Preventing osteoporosis in old age should begin early. We build up our bone stores in childhood and as young adults, reaching peak bone mass in our thirties. From this peak, we begin gradually losing bone. Bones undergo a continual process called “remodeling” in which old bone is dismantled, and new bone is built to take its place. The adult human skeleton is renewed every 10 years by overhauling tiny patches of bone at a time. First, bone cells called osteoclasts chip away at old bone (often referred to as “bone resorption”); then bone cells called osteoblasts build fresh new bone. Somewhere in our thirties, we start losing more bone than we build, so the more bone we’ve amassed in our youth with good nutrition and weight-bearing exercise, the better our chances will be of maintaining strong bones for life. But, because bones are constantly being replaced, we can, in the words of President Joe Biden, “Build Back Better” at any time. Many facto…

You eat a good diet with no sugar, take your supplements and probiotics, get enough sleep, and avoid toxins, but you’re still getting colds. What gives? Well you may be neglecting a crucial factor: exercise. Exercise is critical to the proper functioning of part of your immune system, the lymphatic system. You probably haven’t given much thought to your lymphatic system. Most people don’t even know exactly what it is. The lymphatic system is a network of vessels similar to the network of veins and arteries that make up the circulatory system, however its vessels carry a fluid called lymph. Like blood, lymph delivers oxygen and nutrients to tissues and cells, but the lymph vessels function primarily as the body’s drainage system. Waste products from cells and tissues are drawn into the lymph, which the lymph vessels carry to various “lymph nodes.” Here, immune cells destroy foreign particles, including infectious organisms like bacteria and viruses as well as environmental toxi…

Is this the year you finally establish a regular exercise program? Exercise is the wonder drug par excellence. We can’t think of a single body system—whether it’s cardiovascular, digestive, neurological, musculoskeletal—you name it, that exercise doesn’t improve. It even makes the senses keener. Yet, only 20 percent of US adults meet the government’s exercise guidelines: 150 minutes a week of moderate aerobic activity (or 75 minutes of vigorous exercise, or an equivalent combination) plus two sessions per week of muscle-strengthening activity. Want a free and easy way to find out how fit you are? Click here. The most convenient and efficient way we’ve found to exercise is rebounding. What's rebounding? Simply bouncing up and down on a specially constructed trampoline called a rebounder. There is no more efficient form of exercise, bar none, because it exercises every single cell in your body simultaneously. One or two 15-minute sessions a day will provide you with…
