Final answer:
Consuming more proteins and wheat generally makes the urine pH more acidic due to the production of acids like urea and uric acid during protein metabolism.
Step-by-step explanation:
When we consume more proteins and wheat, the pH of the urine becomes more acidic. Our diet has a significant impact on the acidity or alkalinity of our urine. Consuming foods high in protein, often found in meats and wheat products, can lower urine pH, meaning it becomes more acidic. This is due to the body metabolizing protein to produce acids like urea and uric acid, which lower the pH. Conversely, eating citrus fruits, vegetables, and dairy raises urine pH, making it more alkaline.
It's also worth noting that different times of the day can affect urine pH. For instance, right after eating, an "alkaline tide" can occur, where the urine becomes temporarily more alkaline due to digestive processes. However, typically, a diet high in protein will result in more acidic urine, with a pH less than 7. In contrast, a diet high in fruits and vegetables can result in a more alkaline urine pH, higher than 7. Chronic deviation from the normal pH range may lead to health issues such as kidney stones or osteomalacia.
