The Acidity of Chocolate and How It Affects Health
With its rich flavor and smooth, melt-in-your-mouth texture, chocolate is one of the world's most beloved foods. But how does the acidity of chocolate impact your health, especially if you have issues like acid reflux or heartburn?
Here's a detailed look at the pH and acidity of different types of chocolate, and how chocolate may affect acid reflux and digestion.
The Cocoa Bean
All chocolate starts from the cocoa bean, which comes from the cacao tree. Cocoa beans have a pH ranging from 5.3 to 5.8, placing them in the acidic category.
However, the acidity of finished chocolate products varies based on how the cocoa beans are processed and what other ingredients are added.
Raw Cacao and Cacao Powder
Raw cacao is the least processed form of chocolate. Cacao powder is raw cacao with the fatty cocoa butter removed. Both raw cacao and cacao powder retain their natural acidity.
Raw cacao nibs register a pH between 5.3 and 5.8. Natural cocoa powder falls around 5.5 to 6.0 on the pH scale, classifying these ingredients as acidic.
Dark Chocolate
Dark chocolate retains more of the cocoa bean's natural acidity than milk or white chocolate. The cacao percentage also impacts acidity levels.
Higher cacao dark chocolate, from 70% to 100%, rates from 5.5 to 6.0 on the pH scale. Dark chocolates with 50% to 69% cacao fall between 6.0 and 6.5 pH.
Milk Chocolate
The dairy milk used to make milk chocolate has a neutralizing effect on acidity. Milk chocolate typically registers from 6.5 to 7.0 pH.
However, sensitivity varies by individual. Those highly sensitive to acid may still experience reflux symptoms from milk chocolate's acid content.
White Chocolate
White chocolate has no cocoa solids, only cocoa butter. With a pH between 6.5 to 7.0, white chocolate is the least acidic chocolate option.
However, white chocolate is high in fat, so large amounts may still provoke acid reflux in susceptible people.
Chocolate Spreads and Syrups
Popular chocolate spreads and syrups like Nutella and Hershey's fall in the slightly acidic range, around 6.3 to 6.5 pH. The high sugar content can also aggravate reflux.
Other Factors That Impact Acidity
In addition to cacao percentage and ingredients, factors like processing method and additions like flavorings, sweeteners, and lecithin can alter chocolate's acidity slightly. Acidity can vary between brands.
How Acidic Is Chocolate Compared to Other Foods?
To put chocolate's acidity level into context, here's how it compares pH-wise to some other common foods:
- Distilled water - 7.0 pH (neutral)
- Milk - around 6.5 to 6.8 pH (slightly acidic)
- Bananas - 5.5 pH (acidic)
- Oranges - 3.0 to 4.0 pH (very acidic)
- Black coffee - around 5.0 pH (acidic)
- Soda - 2.5 pH (very acidic)
As you can see, chocolate falls somewhere in the middle of the acidity spectrum. It's more acidic than something like milk or bananas, but not as highly acidic as coffee, citrus fruits or sodas.
Does Chocolate Aggravate Acid Reflux?
Chocolate contains ingredients like cocoa, sugar and fat which may relax the lower esophageal sphincter and stimulate acid production in those prone to reflux.
Let's look at how the components in chocolate can impact acid reflux and digestion:
Cocoa and Caffeine
Cocoa, especially in darker chocolates, contains caffeine and biologically active compounds that can stimulate stomach acid secretion. This can loosen the esophageal sphincter and allow acidic stomach contents to back up.
Fat Content
The cocoa butter naturally found in chocolate contains saturated fat that may provoke reflux. Fatty foods can delay stomach emptying and put pressure on the esophageal sphincter.
Sugar
The high sugar content in milk chocolate, syrups and other sweetened chocolate can feed gut yeast and bacteria, promoting fermentation. This creates gas that can trigger reflux.
Irritants
Chocolate has histamine and
FAQs
Does milk chocolate have caffeine?
Yes, milk chocolate contains a small amount of caffeine, typically around 10-15 mg per average size chocolate bar.
Why does milk chocolate have less caffeine than dark chocolate?
Milk chocolate has a lower percentage of cocoa solids compared to dark chocolate. Since the caffeine comes from the cocoa beans, less cocoa means less caffeine.
How much caffeine is in a Hershey's milk chocolate bar?
A 1.55 ounce Hershey's milk chocolate bar contains approximately 9 mg of caffeine. Their Special Dark bar has about twice as much, around 20 mg per serving.
Is the caffeine in chocolate dangerous?
No, the relatively small amounts of caffeine found in chocolate are not harmful for most people. Chocolate has much less caffeine compared to coffee, tea, soda or energy drinks.
Does white chocolate contain caffeine?
No, white chocolate does not contain any caffeine because it does not contain cocoa solids. The cocoa solids are the source of chocolate's caffeine content.
