Alkaline diet: Assertions, truths, and edibles
In the United States, heart disease remains the leading cause of death, with lifestyle factors such as poor nutrition and low activity levels being major contributors. Amidst this health crisis, a growing body of evidence suggests that adopting an alkaline diet could offer significant benefits in weight management and the prevention of chronic diseases.
The alkaline diet, characterised by a focus on fruits, vegetables, legumes, and nuts, is believed to promote a healthy body weight and lower heart disease risk factors due to its low-fat and low-calorie nature. However, it is important to clarify that the primary health benefits of an alkaline diet are not derived from altering systemic blood pH, as the body tightly regulates this parameter.
Studies have found that plant-based diets, which tend to be more alkaline, are associated with significant weight loss, improved insulin sensitivity, and lower blood pressure. For instance, a randomized trial showed a low-fat vegan diet reduced dietary acid load and resulted in a 13-pound weight loss over 16 weeks, compared with no weight change on a Mediterranean diet.
An alkaline-rich diet has also been linked to a lower risk of chronic diseases such as heart disease, diabetes, and certain cancers. The dietary acid load may influence metabolic acidosis and inflammation, which are pathways involved in these conditions.
Some research suggests that maintaining an optimal alkaline environment can support cellular function and enhance fat metabolism. There is also evidence that alkaline diets contribute to improved bone health, possibly by reducing acid-induced bone resorption.
It is worth noting that the body maintains blood pH within a narrow range through respiratory and renal mechanisms, so dietary changes do not significantly alter blood pH directly. The health benefits are thought to derive from the quality and composition of foods (rich in alkaline minerals and nutrients), rather than systemic alkalization.
A small amount of research suggests that supplementing the diet with alkaline minerals might help with symptoms of back pain. Eating more fruits and vegetables may also improve bone health, as alkaline diets are rich in these foods.
Reducing or eliminating red and processed meats from the diet, a common feature of alkaline diets, may lower heart disease risk. For people with chronic kidney disease, a lower-acid diet may offer health benefits.
In conclusion, the scientific evidence supports that alkaline diets contribute to weight management, improved metabolic markers, and reduced risk of chronic conditions primarily by promoting healthy food intake patterns and reducing dietary acid load, rather than by changing blood pH itself. Individuals interested in trying an alkaline diet should focus on eating more low-acid foods such as fruits, vegetables, seeds, legumes, tofu, and lentils, and avoid high-acid foods such as dairy products, processed foods, fish, coffee, alcohol, and soda.
