All JuvMed recommendations are based on scientific studies, published in science magazines and journals.
We don’t rely on “common knowledge” or other internet articles (some are disguised advertising). For example, “it is known” that fresh orange juice is good, right? Due to citric acid & high sugar content, it damages teeth. Also, it has just a fraction of the fiber contained in fruit pulp. It’s best to eat 1-2 oranges instead (and any other whole fruits), and then rinse throughly with dilluted mouthwash.
We also love good science books. For example, Life Ascending: The Ten Great Inventions of Evolution by Nick Lane explains, among others, why reducing calorie intake prolongs life in simple organisms, but might not work on mammals (studies gave contradictory results).
