Obesity’s Effects on Diabetic Retinopathy, Cataracts and Eye Disease

effect of obesity on eye health The obesity epidemic may have an impact on the health of the eyes. While scientific studies do not seem to have found a direct link between obesity and eye disease, maintaining a healthy weight supports your overall health and helps prevent diseases that can harm the eyes. Here’s why.

Obesity is a step up from “overweight.” The National Institute of Health (NIH) in the United States, commonly uses Body Mass Index (BMI). This is a ratio of height to weight. Overweight is a BMI of 25-29, and obesity is a BMI of 30 or more. For example, 5′ 7″ person who weighs 160 pounds would have a BMI of 25 (just barely overweight). This same person at 195 pounds would have a BMI of 30 (obese) and at serious risk of disease such as heart disease, cardio-vascular disease, stroke, cancer, diabetes and lower-body joint problems.

Age Related Macular Degeneration in Women Mitigated by Omega-Fatty Acids

Fish may prevent age related macular degeneration AMD or ARMD A research study published in Archives of Ophthalmology showed that ingesting omega-3 fatty acids and fish affects the incidence of AMD (age-related macular degeneration, or ARMD) in women. This large study (nearly 40,000 participants) over 10 years found that women who had the highest of intake of Docosahexaenoic acid (DHA, an omega-3 fatty acid) had the lowest risk of AMD versus subjects with the lowest intake. Women who ate at least one serving of fish per week had a relative risk of AMD of 0.58 compared with women who ate less than one serving per month.

This was a retrospective study that involved 39,876 female health care workers completing food frequency questionnaires. At the beginning of the study, none of them had ARMD. 265 developed age-related macular degeneration by the end of the ten-year study. Few regular fish eaters developed the disease, but the ladies who skimped on fish were significantly more likely to get AMD.

Statin Drugs and Muscle Injuries

blood test for high cholesterol statin drugs Patients taking statin drugs to lower cholesterol might be more likely to get muscle injuries, especially elderly patients.(1) Side effects and adverse reactions, according to other research, may include increased stroke risk, higher risk of Type II Diabetes, low iron, pancreatic dysfunction, sexual dysfunction, suppressed immune system, muscle pain, and more.

Be aware that increased incidence of cataracts may also be linked with statin drugs. A study(2) suggests that statin drugs are associated with an increased risk of cataracts in both men and women. In the study, cataracts risk went up within 12 months of starting statin drugs, continued while taking the drug, and dropped back to normal Continue reading “Statin Drugs and Muscle Injuries”

Strengthen Your Muscles from Your Eyes to Your Toes

exercise for the elderly including the eyes When you are in your 30’s, your skeletal muscle mass will peak. After that, they will reduce slightly in number and size every year. By the time you are in your 50’s, 15% of muscle mass may be lost, and by your 80’s, as much as 30% of muscle mass may be lost.

Obviously, strength training is crucial to strengthen your muscles and increase their size. Being strong and fit helps maintain good health and energy, reduces osteoporosis and cardiovascular disease, burns calories for weight management, improves sleep, cuts cancer risk, and much more!

Everyone should make exercise a priority throughout their lives. However, up to 75% of older Americans do not get enough exercise.(1)

It is generally recommended that older adults should do strength training two or three times per week, performing 10-15 repetitions of approximately 8 to 10 different exercises.(1)

Lupin Flour Cuts Heart Disease and Diabetes Risk

Lupins lining the roadsides are common sights for anyone who has visited Atlantic Canada or Maine during the summertime, but have you ever heard of eating lupine seeds? Even better, have you ever heard about how good lupin flour can be for the heart?

A study out of the University of Western Australia describes how it is possible to lower your risk of heart disease “significantly” by replacing conventional wholemeal flour with a blend that contains 40% lupin beans. A yearlong study of over 100 overweight men and women showed that increasing one’s intake of “lupin flour lowered blood pressure and reduced the risk of heart disease.”

Cooking with lupin flour – it is easily incorporated into the baking of bread, pasta, and cookies – is an Australian phenomenon (80% of the world’s commercial lupin crop is grown in Western Australia). A quick Google search did not yield any information about US sources, though there is some concern that the consumption of lupin flour has been linked to anaphylaxis (particularly in those with a peanut allergy).

According to this post’s source, ScienceAlert, “The study suggested that lupin flour might also be good for those suffering from Type 2 or adult onset diabetes, because even in non-diabetic individuals sensitivity to insulin improved during the trial.”

Vegetarians Less Likely to Develop Metabolic Syndrome

Metabolic syndrome, a precursor to incidences of stroke, diabetes, and heart disease is more prevalent in people who eat meat.

A new study in the journal Diabetes Care describes how vegetarians are 36% less likely to develop metabolic syndrome than meat consumers. Researchers conclude that a plant based diet can help to ward off the diseases associated with metabolic syndrome. These findings offer further proof that a healthy diet can reduce one’s chances of developing cardiovascular disease. Source: Foodconsumer.org

Eating well can also reduce your risk of developing eye diseases like cataracts and diabetic retinopathy. At Natural Eye Care we have developed The Vision Diet to help you eat your way to healthier eye sight.

Glaucoma Linked to Sleep Apnea and Circulatory Issues

A holistic perspective on health means that we recognize the interrelated nature of the body’s systems. It also means that we understand the connection between the eyes and seemingly unrelated conditions like sleep apnea and circulatory problems.

People who have sleep apnea are 75% more likely to have glaucoma than those without sleep conditions.

Glaucoma is a disease that has a lot to do with blood flow. According to an interview with professor of optometry at the University of Alabama at Birmingham, Dr. Leo Semes, people who have peripheral vascular deregulation (often signaled by chronically cold hands) might mean people are more likely to develop glaucoma.

Dr. Semes also cautions people about using beta blockers (drugs often prescribed for high blood pressure or to previous heart attack victims) because “Low blood pressure at night, coupled with high IOP in the supine position, can compromise ocular perfusion pressure.” Several population-based studies have suggested that low diastolic perfusion pressure is associated with an increased incidence of open-angle glaucoma (OAG).

Beef Recalled in Ten States Due to E. Coli Contamination

Another round of beef recalls due to potential E. coli contamination has made the news today. Over 14,000 pounds of contaminated ground beef may sit on supermarket shelves in 10 states.

The meat is available under various brand names in Arizona, California, Georgia, Indiana, Iowa, Missouri, North Carolina, Ohio, Pennsylvania, and Washington.

E. coli related infections can cause bloody diarrhea, dehydration, and, in severe cases, kidney failure and most seriously affects the very young, the very old, and those with compromised immune systems. Source: WebMD

This outbreak may cause you to think about cutting back on the meat you consume and considering the benefits of a vegetarian diet. Studies show that moving to an exclusively plant based diet can reverse atherosclerosis (hardening of the arteries), a condition that contributes directly to heart attacks.

Since this is the American Dietetic Association’s National Nutrition Month and the focus is on eating well based the color of your foods (and that means red fruits and veggies, not red meat), why not have a look at their site and think about enhancing your dietary palette (and palate!).

Napping Can Reduce Stress and Improve Heart Health

Stress is linked to a host of health problems including hypertension and the onset of glaucoma. At Natural Eye Care we recommend that people concerned about their eye health and their overall health do whatever they can to reduce their stress levels including practicing yoga or tai chi, taking up a regular meditation practice, and taking walks in nature.

A new study in International Journal of Behavioral Medicine describes how a daily nap of at least 45 minutes reduces stress and helps lower blood pressure and promotes heart health.

Research involved 85 healthy college students. Those who napped had significantly lower blood pressure than those did not sleep during the day. Source: www.healthfinder.gov

Free Radicals May Help the Heart (But Don’t Toss Your Antioxidants!)

Free radicals might be a good thing?

At Natural Eye Care, we extol the benefits of antioxidants because they fight the free radicals that lead to oxidation, which in turn cause aging: skin changes such as the appearance wrinkles, and ocular changes, including the development of cataracts and macular degeneration.

Your eyes love antioxidants like those found in bilberry (a close relative to the blueberry) and in high quality supplements.

And yet, a new study published in The Journal of Physiology (online 28 February 2011) describes how free radicals are actually essential to the healthy functioning of the heart.

It is true that high levels of free radicals can lead to heart disease, but the heart does need some quantities of free radicals to help it deal with stressful situations.

As described at Medical News Today, when under stress, the nervous system produces what are called beta-adrenergic receptors. These beta-adrenergic receptors actually produce free radicals not as a negative byproduct of metabolism (as we usually describe the process), but to make the muscles of the heart contract more strongly when necessary. The heart is then able to pump more blood throughout the body to nourish and sustain us in stressful situations.

This is not to say that you should toss out your antioxidants, but it does remind us that the body is an amazing and complex creation that rarely allows us to use a one-size-fits-all approach to disease or nutrition.
