Is a vegan diet alkaline?

In this brief guide, we will answer the query, “Is a vegan diet alkaline?” and will discuss what an alkaline diet is and why body pH is important?

Is a vegan diet alkaline?

No, a vegan diet is not alkaline. The majority of alkalarians are vegans, however, vegans are not usually alkalarians. All-natural plant-based meals are consumed in an Alkaline diet, as well as the usage of solely electric herbs to promote health and wellbeing. An alkaline diet does not include any animal or animal-based goods (such as meat or fish), no dairy products, eggs, or honey.

To be classified as a vegan, one must abstain from eating any animal or animal product. You can’t eat anything made from animals — not even dairy or eggs — if you’re vegan. However, some vegans may be able to eat honey.

Vegan diets are becoming more popular. A survey commissioned by the Vegan Society, and organized by the UK’s Food Standards Agency and National Centre for Social Science research showed an estimated 400% increase in people following vegan diets between 2014 and 2019 in the UK. This would account for an estimated total of 600,000 people in the UK during that period (4).

What is a vegan diet?

A vegan diet does not include any animal products, such as dairy, meat, fish, or honey; rather, it excludes all animal products. It’s all about animal welfare and the environment with this diet. In a vegan diet, every food is made from plants alone. A plant-based diet may be helpful for your health, but a vegan diet isn’t usually particularly healthy (2).

The foods consumed in a vegan diet are not necessarily nutritionally favorable or health-promoting. The foods consumed may include vegetables, legumes, fruit, nuts, seeds, valuable plant oils or whole-grain products, all of which have been shown to have favorable effects. If however high levels of sugar, fat or table salt are added to vegan dishes, then they are nutritionally unfavorable (2).

 Fast-food vegans are a common sight around here. For some reason, they continue to consume large amounts of sugar and processed foods. For instance, vegan Oreo cookies are available, but we all know how unhealthy they are. The vast majority of bread on the market is vegan. In many cases, bread does nothing more than fill you up and clog your intestines. What about meat substitutes? Food that’s been through a lot of processing and is loaded with toxins. So, it’s not always the case that veganism is healthy.

What is an alkaline diet?

The blood pH is normally maintained in the range of 7.35-7.45. The arterial blood is more alkaline and has a higher oxygen content than venous blood. If blood pH goes below 7.35, it is said to be acidic (acidemia), and if it goes above 7.45, it is alkalotic (alkalemia). A pH distant from this normal range means there is a severe, sometimes life-threatening acid-base disorder. As by-products of cellular respiration, some foods may form acidic cell metabolic wastes (so-called acid-forming foods) and some may form alkaline cell metabolic wastes (so-called alkaline-forming foods), both temporarily affecting pH in some cellular environments and in blood compartments. Therefore, some natural healers believe that acid-forming foods may play a large role in this, while alkaline-forming foods may be preventative. However, the alkalizing characteristics of fruits may depend on their content and composition and can even be affected by various production and harvest-related factors (1).

An alkaline diet, on the other hand, uses oils (which are always cold-pressed and not heated) and prepares everything from scratch, but they also avoid all forms of sugar, fungus, and yeast wherever possible.

Mango and pineapple are examples of high-sugar fruits; fungus and yeast refer to fermented meals, as well as risen bread.

It is the goal of alkalarians to keep the body’s pH in balance so that it does not overwork. All of the body’s efforts are focused on maintaining a blood pH of 7.365. Acidic meals (stuff that is low in pH when ingested) cause the body to do all it can to maintain a proper blood pH level when consumed. The acidity will have to be eliminated. When the body is not overworked and hydrated, this works nicely. Defecation, urine, transpiration, and breathing all help to flush the acid out of the body.

However, it is very difficult to define whether a food has an alkalizing or an acidifying effect in the blood. Understanding the acid and alkaline forming character of foods (independent from the original pH of the food or drink) requires measuring which foods have which kind of corresponding effect. One method would be to measure the pH of urine or saliva following consumption of each type of food. However, this is an indirect measurement and not very accurate because some of the metabolic wastes such as carbon dioxide leave the body via the lungs and blood acidity may partly be neutralized by bone calcium compounds; acidity of the saliva is usually neutralized by the teeth; and some acids are excreted via sweating (1).

Isn’t it better if we consume acidic meals and don’t drink enough water? The body becomes too acidic. It takes around 36 glasses of water for the body to neutralize one glass of coke (pH 2), for example, Toxic levels of acidity may cause anything from lethargy to diabetes and auto-immune illness, among many other health issues.

What to Eat and What to Avoid in an Alkaline diet?

Soybeans and tofu, as well as various nuts, seeds, and legumes, are all alkaline-promoting foods that may be eaten in moderation. Acidic foods, such as dairy, eggs, meat, most cereals, and processed meals like canned and packaged snacks and convenience foods, are not permitted. In most literature promoting the alkaline diet, alcohol and caffeine are also discouraged.

The ingestion of fruits and vegetables may cause an alkalinization of the body and therefore fits into the alkaline diet. However, the alkaline diet limits the ingestion of some specific fruits and vegetables. Spinach, sorrel, chard, beetroot, peas, and sweet corn should be avoided. Green leafy vegetables, for example, kale, broccoli, brussel sprouts, cabbage; onions, garlic, celery, zucchini, rutabaga; salad vegetables, for example, lettuce, cucumber, radish, bell pepper, arugula and sprouted seeds are to be ingested to 3-4 portions a day. Fruits are recommended to 2-4 portions a day and potatoes to 1 portion a day. Oils and sugar are free (3). 

What is the significance of pH, and why is it so critical?

Any pH lower than 7.0 is considered acidic and is associated with a slew of health issues. Toxins are not removed from the body as effectively in an acidic state, resulting in a buildup of toxins throughout the body, which further impairs the body’s ability to function; in an alkaline state, tissues repair and regenerate more effectively, elimination is not as efficient, and cells do not receive the oxygen they need. Oxygen deprivation in a cell is like a fish without water, and we all know what that entails. Insulin sensitivity and artery cholesterol buildup have both been related to high levels of excess acid in the blood.

In traditional systems of medicine, foods that tend to form acidic metabolic waste, such as animal protein, are thought to cause certain health problems when predominant in the diet. Foods that form predominantly alkaline metabolic waste are believed to improve health and are even used in treatments for some diseases. But modern research is also beginning to confirm that these dietary differences do indeed influence the acid-base balance of several body compartments (1).

Does the alkaline diet work well in certain circumstances?’

When following an alkaline diet, you should eat more fruits and vegetables than high-calorie, high-fat foods. You’ll also avoid ready-to-eat meals, which are generally high in salt. The good news for heart health is that these actions help decrease blood pressure and cholesterol, two major risk factors for cardiovascular disease.

Obesity and osteoarthritis may both be prevented and treated by maintaining a healthy weight. Alkaline environments have been linked to improved efficacy and reduced toxicity in several chemotherapy treatments. Alkaline diets have not been shown to accomplish this or prevent cancer. Talk to your doctor or nutritionist before embarking on a new diet if you have cancer. 

According to research studies, increased consumption of alkaline forming foods maintains the high oxygen saturation in the blood that may reduce the incidence of non-communicable diseases, such as heart attacks and stroke), cancers, chronic respiratory diseases (such as chronic obstructive pulmonary disease and asthma) and diabetes (1). In addition, it prevents kidney damage. A more alkaline diet will reduce the accumulation of acid and reduce the metabolic complications associated with kidney diseases, such as muscle wasting, bone disease, and insulin resistance (3).
