Tips for Limiting Acidic Food

The body tightly controls its pH equilibrium through several systems that include several organs, including the kidneys and lungs. Research typically indicates that eating acidic or alkaline meals is unlikely to significantly affect the pH level of your blood, even though your diet may change the pH of your urine.

In fact, elevated levels of acid in the blood are typically a sign of an underlying medical condition, such as poorly controlled diabetes, lung illness, or renal issues. Some people may decide to limit acid-rich foods to lessen their potential renal acid load (PRAL), the amount of acid your body creates due to the meals you eat. The amount of acid produced during digestion increases with increasing PRAL ratings.

Recently, the alkaline diet has gained popularity, with everyone from celebrities to health experts praising the advantages of eliminating acidic items from your diet. According to studies, restricting your intake of acidic foods as part of an acid reflux diet may enhance bone density, lessen your risk of kidney stones, reduce chronic pain, improve hormone levels, and relieve acid reflux. Reducing your consumption of some of the most acidic meals can be beneficial while maintaining a balanced diet rich in nutrient-dense, unprocessed foods.

What is Acidity?

The pH scale indicates whether a substance is acidic, basic, or neutral.

  • High acidity is indicated by a pH of 0.
  • Seven is the neutral pH.
  • The most elevated basic, or alkaline, pH value is 14.

The difference in acidity or alkalinity between any two points on the pH scale corresponds to a tenfold difference. The acidity doubles from a pH of 6 to a pH of 7, and so forth. For instance, the liquid drain cleaner is alkaline at 14, whereas battery acid is very acidic at 0. The middle number, 7, is pure distilled water. It is neither alkaline nor acidic. The pH levels of various body areas vary, just like with different substances. The optimal blood pH range is slightly alkaline, between 7.35 and 7.45. The stomach typically has an acidic pH of 3.5, which aids in appropriate food digestion.

Foods And Drinks That Are High In Acid

The pH of food regarded as acidic is typically 4.6 or lower. You may wish to limit or stay away from some foods since they tend to increase body acidity:

  • some dairy products, such as cheese
  • seafood and fish
  • prepared meals high in sodium
  • fresh meats and processed meats, such as turkey and corned beef
  • a few starchy meals, such as granola, brown rice, or oat flakes
  • fizzy drinks like spritzers, soda, and seltzer
  • Foods and supplements high in protein that contain animal protein

The idea that meals like animal protein induce chronic disease by changing the body's pH needs to be better supported by the available research. Research may clarify this relationship more or uncover further arguments in favour of cutting back on animal products for health reasons.

Fruits High In Acid

Although most fruits are acidic, they are considered alkalizing, which means they actively work to lower the body's acid levels. They also have a negative PRAL, a measurement used to gauge how much acid is created during the digestion of particular foods.

The PRAL is for a 3.5-ounce (100-gram) serving of many well-known fruits. For instance, pomegranates contain -8.1, blueberries contain -0.6, pineapples contain -1.1, apples contain -1.1, aches contain -1.5, oranges contain -1.6, tomatoes contain -1.8, raisins contain -9.0, blackberry contains -1.0, banana contains -5.2, limes contains -0.4, plums contains -1.7, green grapes contains -2.4, and purple grapes contains -1.9

But all the fruits are alkalizing in the body; remember that their early acidity may exacerbate symptoms in people with upper gastrointestinal problems such as an ulcer or reflux.

Fresh Vegetables

Like fruits, veggies are thought to be alkalizing and can help lower acid levels in the body.

The PRAL for 3.5 ounces (100 grams) of several common vegetables, such as White cabbage, beets, shiitake mushrooms, kale, zucchini, spinach, cucumber, cooked potatoes, raw radish, artichoke, pumpkin, and arugula is as follows: White cabbage: -1.5, beets: -5.4, shiitake mushrooms: -0.2, kale: -2.6, zucchini: -0.6, spinach: -1.5.

Effects Of Consuming Too Many Foods That Produce Acid

Like fruits, veggies are thought to be alkalizing and can help lower acid levels in the body. Too many acid-producing foods in your diet, such as animal proteins, some cheeses, and carbonated beverages, can contribute to urine acidity and other health problems. This could result in the formation of kidney stones of the uric acid kind.

Excessive acidity may lead to the degradation of bones and muscles. This is due to the calcium found in bones, which your body utilizes to regulate blood pH when it becomes too acidic. However, due to the variances in total diet across test individuals, research has produced contradictory conclusions on how acidic foods may impair bone and muscle health (9Trusted Source). Additionally, eating moderate amounts of foods high in acid as part of a nutritious, balanced diet that includes lots of fruits and vegetables is unlikely to raise the risk of chronic disease or result in muscle or bone loss.

According to some research, drinking dark sodas instead of milk, a beverage high in calcium and protein, is associated with poorer bone density. Phosphoric acid is a prominent ingredient in these drinks. Additionally, cancer, liver issues, and heart disease risk factors may all be exacerbated by excessive acidity.

Some foods and drinks don't produce as much acid as protein or sodas, but they don't have the same significant alkalizing effects. The exact dietary lists are only sometimes agreed upon by experts.

Limit these meals as much as you can because they could be harming your health or your acid-base balance:

  • salt
  • Soy sauce, steak sauce, barbecue sauce, and several salad dressings are high-sodium condiments.
  • certain varieties of cheese, such as brie, mozzarella, and parmesan
  • grains like wheat, rice, and maize

To balance your dietary acid load and promote general health, consume a well-balanced diet full of fruits, vegetables, whole grains, and healthy fats. Occasionally replacing animal proteins in your diet with plant-based proteins like beans, lentils, tofu, and tempeh can also be beneficial.

Calcium, vitamin D, phosphorus, magnesium, and other essential elements for bone health can be found in nutrient-dense foods like cow's milk.

The alkaline diet's central tenet is that our blood's pH balance is influenced by what we eat. You might remember from chemistry class that something's pH indicates how acidic or alkaline it is. It falls between 0 and 14.

  • 0 is quite acidic.
  • 14 is quite alkaline 
  •  7 is neutral.

Diets high in some items, like meat and grains, and low in others, like potassium-rich vegetables and fruits, can induce pH imbalances in the blood, which can result in several health issues, according to proponents of the alkaline diet. The alkaline diet is occasionally referred to as the "acid-ash diet" because of the acid-ash hypothesis.

Taking Alkaline Diet

Foods are categorized into the alkaline or acid-ash diet based on how much acid they produce after digestion. The amount sometimes varies from the degree of acidity in raw food. According to studies, alkaline foods result in a pH level greater than 7, while acid-forming foods produce a pH level lower than 7. Any food with a pH value of around 7 is regarded as neutral. In light of this, the diet suggests:

  • avoiding items that cause acidification, including meat, dairy, fish, eggs, wheat, and alcohol
  • eating a lot of foods that produce alkalines, such as fruits, vegetables, nuts, and legumes
  • reducing the consumption of neutral foods, including grains, sugars, and natural fats

Again, there is little evidence to suggest that the pH of food has any bearing on general health, yet a wealth of data demonstrates that altering the body's pH by diet is just not conceivable. In truth, different parts of the body have different pH levels. For instance, the stomach must be highly acidic to function.

The kidneys and lungs carefully control the varying pH levels, primarily in charge of doing so. According to Jennifer Fitzgibbon, RDN, a licensed oncology dietitian at Stony Brook University Cancer Centre in New York, blood pH ranges from 7.2 to 7.45. According to UC San Diego Health, the kidneys also aid in maintaining a neutral pH level in the urine. Michigan Medicine says a urine pH of 4 is considered very acidic, whereas pH ranges from 7 (neutral) to 9 (severely alkaline).

Limiting Alcohol Consumption

Alcohol is very acidic and contains a lot of sugar. It can be lethal in big doses. It is absolutely "ok" if you occasionally enjoy a glass of beer or wine. Just be mindful of how much alcohol you consume.

Drink Alkaline Water

At least 8 to 10 glasses of alkaline water should be consumed daily. While alkaline water has roughly 9 Ph, typical tap water has an alkaline concentration of 6.5 to 7. This will ensure that your body is well-hydrated and that no extra gas or acid is produced.


Frequently perspire a lot. Additionally, controlling acidity will aid in weight loss.

Seek Balance

Since stress significantly contributes to acidity, you should choose mind-altering activities like yoga, meditation, deep breathing, and long walks.


Researchers advised consuming a 3-to-1 ratio of foods that produce alkaline, such as fruits and vegetables. The amount of acid or alkaline created by the digestion and metabolism of food is more significant than its pH before consumption.

There is a slight chance that the urine's pH will be overly alkaline. However, an issue that is more prevalent in the United States is too much acid. This is because the typical diet contains too few fruits and vegetables and too much animal protein and grains. Increased prescription drug usage rates are another factor in the issue.

Following an alkaline diet is unlikely to significantly affect blood pH levels for most healthy adults since the body tightly manages its pH balance through various intricate systems. To maintain a proper acid/base balance and general health, a balanced diet that includes more fruits, vegetables, dairy products like milk and yogurt, more plant protein sources, and fewer processed foods may be helpful. Increasing your intake of fruits and vegetables and decreasing your intake of processed foods heavy in sodium will assist your body's pH levels to stay balanced. It has been demonstrated that adopting a more plant-based diet can lower your chance of developing chronic diseases.
