Are you familiar with that feeling of happiness you get when you lie on the beach in the wonderful sunshine? Or the way your mood instantly lifts on the first sunny spring day after a long, grey winter? This feeling is more than just a feeling – it is a chemical reaction. Sunlight triggers the release of serotonin in the body – a hormone that is responsible for the feelings of happiness and well-being. The sun provides not just one, but two important nutrients for human health: Happiness and vitamin D.
Vitamin D regulates the calcium and phosphate metabolism and promotes the mineralization and hardening of the bone. Vitamin D is also involved in many other metabolic processes in the body (e.g. muscle metabolism, defense against infections). A low level of vitamin D, on the other hand, is associated with diseases such as cancer, diabetes and osteoporosis.
The fat-soluble vitamin D holds a special spot among vitamins, since humands can produce it themselves through exposure to sunlight (UVB light). This form of sunshine vitamin D absorption may have worked well for our ancestors, but modern life keeps most of us chained to a desk far from the sun for almost the entire day. It is therefore almost impossible for us to get enough vitamin D from the sun alone – especially if you live far from the equator. According to a study by the German Society for Nutrition (DGE), about 60% of the German population has an insufficient vitamin D supply, according to international criteria. It also states that the intensity of sunlight in Germany is only sufficient for about 6 months of the year to ensure sufficient vitamin D formation.
Naturally, vitamin D can also be absorbed through food. However, few foods contain significant amounts of vitamin D, including fatty fish (e.g. herring and mackerel) and, to a much lesser extent, liver, margarine (fortified with vitamin D), egg yolk and some edible mushrooms. The intake via the diet with the usual foods alone is therefore also not sufficient to achieve the estimated value for an adequate intake in the absence of endogenous synthesis (home-made under solar radiation), which ensures the desired supply of at least 50 nmol/l.
To ensure a sufficient supply of vitamin D, we should therefore spend as much time as possible outside during the summer and at the same time incorporate high-quality vegan foods into our diet, as it is relatively difficult to get the vitamin through food.
It is much easier to get most of the other vitamins, minerals & trace elements essential for our body: They are all found in fresh fruit and vegetables. With a juice cure based on ultra-fresh cold-pressed fruit and vegetable juices, you will cover all vitamins and do something good for yourself in the long run.
