I love bread, pasta, and many other foods made with wheat. Luckily, I can eat them all without having to worry about gluten. But I have to admit that the growing public awareness of gluten and the problems it can cause has got me thinking.
Gluten is an umbrella term for the proteins gliadin (in wheat), secalin (in rye), and hordein (in barley). Bakers know it as the substance that makes dough resilient and stretchy. In some people, gluten triggers an immune reaction and causes inflammation of the lining of the small intestine, which can eventually interfere with the absorption of nutrients from food. This is called celiac disease. Some of the more common symptoms of celiac disease are:
- Gas
- Bloating
- Abdominal cramps
- Diarrhea
- Foul-smelling stools
- Fatigue
- Weight loss
- Skin rash

There’s a strong association between daily servings of red meat, especially processed meat, and a nearly 20% increased risk of type 2 diabetes, researchers found.
Replacing red meat with healthier proteins, such as low-fat dairy, nuts, or whole grains, can significantly lower the risk, according to a study was published online at the American Journal of Clinical Nutrition.
Researchers reviewed questionnaire responses from 37,083 men followed for 20 years in the Health Professionals Follow-Up Study, from 79,570 women followed for 28 years in the Nurses’ Health Study I, and from 87,504 women followed for 14 years in the Nurses’ Health Study II. Diet was assessed by validated food-frequency questionnaires, and data were updated every four years. Diabetes was confirmed Read more »

The brutal heat wave gripping much of the country this week is unpleasant for healthy folks. For people with cardiovascular trouble, hazy, hot, humid days can be downright dangerous.
Your body shouldn’t get too hot (or too cold). If your temperature rises too far, the proteins that build your body and run virtually all of its chemical processes can stop working. The human body sheds extra heat in two ways, both of which stress the heart:
Radiation. Like water flowing downhill, heat naturally moves from warm areas to cooler ones. As long as the air around you is cooler than your body, you radiate heat to the air. But this transfer stops when the air temperature approaches body temperature.
Radiation requires rerouting blood flow so more of it goes to the skin. This makes the heart beat faster and pump harder. On a hot day, it may circulate two to four times as much blood each minute as it does on a cool day.
Evaporation. Read more »
