However, they also contain calcium, magnesium, iron and selenium. In addition, they consist of no less than 90% unsaturated fats. These fats provide the necessary energy and have a high nutritional value. Hazelnuts contain many unsaturated fatty acids and thus provide the necessary calories They also contain vitamin E, vitamin B, magnesium, phosphorus, iron, potassium and calcium. Wheat, this world's most famous grain, provides a lot of proteins and the important vitamins B1 and B2. Barley is probably, next to wheat, the oldest and best-known cereal. The entire barley grain is rich in minerals such as potassium, phosphorus, calcium and silicic acid. Natural bird food during the winter The bird population has changed enormously in many areas of Central Europe over the last century. This is (and is) mainly caused by humans. The diversity of wild bird species and the number of native songbirds has declined enormously, especially since 1950. This is mainly due to the loss of habitat due to: • A lot of monoculture in agriculture, without wild growth of herbs • The loss of fallow land on which many vital wild plants grow • Housing construction and road construction • The use of insecticides Just look at the number of sparrows. A few years ago, this was still one of the most common bird species in the Netherlands. Now our house sparrow is on the red list of the bird protection. Aries has therefore put together a special type of food with more flakes that is better suited to the small house sparrow.
