Plant-Based Diets: Skin Health Benefits Revealed

A plant-based diet can be beneficial for skin health and inflammatory skin diseases. Plant-based diets are rich in bioactive compounds, including vitamin C, vitamin E, beta carotene, polyphenols, and phenolic acids, which can contribute to oxidant defence, lower inflammation, and promote structural support of the skin.

The human skin is a crucial organ that protects the body from the outer environment. Skin integrity and health depend on both intrinsic and extrinsic factors. While intrinsic factors such as ageing and genetic background contribute to weakened skin, extrinsic factors like UV radiation, pollution, smoking, humidity, and poor diet also affect skin health.

A plant-based diet is defined as a diet based on plant foods, including vegetables, fruits, beans, lentils, legumes, nuts, seeds, fungi, and whole grains, with limited or no animal products or processed foods. Research has shown that these diets have beneficial effects on inflammatory skin diseases.

Additionally, certain plant-based functional foods, when incorporated into the diet, have beneficial effects on skin health. These include mangoes, almonds, and avocados, which can reduce wrinkles, improve skin elasticity, and provide photoprotection.

Overall, a plant-based diet can be a potential therapeutic option for maintaining skin health and managing specific skin conditions.

The impact of a plant-based diet on inflammatory skin diseases

A plant-based diet is defined as a diet based on plant foods, including vegetables, fruits, beans, lentils, legumes, nuts, seeds, fungi, and whole grains, with limited or no animal products or processed foods. The human skin is an organ that is exposed to the outer environment and has functions such as body temperature regulation, protection against infections, and preservation of internal organs. Skin health depends on both intrinsic and extrinsic factors. While intrinsic factors include ageing and genetic background, extrinsic factors include UV radiation, pollution, smoking, humidity, and poor diet.

Plant-based diets and inflammatory skin diseases

Plant-based diets have gained popularity as a complementary therapy for skin health and have been shown to have beneficial effects on inflammatory skin diseases. These diets can modulate inflammatory and oxidative processes, which are the main mechanisms in inflammatory skin diseases.

Psoriasis

Psoriasis is a chronic immune-mediated skin disease characterised by scaly, erythematous plaques. It is now known to be a systemic pathology, with a persistent inflammatory state, that affects multiple organs and results in a significant decrease in quality of life. A cohort study investigated dietary behaviours in patients with psoriasis and found that 86% of respondents made changes to their diet, noting that the best positive results on skin improvement were observed with vegan, Pagano, and Paleolithic diets. Dairy and sugar consumption was reported as one of the most common triggers for psoriasis, while meat and eggs were included as one of the minor common triggers.

Atopic Dermatitis

Atopic dermatitis (AD) is the most common inflammatory skin disease, characterised by erythema papules and pruritic scaly plaques. A recent cross-sectional study investigated the relationship between adults with AD and lifestyle factors such as diet, and found no association between diet, specifically vegetarian and vegan diets, and the presence or severity of AD. However, a controlled clinical trial found that a vegetarian diet significantly decreased the SCORAD (scoring atopic dermatitis) index.

Acne

Acne vulgaris is the most common form of acne, defined as a chronic inflammatory skin disease that affects the pilosebaceous unit. A study investigated the association between dairy intake and acne and reported an increased risk of developing moderate to severe acne with the regular consumption of low-fat and whole milk. Another study determined the relationship between dietary factors and acne in young adults and found an increased intake of meat, beef, fish, butter, honey, corn, rice, chicken, and pizza in acne patients compared to controls, and conversely, a higher consumption of vegetables and potatoes in the control group.

In conclusion, plant-based diets have been shown to have beneficial effects on inflammatory skin diseases such as psoriasis, AD, and acne. These diets can modulate inflammatory and oxidative processes and provide anti-inflammatory properties, resulting in an improvement in the general life condition of patients. However, more studies are needed to further understand the role of plant-based diets in the management of inflammatory skin diseases.

The role of plant-based functional foods on skin health

The skin is the body's largest organ and acts as a protective barrier against external factors. Skin health depends on both intrinsic and extrinsic factors, with the latter including UV radiation, pollution, smoking, and diet. Plant-based diets have gained popularity as a complementary therapy for skin health, with research showing beneficial effects on inflammatory skin diseases. This article will explore the role of plant-based functional foods in promoting skin health and their potential benefits.

Plant-Based Functional Foods

Plant-based functional foods are defined as foods that provide health benefits beyond basic nutrition due to their active substances. These foods are rich in bioactive compounds such as vitamin C, vitamin E, beta carotene, polyphenols, and phenolic acids, which can contribute to antioxidant defence, lower inflammation, and promote skin structure. Examples include mangoes, almonds, and avocados.

The Benefits of Plant-Based Functional Foods on Skin Health

Mangoes

Mangoes are an excellent source of vitamin C, B-carotene, xanthones, and phenolic acids. Vitamin C is a powerful antioxidant that stimulates collagen and elastin synthesis, protecting the skin from UV-induced damage and preventing photoaging. B-carotene, a precursor of vitamin A, also provides photoprotection. Studies have shown that mango extract can reduce wrinkle formation, inhibit collagen loss, and improve skin elasticity.

Almonds

Almonds are rich in vitamin E, fatty acids, and polyphenols, making them effective in reducing wrinkles, hyperpigmentation, and collagen degradation. Studies have demonstrated that almond consumption can improve skin elasticity and reduce wrinkle severity and facial pigmentation without increasing sebum production.

Avocados

Avocados contain carotenoids, monounsaturated fatty acids, and phenols, which have beneficial effects on skin health. Avocado consumption has been shown to improve skin elasticity and firmness, particularly in the forehead and under-eye areas.

Plant-based functional foods, such as mangoes, almonds, and avocados, have been shown to have positive effects on skin health. These foods provide essential nutrients and antioxidants that can protect against UV damage, reduce inflammation, and improve skin structure. Further research is needed to fully understand the potential benefits of these foods and determine optimal intake levels.

The link between the gut microbiome and plant-based diets in relation to skin health

The gut microbiome is an important factor in skin health. The gut and the skin are closely linked, with the former influencing the latter's homeostasis and biology. The gut microbiome can influence skin health through the production of metabolites such as short-chain fatty acids (SCFAs), neurotransmitters, tryptophan derivatives, and bile acids. These metabolites can reach the skin and influence its physiology.

A healthy gut microbiome is characterised by a diverse range of bacteria, with a higher abundance of beneficial bacteria. Plant-based diets have been shown to increase the diversity of the gut microbiome and promote the growth of beneficial bacteria. In contrast, Western diets have been associated with a decrease in beneficial bacteria and an increase in harmful bacteria, leading to dysbiosis, or an imbalance in the microbiome.

The impact of plant-based diets on the gut microbiome

Plant-based diets are defined as diets that consist primarily of plant-based foods, including vegetables, fruits, beans, legumes, nuts, seeds, fungi, and whole grains, with limited or no animal products or processed foods. These diets are often associated with health benefits, including a reduced risk of cardiovascular disease, obesity, and other health issues.

Plant-based diets have been shown to have beneficial effects on the gut microbiome. They increase the abundance of beneficial bacteria, such as the phylum Bacteroidetes, and promote a diverse range of bacteria. This can lead to improved gut and overall health.

The impact of the gut microbiome on skin health

The gut microbiome has been linked to various skin conditions, including acne, psoriasis, and atopic dermatitis. Imbalances in the gut microbiome, or dysbiosis, can lead to increased intestinal permeability and the release of pro-inflammatory cytokines, which can contribute to skin inflammation and the development of skin diseases.

A healthy gut microbiome is associated with improved skin health. A diverse gut microbiome, characterised by a variety of beneficial bacteria, is linked to lower levels of inflammation and a reduced risk of certain chronic diseases.

The role of plant-based diets in improving skin health

Plant-based diets have been shown to have beneficial effects on skin health, particularly in the context of inflammatory skin diseases. These diets can help to modulate inflammatory and oxidative processes, which are key mechanisms in inflammatory skin diseases.

Plant-based diets can also provide a variety of plant-based functional foods, which contain additional components that can contribute to overall skin health. For example, mango, almond, and avocado are known to have positive effects on the skin, including reducing wrinkles, improving skin elasticity, and protecting against UV damage.

The gut-skin axis and the role of plant-based diets

The gut-skin axis refers to the bidirectional interaction between the gut and the skin. Imbalances in the gut microbiome, often caused by Western diets, can lead to skin inflammation and the development of skin diseases.

Plant-based diets have been shown to improve the composition of the gut microbiome and promote the growth of beneficial bacteria. This can have a positive impact on skin health, leading to healthier skin and a reduced risk of skin diseases.

In conclusion, there is a clear link between the gut microbiome and plant-based diets in relation to skin health. Plant-based diets can improve the composition of the gut microbiome, leading to a diverse and healthy gut microbiome, which in turn can influence skin health and reduce the risk of skin diseases.

Plant-Based Diets and Specific Skin Conditions

Psoriasis

Psoriasis is a chronic immune-mediated skin disease characterised by scaly, erythematous plaques. Dietary interventions, such as vegan, Pagano, and Paleolithic diets, have been shown to have positive effects on skin improvement in patients with psoriasis. Dairy and sugar consumption are common triggers for psoriasis, while the avoidance of junk food, white flour products, and red meat has also been found to have beneficial effects.

Overweight and obesity are risk factors for the development of psoriasis. Weight loss and a reduction in Body Mass Index (BMI) have been associated with clinical improvement in psoriasis patients. Plant-based diets, such as the vegan diet, can contribute to weight loss and a reduction in BMI, thereby indirectly improving psoriasis symptoms.

Atopic Dermatitis

Atopic dermatitis (AD) is a common inflammatory skin disease characterised by erythema papules and pruritic scaly plaques. While there is no direct association between a plant-based diet and the presence or severity of AD, obesity, a diet-related disease, has been positively linked to moderate to severe AD.

A vegetarian diet has been found to decrease the severity of AD by reducing immunological parameters such as LDH5 activity, the number of peripheral eosinophils, and PGE2 synthesis, which are responsible for skin inflammation. Additionally, a vegetarian diet can reduce oxidative DNA damage and provide a high nutritional intake of vitamins and antioxidants, which may play a role in reducing skin inflammation.

Acne

Acne vulgaris is a common form of acne characterised by skin lesions, including comedones, papules, pustules, nodules, and cysts.
