It started with a thought: “Why compromise?”

The story of Detective No.55 began in August 2021.

Founder Yishen Tang spent years at JD.com, leading fresh food, retail, and supply chain operations. He noticed a contradiction: more and more people around him were starting to manage blood sugar and weight, but the “healthy foods” on the market were either unpalatable or nutritionally questionable. Many had to endure dry, bitter whole‑wheat biscuits or bland meal replacements – constantly torn between taste and health.

“Does healthy eating really have to be this painful?”

With that question in mind, Tang, together with co‑founder Xin Lu (former head of off‑site marketing for JD Fresh) and authoritative experts in food and nutrition, founded Detective No.55. The word “Detective” in the brand name reflects a simple principle: no shortcuts, no blind faith in labels. Every product’s GI value, nutritional content, and food safety must be human‑tested and third‑party certified – just like a detective finding the truth.

From 10 products to 30+, from online to omni‑channel

In 2022, the first low‑GI oat bran was launched. The product line quickly expanded into staples, bakery, snacks, and instant beverages, now covering over 30 SKUs. In 2024, Detective No.55 ranked No.1 in offline channel sales for low‑GI bakery products in China.

But more important than sales figures is one thing the brand has always insisted on: every low‑GI product undergoes human clinical trials in accordance with national standards and is certified by a CNCA‑authorized body. Test reports are open for inspection, and the after‑sales return rate is kept below 0.5%.

No compromise – that’s real health

Detective No.55 believes healthy eating does not require a trade‑off between taste and well‑being. Every product is developed to strike the optimal balance among low‑GI, flavor, and nutrition. This is not a marketing slogan – it is a long‑term commitment to science and quality.
