Most foods contain some calcium, especially bone broth, small fish whole, fish eggs, good quality long-ripened cheeses, meats, as well as certain seeds and nuts. If we eat these regularly, there is no need to supplement calcium. Excessive intake of calcium and simultaneous deficiencies of magnesium, vitamin K, vitamin D3 and vitamin A can lead to the calcification of soft tissues.

Cook the turnips in boiling salted water for 10 minutes. Remove with a straining spoon, then cook the broccoli in the same water for 5 minutes and drain. In a food processor, pulse the turnips and broccoli, remove them into a mixing bowl, add the grated zucchini, ham, egg yolks, 30 g grated cheese, salt and pepper and mix well. Whisk the egg whites with a pinch of salt until stiff and gently fold into the other ingredients. Grease the muffin tins with oil, scoop the batter into the tins, sprinkle a little cheese over each one and bake in a preheated oven at 190°C for about 20 minutes. Allow to cool completely before removing from the tins. A great option for breakfast, in a lunchbox or on a hike.
