A customer wrote to us: I recently bought broccoli sprouts from you, among other things, for their anti-cancer properties. Since your website generally refers to this for this type of sprout, the following information might be useful – and it's in Dutch. I found this information in the book "Foods That Fight Cancer – The Role of Nutrition in the Development of Cancer" written by two Canadian scientists, Dr. Richard Béliveau and Dr. Denis Gingras. The book is available at the library. The book is essentially one big ode to plants, such as: all cabbage varieties (Brussels sprouts, fodder cabbage, kale, broccoli, and other cruciferous vegetables), garlic, onions, tomatoes, berries, carrots, citrus fruits, etc. – and it's thoroughly scientifically substantiated, with research results and all. Among other things, I found the following texts about broccoli and broccoli sprouts: Page 86 "...broccoli sprouts, which can be found in health food stores, sometimes contain a hundred times as much sulforaphane as mature broccoli, and it would be desirable for this food to be better known and more widely consumed, for example, on bread." Page 87 "Sulforaphane also possesses antibiotic, bactericidal properties... against the bacterium that causes stomach ulcers." Page 88 "In short, the extraordinary efforts of our distant ancestors to cultivate all these cabbage varieties were certainly worthwhile. Thanks to them, we now have access to all these cruciferous vegetables with their exceptionally high content of cancer-fighting phytochemicals, particularly glucosinolates and their active forms, isothiocyanates and I3C. By including these vegetables in our daily diet, we can easily provide the body with significant amounts of these substances and thus prevent the development of various forms of cancer, especially lung, stomach, and colon cancer. We reiterate that the data currently available regarding broccoli are very encouraging. For example, if you consume a serving of broccoli three to four times a week..." "then that is demonstrably sufficient to protect you against polyps in the intestinal tract, an important stage in the development of colon cancer. And finally, the inhibitory effect of certain components of these vegetables on estrogens makes them essential components in the fight against breast cancer." Page 85 "The anti-cancer substances in cruciferous vegetables are present in a latent state in the undamaged vegetable, but eating them releases the active anti-cancer substances, which can then begin their anti-cancer work, as described later." "Therefore, you should cook cruciferous vegetables for as short a time as possible and in as little water as possible. This minimizes the loss of active myrosinase and glucosinolates dissolved in water. Cooking techniques such as steaming and stir-frying can easily be used to maximize the intake of anti-cancer substances from cruciferous vegetables." In addition, there are separate chapters on, for example, garlic, onion, grains, blueberries, and the like. In short: a wonderful – scientifically substantiated – endorsement for your products, it seems to me!
