His secret? Cutting out processed sugar.
I can bet there are other health benefits he’s experiencing as well. More than just better cardio. I’ll bet he’s also reducing cold/flu/allergy symptoms, improving digestive health, and even noticing better skin.
Why? Because processed sugar debilitates your immune system. Cutting out sugar can improve immune health.
It seems sugar competes with vitamin C for absorption by immune cells. Too much sugar, and white blood cells are compromised. In fact, sugar can do many things to indirectly suppress immune response, including stimulating insulin release which inhibits release of growth hormones, depressing immune response. More details on the many impacts of sugar on immune health is here.
Keep up the good work, Mr. Baldwin.
