The alkaline diet sometimes referred to as the alkaline ash diet or alkaline acid diet, can aid in weight loss and protect against conditions like cancer and arthritis. According to the notion, eating things like meat, wheat, refined sugar, and processed meals might make your body produce unhealthy amounts of acid. The foundation of the alkaline diet is the notion that consuming more alkaline foods instead of acid-forming ones will benefit your health. Even yet, this diet’s proponents assert that it can aid in the battle against life-threatening illnesses like cancer.
How effective are alkaline diets? According to research, a more alkaline urine pH level is produced by diets heavy in very alkaline foods, such as fresh produce, fruits, and unprocessed plant-based sources of protein. This helps to protect healthy cells and balance critical mineral levels. Given that hormone levels might be affected, this may be particularly crucial for women who practice intermittent fasting or follow the ketogenic diet.

What is Alkaline Diet

The foundation of the alkaline diet is that the things you eat alter your pH level, making it either acidic or alkaline. The idea is that eating a lot of acidic meals will injure your body, whereas eating a lot of alkaline or neutral foods will make you healthier.

The diet emphasizes consuming alkaline foods such as fresh fruits and vegetables to maintain a healthy pH level in the body, which is a measurement of the presence of acids and alkalis in a range from 0 to 14.

Alkaline foods vary from 7 to 14, while acidic things range from 0 to 7. The number seven is regarded as neutral, not acidic nor alkaline.

The “dietary ash hypothesis,” a belief that once the food is digested in the body, the particles leave either an acidic or alkaline ash, gave rise to this idea centuries ago, in the middle of the 1800s.

The alkaline diet is ranked number 30 in Best Diets in U.S. News and World Report 2022. Overall, he assigns a rating of 2.4/5 to the diet. Its ranking is determined by the diet’s ineffectiveness for weight reduction, the numerous regulations that make it challenging to follow, and the paucity of high-quality research supporting the diet. The Alkaline Diet did poorly regarding quick weight reduction, overall weight loss, managing diabetes, and ease of implementation.

How an Alkaline Diet Works

Foods are categorized in the alkaline or acid-ash diet based on how much acid they produce after digestion. The amount doesn’t always correspond to 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 there is a wealth of data demonstrating that altering the pH of the body 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 in order to function. The pH of your body cannot be altered by dietary habits. The pH of your urine, which can be checked with a straightforward dipstick test (also known as a pee test strip), may change, but it won’t tell you how you’re doing overall because urine pH doesn’t correspond to your body’s pH. The American Institute for Cancer Research explains that this is because too much acid may be eliminated through the urine in an attempt to balance the pH levels of the body (AICR).

What Are the Potential Health Benefits of an Alkaline Diet?

This particular diet type, which is high in fresh produce, does not necessitate extensive meal preparation or the capacity to prepare complicated recipes. Simply eat plenty of fruits and vegetables, along with some grains and unrefined oils. However, there is little evidence to back up claims that the alkaline diet can aid in weight loss and illness prevention. However, some evidence indicates that certain dietary components might have health advantages.

  • Maintains Muscle Mass: As you age, maintaining your muscle mass may be possible if you follow an alkaline diet. Researchers found that high consumption of potassium-rich foods, such as fruits and vegetables in an alkaline diet, may assist older persons to maintain muscle strength as they age in a three-year clinical trial involving 384 men and women 65 and older.
  • Lowers Risk for Hypertension and Stroke: Reducing Inflammation and Increasing Growth Hormone Production are Two Anti-Aging Effects of an Alkaline Diet. It has been demonstrated that doing so enhances cardiovascular health and provides defence against widespread issues including excessive cholesterol, hypertension (high blood pressure), kidney stones, stroke, and even memory loss.
  • Might Aid in Diabetes Prevention: Avoiding meals with acids may assist you to avoid developing diabetes. In a study that was published in Diabetologia, scientists tracked 66,485 women over the course of 14 years. Medical personnel identified 1,372 new cases of diabetes during that time. The women with the most acid-forming diets had a noticeably increased chance of acquiring diabetes, according to an examination of their dietary habits.
  • Increases Magnesium Absorption and Prevents Magnesium Deficiency: Magnesium is essential for the proper operation of thousands of enzyme systems and biological functions. Many people have magnesium deficiencies, which lead to heart problems, muscle pain, migraines, sleep issues, and anxiety.
    Additionally necessary for the activation of vitamin D and preventing vitamin D shortage, which is crucial for proper immunological and endocrine function, is readily available magnesium.
  • Can Assist You Maintain a Healthy Weight: Although the diet isn’t just about losing fat, an alkaline diet meal plan can unquestionably help guard against obesity. Due to the diet’s capacity to lower leptin levels and inflammation, limiting consumption of acid-forming meals and increasing consumption of alkaline-forming foods may make it simpler to lose weight.

What You Can Include In Your Alkaline Diet

Eating foods that rank highly on the pH list and fall within the permitted ranges for protein, fat, and carbohydrates is the fundamental tenet of the alkaline diet. You only need to eat items that tilt your pH balance into alkaline levels. You don’t need to stick to any particular diet or eat at particular times.


Although not all fruits are permitted, you may consume the following:

  1. Apples
  2. Apricots
  3. Dark berries
  4. Citrus juice
  5. Oranges
  6. Peaches
  7. Pears


Although not all veggies are permitted, you may eat:

  1. Asparagus
  2. Broccoli
  3. Carrots
  4. Celery
  5. Cucumber
  6. the beans


You can drink alcohol and coffee in moderation on this diet:

  1. Coffee, which is slightly acid
  2. Red and white wine

What Food Should You Avoid?

  1. Processed food is laden with sodium chloride, or table salt, which tightens blood vessels and makes food acidic.
  2. Standard meats and cold cuts
  3. Refined cereals (such as corn flakes)
  4. Eggs
  5. Alcoholic beverages
  6. Whole wheat and oat products: All grains, whether whole or not, cause the body to become acidic. The majority of the plant food that Americans consume is processed corn or wheat.
  7. Dairy products high in calcium are one of the main contributors to osteoporosis. That is as a result of the acidity they give to the body! It will try to adjust the pH level by stealing calcium (a more alkaline material) from the bones when your bloodstream becomes too acidic. So eating a lot of alkaline green vegetables is the greatest method to avoid osteoporosis!

Downsides Of An Alkaline Diet

The idea behind the alkaline diet is that by consuming specific foods that alter the pH of the body, you may enhance your health. The benefits of eating a diet low in acidic foods, however, are not supported by scientific research. 6 Here are several drawbacks to an alkaline diet.

  • Lack of Dairy Products: When following a dairy-free diet, it can be challenging to replace the vital elements found in dairy products, such as calcium, magnesium, phosphorus, and potassium. Additionally, obtaining adequate calcium solely from veggies is challenging. Because spinach has a high concentration of calcium-binding oxalates and phytates, despite the fact that it contains a lot of calcium, very little of it is really absorbed.
  • Lack of Protein: Because there aren’t many high-quality, bioavailable protein sources allowed in the alkaline diet, getting enough protein might be challenging. Adults should consume between 10% and 35% of their daily calories from protein, according to current recommendations. Although fruits and vegetables may have some protein, it might be difficult to eat enough of them to obtain the daily necessary quantity. Lack of protein may be a factor in a variety of problems, including diminished muscle mass and malnutrition.


The alkaline diet is a healthy alternative that might be effective since it places more of emphasis on eating plants and avoiding processed foods than it does on altering the pH of the body.

Your body’s pH levels may or may not be balanced by eating more fruits and vegetables, fewer processed carbohydrates, sugar, and dairy products, and increasing your intake of these foods.

In either case, a diet high in plants and low in refined sugar has many health advantages, may lessen day-to-day problems and may minimise the likelihood of some long-term health hazards.
