Many of us think that using insulin before it’s necessary will help to “rest” our beta cells so they’ll last longer.
But now comes a research paper showing that excess insulin actually causes diabetes in nondiabetic mice fed a chow diet. The chow diet is the normal diet given to mice unless you want to fatten them up and give them diabetes, in which case you feed them a high-fat, high-carbohydrate diet.
The high insulin levels were caused by injecting these normal mice with insulin glargine (Lantus). This injected insulin did not seem to cause hypoglycemia, although the researchers measured only fasting blood glucose (BG) levels and watched for signs of severe hypoglycemia.
The injected insulin did cause insulin resistance, as might be expected as it’s common for mammals to develop resistance to hormones whose levels are high. Most of the increased insulin resistance was in the liver. But instead of “resting” the beta cell...
Everybody does it...or at least that's what I told myself. I'd gotten away with doing it for several months: purposefully letting my blood sugars run high because I hate having lows . I'd developed this bad habit one year ago, during a summer where I was filling all of my free time with mile-long runs to the gym where I'd spend at least an hour weight lifting, taking yoga classes three times a week and jiu-jitsu classes twice a week. That all sounds dandy for a healthy diabetic, but the problem was that I was trying so hard to never go low that I was far too often running a regular 200+ blood sugar. We all know a low blood sugar in the middle of a run or a jiu-jitsu class basically puts a big RED LIGHT on the activity. My other issue was that jiu-jitsu classes were so intense that I was worried I wouldn't be able to feel the low blood sugar symptoms until it was too late, so I compensated in the most unhealthily way: a decent-sized bowl ...
Vitamin D helps the body absorb calcium, which is essential for good bone health. Vitamin D also helps the immune, muscle, and nervous systems function properly. Most vitamin D is made when an inactive form of the nutrient is activated in your skin when it's exposed to sunlight. Smaller amounts of vitamin D are in fortified milk and other foods, fatty fish, and eggs. As more and more people spend most of their time out of direct sunlight or wearing sunscreen when they are in the sun, vitamin D production from sun exposure is limited.
Research suggests that women with low levels of vitamin D have a higher risk of breast cancer. Vitamin D may play a role in controlling normal breast cell growth and may be able to stop breast cancer cells from growing.
Steps you can take
The two most reliable ways to boost your vitamin D level: get more direct sunlight exposure and take vitamin D3 supplements. Eating foods rich in vitamin D can help, but is less effective.
Sunshine exposure: Even short p...
