Top 10 Foods and Drinks Highest in Fluoride

Fluoride is a mineral known for strengthening teeth and helping prevent dental cavities. (1) Since the amount of fluoride in foods can vary, it is added to public water supplies in some countries, including the United States.

According to the National Library of Medicine (NLM), the amount of fluoride you need depends on your body mass (weight). Children typically need 0.5mg (500mcg) per day, while adults need 3-4mg (3000-4000mcg) of fluoride each day. (2) For the adequate intake (AI) calculations below, a value of 4mg (4000mcg) is used.

Since consuming too much fluoride can have ill health effects, the NLM sets the upper limit at 10mg, or 10,000mcg. (2) This is just 2.5 times the adequate intake.

Fluoride can be found in a variety of different foods, including tea, coffee, shellfish, grapes (raisins, wine, grape juice), artificial sweeteners, sodas, potatoes, flavored popsicles, baby foods, broths, stews, and hot cereals made with tap water.

Sugary or carbonated drinks can lead to more tooth decay. Even if they contain significant levels of fluoride, they tend to have a net negative effect on dental health, due to the effects of the sugar they contain. (3)

For all these fluoride foods and drinks, if fluoride-fortified water was used in their creation, they will have even more fluoride. Below are the top 10 sources of fluoride, for more, see the extended list of fluoride-rich foods and drinks.
