Diet and Alzheimer’s Disease: The Mediterranean Diet

3A few recent studies conducted by researchers from the neurology department at Columbia University Medical Center in New York have looked at the possible preventive effects of the typical diet eaten by people in countries around the Mediterranean sea, such as Greece. The “Mediterranean diet” is primarily made up of fruits, vegetables, and beans, fish, olive oil, a moderate amount of wine, some dairy foods, and small amounts of meat and chicken. Though more study is needed, results point to a reduced risk of developing Alzheimer’s and lower mortality rate among those who contracted the disease.

Diet and Alzheimer’s Disease: Next Steps

While there is no definitive answer to the Alzheimer’s mystery, there are certainly clues to follow. “No changes in diet, dietary supplements, food additives, vitamins, nor alternative herbal medicines have ever been demonstrated to affect the risk for Alzheimer’s disease or the course of the disease in a well-designed clinical trial experiment,” says Randolph Schiffer, MD, director of the Cleveland Clinic Lou Ruvo Center for Brain Health in Cleveland. “With that said, most of us in the Alzheimer’s research field believe that people should adopt and continue healthy lifestyles, including diets low in saturated fats and high in antioxidants and B vitamins.”

Until more research is available, it makes sense to combine a good diet with physical and mental activity and social interaction. This approach just might help keep Alzheimer’s disease, as well as other illnesses, at bay.

A Diet for Better Energy

9Juggling the responsibilities of work, life, and family can cause too little sleep, too much stress, and too little time.

Yet even when you’re at your busiest, you should never cut corners when it comes to maintaining a healthy diet. Your body needs food to function at its best and to fight the daily stress and fatigue of life.

Energy and Diet: How The Body Turns Food Into Fuel

Our energy comes from the foods we eat and the liquids we drink. The three main nutrients used for energy are carbohydrates, protein, and fats, with carbohydrates being the most important source.

Your body can also use protein and fats for energy when carbs have been depleted. When you eat, your body breaks down nutrients into smaller components and absorbs them to use as fuel. This process is known as metabolism.

Carbohydrates come in two types, simple and complex, and both are converted to sugar (glucose). “The body breaks the sugar down in the blood and the blood cells use the glucose to provide energy,” says Melissa Rifkin, RD, a registered dietitian at the Montefiore Medical Center in the Bronx, N.Y.

Energy and Diet: Best Foods for Sustained Energy

Complex carbohydrates such as high-fiber cereals, whole-grain breads and pastas, dried beans, and starchy vegetables are the best type of foods for prolonged energy because they are digested at a slow, consistent rate. “Complex carbohydrates contain fiber, which takes a longer time to digest in the body as it is absorbed slowly,” says Rifkin. Complex carbs also stabilize your body’s sugar level, which in turn causes the pancreas to produce less insulin. This gives you a feeling of satiety and you are less hungry.”

Also important in a healthy, energy-producing diet is protein (preferably chicken, turkey, pork tenderloin, and fish), legumes (lentils and beans), and a moderate amount of healthy monounsaturated and polyunsaturated fats (avocados, seeds, nuts, and certain oils).

“Adequate fluids are also essential for sustaining energy,” says Suzanne Lugerner, RN, director of clinical nutrition at the Washington Hospital Center in Washington, D.C. “Water is necessary for digestion, absorption, and the transport of nutrients for energy. Dehydration can cause a lack of energy. The average person needs to drink six to eight 8-ounce glasses of water each day.”
