Immunity:
Several studies suggest that caffeine affects the bodies’ ability to absorb vitamin D. A growing body of research indicates that deficiency in vitamin D is associated with increased autoimmunity as well as an increased susceptibility to infection.
High levels of caffeine have been scientifically linked with suppressed antibody production, our bodies natural response to protect us from infection. Overall, the higher the level of caffeine, the more it interfered with vitamin D absorption. This is due to the reduced expression of vitamin D receptors on osteoblasts in the body – the cells responsible for producing bone All of that essentially means, we become more prone to catching illnesses.
Bone Health:
Vitamin D promotes calcium absorption for bone growth and remodelling and thus directly impacting the health of our bones and teeth. The negative impact of caffeine on our bodies’ ability to absorb vitamin D, in turn affects calcium absorption, and thus affects the health of our bones and teeth, gradually making them weaker.
When it comes to teeth health, we also need to be aware that caffeinated beverages like tea and coffee contain tannin which get absorbed by the porous tooth enamel resulting in staining. To the surprise of many, tea produced the highest staining!
A meta-analysis carried out in 2012, where they considered a relative risk (RR) for an increment of one cup of coffee per day found that caffeine increased the overall risk of bone fractures.
Caffeine increased the overall risk of bone fractures.
We use caffeine to give us a boost of energy during the day, but the effects of that boost can go on into the night affecting our sleeping patterns – which in turn affects our energy levels the next day – leading to, you guessed it, needing more caffeine to see us through the never-ending cycle.
Sleep plays a vital role in good health and well-being throughout our lives. During sleep, the body is working to support healthy brain function and maintaining physical health. Sleep deficiency is linked to many chronic health problems, including heart disease, kidney disease, high blood pressure, diabetes, stroke, obesity, and depression.
Keeping our caffeine intake low by swapping out a cup of coffee here and a builders tea there with a non-caffeinated drink, can benefit our health and lifestyle in a multitude of ways as demonstrated above.
