstones. Adding egg, cheese or bacon lowers the score, because each is counted as a trigger of its own.
Is avocado high in fat?
Yes. A whole medium avocado has more than 20 grams of fat, about four times as much as a large egg. Most of it is unsaturated. GallDiet's score looks at how much fat a food has, so avocado gets a mild caution even though its fat is the kind usually described as healthy.
How much avocado can I eat with gallstones?
GallDiet cannot answer that. Its score does not change with portion size, so two slices and a whole avocado score the same. A third of an avocado has about 8 grams of fat and a whole one more than 20, so the amount makes a real difference to the fat in the meal. Your doctor or dietitian can advise you on amounts.
Is guacamole OK with gallstones?
Only 5 people with gallstones have scanned guacamole in GallDiet, which is too few to publish an average. Guacamole is mostly avocado, and the chips it usually comes with add fat of their own.
Is avocado oil OK with gallstones?
Avocado oil products, such as bottled oil, cooking spray and avocado oil mayonnaise, average in the mid 50s out of 100 in GallDiet, across 14 people. Oil is pure fat, so it scores lower than the fruit.
Does avocado cause gallbladder attacks?
Some people with gallstones find that avocado sets off their symptoms and others eat it without any trouble. An average score cannot tell you which group you are in. Keeping a record of what you ate before each bad day is the practical way to find out. If you have severe pain, fever, vomiting or yellowing skin or eyes, seek medical care.
Can I eat avocado after gallbladder removal?
Among GallDiet users who have had their gallbladder removed, meals with avocado average in the high 70s out of 100, across 13 people. That is a small group, so treat the number as a rough guide and follow the advice your surgeon or dietitian gave you.
Where do these numbers come from?
They are averages of the scores GallDiet gave to 60 scans from 43 people who have gallstones and still have their gallbladder. A group is shown only when at least 10 different people scanned it. The scores are estimates based on common gallstone triggers, mainly fat, and they do not change with portion size. They are not medical advice.
