The alkaline diet is based on the idea that eating certain foods can alter the pH of your body, moving it to the alkaline side of the scale. It involves eating alkaline or low-acid foods like fruits and vegetables, soybean, tofu, nuts, seeds and legumes, while minimising intake of acid-forming foods like meat, eggs, dairy, grains and processed foods. The diet is said to optimise pH levels in the body, lower disease risk and promote weight loss, but there is little evidence to support these claims.
Characteristics and Values of an Alkaline Diet

The alkaline diet is based on the idea that eating certain foods can alter your body's pH level
The alkaline diet, also known as the acid-alkaline or alkaline ash diet, suggests that replacing acid-forming foods with alkaline foods can improve health. Proponents of this diet argue that the metabolic waste left behind after food is converted into energy affects the body's acidity. While the diet may support health by limiting processed foods and promoting whole foods, it does not alter the body's pH levels.
The pH value measures the acidity or alkalinity of a substance, with a pH scale ranging from 0 to 14. A pH of 0-6 is considered acidic, 7 is neutral, and 8 or higher is basic or alkaline. While the stomach is very acidic, with a pH of 1.5-2, the blood is slightly alkaline, ranging from 7.35 to 7.45, and is tightly regulated by the body.
The alkaline diet generally includes nutrient-dense, plant-based, and unprocessed foods, such as fruits and vegetables, soybeans, tofu, nuts, seeds, and legumes. It discourages or limits neutral foods like natural fats, milk, and sugars, as well as acidic foods like dairy, eggs, meat, grains, and processed foods. While the diet may be challenging to follow due to its restrictions and the difficulty of eating out, it can provide health benefits similar to those of a healthy, balanced diet.
While the alkaline diet may not significantly alter the pH level of the blood, it can change the pH of urine. However, urine pH is not a reliable indicator of overall body pH or general health. It is always recommended to consult a doctor or dietitian before starting a new diet to ensure it aligns with your health goals and nutritional needs.

It encourages eating alkaline, or low-acid foods like fruits and vegetables
The alkaline diet is based on the idea that eating certain foods can alter the pH of your body. It encourages eating alkaline or low-acid foods like fruits and vegetables, which are believed to have health benefits. The diet includes fresh, nutrient-dense foods and promotes whole foods while limiting processed foods.
Fruits and vegetables are alkaline-promoting foods, and most of them fall under this category. This includes non-starchy veggies like broccoli, beets, asparagus, leafy greens, garlic, carrots, and cabbage. Citrus fruits like oranges, which are naturally acidic, are also considered basic on the alkaline diet. These foods are rich in potassium and low in sodium, which helps lower blood pressure levels.
However, it is important to note that the claim that the alkaline diet can change your body's pH level is unproven. While the diet may promote healthy eating habits, it is not proven to directly affect your body's pH. The pH of your blood needs to remain constant for you to stay healthy, and your body has effective ways to regulate it. Food typically does not cause a significant change in blood pH, although it can change the pH of your urine.
While the alkaline diet may not directly affect your body's pH as claimed, it can still offer health benefits. It emphasizes nutritious and unprocessed foods, which can positively impact your overall health. It also encourages a higher intake of fruits and vegetables, which are associated with a lower risk of diseases. Additionally, the alkaline diet can support heart health by minimizing fatty animal foods and emphasizing fiber-rich plant foods, which help lower LDL cholesterol levels.

It discourages eating animal proteins, dairy, grains, and processed foods
The alkaline diet is based on the idea that consuming alkaline foods can alter the pH of your body, making you healthier. However, it's important to note that the claim that the diet can change your body's pH is unproven. While the diet may not significantly affect blood pH, it can still have positive effects on your overall health.
The alkaline diet discourages the consumption of animal proteins, dairy, grains, and processed foods. It is similar to a vegan diet in that it excludes animal products, including meats, eggs, and dairy. These foods are considered acidic or acid-forming and are, therefore, restricted in the alkaline diet. Dairy, eggs, and meat are also considered to be on the acidic side and are not recommended in the alkaline diet.
The diet also discourages the consumption of grains, especially gluten-containing grains like wheat. To completely avoid gluten, it is necessary to carefully check food labels, as gluten can be present in various processed foods. Processed foods, such as canned and packaged snacks, are not allowed in the alkaline diet because they are considered highly acidic and lacking in nutritional value.
The alkaline diet emphasizes whole foods and nutrient-dense options. It encourages a diet rich in fruits and vegetables, which are considered alkaline-promoting and provide various health benefits. These include lowering disease risk, reducing inflammation, and supporting heart health by lowering cholesterol and blood pressure levels. However, it is important to note that a strict alkaline diet that eliminates all proteins and grains is neither necessary nor recommended, as it may increase the risk of nutrient deficiencies.

It may support heart health by minimizing fatty animal foods and emphasizing fiber-rich plant foods
The alkaline diet is based on the idea that consuming alkaline-rich foods can improve health by altering the body's pH level. However, it's important to note that the link between dietary acid load and cancer has not been established. While cancer cells thrive in acidic environments, they create this acidity themselves, and cancer can also develop in alkaline environments.
The alkaline diet recommends eating alkaline or low-acid foods, such as fruits and vegetables, while limiting acidic foods like meat, dairy, eggs, and processed foods. This shift can support heart health by reducing the consumption of fatty animal products and increasing fiber-rich plant-based options.
By minimizing fatty animal foods, the alkaline diet helps lower low-density lipoprotein (LDL) cholesterol levels, which is a key risk factor for heart disease. High LDL cholesterol levels, also known as "bad" cholesterol, can be detrimental to heart health. The reduction of fatty animal foods in the alkaline diet contributes to lowering these levels and promoting better cardiovascular health.
In addition to minimizing fatty animal foods, the alkaline diet emphasizes the inclusion of fiber-rich plant foods. This emphasis on plant-based sources of fiber helps to further reduce LDL cholesterol levels. One study found that individuals following a lower PRAL (potential renal acid load) diet, which is more alkaline, were more likely to meet national dietary guidelines for heart-healthy nutrients. These individuals consumed higher levels of fiber and potassium while reducing their intake of saturated fat, which is known to increase LDL cholesterol.
The alkaline diet's focus on fiber-rich plant foods also contributes to lowering blood pressure levels. Alkaline foods, such as fresh fruits and vegetables, are naturally rich in potassium and low in sodium. This combination of increased potassium and reduced sodium intake is beneficial for regulating blood pressure, which is an important aspect of maintaining heart health.
While the alkaline diet may not significantly alter the pH level of the blood, as claimed, it can still offer health benefits. By minimizing fatty animal foods and emphasizing fiber-rich plant foods, the alkaline diet may support heart health by lowering LDL cholesterol levels and helping to maintain healthy blood pressure.

While it may not change your body's pH level, it can still be healthy
The alkaline diet is based on the idea that consuming alkaline-forming foods can alter the pH of your body, making you healthier. It involves eating alkaline or low-acid foods like fruits and vegetables, soybean, tofu, nuts, seeds, and legumes, while avoiding animal proteins, dairy, and grains and limiting processed foods. The diet has gained popularity due to its supposed health benefits, including weight loss and the prevention of diseases like arthritis and cancer.
While the alkaline diet may not significantly alter your body's pH level, it can still offer health benefits. Firstly, the diet promotes the consumption of whole foods and limits processed foods, which can contribute to a healthier lifestyle. Secondly, the alkaline diet encourages a higher intake of fruits and vegetables, which are rich sources of antioxidants and phytochemicals, as well as potassium and fiber. This can lead to reduced inflammation, lower disease risk, and improved heart health. Additionally, the diet may help cancer patients feel their best and better tolerate treatment, although it is important to note that there is no specific diet or food that can cure cancer.
It is worth mentioning that the alkaline diet can be restrictive, and stricter versions may increase the risk of nutrient deficiencies. Therefore, it is always recommended to consult a healthcare professional or dietitian before starting any new diet to ensure it aligns with your health goals and nutritional needs.
While the alkaline diet may not directly change your body's pH level as claimed, adopting this diet can still provide health benefits and support overall well-being. However, it is important to approach it with caution and ensure that it is tailored to meet your individual nutritional requirements.
