Are you an “Apple” or a “Pear?” If you have the “Apple Shape,” You May Have a Higher Risk for Dementia
Having a “pear” or “apple” shape can determine the health of a woman’s body – and mind. Of course, Eve knew all about the troubles an apple could bring.
If you gain weight in your chest and belly, you have an apple shape. If your weight gain is in your hips and thighs, you’re a pear. Studies have long shown that if your body fat is concentrated primarily in the middle – like an apple, it is more biologically active and is correlated with health problems like heart disease, high blood pressure, diabetes and cancer.
This study, published in the Journal of the American Geriatrics Society found that as body weight increased in post-menopausal women, cognitive function decreased. But the worst cognitive decline occurred when high body weight was coupled with an apple shape compared to the pear shaped body fat distribution.
This troubling result seems to coincide with studies showing a higher risk of dementia in people with high blood pressure, heart disease or diabetes, the risk of which is heightened by having the apple-shaped body fat distribution.
If you’re overweight, you may still be healthy, as long as you’re physically active and eat healthfully. But if your excess weight is carried mostly around the middle, it would be wise to keep track of your health, especially your blood pressure, blood glucose and cholesterol, and lose weight so that your waist circumference* measures 35″ or less, which is what health authorities recommend for women (40″ or less for men).
*Your accurate waist circumference is measured at the level of your belly button (not the smallest part of your middle).

People are always asking me if fruit is too high in sugar to eat, especially if you have diabetes. This fear of fruit, I believe, is leftover from the Atkins craze, making foods like fruits, and even vegetables like carrots, verboten. This is one of the most tragic consequences of this diet fad, because avoiding fruit can actually damage your health.
People who eat fruit have a lower incidence of Type 2 Diabetes, the most common form of the disease, according to a recently published Harvard study. But this study isn’t alone in its conclusions. It corroborates decades of research showing the nutritional value and health benefits of fruits.
Fruit is high in water content and fiber, which help you feel full with fewer calories. Even though it contains simple sugars and carbohydrates, most fruits have a relatively low glycemic index, that is, when you eat it, your blood sugar raises only moderately, especially when compared with refined sugar or flour products.
Fruit is loaded with nutrients scientists believe protect people from major chronic diseases such as heart disease, cancer, type 2 diabetes, and more. The potassium in fruit helps lower blood pressure and actually helps neutralize the blood pressure-raising affects of sodium.
Eating more fruits and vegetables – as high as 5 cups per day or more – is a habit which could help you stabilize and even reverse Type 2 Diabetes. Yes, it is possible!
And, the best part of fruit? It’s delicious! It’s easy to eat, to pack in your lunch box for the office or school, and it’s such a refreshing snack or dessert. What could be better?

Supported by NIH grant from the National Heart, Lung, and Blood Institute.
Background: Data from mechanistic studies support a beneficial effect of specific flavonoids on insulin sensitivity. However, few studies have evaluated the relation between intakes of different flavonoid subclasses and type 2 diabetes.
Objective: The objective was to evaluate whether dietary intakes of major flavonoid subclasses (ie, flavonols, flavones, flavanones, flavan-3-ols, and anthocyanins) are associated with the risk of type 2 diabetes in US adults.
Design: We followed up a total of 70,359 women in the Nurses’ Health Study, 89,201 women in the NHS II, and 41,334 men in the Health Professionals Follow-Up Study who were free of diabetes, cardiovascular disease, and cancer at baseline.
Results: During 3,645,585 person-years of follow-up, we documented 12,611 incident cases of type 2 diabetes. Higher intakes of anthocyanins were significantly associated with a lower risk of type 2 diabetes after multivariate adjustment for age, BMI, and lifestyle and dietary factors. Consumption of anthocyanin-rich foods, particularly blueberries and apples/pears, was also associated with a lower risk of type 2 diabetes. No significant associations were found for total flavonoid intake or other flavonoid subclasses.
Conclusion: A higher consumption of anthocyanins and anthocyanin-rich fruit was associated with a lower risk of type 2 diabetes.

Our grandmothers have been extolling the virtues of “roughage” for generations. Turns out, they were right. But the benefits of roughage, aka fiber, are far more vast than grandmother ever realized.
High fiber diets have been shown to reduce the occurrence of several chronic diseases. Because of this, in 2002 the expert scientists on the National Academy of Sciences’ Food and Nutrition Board, the group which issues periodic dietary recommendations for Americans, for the first time recommended Americans double their daily fiber intake to 38 grams for men and 25 grams for women. That’s the level they found is protective against heart disease.
Fiber is mainly carbohydrate, the undigestible part of plant foods (fruits, vegetables, whole grains, legumes, and nuts)– it travels unchanged through the intestines. Fiber comes in many different forms in food. It is concentrated, for instance, in the skin of fruits and vegetables, such as apples, corn, and legumes, the seeds of vegetables and fruits such as berries and cucumbers, and the germ and bran or coating which surrounds wheat kernels and other grains. These essential parts of the grain are removed to create white flour and other refined grains.
Americans eat very little fiber – half of what is recommended, eating a highly refined diet, instead. And if you’re on a low carb diet, you’re lucky to be eating any. There are plenty of great reasons to increase your intake of fiber. My clients who do discover multiple benefits.
Easier Weight Loss
Not eating enough fiber may be one reason why people are getting fatter.
A study published in the American Journal of Clinical Nutrition last year found that women with the highest fiber intake had a 49 percent lower risk of major weight gain compared with women eating less fiber.
High fiber diets are usually lower in calories. Though fiber is mainly carbohydrate, very little of it, if any, is actually digested. So, with foods high in fiber, you’re actually eating food which only partially counts as calories (and you thought that was only in your dreams!).
High fiber foods are also bulky, and often watery foods, which means they fill you up for fewer calories. Studies have shown adding high fiber foods, such as vegetables, before or during a meal decreases the overall calorie content of the meal by about 100. While saving 100 calories a day may not sound like much, it translates into losing ten pounds in one year.
Another factor which helps you feel satisfied with fewer calories is the “chew” factor, High fiber foods require more chewing and take longer to eat, which leads to more physical and psychological satisfaction with your meals.
Improve Intestinal Function
Digestive disorders are on the rise and a main reason may be the dearth of fiber in our diets. For most digestive disorders such as reflux disease, constipation, diarrhea, hemmorhoids, diverticulitis, ulcerative colitis, Crohn’s disease and irritable bowel syndrome, a higher fiber diet relieves symptoms and can even prevent the disorder in the first place.
Many people with these disorders, particularly Crohn’s disease or diarrhea, think they should avoid fiber, but that’s a mistake for most. Fiber increases bulk and motility and this relieves pressure, keeps everything regular and more comfortable for the whole gammit of intestinal disorders.
Imagine fiber as a dry sponge in your intestinal tract. Fiber pulls water into the system, keeping everything larger, softer and moving more quickly and easily.
Lower Diabetes Risk
Numerous studies have shown that high fiber diets improve diabetes control and may even prevent diabetes. In fact, it’s been estimated that fiber, especially cereal fiber from whole grains, reduces diabetes risk by about 35 percent.
There are several theories explaining why this may be true. First, high fiber foods tend to have a lower glycemic index. This means that after eating, blood sugar levels rise less (diabetes is characterized by high blood sugar). And studies confirm that people eating high fiber diets usually have lower fasting insulin levels, an indicator of overall lower blood sugar levels.
Also, high fiber foods contain many nutrients which may improve diabetes. For one, magnesium, a nutrient found in whole grains, legumes, tofu and some vegetables, improves insulin resistance, a cause of Diabetes Type II, the most prevalent type of diabetes. Vitamin E, found in whole grains and nuts, may also improve insulin resistance.
Prevent Heart Disease
Fiber helps prevent heart disease in a variety of ways. Lower circulating insulin caused by a high fiber diet reduces heart disease risk and heart attacks. Also, research shows viscous fiber found in legumes, oats, rye, barley and some fruits and vegetables, reduces LDL cholesterol (the bad kind which correlates with heart attack). In fact, it has been estimated by the NAS expert panel that for every gram of soluble fiber you eat, you’ll reduce heart disease risk by 2.4 percent.
High fiber diets reduce triglycerides, or blood fat, another heart disease risk factor. New evidence shows fiber intake is linked to lower C-reactive protein, an indicator of inflammation, which is an emerging heart disease risk factor.
Whole grains and some legumes contain many beneficial healthful substances, including phytoestrogens, which affect circulating hormone levels and may impact heart disease positively. Diets high in fruits and vegetables, containing high levels of the nutrient potassium, also significantly lower blood pressure and stroke.
High fiber foods such as dark green vegetables, legumes and fortified cereals contain the nutrient, Folate (or folic acid). Researchers have found that low blood levels of folate are linked to heart disease.
Reduce Cancer Risk
In populations eating low dietary fiber, doubling fiber intake from foods could reduce the risk of colorectal cancer by forty percent, according to recent findings in the EPIC study (European Prospective Investigation into Cancer and Nutrition), an on-going study of 500,000 people in 10 European countries.
In fact, the majority of studies suggest that dietary fiber is protective against colon cancer, according to the NAS expert panel’s report on fiber. But, a few important studies have not found a link so the issue remains to be resolved, concluded the report.
Several mechanisms have been proposed for this beneficial effect. First, because it pulls water into the intestinal tract, fiber dilutes carcinogens and other tumor-promoters, and causes a more rapid transit, thus causing less exposure of your body to potentially damaging substances. Fiber also causes other beneficial chemical reactions, such as lowering the ph. And lower insulin levels caused by high fiber diets are correlated with lower colon cancer risk. The EPIC researchers stressed that foods supplying fiber also contribute many other nutrients and phytochemcials (beneficial plant chemicals) that have been linked to cancer protection, according to the study reported in The Lancet last year.
Reasons given for some disappointing results connecting fiber to cancer prevention are that the benefits of dietary fiber may not occur until fiber intake is sufficiently high, and Americans eat very low levels, compared with Europeans, so it’s hard for scientists to measure an effect in American diets. Also, some studies tested fiber supplements, as opposed to fiber in food, and researchers say that’s a completely different animal.
Human studies specifically looking at fiber supplements haven’t shown good results and did not find a lower incidence of colon polyps, a precursor to colon cancer. In fact animal studies suggest fiber supplements might increase cell proliferation, which suggests a negative effect, increasing one’s risk of developing cancer rather than reducing the risk.
Scientists believe that fiber supplements will probably not produce most of the health benefits found with high fiber foods (regardless of what the commercials on TV say), except for improved gastrointestinal function and slightly lower LDL, if the supplement is made from viscous fibers such as guar gum or psyllium. But fiber supplements’ role in chronic disease prevention remains unproven. It’s best to get fiber from whole foods in your diet.
Adding Fiber To Your Diet
The key to adding fiber while preventing gas or cramps sometimes associated with increased fiber intake, is eating fiber consistently, adding it slowly, and drinking plenty of fluids. If you eat a low fiber diet and suddenly at a party scarf down a large bowl of baked beans, you may suffer negative side effects. To prevent this, Leslie Bonci, author of “The American Dietetic Association Guide to Better Digestion,” recommends adding fiber by just five gram increments each week until you get to the recommended daily intake of 25 grams for women and 38 grams for men. Then, it’s important that you consistently eat regular amounts of fiber throughout each day.
