💡 Smart Nutritional Guidance
Consumption advice
Add fresh jalapeño slices to tacos, salads and egg dishes; the heat wakes up your senses, increases satiety hormones and reduces the urge to load up on starch.
Best preparation methods
Remove the seeds and white inner ribs if you want less heat and more of the herby flavour, and avoid commercial canned jalapeños steeped in sugar and preservatives.
Important Nutritional Note
The capsaicin in jalapeño supports circulation and your natural energy burn; if you have a sensitive stomach or reflux, strict moderation keeps you comfortable and avoids irritation.
