The alkaline diet, also known as the alkaline-acid diet or acid-ash diet, is based on the theory that eating certain foods can change your body's pH level, making it more alkaline. This is said to help ward off chronic diseases, promote weight loss, and improve overall health. The diet generally includes nutrient-dense, unprocessed, and plant-based foods like fruits, vegetables, legumes, and nuts, while reducing processed foods, meats, dairy, eggs, grains, alcohol, and caffeine. While some people claim positive results, there is limited research supporting the diet's effectiveness in changing the body's pH, and it may come with health risks, especially for certain groups. It is always recommended to consult a healthcare professional before starting any restrictive diet.

What You'll Learn
Eat more fruits and vegetables
The alkaline diet is based on the idea that eating certain foods can alter the pH of your body. It claims that eating foods of a certain pH level can help ward off chronic diseases and benefit health. However, there is little research to support these claims. In fact, it is known that food does not usually cause a major change in the pH of your blood.
Despite this, the alkaline diet recommends eating more fruits and vegetables, drinking lots of water, and cutting back on sugar, alcohol, meat, and processed foods. This can be a good way to improve your overall health, aid in weight loss, and even help lower your cancer risk—just not by alkalizing the body.
Fruits and vegetables are alkaline-promoting foods, so they are a big part of the alkaline diet. Most fruits and vegetables are alkaline, but some are more so than others. For example, dark, leafy greens like spinach, kale, and broccoli are rich in alkaline minerals. Other alkaline fruits and vegetables include:
- Cucumbers
- Celery
- Cabbage
- Squash
- Lemons
- Limes
- Avocados
- Onions
- Garlic
It is important to note that the alkaline diet can be restrictive and may not be suitable for everyone. It is always recommended that you talk to a doctor or dietitian before beginning a new diet.

Reduce intake of processed foods
The alkaline diet is based on the idea that eating certain foods can change your body's pH level, making it more alkaline. Proponents of the diet believe that this can help ward off chronic diseases and improve health. However, it is important to note that there is little scientific evidence to support these claims. In fact, it is known that diet does not significantly affect blood pH levels, which are tightly regulated by the body.
The alkaline diet recommends reducing the intake of processed foods and meats in favour of plant-based, nutrient-dense whole foods. Processed foods are considered acidic and are not allowed on the alkaline diet. This includes canned and packaged snacks, convenience foods, and other highly processed items. By reducing or eliminating these foods, the diet aims to lower the consumption of acidic substances and promote a more alkaline environment in the body.
It is worth noting that the alkaline diet can be restrictive, and it is always recommended to consult a healthcare professional before starting any new diet, especially one that involves cutting out entire food groups. While reducing processed foods may have some benefits, it is important to ensure that you are not unintentionally harming your health or missing out on important nutrients.
Some people may find it challenging to reduce their intake of processed foods due to factors such as cost, convenience, and taste preferences. It may require more trips to the grocery store and more time spent preparing meals using fresh, unprocessed ingredients. However, reducing processed foods can be beneficial as these foods tend to be high in added sugars, unhealthy fats, and salt, while often lacking in essential nutrients.
Overall, while the alkaline diet's premise of reducing processed foods may be reasonable, it is important to approach it with caution and ensure that it is done in a safe and sustainable manner.

Cut down on meat and animal proteins
The alkaline diet is based on the unproven notion that health benefits can be gained by moving the body's chemistry to the alkaline side of the pH scale. The diet claims that eating foods of a certain pH level can help ward off chronic diseases and benefit health, but there is little research to support these claims.
The diet involves reducing the consumption of processed foods and meats in favour of plant-based foods. It is almost entirely vegetarian, with most forms of meat and dairy being off-limits. However, some people choose to include meat in their alkaline diet, but they ensure that it is of the highest quality and most ethical purchase possible. This includes options that are organic, pasture-raised, grass-fed, free-range, and hormone-free.
Cutting down on meat and animal proteins can be challenging, as these foods are significant sources of protein. However, there are plenty of non-animal, vegan proteins available. These include quinoa, oats, beans, pulses (such as chickpeas, lentils, and kidney beans), nuts, seeds, buckwheat, chia, and tofu. Green vegetables are also a good source of protein; for example, one cup of spinach contains 7 grams of protein. If you're looking for an extra hit of protein, sprouted/plant-based protein powder provides 23-26 grams of protein per 30-gram serving, which compares favourably to whey protein.
While the alkaline diet does not allow for meat, dairy, or eggs, it is important to ensure that you are meeting your nutritional needs. The strictest followers of the diet may need to supplement their protein, iron, and calcium intake to avoid potential health risks, such as loss of muscle mass, anemia, and poor bone health.
It is always recommended to talk to a doctor or dietitian about your health goals before beginning a new diet.

Monitor your urine pH
Monitoring your urine pH is a common practice for those following the alkaline diet. This is because the diet's theory claims that maintaining a constant blood pH requires the body to take alkaline minerals from bones to buffer acids from acid-forming foods. However, it is important to note that urine pH does not reflect a change in blood pH level.
The pH value measures how acidic or alkaline a substance is, with urine ideally falling between 6.0 and 7.5 on the pH scale. A wider range is usually acceptable, with any value within 4.5 to 8.0 being generally not a cause for concern. Urine pH can be tested using a litmus paper test, where a piece of specially treated paper called litmus paper is held in a urine sample and changes colour to indicate acidity or alkalinity.
While diet can change urine pH, it does not significantly affect blood pH in healthy individuals. Urine pH can be influenced by the balance of water, salts, and waste products from the kidneys present in the urine. Additionally, certain medications can make urine more acidic or alkaline.
Monitoring urine pH can provide insight into dietary acid-base load and indicate the intake of certain food groups, such as fruits, vegetables, and meats. However, it is not a direct indicator of overall health or blood pH levels.
It is recommended to speak with a healthcare provider before starting the alkaline diet or any restrictive diet to ensure it aligns with your health goals and does not unintentionally harm your health.

Add more alkaline-promoting foods
The alkaline diet is based on the theory that eating foods of a certain pH level can help prevent chronic diseases and improve health. However, it's important to note that there is limited research supporting these claims. According to the theory, the body takes alkaline minerals from bones to maintain a constant blood pH, which can lead to bone mineral density loss. Nevertheless, this theory does not consider the role of the kidneys and lungs in regulating blood pH.
Fruits and Vegetables: Most fruits and vegetables are considered alkaline-promoting. Focus on non-starchy vegetables like broccoli, beets, asparagus, leafy greens, garlic, carrots, and cabbage. Additionally, include antioxidant-rich berries like blueberries in your diet. These can be added to smoothies or salads and have been linked to improved heart health and cognitive function.
Legumes, Nuts, and Seeds: Legumes, such as beans, soybeans, and tofu, are excellent sources of plant-based protein in an alkaline diet. Include a variety of nuts and seeds in your meals as well.
Mangoes: Mangoes are a tropical fruit that are nutrient-dense, high in fiber, vitamins, and antioxidants. They are particularly beneficial for digestive health due to their high amylase content.
Lemon: Lemons are considered highly acidic, but once ingested, they break down into alkaline components that promote an alkaline environment in the body. They are rich in vitamin C and are known to improve digestive health, support cardiovascular health, and aid in weight management.
While the alkaline diet emphasizes these alkaline-promoting foods, it generally excludes dairy, eggs, meat, most grains, and processed foods. It is always recommended to consult with a healthcare professional before making significant dietary changes.
