The body needs selenium and expects that you will provide enough of it through a healthy, balanced diet. If you don't do this, it's no big deal—you can do it the next day. If even then you don't get enough selenium, it's still not a big problem. The issue is that you cannot build up a sufficient reserve, and you can't make up for a day with too little selenium. It is very important to ensure a consistent intake.

Selenium is a powerful antioxidant that helps restore joints, fights cancer, and heart disease. Too little selenium can permanently damage the thyroid gland and the immune system. Frequent one-day illnesses are the most typical sign that your body has already been lacking selenium for several days.

But selenium is not only about thyroid problems. Mood changes are also common, as well as the occurrence of brain fog (you notice this if you frequently can’t remember things), sudden anxiety, fatigue, muscle weakness, acne, pimples in places where you haven’t had them before, dry skin, and many other issues. Selenium deficiency is extremely difficult to detect in time. We only pay attention to it when it's (too) late.

To avoid all these issues, you should eat a handful of nuts per day, and one egg for every 50 kilograms of your body weight (for example, if you weigh 70 kilograms, you should eat 2 eggs per day!). It is also beneficial to eat a handful of sunflower seeds or as much tuna as you weigh in kilograms.

Finally, one more thing: selenium requirements increase with age, and in general, you should consume twice as many micrograms as your age in years. The minimum daily amount is 30 to 50 micrograms; however, since we get selenium from foods that absorb it from the soil, and the soil in Europe (as well as in China!) is increasingly depleted, we often need to use dietary supplements or consume a more varied diet.

The latter is becoming more and more difficult, isn’t it?!
