Fruits That Contain Salicylic Acid

Salicyclic acid is a colorless organic acid. The acid is the basic form of aspirin and is thought to play a role in protecting the heart and reducing inflammation. It is also found in some topical skin products. Fruits and vegetables are natural sources of salicyclic acid, some containing higher amounts than others. People with an allergy to aspirin should avoid foods containing salicyclic acid.

Berries

• Blackberries, raspberries and blueberries are among the highest providers of salicyclic acid. According to a study by Oregon State University, raspberries provide a whopping 5 mg of salicyclic acid per 100 g of fruit, while blackberries provide 1 mg per 100 g. Other "super providers" are apricots, dates and raisins. Interestingly, fresh grapes have a lower salicyclic acid content than when dried, with red grapes having a higher content than green grapes.

Tomatoes

• Tomatoes are classified as a fruit, and according to Wageningen University they have the same salicyclic content as blackberries: 1 mg per 100 g. An Italian study in 2008 showed that organic tomatoes have higher levels than nonorganic, and a report published in 1981 in the "Journal of Food Sciences and Agriculture" states that canned tomatoes have higher levels of salicyclic acid than fresh tomatoes. It is thought that the heating process in producing canned tomatoes may contribute to the rise in the amount of acid, but this is not definite.

No Lemons

• Lemons, mangoes and passion fruit will not boost your salicyclic acid levels, according to Food-Info. Kiwis, lychees, plums and watermelon have moderate amounts. Apart from eating berries, which are more seasonal in some areas and not always available, eating a Granny Smith apple is one of the best ways to increase your intake of salicyclic acid. Some nonfruit, high-content sources are almonds, peanuts and water chestnusts, and spices such as curry powder, oregano, paprika and mustard.
