Psoriasis is not just a skin or joint condition—it’s a systemic inflammatory disease that affects multiple systems in the body. People living with psoriasis often face additional health challenges like obesity, cardiovascular disease, diabetes, and depression. These conditions, known as comorbidities, share a common link: systemic inflammation.
Diet plays a crucial role in managing psoriasis and overall inflammation. While Ayurveda has long emphasized the importance of diet and lifestyle in chronic conditions, modern medicine is beginning to recognize this connection, supported by emerging research. However, studying the impact of diet on diseases like psoriasis is challenging because controlling all influencing factors in large-scale human trials is difficult.
The Science Behind Diet and Psoriasis
Recent research has shed light on how diet influences psoriasis. In one study, mice fed a diet high in fats and sugars for just four weeks showed skin changes similar to psoriasis. When specific psoriasis triggers were introduced, the inflammatory skin changes were quicker and more severe. Interestingly, these changes were less pronounced in mice fed only fats, suggesting sugar might be the primary dietary culprit.
When the mice were switched to a healthier diet rich in fiber, healthy fats, and minimal sugar, the inflammation resolved significantly. This highlights the powerful role of diet in both triggering and managing inflammatory conditions like psoriasis.
Gut-Skin Connection
Another area of emerging research is the gut-skin axis, which explores how the health of the gut microbiome impacts the skin. A diet high in sugar and unhealthy fats has been shown to alter the gut microbiome, creating a microbial environment similar to that observed in people with psoriasis. This suggests a clear link between what we eat, gut health, systemic inflammation, and skin health.
What Should a Balanced Diet for Psoriasis Look Like?
While there’s no one-size-fits-all answer, a general guideline for a psoriasis-friendly diet includes:
Low sugar: Minimize direct and hidden sugars in food.
Healthy fats: Incorporate sources like nuts, seeds, and vegetable oils.
Adequate protein: Choose high-quality protein from plant or lean animal sources.
High fiber: Eat plenty of vegetables, fruits, and whole grains.
Calorie restriction or a low-calorie diet has also shown promising results in reducing inflammation. Most adults need around 2,000 to 2,500 K calories per day, but consuming 900 to 1,500 K calories in a controlled, balanced manner has been associated with improvements in psoriasis. Alternatively, regular exercise and physical activity can help balance calorie intake and expenditure. In simple terms: Eat less and move more.
The Ayurvedic Perspective
Ayurveda has always emphasized the importance of treating the gut and optimizing digestion as the foundation of managing diseases like psoriasis. According to Ayurvedic principles, digestion, absorption, and elimination must function properly for overall health.
Moreover, Ayurveda advocates for personalized diet plans based on an individual’s unique body constitution (prakruti) and specific condition. Not just what you eat, but how you eat matters. Eating mindfully, at the right times, and in the right quantities is key to achieving balance.
As Ayurveda says, “Without proper diet and lifestyle, medicines are of no use. With proper diet and lifestyle, there is no need for medicines.”
The Takeaway
Diet is a powerful tool in managing psoriasis. While research is ongoing, current evidence aligns with age-old Ayurvedic principles, emphasizing the importance of a balanced, mindful approach to eating. Small changes in diet and lifestyle can lead to significant improvements in skin health and overall well-being.
