Popular questions
Does milk help acid reflux?
Milk can briefly buffer stomach acid, but its fat and protein may stimulate acid production later, so effects vary by person; fermented dairy contains lactic acid (E270), whose acidity helps tartness and may help or bother individuals depending on sensitivity.
How to drain lactic acid from legs?
You don’t need to “drain” it—exercise-produced lactate (the same molecule as food additive E270 in ion form) is naturally cleared or reused for energy within about an hour. Muscle soreness after workouts is from microdamage, not trapped lactic acid; light movement and time help.
What does lactic acid do?
In foods, E270 is an acidity regulator and flavoring that lowers pH to add a tangy taste and stabilize products. It also inhibits spoilage microbes and is used to reduce pathogens on meats and in fermented foods, beverages, and pickles.
What does lactic acid do for skin?
As an alpha‑hydroxy acid, lactic acid gently exfoliates and increases skin hydration, helping smooth texture and brighten dullness. At higher strengths or low pH it can irritate sensitive skin.
How to get rid of lactic acid?
Your body naturally clears exercise-produced lactate quickly, so there’s no need to “flush” it. Staying hydrated and doing light activity can support normal clearance; lactic acid in foods (E270) doesn’t cause muscle lactate buildup.
Is phosphoric acid bad for you?
At permitted food levels it’s considered safe (GRAS in the U.S.; EFSA sets a group ADI for phosphates of 40 mg/kg bw/day as phosphorus). Overconsumption—especially via acidic soft drinks—can contribute to dental enamel erosion, and high phosphate intakes may be a concern for people with kidney disease.
Is phosphoric acid a strong acid?
No—it's a weak, triprotic acid (pKa ≈ 2.15, 7.2, 12.3), though concentrated solutions are corrosive.
What is phosphoric acid used for?
In foods it’s used as an acidulant to add tartness and control pH (e.g., in colas) and as a sequestrant/antioxidant to stabilize color and flavor.
What does phosphoric acid do to the body?
It dissociates into phosphate ions, which are essential for bones and energy metabolism, while the acid load is buffered and excreted. High intakes from acidic drinks can erode tooth enamel, and excess phosphate may be problematic in kidney disease or with low calcium intake.
What is the formula for phosphoric acid?
H3PO4.
