If healthier eating is on your list of resolutions for 2012, look no further. The January 2012 issue of the Harvard Women’s Health Watch offers 12 ways to break old dietary habits and build new ones.
For many years, nutrition research focused on the benefits and risks of single nutrients, such as cholesterol, saturated fat, and antioxidants. Today, many researchers are exploring the health effects of foods and eating patterns, acknowledging that there are many important interactions within and among nutrients in the foods we eat.
The result is a better understanding of what makes up a healthy eating plan. Here are five food- or meal-based ways to improve your diet that we list in the article (you can see all 12 on the Harvard Health website):
Pile on the vegetables and fruits. Their high fiber, mineral, and vitamin content make fruits and vegetables a critical component of any healthy diet. They’re also the source of beneficial plant chemicals not found in other foods or supplements.
Go for the good fats. Read more »

Heart disease. Stroke. Diabetes. Asthma. Osteoporosis. These common scourges are often pegged to genes, pollution, or the wear and tear caused by personal choices like a poor diet, smoking, or too little exercise. David Barker, a British physician and epidemiologist, has a different and compelling idea: these and other conditions stem from a developing baby’s environment, mainly the womb and the placenta.
Barker was the invited speaker at this year’s Stare-Hegsted Lecture, which is a big deal at the Harvard School of Public Health. In just over an hour, he covered the basics of what the British Medical Journal used to call the Barker hypothesis. It has since come to be known as the developmental origins of chronic disease. (You can watch the entire talk here.)
It goes like this: During the first thousand days of development, from conception to age 2, the body’s tissues, organs, and systems are exquisitely sensitive to conditions in their environment during various windows of time. A lack of nutrients or an overabundance of them during these windows programs a child’s development and sets the stage for health or disease. Barker and others use low body weight at term birth is a marker for poor fetal nutrition.
When a fetus is faced with a poor food supply, it Read more »

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

(Guest post submitted by MD Anderson Cancer Center)
Aisles in grocery stores and pharmacies are stacked with vitamins, minerals, herbs or other plants that you take in pill, capsule, tablet or liquid form. And, many of us buy these supplements and take them regularly, hoping to lower our chances of getting cancer and other diseases.
But do supplements really work wonders? Should you take them to help prevent cancer? Our experts say beware.
“Don’t be fooled by the label on the bottle,” says Sally Scroggs, health education manager at MD Anderson’s Cancer Prevention Center. “Researchers are still unsure about whether or not supplements actually prevent cancer.” Some studies have suggested that supplements may actually increase cancer risk by tilting the balance of nutrients in the body.

A new study in the American Journal of Obstetrics & Gynecology reports that low levels of vitamin D may be linked to early-onset preeclampsia in pregnant women.
The trial found that the average vitamin D level in 50 pregnant women with preeclampsia was 18 ng/mL, compared with 32 ng/mL in 100 women with healthy pregnancies. No casual relationship was proven, and the study’s lead author told Reuters Health that the recommended vitamin D intake in pregnant women hasn’t changed, but the study results raise yet more questions about this much-discussed nutrient.
