Are Cherries Acidic or Alkaline? Understanding the pH Scale and Cherry's Impact on Your Body
The question of whether cherries are acidic or alkaline often sparks confusion. The answer isn't as simple as a straightforward "acidic" or "alkaline," as it depends on how you're measuring acidity and what effect they have on your body. Let's delve into the details.
Understanding pH: The pH scale measures how acidic or alkaline a substance is, ranging from 0 to 14. A pH of 7 is neutral. Anything below 7 is acidic, and anything above 7 is alkaline.
Cherries' pH: Cherries themselves have a relatively acidic pH, generally falling between 3.3 and 4.5. This is because they contain various organic acids like malic acid, citric acid, and tartaric acid. These contribute to their characteristic tartness.
So, why the confusion about cherries being alkaline-forming?
This is where things get interesting. While cherries are acidic before digestion, their effect on the body's pH after metabolism is different. This is often referred to as "potential renal acid load" (PRAL).
The PRAL value assesses the overall acid-base balance in the body after consuming a food. The calculation takes into account not only the initial pH but also the metabolism of the food's components. While cherries have a low pH, their PRAL value is often considered to be relatively low, meaning they are less likely to significantly increase the acidity in your body. In other words, they are considered to be alkaline-forming foods in the context of their metabolic effect.
What is the potential renal acid load (PRAL) value of cherries?
Unfortunately, there's no single definitive PRAL value universally agreed upon for cherries. The exact value can vary depending on factors like the cherry variety, ripeness, and growing conditions. However, generally, cherries are considered to have a low to moderate PRAL, placing them closer to the alkaline-forming end of the spectrum concerning their net effect on the body's acid-base balance.
Do cherries affect blood pH?
Your body has robust mechanisms to regulate blood pH, keeping it within a very narrow range (slightly alkaline). Consuming cherries, whether acidic or alkaline-forming, is unlikely to significantly alter your blood pH because of these regulatory systems. Severe imbalances in blood pH are a serious medical condition requiring immediate attention.
What about people with acid reflux or other digestive issues?
While cherries are generally considered safe, individuals with sensitive stomachs or acid reflux might experience discomfort due to their inherent acidity. Moderation is key, and if you experience any problems after consuming cherries, it's advisable to reduce your intake or consult with a doctor or registered dietitian.
Can cherries help with alkalinity in the body?
While cherries contribute to a relatively lower PRAL value, they shouldn't be considered a primary means of alkalizing your body. A balanced diet rich in various fruits, vegetables, and other alkaline-forming foods is essential for maintaining optimal acid-base balance.
In conclusion, while cherries are acidic in their raw form, their metabolic effect on the body's pH after digestion suggests they have a relatively low acid load. Their impact on overall body pH is minimal due to the body's natural regulatory processes. However, individual sensitivities may vary, so moderation is recommended. If you have concerns about your dietary acid-base balance, it is always best to consult a healthcare professional.
