The effect that pineapple has on oral sex depends on how often you eat pineapple, the impact of other foods in your diet, your overall health, and other factors. In general, eating fruit causes bodily secretions to taste sweeter. Anecdotal evidence and a few small studies indicate pineapple may have the biggest effect.

If you stop to think about it, it's no big surprise that what you eat affects the way you taste. After all, the feed given to given to animals affects the flavor of the meat. So, it makes sense what you eat affects how you taste. No, we're not talking about how you would taste to cannibals! Rather, what you eat has impact on the taste of bodily secretions, including seminal and vaginal fluids.

There are a few studies on the topic and numerous blog posts sharing personal experiments. Two small studies include the pineapple sex test, conducted at, and a review of online data from the folks at the Kinsey Institute. The limited data finds both male ejaculate and female vaginal secretions are affected by pineapple. It doesn't seem to matter whether the pineapple is fresh, canned, or juiced. The effect is not noticeable immediately after eating a few bites of pineapple. Most respondents saw a definite effect after eating pineapple for several days. The effect relates in part to the way food affects mucus production and composition. Chemicals in foods you eat are found in most secretions, including perspiration and breast milk as well as semen and vaginal fluid.

Foods That May Make You Taste Sweeter (Or Not)

In addition to pineapple, there are other foods that reputedly change your body chemistry enough to alter the flavor of semen and vaginal fluid. These tend to be foods high in acidity or sugars and include:

  • Water
  • Liqueurs (but not so much alcohol as to cause dehydration)
  • Pineapple
  • Dried fruit
  • Fresh berries
  • Kiwi

Foods high in chlorophyll (wheatgrass, celery, parsley) got mixed reviews. Several websites recommended them, but they did not cite their sources and none of the bloggers who tested them out detected much effect. Another key factor is your hydration level. 

Just as some foods may make you taste better, others may have a negative impact, increasing bitterness. You and your partner may wish to limit:

  • Smoking
  • Coffee
  • Broccoli, cauliflower, asparagus and other Brassica sp.
  • High levels of preservatives in foods
  • Certain drugs (specifics were not given)
  • Onions, garlic, and other Allium sp. (believed to be related to sulfur compounds)

There were mixed reviews concerning fish, red meat, dairy, and beer. Anecdotally, it would appear that eating meat is not a negative factor, as long as a person's diet regularly includes fresh fruits and vegetables.

Foods That Affect How You Perceive Flavor

Your perception of flavor relies on chemoreceptors. Compounds in the foods you eat not only impact your secretions and chemical composition but your ability to taste chemicals.

The enzyme bromelain in pineapples is a protease that literally dissolves proteins in your mouth, causing a prickly sensation and limiting your ability to perceive flavors.

Sodium lauryl ether sulfate and sodium lauryl sulfate​ are ​surfactants in toothpaste that lower surface tension of fluid inside your mouth. This is great when you're brushing away bacteria, but the surfactants also wash away phospholipids that coat your tongue. The result explains why orange juice tastes incredibly vile if you drink it right after brushing your teeth. Incidentally, you'd get the same effect if you washed your mouth out with soap containing these common ingredients.

Artichoke, on the other hand, makes food taste sweeter. This results from a chemical reaction with the cynarine and chlorogenic acid in the plant. Cynarin inhibits your ability to taste sweet flavors, but the chemical is displaced by the next food you eat, automatically making it taste sweet.
