Vegans tend to have significantly higher counts of certain beneficial bacteria, such as Bacteroidetes-related operational taxonomic units, and increased levels of lactic acid bacteria.

The study suggests that these changes in gut microbiota composition contribute to anti-pathogenic and anti-inflammatory effects, cardiovascular protection, improved immunity against pathogens, and regulation of critical functions of the intestine through the production of short-chain fatty acids.

A 2021 study authored by EA Losno, found that a vegan diet was associated with an increase in the abundance of Bacteroidetes on the phylum level and a higher presence of Prevotella on the genus level in the gut microbiota composition.

Can Vegan Diet Cause Hair Loss?

A well-planned vegan diet that includes a variety of whole plant-based foods is not likely to cause hair loss.

Hair loss is the condition characterized by the loss of hair from the scalp or other parts of the body.

There are some cases where hair loss may occur on a vegan diet, but it is not directly caused by the diet itself. Hair loss can be due to various factors, including nutrient deficiencies such as protein, iron, or zinc, which can be managed by ensuring a balanced and nutrient-rich vegan diet according to a 2019 study authored by HM Almohanna.

Individual experiences may vary, and hair loss may have medical or lifestyle-related causes, rather than being solely attributed to a vegan diet. It is essential for vegans to be mindful of their nutrient intake and ensure they are meeting their nutritional needs through a well-rounded and diverse diet. 

Can Vegan Diet Cause Acne?

A vegan diet may have the potential to cause acne or skin issues in some individuals according to a 2018 study authored by TJ Stewart.

Acne is a skin condition characterized by the presence of pimples, blackheads, and other blemishes on the skin, often occurring on the face, chest, and back.

Some potential reasons why acne may occur on a vegan diet include vitamin deficiencies, particularly low levels of B12 and zinc. A diet high in refined carbohydrates, such as pasta, sugar, bread, and white rice, can lead to higher serum glucose levels and increased sebum production, which can contribute to acne according to a 2019 study authored by A Pappas.

To address acne issues on a vegan diet, it is recommended to keep track of the foods you eat and observe how they impact your skin. Ensuring a well-balanced vegan diet that includes essential nutrients, such as B12, zinc, and vitamin A, may help prevent acne. If you experience persistent skin issues, consulting with a dietitian or dermatologist can provide personalized guidance and potential solutions.

Can Vegan Diet Cause Diarrhea?

Yes, some people experience diarrhea after going vegan is that this occurrence is relatively common and usually attributed to a sudden increase in fiber intake when transitioning to a plant-based diet.

Diarrhea is a condition characterized by the frequent passage of loose, watery stools, often accompanied by abdominal cramps and dehydration.

The body needs time to adjust to the higher fiber content, which can lead to loose stools. This adjustment period typically lasts for a week or two and should resolve on its own. It is best to reduce fiber intake initially and gradually increase it to ease the symptoms. Keeping a food journal and limiting certain foods like beans during the adjustment phase may also be helpful.

Can Vegan Diet Cause Diabetes?

A well-balanced vegan diet may actually reduce the risk of developing diabetes according to a 2017 study authored by M McMacken.

Diabetes is a chronic medical condition characterized by high blood glucose levels due to insufficient insulin production or ineffective use of insulin by the body.

Studies indicate that compared to individuals who consume more animal foods, vegetarians and vegans have a lower risk of developing diabetes. Adopting a plant-based diet can lead to decreases in blood sugar and blood pressure, especially if individuals are taking medications for these conditions.

Can Vegan Diet Cause Gout?

A plant-based vegan diet is not associated with an increased risk of gout according to a 2019 study authored by B Jakše.

Gout is a form of arthritis caused by the buildup of uric acid crystals in the joints, leading to sudden and severe joint pain, inflammation, and tenderness, often affecting the big toe.

While some plant foods may contain purines, which can contribute to gout, diets rich in plant foods have not been linked to gout or hyperuricemia. In fact, adopting a healthy plant-based diet can be beneficial for preventing gout and improving overall health. Plant foods are generally less concentrated in purines than meat and seafood, and the health benefits of a plant-based diet outweigh the potential risk of gout.

4 Benefits Of Probiotics

Probiotics can help with hair growth, acne, diabetes and gout according to research. Probiotics, including vegan probiotics offer numerous health benefits by promoting a balanced gut microbiome, improving digestion, boosting the immune system, and supporting overall well-being without the use of animal-derived ingredients.

1. Increasing Hair Growth

Probiotics found in Kimchi and Kefir have shown potential in helping with hair growth in Alopecia Areata. A 2020 study authored by DW Park revealed that probiotic supplementation through Kimchi and Cheonggukjang resulted in improved hair growth and reversal of hair loss in patients with alopecia.

Similarly, kefir, containing Lactobacillus probiotics, is believed to be beneficial for hair health due to its rich content of essential nutrients such as vitamin B7 (biotin) and other B-complex vitamins. 

These probiotics may improve blood flow to the scalp and have positive effects on the immune system, contributing to healthier hair. Incorporating these probiotics into the diet may potentially aid in managing hair loss and promoting hair growth for individuals with Alopecia Areata.

2. Improving Acne

Probiotics have shown potential in being beneficial for acne treatment. Studies suggest that probiotics, both when taken orally and applied topically, may help reduce skin eruptions and improve skin hydration.

These live microorganisms have antibacterial properties that can potentially decrease the severity and count of acne. The gut-skin axis highlights the connection between gut health and skin conditions like acne, and an imbalance in the gut microbiome may contribute to acne development. 

Probiotic strains such as Lactobacillus and Bifidobacterium have been found to be beneficial for acne management. They can help reduce inflammation, oxidative stress, rebalance gut dysbiosis, inhibit pathogenic bacteria on the skin, and maintain gut barrier integrity. 

Lactobacillus plantarum CJLP55 isolated from Kimchi, a fermented probiotic food, has been linked to improved acne lesion count and skin hydration. 

3. Improving Diabetes

The general consensus among experts is that diabetics can safely take probiotics and prebiotics. Probiotics have shown potential benefits for individuals with diabetes, such as lowering blood sugar levels and improving insulin sensitivity. Prebiotics, specifically Fructooligosaccharides, are also safe for diabetics, as they have no significant impact on blood sugar levels and can aid in blood sugar control and digestion. 

Both probiotics and prebiotics can positively impact gut health and overall well-being in individuals with diabetes. Type 1 and Type 2 diabetics can safely consume probiotics, including probiotic-rich yogurt, which has shown benefits for blood glucose levels and inflammatory markers in type 2 diabetes.

4. Improving Gout

Probiotics, particularly the strain Lactobacillus salivarius CECT 30632, have shown potential in reducing the number of gout episodes. These beneficial bacteria can degrade purines in the blood and help protect against kidney damage, which is relevant to managing gout. Gout is a painful form of arthritis that commonly affects the big toe.

Lactobacillus probiotics are commonly found in supplements and fermented foods and are known for promoting gut health and balance. Incorporating these probiotics into one's diet may offer benefits in managing gout and reducing its symptoms.
