I've always been interested in the relationship between nutrition and appearance, I first learned about this concept from Cara Oates, her Inner Beauty Glow Powder was the first product I stocked in my store, back in 2011. Researchers are exploring the fascinating connections between digestive health and skin appearance (Gut-Skin Axis), studying how different aspects of nutrition may influence skin characteristics like hydration, tone, and ageing patterns. While toxin-free skincare is important, many people are also looking at nutritional approaches to skin appearance.
What is the Gut-Skin Axis?
According to scientific research (Thye et al., 2022; De Pessemier et al., 2021), the Gut-Skin Axis refers to the bidirectional communication network between the gastrointestinal system, particularly its resident microbiota, and the skin, involving complex interactions through immune, metabolic, and neuroendocrine pathways that influence skin homeostasis.
In simpler terms, think of it like a relationship between digestive processes and skin appearance. Research is examining how the balance of bacteria living in the digestive system might relate to various skin characteristics. If digestive function changes, researchers are studying whether this might correlate with changes in skin appearance.
"We believe that 'Beauty begins in the belly' - that when you are healthy on the inside, your skin radiates a natural glow that no amount of cosmetics can replicate," explains Carla Oates, founder of The Beauty Chef and a pioneer of inside-out beauty.
This area of research into the relationship between digestive health and skin appearance explains why some people find that topical products alone don't address all their skin concerns. By understanding these connections, research is moving toward holistic approaches to skin appearance.
Current Research on Digestive Health and Skin Appearance
Scientists are studying how the balance of microorganisms in the digestive system might be associated with various skin characteristics. One area of interest is intestinal permeability, where researchers examine how the integrity of the digestive lining might relate to systemic processes. According to research published in Frontiers in Immunology (Thye et al., 2022), there may be associations between digestive health markers and certain skin conditions.
"The gut is the foundation of our wellbeing. It's where 70 per cent of our immune system lies," explains Carla Oates. "If any of these processes are knocked out of balance, it can profoundly affect our wellbeing including our skin health."
Beyond these relationships, researchers are examining how nutrient absorption might play a role in skin appearance. Vitamins A, C, E, and zinc are involved in skin metabolism, collagen production, and protection against environmental factors. Additionally, scientists are studying how digestive processes may influence how the body processes various compounds, and whether this might relate to skin appearance. Research has observed that people with certain skin characteristics sometimes have different levels of particular gut bacteria like Akkermansia muciniphila and Faecalibacterium prausnitzii (De Pessemier et al., 2021), highlighting the complexity of these relationships.
Nutrition Considerations: 4 Areas of Interest in Skin Health Research
Many people are interested in approaches to digestive health. It's important to remember that if you're experiencing any digestive symptoms or discomfort, consulting a healthcare practitioner is advisable as they can test for conditions that require professional treatment.
1. Dietary Diversity
Research suggests that variety may be beneficial for the bacterial populations in the digestive system. Including different types of plant foods such as vegetables, fruits, nuts, seeds, legumes, herbs, and spices may support microbial diversity, which some researchers associate with various health parameters.
According to research that examined over 21,000 individuals, people who eat at least 30 different plant foods per week show significantly greater microbial diversity than those who consume 10 or fewer types of plant foods.
2. Gut Barrier Function
The integrity of the digestive lining is an active area of research. Nutrients such as zinc, vitamin A, and vitamin D have been studied for their role in maintaining tissue barriers. Proper hydration is also being researched for its importance in maintaining the protective mucus layer that lines the digestive tract.
Some studies have looked at various food groups and their relationship to digestive health: whole grains, fruits, vegetables, nuts and seeds, legumes, and herbs and spices contain compounds called prebiotics that may influence the composition of gut bacteria.
3. Stress and Digestive Function
Many people notice skin changes during stressful periods, which has led researchers to investigate the gut-brain-skin relationships. Psychological stress may influence digestive function and microbiome composition, which some researchers suggest could affect skin appearance. Mind-body practices like meditation, yoga, or simple deep breathing exercises are being studied for their potential effects on stress hormone levels.
4. Nutritional Supplements
While whole foods provide the foundation of nutrition, certain supplements are also being studied for their potential roles in digestive and skin health, including probiotics, prebiotics, and collagen.
The Beauty Chef range (created by Carla Oates) was among the early entries in the inner beauty supplement category. Founded in 2009, The Beauty Chef created interest in the potential connection between digestive health and skin appearance with their first iteration of Glow.
The Beauty Chef products contain pre, pro and postbiotic ingredients developed by a team of microbiologists, naturopaths and nutritionists. The original Beauty Chef glow has been refined over the years with the current formulation containing their exclusive Hyaluronic Complex™ of sea buckthorn, grapeseed extract & hyaluronic acid.
"Clear, glowing skin occurs when you feed your body nutrient-dense food and cultivate a healthy microbiome the mini ecosystem that lives inside each one of us and is home to trillions of microorganisms and over 1000 species of bacteria," explains Carla. For those interested in skin clarity, The Beauty Chef Clear Skin Inner Beauty Support contains vitamin A which contributes to skin maintenance, vitamin B5 which is involved in steroid hormone synthesis, vitamin C which has antioxidant properties, and zinc which plays a role in wound-healing, along with broccoli sprout, burdock, dandelion, echinacea, probiotics and digestive enzymes.
Another notable product in this category is from Lee Holmes, a holistic nutritionist and author of bestselling books including "Supercharged Food: Eat Your Way to Health" and "Supercharged Food: Eat Yourself Beautiful." Her Supercharged Food Love Your Gut Powder contains Diatomaceous Earth with Silica plus 13 trace minerals. This superfine powder can be added to water, juice, or smoothies.
Approaches to Digestive Health
You can begin paying attention to your digestive health with your very next meal. As long as you've consulted with a healthcare practitioner about any underlying concerns, you might consider:
- Including a variety of fibre-rich plant foods
- Exploring fermented foods containing live cultures
- Maintaining adequate hydration
- Practising stress management techniques like meditation or mindfulness
- Prioritising sufficient sleep
- Being mindful of processed foods, sugar, and alcohol consumption
- Learning about products like Love Your Gut powder or The Beauty Chef GLOW
Consistency is important - dietary changes can begin to influence your microbiome within days, though more significant changes typically require longer commitment.
The Relationship Between Nutrition and Appearance
Scientific research continues to explore the fascinating connections between digestive health and skin appearance. The gut-skin relationship represents an intriguing area of study that looks at underlying factors that may influence skin characteristics. By considering dietary diversity, supporting digestive barrier function, managing stress, and learning about nutritional supplements, many people are taking an interest in both their digestive health and skin appearance.
