Is Apple Cider Vinegar Truly Packed with Probiotics as Claimed?
Apple cider vinegar (ACV) has been a popular household staple for centuries, but its health benefits have been the subject of much debate. This fermented liquid, produced through a two-part fermentation process involving alcoholic fermentation and acetic acid fermentation, contains beneficial organisms such as acetic acid bacteria, polyphenolic compounds, and lactic acid bacteria.
One area where ACV has shown potential benefits is in managing metabolic health. A small 2019 study suggested that ACV consumption might help reduce oxidative stress in people with type 2 diabetes or high cholesterol/triglyceride levels. Another research review from 2021 found that ACV consumption significantly decreased blood sugar and blood lipid levels, particularly in higher doses.
However, it's important to note that the impact of ACV on health, particularly when it comes to probiotics, is not yet fully understood. While ACV does contain lactic acid bacteria, it does not qualify as a true probiotic according to the International Scientific Association for Probiotics and Prebiotics (ISAPP). This is because it does not meet the definition of live microorganisms that benefit health when taken in certain amounts.
On the other hand, foods like yogurt, kefir, and certain fermented dishes such as sauerkraut, kimchi, natto, miso, and tempeh, are known to be rich in probiotics. These beneficial bacteria can support digestive health and boost the immune system. For example, a small 2021 study found that daily ACV consumption for 4 weeks helped boost the moods of healthy college students, but it's unclear if this was due to the probiotic content of ACV.
Kombucha, a fermented tea drink, is another probiotic-rich beverage. Some kombuchas can be good sources of probiotics, but many include added sugar. To reap the most benefits, it's best to opt for low-sugar or unsweetened varieties.
While ACV might offer other health benefits, it's crucial to approach these claims with caution. Most health claims surrounding ACV are exaggerated, and ACV products should not be used to treat, prevent, or cure diseases. Instead, focus on incorporating a variety of probiotic-rich foods into your diet for overall health and well-being.
