The vegetable in question is the artichoke, and the fiber gap between it and a plum is not close. Raw artichoke carries 5.40 grams of dietary fiber per 100 grams, according to the USDA FoodData Central entry for artichokes. Raw plum, a fruit often praised for gut benefits, carries just 1.40 grams per 100 grams.
That is close to a four-fold difference in fiber density between two produce items that most shoppers would guess were in the same league.
The gap matters because Americans are not close to hitting daily fiber targets. NHANES data compiled by the National Center for Biotechnology Information put the average daily intake at 16 grams, with men at 18 grams and women at 15.
The Institute of Medicine's Adequate Intake is 25 grams for women aged 19 to 50 and 38 grams for men in the same range, and an NIH-published review estimates that around 95 percent of American adults and children fall short.

Where the fiber in an artichoke actually goes
A large portion of artichoke fiber is inulin, a soluble fiber that the human gut cannot digest but that feeds resident bacteria. A randomized controlled trial in adults with type 2 diabetes, published in the European Journal of Nutrition in 2020, found that inulin-type fructans produced significantly higher fecal concentrations of total short-chain fatty acids and shifted the microbiota toward Bifidobacterium adolescentis.
Short-chain fatty acids are what beneficial bacteria produce when they ferment fiber, and they are linked to gut lining health and lower inflammation.
The Cleveland Clinic, in a dietitian-reviewed explainer with registered dietitian Beth Czerwony, notes that a large artichoke carries about 9 grams of fiber. That is more fiber than a full cup of prunes.
The cholesterol signal from artichoke leaf extract
The vegetable's leaf extract has been studied on its own. A systematic review and meta-analysis by Sahebkar and colleagues, published in Critical Reviews in Food Science and Nutrition in 2018, pooled 9 randomized controlled trials with 702 participants.

Artichoke extract supplementation was associated with lower total cholesterol by a weighted mean of 17.6 mg/dL, lower LDL cholesterol by 14.9 mg/dL, and lower triglycerides by 9.2 mg/dL, compared with placebo.
The effects are modest and come from concentrated extracts rather than the vegetable on a plate, so the finding does not translate directly into an eating recommendation. Readers on cholesterol-lowering medication should talk with their doctor before adding a supplement, since interactions and dosing are not something a food article can settle.
The signal does, however, help explain why interest in artichoke keeps returning in the cardiometabolic literature.
Making it a weekly habit
Preparing a whole artichoke intimidates most home cooks, which is one reason the vegetable rarely leaves the restaurant menu. The workaround sits on the same aisle as canned tomatoes. Jarred and canned artichoke hearts keep most of the plant's fiber and can go into salads, pasta, grain bowls, pizza and dips without any trimming.

For readers watching cholesterol through diet, artichoke joins a short list of everyday foods with published trial data behind them, including oats and garlic.
A single large artichoke covers roughly a third of the daily fiber target for adult women and close to a quarter for adult men.
