In addition to regular exercise, a balanced diet is of course also part of a healthy lifestyle. By eating enough fresh fruit, vegetables and whole grain, as well as low-fat products of animal origin like fish, lean meat and low-fat milk, you can already do something to have a good supply of nutrients. By the way, our body digests valuable vegetable oils better than animal fats. Professional associations also recommend at least five servings of fresh fruit and vegetables per day. Even the so-called "superfoods" like goji, acerola, and many more, everybody is talking about nowadays, can be possible additions to the daily diet and do their part in preventing biofactor deficiency symptoms. For example, cheese and peanuts have a relatively high content of zinc – eating 100 g of Emmental cheese supplies 4.6 g of zinc. The recommended daily consumption lies between 7 g for women and 10 g for men. Chicken and lamb's lettuce contain a lot of folic acid – the latter a full 145 µg of it in 100 g – but it should be eaten shortly after purchase. Folic acid is destroyed very quickly when food is stored for a long time. In addition, chicken contains vitamin B6. And vitamin B12 is almost exclusively found in foods from animal origin. Those who are vegetarians or vegans can get some vitamin B12 from fermented food like sauerkraut or (alcohol-free) beer that contains the vitamin – albeit in very small quantities. Vitamin B1 is found in legumes and whole grain products; depending on storage and preparation, the vitamin content in the food can vary. Thus, eating a delicious muesli or hearty whole grain bread for breakfast could help to prevent a deficiency of this biofactor. This also supports magnesium supply – oats, in particular, contain a relatively high amount of magnesium (134 mg per 100 g), sunflower seeds even 420 mg. The recommended daily intake of magnesium for healthy adults is between 300 and 400 mg, as the German Nutrition Association indicates. A healthy lifestyle is achieved when unhealthy stimulants like alcohol and tobacco are largely eliminated. A supply with all important biofactors by a balanced lifestyle contributes to a better fitness, helps to prevent serious diseases and maintain good health.
