What are apple polyphenols?
Polyphenols are a large, diverse group of phytochemicals (plant chemicals) found in many fruits, vegetables, nuts, seeds, flowers and other plants. There are over 8,000 identified polyphenols in nature. Apples are one of the best sources, containing a wide variety of polyphenol compounds.
The main classes of apple polyphenols include:
Flavonoids like quercetin, catechin, phloridzin and rutin. Flavonoids give apples their vibrant color.
Phenolic acids like chlorogenic acid and caffeic acid. Phenolic acids have antioxidant effects.
Dihydrochalcones like phloretin. These influence flavor.
Stilbenes like resveratrol. Stilbenes occur in small amounts in apples.
The polyphenol content of apples depends on the variety. Red delicious, granny smith, gala, and pink lady apples have some of the highest polyphenol levels. The skin of the apple contains much higher polyphenol concentrations than the flesh.
Polyphenols act as antioxidants that stabilize free radicals and reduce oxidative damage. They also have anti-inflammatory effects in the body. Eating polyphenol-rich foods like apples is associated with health benefits like improved heart health, better blood sugar control, and reduced risk of neurodegenerative diseases.
Does vinegar have polyphenols?
Yes, vinegar can contain polyphenols. Polyphenols are found in the fruits, vegetables, herbs and other plant materials used to produce vinegar. Many types of vinegar, including apple cider vinegar, retain polyphenols from their plant sources throughout the vinegar production process.
Vinegar is made by fermenting sugars into acetic acid. This fermentation process often preserves some of the polyphenol compounds present in the original plant source:
Apple cider vinegar contains apple polyphenols like chlorogenic acid, phloridzin, quercetin and catechin.
Red wine vinegar contains resveratrol and quercetin from grapes.
Balsamic vinegar made from grapes includes flavonoids like catechin and quercetin.
Rice wine vinegar contains ferulic acid and other polyphenols from rice.
The polyphenol content depends on the plant material, fermentation methods, and processing techniques. Unfiltered, unpasteurized vinegars have higher levels than clarified and distilled vinegars.
Vinegar polyphenols act as antioxidants. They also provide anti-inflammatory, anti-diabetic, antimicrobial, and anticancer effects. So vinegar can offer various health benefits associated with its polyphenol compounds.
Is apple cider vinegar an antioxidant?
Yes, apple cider vinegar is an antioxidant drink due to its acetic acid content and antioxidant polyphenols. These components give apple cider vinegar free radical scavenging abilities and antioxidant properties.
Acetic acid, the main active component of apple cider vinegar, acts as an antioxidant. It reduces oxidative stress by inhibiting the production of free radicals and reactive oxygen species. Acetic acid also increases glutathione, the body's master antioxidant.
In addition to acetic acid, apple cider vinegar contains antioxidant polyphenols like chlorogenic acid, catechin, epicatechin, phloridzin and quercetin. These apple polyphenols are extracted from apples during the crushing and fermentation process.
Research shows the antioxidant capacity of apple cider vinegar equals or exceeds that of other vinegar types. In lab tests, apple cider vinegar decreases free radical formation, neutralizes existing free radicals, and protects cells from oxidative damage.
The antioxidant effects of apple cider vinegar's acetic acid and polyphenols provide health advantages:
Reduces inflammation
Improves cardiovascular health
Enhances skin health
Protects brain cells
