We all have heard about acid, the component that exists in our daily beverage, from fruit and vegetables to meat and snacks, from food to cosmetics. But have we ever questioned its effectiveness and possible side effects? To begin with, we need to learn a bit more about the pH scale. It defines the state of a substance, which can be categorized into three levels: acidic, neutral, or alkaline.

Benefits of Acids to Health

Acids are not always harmful; in fact, many play essential roles in maintaining our well-being:

1. Digestion and Metabolism
   One of the most important acids in the human body is hydrochloric acid (HCl), found in the stomach. It helps break down food, activate enzymes, and kill harmful bacteria. Without it, proper digestion would be nearly impossible.
2. Nutrient Absorption
   Certain vitamins and minerals, such as vitamin B12 and iron, require an acidic environment for absorption. A lack of stomach acid can lead to nutrient deficiencies and fatigue.
3. Preservation and Safety
   Mild acids in food, such as citric acid in citrus fruits and acetic acid in vinegar, help preserve food and prevent the growth of harmful microorganisms.
4. Skin and Hair Care
   Many cosmetic products contain mild acids like lactic acid or salicylic acid, which help exfoliate dead skin cells, improve skin texture, and fight acne.

Drawbacks and Risks of Excessive Acidity

However, too much acid—whether in the body or in products we consume—can be harmful:

1. Tooth Enamel Erosion
   Acidic drinks like soda, citrus juices, and energy drinks can erode tooth enamel over time, leading to sensitivity and cavities.
2. Acid Reflux and Heartburn
   Excess stomach acid or frequent consumption of acidic foods can trigger acid reflux, a condition where stomach acid flows back into the esophagus, causing discomfort and potential damage.
3. Skin Irritation
   Overuse of acidic skincare products can damage the skin’s natural barrier, leading to dryness, redness, or even chemical burns in severe cases.
4. Body pH Imbalance
   While the body regulates its internal pH tightly, excessive intake of highly acidic foods, combined with other factors, may stress the body’s buffering systems, potentially contributing to fatigue or bone health issues over time.

Finding the Balance

Acids are not the enemy; they are essential for life when present in the right amounts. The key lies in moderation and understanding the purpose of each type of acid—whether it is in our diet, our skincare routine, or our environment. By maintaining this balance, we can enjoy the benefits of acids without falling victim to their negative effects. We should pay attention to the acidity of products using in daily consumption, and maybe look for low acid options as well.
