During my college years, I lived for delicious meals—Mexican, Italian, spicy Thai dishes, and especially a homemade tomato soup that my girlfriend at the time made. It was comforting and packed with flavor, but it also came with a price: terrible psoriasis flare-ups that left me miserable. I even started to think I was allergic to tomatoes.
When I sought help from my doctor and dermatologist, they assured me that diet had nothing to do with psoriasis. But I couldn’t ignore the pattern. So, I began researching on my own, and that’s when I discovered the role of nightshades—a family of plants that includes tomatoes, potatoes, eggplants, peppers, and even certain herbs like ashwagandha.
The key player in nightshades is a chemical compound called solanine. Solanine is a glycoalkaloid, a naturally occurring toxin that plants produce to defend against pests and pathogens. While it helps the plant survive, it can cause problems when ingested by humans, especially in those with autoimmune conditions.
How Solanine Affects the Body:
When consumed, The glycoalcaloyd, solanine can interfere with various physiological processes. It inhibits the activity of acetylcholinesterase, an enzyme essential for breaking down acetylcholine—a neurotransmitter involved in muscle movement, heart function, and other vital activities. By disrupting this process, solanine can lead to an accumulation of acetylcholine, which may cause overstimulation of nerve cells and result in symptoms like digestive discomfort, headaches, and muscle pain.
For those with autoimmune conditions like psoriasis, the impact can be even more pronounced. Solanine can increase intestinal permeability, often referred to as "leaky gut," allowing undigested food particles and toxins to enter the bloodstream. This triggers an immune response, leading to increased inflammation, which can manifest as skin flare-ups, joint pain, and even exacerbation of arthritis symptoms.
One of the most surprising discoveries I made was that ashwagandha, an herb commonly found in relaxation teas and supplements, is also a nightshade. While it's often recommended for stress relief, it could potentially worsen conditions like psoriasis due to its solanine content.
It’s not just the obvious foods you need to watch out for. Potato starch, for example, is a common thickening agent in many processed foods, including some brands of "clean" dressings that I once thought were safe. Without realizing it, you might be consuming nightshades that are keeping your inflammation and symptoms alive.
My Journey with Nightshades:
After eliminating nightshades from my diet, I noticed significant improvements in both my skin and joint pain. It was as if a fog had lifted, and I could finally see a path forward in managing my condition. Over time, I’ve been able to reintroduce some nightshades in moderation, and I’m now able to enjoy them occasionally without any flare-ups.
My experience taught me the importance of listening to my body and being vigilant about what I consume. Reading labels became a habit, and understanding the hidden sources of nightshades was crucial in my journey to better health.
If you’re struggling with unexplained inflammation, joint pain, or skin issues, it’s worth considering the impact of nightshades on your health. Sometimes, the foods we love can be the very thing standing in the way of our well-being.
