Drinking 100 percent fruit juice does not affect blood sugar levels – Study

I know that a lot of people have strong feelings about juices – both positive and negative. I am kind of agnostic. I like pineapple-orange juice and drink it regularly. Otherwise, I am not much into fruit juice.

Juice found to have no association with major diabetes risk factors

One hundred percent juice does not have a significant effect on fasting blood glucose, fasting blood insulin, or insulin resistance according to a new study published in the Journal of Nutritional Science. The findings are consistent with previous research indicating that 100% fruit juice is not associated with an increased risk of developing Type 2 Diabetes and support a growing body of evidence that 100% fruit juice has no significant effect on glycemic control.

A comprehensive data analysis quantitatively assessed the relationship between drinking 100% juice and blood glucose control. Using fasting blood glucose and fasting blood insulin levels as biomarkers for diabetes risk, the systematic review and meta-analysis included 18 randomized controlled trials (RCT) to evaluate the impact of 100% juice from fruits, such as apple, berry, citrus, grape, and pomegranate.

According to The American Diabetes Association, about 90% of the 29 million cases of diabetes in adults and children in the United States are considered Type 2. Type 2 Diabetes is a metabolic disorder where the body is unable to respond to insulin. The first line of defense for preventing and treating Type 2 Diabetes is following a healthy lifestyle. Eating right, exercising regularly and staying at a healthy weight are encouraged. U.S. Dietary Guidelines recommend consumption of a healthy eating pattern which includes fruits, vegetables, grains, low-fat or fat-free dairy and a variety of protein foods. A 4-oz. glass of 100 percent juice counts as one serving (1/2 cup) of fruit, and can complement whole fruit to help individuals add more produce to their diets. (my emphasis)

Current trends point to more than half of U.S. children suffering from obesity as adults – Harvard

If current trends in child obesity continue, more than 57 percent of today’s children in the U.S. will have obesity at age 35, according to a new study from Harvard T.H. Chan School of Public Health.

The study also found that excess weight in childhood is predictive of adult obesity, even among young children, and that only children currently at a healthy weight have less than a 50 percent chance of having obesity as adults. The findings were based on a rigorous simulation model that provides the most accurate predictions to date of obesity prevalence at various ages.

The study was published in the November 30, 2017 issue of the New England Journal of Medicine.

“Adult obesity is linked with increased risk of diseases such as diabetes, heart disease, and cancer,” said Zachary Ward, programmer/analyst at Harvard Chan School’s Center for Health Decision Science and lead author of the study. “Our findings highlight the importance of prevention efforts for all children as they grow up, and of providing early interventions for children with obesity to minimize their risk of serious illness in the future.” (my emphasis) Continue reading

Obesity is common, serious and costly – CDC

I have written about the dangers of obesity almost more times than I can remember, yet it remains a nightmare for us. As we tell our children over and over – actions have consequences. When will we learn that everything we eat and drink becomes a part of us. We don’t just get to enjoy the taste with no physical effects afterwards.

    • More than one-third (36.5%) of U.S. adults have obesity. [Read CDC National Center for Health Statistics (NCHS) data brief PDF-704KB]
    • Obesity-related conditions include heart disease, stroke, type 2 diabetes and certain types of cancer, some of the leading causes of preventable death. [Read guidelines]
    • The estimated annual medical cost of obesity in the U.S. was $147 billion in 2008 U.S. dollars; the medical costs for people who have obesity were $1,429 higher than those of normal weight. [Read summary]

Losing weight through diet and exercise helps brain blood circulation in older diabetics – Study

Once again we have it demonstrated that diet and exercise prove beneficial even to seniors suffering from diabetes, according to HealthyinAging.org.

Type 2 diabetes affects blood circulation. The disease stiffens blood vessels and reduces the amount of oxygen that circulates throughout your body. This includes your brain. When blood flow in the brain is impaired, it can affect the way we think and make decisions.

old-people-dancing

People who have type 2 diabetes are often overweight or obese. These are conditions that may also be linked to cognitive problems (problems with thinking abilities). Lowering calorie intake and increasing physical activity are known to reduce the negative effects of type 2 diabetes on the body. However, the effects of these interventions on cognition and the brain are not clear.

Recently, researchers examined information from a 10-year-long study called Action for Health in Diabetes (Look AHEAD). In this study, participants learned how to adopt healthy, long-term behavior changes. In their new study, the researchers focused on whether participants with type 2 diabetes who lowered calories in their diet and increased physical activity had better blood flow to the brain. The researchers published their findings in the Journal of the American Geriatrics Society. Continue reading

Plant-based diet yields cardiometabolic health benefits -MNT

I was a vegetarian in my younger days. I lasted for about five years. In those days, there wasn’t the same level of consciousness or acceptance of this kind of diet that there is now. Although I left vegetarianism, I have continued to limit the amount of red meat I consume. I also eat a lot of fish and seeds and nuts for protein sources.

Medical News Today reports that plant-based eating patterns continue to soar in popularity and a group of nutrition researchers outline the science behind this sustainable trend in a review paper, entitled “Cardiometabolic benefits of plant-based diets,” which appears as an online advance in Nutrients. The review will publish in a future special edition, entitled “The Science of Vegetarian Nutrition and Health.”

chinese-vegetarian-food

The review outlines how a plant-based diet, which is naturally low in calories, saturated fat, and cholesterol, and rich in nutrients, like fiber and antioxidants, could be one tool, in addition to adopting a healthful lifestyle, used to improve nutrition intake and reduce the risk of heart disease, stroke, obesity, and type 2 diabetes.

 

The authors, Hana Kahleova, M.D., Ph.D., Susan Levin, M.S., R.D., C.S.S.D., and Neal Barnard, M.D., F.A.C.C., analyzed clinical research studies and reviews published until May 2017. Their research finds a plant-based diet, built around vegetables, fruits, whole grains, and legumes, can improve nutrient intake and help manage body weight and glycemic control, improve cholesterol, lower blood pressure, and reverse atherosclerosis, or the narrowing of the arteries caused by the accumulation of arterial plaque.

“The future of health care starts on our plates,” says Dr. Kahleova, the lead study author and the director of clinical research at the nonprofit Physicians Committee. “The science clearly shows food is medicine, which is a powerful message for physicians to pass on to their patients and for policymakers to consider as they propose modifications for health care reform and discuss potential amendment to the 2018 Farm Bill.”

To understand the health benefits of a plant-based diet, the researchers analyze its structure:

Fiber

Fiber contributes to bulk in the diet without adding digestible calories, thus leading to satiety and weight loss. Additionally, soluble fiber binds with bile acids in the small intestines, which helps reduce cholesterol and stabilize blood sugar.

Plant-Based Rx: Aim to eat at least 35 grams of dietary fiber a day. The average American consumes 16 grams of dietary fiber each day.

Fats

Plant-based diets are lower in saturated fat and dietary cholesterol. Replacing saturated fats with polyunsaturated and monounsaturated fats can increase insulin sensitivity, a risk factor for metabolic syndrome and type 2 diabetes.

Plant-Based Rx: Swap meat and dairy products, oils, and high-fat processed foods for smaller portions of plant staples, like a few avocado slices or a small handful of nuts and seeds, which are rich in polyunsaturated and monounsaturated fats.

Plant Protein

Vegetable proteins reduce the concentrations of blood lipids, reduce the risk of obesity and cardiovascular disease, and may have anti-inflammatory and anti-cancer effects.

Plant-Based Rx: Legumes, or lentils, beans, and peas, are naturally rich in protein and fiber. Try topping leafy green salads with lentils, black beans, edamame, or chickpeas.

Plant Sterols

Plant sterols that have a structure similar to that of cholesterol reduce cardiovascular disease risk and mortality, have anti-inflammatory effects, and positively affect coagulation, platelet function and endothelial function, which helps reduce blood clots, increases blood flow, and stabilizes glycemic control in patients with type 2 diabetes.

Plant-Based Rx: Consume a high intake of antioxidants and micronutrients, including plant sterols, from whole plant foods, like vegetables, fruits, grains, nuts, beans, and seeds. A plant-based diet supports cardio-metabolic benefits through several independent mechanisms. The synergistic effect of whole plant foods may be greater than a mere additional effect of eating isolated nutrients.

“To make significant health changes, we have to make significant diet changes,” concludes Dr. Kahleova. “A colorful plant-based diet works well for anyone, whether you’re an athlete looking to boost energy, performance, and recovery by enabling a higher efficiency of blood flow, which equates to oxygen conversion, or if you’re a physician who wants to help patients lose extra weight, lower blood pressure, and improve their cholesterol.”

Dr. Kahleova and the study authors recommend using a plant-based diet as an effective tool to treat and prevent cardiometaoblic disease, which they would like to see promoted through future dietary guidelines and nutrition policy recommendations.

Are sugary drink interventions cutting consumption?

I have written repeatedly about the ill effects of soft drinks, both sugary and diet, on our bodies. You can check out my Page – What’s wrong with soft drinks? for chapter and verse. So this item in Medical News Today citing efforts to curb sugary drink consumption caught my eye.

An evaluation of efforts designed to reduce how many sugary drinks we consume shows some success in changing younger people’s habits but warns they cannot be the only way to cut consumption.

sugar

Nutritionists at the University of Leeds have carried out the first comprehensive review of interventions to reduce sugary drinks consumption. The team analyzed 40 studies with 16,500 participants across three age groups: children, teenagers and adults.

Their study, published in the Obesity Reviews journal, found that children participating in these programs reduced their sugary drink intake by around 30%, removing nearly 2.5 teaspoons of sugar from a child’s average intake of 16 teaspoons per day.

Interventions aimed at teenagers saw sugary drink consumption reduced by nearly 10%. However, there was almost no measurable change in adults participating in these programs. Continue reading

Beware of blue light at night – Harvard

Sleep, like walking, is one of the critical elements of good health very commonly not appreciated by the man on the street. I have a Page – How important is a good night’s sleep with a ton of information on it.

Here is some valuable info from the Harvard Health Letter on getting a good night’s sleep.

by-lemat-works

Until the advent of artificial lighting, the sun was the major source of lighting, and people spent their evenings in (relative) darkness. Now, in much of the world, evenings are illuminated, and we take our easy access to all those lumens pretty much for granted.

But we may be paying a price for basking in all that light. At night, light throws the body’s biological clock—the circadian rhythm—out of whack. Sleep suffers. Worse, research shows that it may contribute to the causation of cancer, diabetes, heart disease, and obesity. (My emphasis)

But not all colors of light have the same effect. Blue wavelengths—which are beneficial during daylight hours because they boost attention, reaction times, and mood—seem to be the most disruptive at night. And the proliferation of electronics with screens, as well as energy-efficient lighting, is increasing our exposure to blue wavelengths, especially after sundown.

Daily rhythms influenced by light

Everyone has slightly different circadian rhythms, but the average length is 24 and one-quarter hours. The circadian rhythm of people who stay up late is slightly longer, while the rhythms of earlier birds fall short of 24 hours. Dr. Charles Czeisler of Harvard Medical School showed, in 1981, that daylight keeps a person’s internal clock aligned with the environment.

The health risks of nighttime light

Study after study has linked working the night shift and exposure to light at night to several types of cancer (breast, prostate), diabetes, heart disease, and obesity. It’s not exactly clear why nighttime light exposure seems to be so bad for us. But we do know that exposure to light suppresses the secretion of melatonin, a hormone that influences circadian rhythms, and there’s some experimental evidence (it’s very preliminary) that lower melatonin levels might explain the association with cancer.

A Harvard study shed a little bit of light on the possible connection to diabetes and possibly obesity. The researchers put 10 people on a schedule that gradually shifted the timing of their circadian rhythms. Their blood sugar levels increased, throwing them into a prediabetic state, and levels of leptin, a hormone that leaves people feeling full after a meal, went down.

Even dim light can interfere with a person’s circadian rhythm and melatonin secretion. A mere eight lux—a level of brightness exceeded by most table lamps and about twice that of a night light—has an effect, notes Stephen Lockley, a Harvard sleep researcher. Light at night is part of the reason so many people don’t get enough sleep, says Lockley, and researchers have linked short sleep to increased risk for depression, as well as diabetes and cardiovascular problems.

The power of the blues

While light of any kind can suppress the secretion of melatonin, blue light at night does so more powerfully. Harvard researchers and their colleagues conducted an experiment comparing the effects of 6.5 hours of exposure to blue light to exposure to green light of comparable brightness. The blue light suppressed melatonin for about twice as long as the green light and shifted circadian rhythms by twice as much (3 hours vs. 1.5 hours).

In another study of blue light, researchers at the University of Toronto compared the melatonin levels of people exposed to bright indoor light who were wearing blue-light–blocking goggles to people exposed to regular dim light without wearing goggles. The fact that the levels of the hormone were about the same in the two groups strengthens the hypothesis that blue light is a potent suppressor of melatonin. It also suggests that shift workers and night owls could perhaps protect themselves if they wore eyewear that blocks blue light. Inexpensive sunglasses with orange-tinted lenses block blue light, but they also block other colors, so they’re not suitable for use indoors at night. Glasses that block out only blue light can cost up to $80.

Less-blue light

If blue light does have adverse health effects, then environmental concerns, and the quest for energy-efficient lighting, could be at odds with personal health. Those curlicue compact fluorescent lightbulbs and LED lights are much more energy-efficient than the old-fashioned incandescent lightbulbs we grew up with. But they also tend to produce more blue light.

The physics of fluorescent lights can’t be changed, but coatings inside the bulbs can be so they produce a warmer, less blue light. LED lights are more efficient than fluorescent lights, but they also produce a fair amount of light in the blue spectrum. Richard Hansler, a light researcher at John Carroll University in Cleveland, notes that ordinary incandescent lights also produce some blue light, although less than most fluorescent lightbulbs.

What you can do

  • Use dim red lights for night lights. Red light has the least power to shift circadian rhythm and suppress melatonin.
  • Avoid looking at bright screens beginning two to three hours before bed.
  • If you work a night shift or use a lot of electronic devices at night, consider wearing blue-blocking glasses or installing an app that filters the blue/green wavelength at night.
  • Expose yourself to lots of bright light during the day, which will boost your ability to sleep at night, as well as your mood and alertness during daylight.When I work on my computer late at night, I always wear a pair of blue blocker sunglasses. You can buy them on Amazon for under $20. I have no problems getting to sleep.

Cut diabetes risk by eating legumes – Study

I just wrote about how nuts improve cholesterol levels  three days ago.

Now comes a new study from overseas telling us how good legumes are for our bodies.

What-Are-Legumes.jpg

Recent results from the PREDIMED (Prevención con Dieta Mediterranea) study show a protective association between total legumes consumption, especially lentils, and the risk of developing subsequent type 2 diabetes after more than 4 years of follow-up of 3349 participants at high cardiovascular risk. Moreover, the present study shows that replacing a half a serving/day of eggs, bread, rice or baked potato with a  half a serving/day of legumes was also associated with a lower risk of type 2 diabetes.

Legumes are a food group rich in B vitamins, contain different beneficial minerals (calcium, potassium and magnesium) and sizeable amounts of fibre and are regarded as a low-glycemic index food, which means that blood glucose levels increase only slowly after consumption. Due to these unique nutritional qualities, eating legumes regularly can help improve human health. In fact, the Food and Agriculture Organization of the United Nations (FAO) declared 2016 as the international year of legumes to raise people’s awareness of their nutritional benefits.

Fructose is generated in the human brain

Fructose, a form of sugar linked to obesity and diabetes, is converted in the human brain from glucose, according to a new Yale study. The finding raises questions about fructose’s effects on the brain and eating behavior.

The study was published on Feb. 23 by JCI Insight.

Fructose is a simple sugar found in fruits, vegetables, table sugar, and many processed foods. Excess consumption of fructose contributes to high blood sugar and chronic diseases like obesity. The Yale research team had demonstrated in a prior study that fructose and another simple sugar, glucose, had different effects on brain activity. But it was not known whether fructose was produced in the brain or crossed over from the bloodstream.

 

brain-sleep-wake-neurosciencenews-public

To investigate, the research team gave eight healthy, lean individuals infusions of glucose over a four-hour period. They measured sugar concentrations in the brains of the study participants using magnetic resonance spectroscopy, a noninvasive neuroimaging technique. Sugar concentrations in the blood were also assessed.

DIABETES is a DISEASE most people simply view as a “CONDITION.” It is certainly not FEARED like CANCER. This misconception is based on the belief that diabetes is CONTROLLED with prescription medication. This has proven to be an UNRELIABLE approach to addressing the underlying mechanisms of this disease and entirely incapable at reversing it LONG […]

Even mildly excessive body iron stores increase the risk of type 2 diabetes – Study

Diabetes was the seventh leading cause of death in the United States in 2010 based on the 69,071 death certificates in which diabetes was listed as the underlying cause of death. In 2010, diabetes was mentioned as a cause of death in a total of 234,051 certificates, according to the latest information from the American Diabetes Association.

In addition,  Diabetes may be under-reported as a cause of death. Studies have found that only about 35 percent to 40 percent of people with diabetes who died had diabetes listed anywhere on the death certificate and about 10 percent to 15 percent had it listed as the underlying cause of death.

Diabetes-4.jpg

Even mildly elevated body iron contributes to the prevalence and incidence of type 2 diabetes, according to research from the University of Eastern Finland. Excess body iron accumulation is a known risk factor of Type 2 diabetes in hereditary hemochromatosis, but the results presented by Dr Alex O. Aregbesola in his doctoral thesis show that elevated iron is a risk factor in the general population as well, already at high levels within the normal range.

Men accumulate more iron and are more at risk Continue reading

Study supports lower cut-off point for defining prediabetes

At the risk of being a wet blanket on Thanksgiving Day, this seems an appropriate topic.

Let’s face it the majority of us are bad eaters. Some 60 percent of us are overweight and half of them outright obese. Additionally, we are seeing adult onset diabetes occurring in teenagers. We need to start eating better and exercising more.

The health risks and mortality associated with prediabetes seem to increase at the lower cut-off point for blood sugar levels recommended by some guidelines, finds a large study published in The BMJ today.

does-being-a-diabetic-affect-my-chances-to-conceive.png

Prediabetes is a “pre-diagnosis” of diabetes — when a person’s blood glucose level is higher than normal, but not high enough to be considered diabetes. If left untreated, prediabetes can develop into type 2 diabetes. An estimated 79 million people in the US and 7 million people in the UK are thought to be affected. Continue reading

Chemical Exposure Linked to Lower Vitamin D Levels – Study

Vitamin D has been called the rock star of vitamins. For an idea about all the good things our bodies get from vitamin D, check out these posts: How good is Vitamin D for you? Infographic, Vitamin D and your body – Harvard.

Exposure to bisphenol A (BPA) and other endocrine-disrupting chemicals (EDCs) may reduce levels of vitamin D in the bloodstream, according to a new study published in the Endocrine Society’s Journal of Clinical Endocrinology & Metabolism.

bpa-free-plastic.jpg

The study is the first to find an association between EDC exposure and vitamin D levels in a large group of U.S. adults. EDCs are chemicals or mixtures of chemicals that can cause adverse health effects by interfering with hormones in the body. The Society’s Scientific Statement on EDCs examined more than 1,300 studies that found links between chemical exposure and health problems, including infertility, obesity, diabetes, neurological problems and hormone-related cancers.

Sitting too long may raise heart disease risk – AHA

In December 2013 I posted for the first time on the dangers of sitting too long. “I must confess I was amazed to learn that simply sitting for long periods could be as the headline says, “Hazardous to Your Health and Longevity.” So, it’s not enough to exercise regularly, you also need to make sure that you don’t sit immobile for long periods….” That was the first sentence in the post Too much sitting can be hazardous to your health and longevity.

Now comes the American Heart Association saying, “Being sedentary is not just a lack of exercise, it is a potentially independent risk factor for heart disease and stroke.

“Regardless of how much physical activity someone gets, prolonged sedentary time could negatively impact the health of your heart and blood vessels,” said Deborah Rohm Young, Ph.D., director of behavioral research at Kaiser Permanente Southern California in Pasadena and chair of the new scientific statement published in the American Heart Association journal Circulation.

“According to the statement, sedentary behavior may be associated with an increased risk of developing diabetes, cardiovascular disease, impaired insulin sensitivity (linked to diabetes) and an overall higher risk of death from any cause. (my emphasis)

Chronic diseases and us – Infographic

I ran across this infographic in my meanderings and thought it had a lot of interesting if depressing information, like the increase in diabetes in the last few decades. On the positive side, “Many chronic diseases have a root in lifestyle decisions, from obesity to smoking. And, many of these conditions can be treated or even prevented by changing behavior.”

7 things you can do to prevent a stroke – Harvard

Regardless of your age or family history, a stroke doesn’t have to be inevitable. Here are some ways to protect yourself starting today, Harvard Health Publications said.

But , what is a stroke?

A stroke is a “brain attack.”  It can happen to anyone at any time. It occurs when blood flow to an area of brain is cut off. When this happens, brain cells are deprived of oxygen and begin to die. When brain cells die during a stroke, abilities controlled by that area of the brain such as memory and muscle control are lost, according to the National Stroke Association.

Stroke by the Numbers
•    Each year nearly 800,000 people experience a new or recurrent stroke.
    •    A stroke happens every 40 seconds.
    •    Stroke is the fifth leading cause of death in the U.S.
    •    Every 4 minutes someone dies from stroke.
    •    Up to 80 percent of strokes can be prevented.
    •    Stroke is the leading cause of adult disability in the U.S.

Age makes us more susceptible to having a stroke, as does having a mother, father, or other close relative who has had a stroke.

ucm_452104.jpg

You can’t reverse the years or change your family history, but there are many other stroke risk factors that you can control—provided that you’re aware of them. “Knowledge is power,” says Dr. Natalia Rost, associate professor of neurology at Harvard Medical School and associate director of the Acute Stroke Service at Massachusetts General Hospital. “If you know that a particular risk factor is sabotaging your health and predisposing you to a higher risk of stroke, you can take steps to alleviate the effects of that risk.”

Here are seven ways to start reining in your risks today, before a stroke has the chance to strike. Continue reading
