The alkaline diet, also known as the acid-alkaline or alkaline ash diet, is based on the theory that eating certain foods can alter the pH of your body. The diet includes fresh, nutrient-dense, plant-based foods that are good for you, such as vegetables, fruits, nuts, and legumes. Natural fats, milk, and sugars are considered neutral foods that should be avoided or limited. The alkaline diet may be easier for vegetarians and vegans to follow, as it excludes animal proteins, eggs, and dairy. While the diet may support health by limiting processed foods and promoting whole foods, it does not affect your body's pH levels and fight disease as claimed. There is also no evidence that high levels of 'excess' acid in the body contribute to health conditions such as arthritis, osteoporosis, and cancer. The long-term effects of the alkaline diet depend on the version adopted, with a strict eating plan that eliminates grains, dairy, and animal foods potentially leading to deficiencies in protein, vitamins, and minerals. The restrictiveness of the diet may also make it challenging to maintain for an extended period.

The alkaline diet is based on the theory that eating certain foods can alter your body's pH levels
However, the claim that the alkaline diet can change your body's pH level is unproven. While food can change the pH value of urine, it does not significantly affect blood pH levels, which are tightly regulated by the body. Urine pH is a poor indicator of overall body pH and general health. The health benefits of the alkaline diet are attributed to its emphasis on whole and unprocessed foods, not to any alteration of the body's pH levels.
The alkaline diet generally includes fruits, vegetables, nuts, legumes, and whole foods, while discouraging processed foods, added sugars, alcohol, caffeine, and animal protein. It gained popularity through celebrity endorsements and has been promoted as a way to lose weight and prevent diseases like arthritis and cancer.
While the alkaline diet may offer health benefits due to its focus on nutritious and unprocessed foods, it is important to note that it is restrictive and may be challenging to maintain in the long term. It is always recommended to consult a doctor or healthcare professional before starting any new diet or nutritional plan.
There is limited research on the long-term effects of the alkaline diet, and it is important to consider individual differences in responses to different diets. While it may provide some health benefits, it is not a cure-all, and a balanced diet that includes a variety of food groups is generally recommended for optimal health.

The diet promotes whole foods and limits processed foods, natural fats, milk, and sugars
The Alkaline Diet, also known as the acid-alkaline or alkaline ash diet, is based on the idea that eating certain foods can alter the pH of your body. The diet categorises foods as acidic, alkaline, or neutral. Acidic foods include meat, poultry, fish, dairy, eggs, grains, and alcohol. Neutral foods include natural fats, milk, starches, and sugars. Alkaline foods include fruits, nuts, legumes, and vegetables.
The alkaline diet promotes the consumption of whole foods and limits processed foods. Natural fats, milk, and sugars are considered neutral foods, and advocates of the diet recommend limiting or avoiding them. The diet also excludes wheat and other major food allergens, including eggs, peanuts, walnuts, fish, and shellfish. It is vegetarian and can be vegan, as dairy is off-limits.
The alkaline diet is popular among Hollywood celebrities, and its recommended foods are largely in line with healthy eating guidelines. However, the diet lacks scientific evidence and may be difficult to maintain in the long term due to its restrictiveness. While it may lead to temporary weight loss, this is likely due to the elimination of many food groups and may not be sustainable.
The alkaline diet is based on the theory that metabolic waste or "ash" left from food combustion affects the body's acidity or alkalinity. It claims that the body takes alkaline minerals from bones to maintain a constant blood pH, potentially leading to osteoporosis. However, studies suggest that diet does not significantly affect blood pH and that the alkaline diet is not beneficial for bone health.
In conclusion, the alkaline diet promotes whole foods and limits processed foods, natural fats, milk, and sugars by categorising them as neutral foods to be limited or avoided. While the diet may lead to temporary weight loss, it lacks scientific evidence and may be challenging to maintain due to its restrictive nature.

There is no conclusive evidence that the diet works, and it may be deficient in protein and other vital nutrients
The alkaline diet, also known as the acid-alkaline or alkaline ash diet, is based on the idea that eating certain foods can alter the pH of your body. It involves eating fresh, nutrient-dense foods and limiting processed foods, natural fats, milk, sugars, and other junk foods. While the diet may sound appealing, there is currently no conclusive evidence that it works as intended.
Firstly, the diet's effectiveness hinges on the claim that it can alter the pH of your body, specifically your blood. However, studies have shown that diet does not significantly affect blood pH in healthy individuals. While the diet may indeed change the pH of your urine, saliva, or sweat, this does not reflect a change in blood pH, which is tightly controlled and remains largely unaffected by food.
Secondly, the alkaline diet is often promoted as a way to improve bone health and prevent diseases like osteoporosis. However, research has found no evidence to support this claim. In fact, a high-protein, acid-forming diet may be linked to better bone health due to increased calcium retention and activation of the IGF-1 hormone.
Additionally, the alkaline diet may be deficient in certain vital nutrients. It eliminates important nutrient-rich foods like animal proteins, eggs, and fish, which can be critical for growth and development, especially in children. The diet may also cut out specific fruits, vegetables, and almost all grain foods, potentially leading to a lack of essential vitamins, minerals, and fibre.
While the alkaline diet may have some benefits due to its focus on whole, unprocessed foods, it is important to recognise that many of its supposed benefits are not backed by scientific evidence. It is always recommended to consult with a healthcare professional before starting any new diet, especially restrictive diets like the alkaline diet, which may be challenging to maintain in the long term.

The alkaline diet is mostly vegetarian/vegan and gluten-free
The alkaline diet is based on the idea that consuming alkaline foods and avoiding acidic foods can make your body more alkaline and protect against health conditions. However, it's important to note that the claim that the diet changes the body's pH levels is unproven. While the alkaline diet restricts many foods, including meat, dairy, alcohol, caffeine, and processed foods, it aligns with vegetarian, vegan, and gluten-free diets in particular.
Vegetarian and Vegan Aspects
The alkaline diet is mostly vegetarian because it restricts meat and animal protein. It can also be vegan because it excludes dairy. The diet focuses on plant-based, nutrient-rich whole foods, including vegetables, fruits, legumes, nuts, and seeds. For example, beets, broccoli, cabbage, avocados, bananas, spinach, kale, berries, quinoa, lentils, almonds, cucumbers, mushrooms, and chia seeds are all considered alkaline foods.
Gluten-Free Aspects
The alkaline diet is also gluten-free as it excludes wheat. However, to completely avoid gluten, one must carefully check food labels because gluten is found in various foods beyond just wheat.
Sample Vegan Meal Ideas
The alkaline diet can be tailored to suit individual tastes and preferences. Here are some meal ideas to get you started:
- Peach and blueberry baked oats for breakfast
- Garden veggie burger with a variety of vegetables, served on a bed of leafy greens and grains
- Whole roasted celeriac as a centerpiece, paired with other alkalizing veggies and grains

The long-term effects of the diet will vary depending on the version adopted
The alkaline diet, also known as the acid-alkaline or alkaline ash diet, is based on the theory that eating certain foods can alter the pH of your body. The diet claims that high levels of 'excess' acid in the body, caused by modern diets, contribute to various health conditions, including arthritis, osteoporosis, kidney and liver disorders, and even cancer. While the alkaline diet has been suggested to prevent a number of diseases and promote significant health benefits, many of its so-called benefits are not backed by scientific evidence.
On the other hand, a balanced version of the diet that includes some grains and animal protein along with plant-based foods may have more positive long-term effects. The alkaline diet can be easier for vegetarians and vegans to follow, as it is mostly vegetarian and excludes dairy. For those with gluten intolerance, the diet excludes wheat, but it is important to carefully check food labels to avoid gluten entirely.
While the alkaline diet may not significantly affect blood pH, it can change urine pH. Advocates of the diet often test their urine pH to determine if the diet is "working." However, it is important to remember that urine pH does not reflect a change in blood pH levels or the current state of one's health.
Overall, the restrictiveness of the alkaline diet may make it challenging to maintain for the long term. It is always recommended to consult with a doctor before starting any new eating plan, as everyone responds differently to different diets.
