When you enroll in a free nutrition course on Udemy, you are not the customer. The instructor is the customer (buying your review). Udemy is the merchant (taking a 75% cut of future sales). And you? You are the raw material—the data point, the email address, the 5-star review that unlocks the algorithm.

If you truly want to understand nutrition, do not look for a free course. Look for a free textbook, a university audit, or a public library card. The information is free. The curation is what costs money. And on Udemy, the curation is exactly what you pay for.
