De zaadvliezen en de zaden van een bepaalde
soort weegbree, psyllium, hebben effect op de bloedsuikerspiegel bij diabetespatienten.
Blonde Psyllium, in het Nederlands Vlozaad, heeft tevens een positief effect op het
cholesterol in het bloed. De zaden hebben vezels in zich die bulk vormen in de darmen. Ook
bevatten de zaadvliezen slijm, dat met water een massa vormt.
Pistachio Power - Lowers Cholesterol And Blood Sugar, Relieves Stress
The pistachio nut, a native to the Middle East, is one of the oldest flowering nut trees
with archaeological evidence of the nut dating back to 7,000 BC.
Low-glycemic diet shows greater
improvement in glycemic control than high-fiber diet
Persons with type 2 diabetes who had a diet high in low-glycemic foods such as nuts, beans
and lentils had greater improvement in glycemic control and risk factors for coronary
heart disease than persons on a diet with an emphasis on high-cereal fiber, according to a
study in the December 17 issue of JAMA. One dietary strategy aimed at improving both
diabetes control and cardiovascular risk factors is the use of low–glycemic index
diets, but there is disagreement over their effectiveness, according to background
information in the article. David J. A. Jenkins, M.D., of St. Michael's Hospital and the
University of Toronto, and colleagues assessed the effects of a low–glycemic index
diet vs. a high–cereal fiber diet on glycemic control and cardiovascular risk factors
for 210 patients with type 2 diabetes. The participants, who were treated with
antihyperglycemic medications, were randomly assigned to receive 1 of the 2 diet
treatments for 6 months. In the low–glycemic index diet, the following foods were
emphasized: beans, peas, lentils, nuts, pasta, rice boiled briefly and low–glycemic
index breads (including pumpernickel, rye pita, and quinoa and flaxseed) and breakfast
cereals (including large flake oatmeal and oat bran). In the high–cereal fiber diet,
participants were advised to take the "brown" option (whole grain breads; whole
grain breakfast cereals; brown rice; potatoes with skins; and whole wheat bread, crackers,
and breakfast cereals). Three servings of fruit and five servings of vegetables were
encouraged on both treatments.
Researchers at Columbia University
Medical Center link blood sugar to normal cognitive aging
Maintaining blood sugar levels, even in the absence of disease, may be an important
strategy for preserving cognitive health, suggests a study published by researchers at
Columbia University Medical Center (CUMC). The study appeared in the December issue of
Annals of Neurology. Senior moments, also dubbed by New York Times Op-Ed columnist David
Brooks as being "hippocampically challenged," are a normal part of aging. Such
lapses in memory, according to this new research, could be blamed, at least in part, on
rising blood glucose levels as we age. The findings suggest that exercising to improve
blood sugar levels could be a way for some people to stave off the normal cognitive
decline that comes with age. "This is news even for people without diabetes since
blood glucose levels tend to rise as we grow older. Whether through physical exercise,
diet or drugs, our research suggests that improving glucose metabolism could help some of
us avert the cognitive slide that occurs in many of us as we age," reported lead
investigator Scott A. Small, M.D., associate professor of neurology in the Sergievsky
Center and in the Taub Institute for Research on Alzheimer's Disease and the Aging Brain
at Columbia University Medical Center.
High insulin levels raise risk of
breast cancer in postmenopausal women
Higher-than-normal levels of insulin place postmenopausal women at increased risk of
breast cancer, researchers at Albert Einstein College of Medicine of Yeshiva University
report. Their findings, published in the January 7 issue of the Journal of the National
Cancer Institute, suggest that interventions that target insulin and its signaling
pathways may decrease breast cancer risk in these women. Breast cancer is the most common
cancer among women in the United States. Last year, approximately 182,000 women were
diagnosed with breast cancer and more than 40,000 died from the disease. The majority of
breast cancers arise in women past the age of menopause. Obesity is a well-established
risk factor for postmenopausal breast cancer, but just how obesity and breast cancer are
connected is unclear. Many researchers have assumed that the link is estrogen—a
hormone that is known to increase breast-cancer risk and is found at higher-than-average
levels in obese women. But obese women also have other hormonal imbalances that may play a
role in triggering breast cancer. One such imbalance is elevated levels of insulin, which
stimulates the growth of breast cells in tissue culture. The Einstein study is the first
to prospectively identify insulin's role in breast cancer while controlling for estrogen
levels. The multi-year Women's Health Initiative (WHI)—the largest study of
postmenopausal women ever funded by the National Institutes of Health—followed health
outcomes in more than 93,000 postmenopausal women. At enrollment, each participant donated
blood samples that were stored for later analysis.
High-glycemic index carbohydrates
associated with risk for developing type 2 diabetes in women
Eating foods high on the glycemic index, which measures the effect of carbohydrates on
blood glucose levels, may be associated with the risk for developing type 2 diabetes in
Chinese women and in African-American women, according to two studies in the Nov. 26 issue
of Archives of Internal Medicine, one of the JAMA/Archives journals. However, eating more
cereal fiber may be associated with a reduced risk for type 2 diabetes in African-American
women.
De rol van stress, sport,
suikerspiegel bij buikvet
Buikvet is eigenlijk stressvet. Ik heb
gekeken wanneer cortisol hormoon op zijn hoogst staat want deze jaagt namelijk ook je
suikerspiegel op. De piek zit tussen 6 en 10 uur en dan daalt hij. Om 1/2 4 smiddags is
hij erg laag. Door juist koolhydraten te eten wanneer cortisol laag is voorkom je
dus vetopslag bij mensen die fysiek de suikers niet meteen gebruiken voor beweging. Ook
savonds na 8 uur is je cortisol laag. Doe er je voordeel mee. Ik eet voor 12 uur dus
geen suikers (granen, rijst, banaan) meer, alleen appel, bessen, komkommer,
kokosolie en eiwit (gekookt ei, kip, kalkoen of vis) etc. En roken verhoogt ook je
cortisol en dus je suikerspiegel, daarom worden rokers die al een hogere suikerspiegel
hebben juist wel dik van roken en mensen met een lage suikerspiegel niet.
Op termijn veroorzaakt dit opjagen van je
suikerspiegel prediabetes dat zorgt voor de bekende schade aan je bloedvaten waardoor
menig roker (en zeker vrouwen) hun pensioen niet zal halen. De combinatie van roken en
diabetes is helemaal fataal. Zeker als je weet dat een rokende vrouw gemiddeld 16 jaar
eerder een hartaanval krijgt (64 ipv 80 jaar) dan een niet rokende vrouw. Sport is
voor stressgevoelige mensen niet ontspannend en jaagt cortisol alleen nog meer omhoog,
gestresste mensen worden dus door cardiofitness nog gestressder. Daarom had ik ook altijd
giga honger na de sport, want suikerspiegel was opgejaagd, suikers op en dan giga dip in
suikerspiegel door aanmaak van insuline. Iemand die gestresst is kan dus beter kiezen voor
wandelen, yoga, sauna etc. Hoog stresshormoon (cortisol) betekent namelijk een hogere
suikerspiegel en dus meer kans op vetopslag op de buik.
Ook nuttig om te weten, wat je smorgens
doet met je suikerspiegel werkt 10 uur door in de loop van de dag. Kun je dus je
suikerspiegel met eiwit, vet, groente en fruit mooi stabiel houden in de morgen dan hebt
je daar de rest van de dag voordeel van. En zorg voor ontspanning, stress is de ergste
toxine op deze planeet......en we maken hem zelf....

Slow Starch Diet Helps With Weight,
Diabetes
Troxler's diet is simple. It's based on low-fat, low-glycemic foods, which he said leaves
people feeling full without the large amounts of sugar and fat other foods contain.
Dr. Troxler has invested hundreds of hours educating others about this Slow Starch Diet,
also known as the Low Glycemic Index Diet. His lectures are designed to teach people how
to eat low-glycemic index foods. Glycemic Index is a measure of how fast the starch we eat
changes into blood sugar. Slow starch has a low glycemic index and causes only a slow rise
in blood sugar.
Low-carb diet reduces inflammation
and blood saturated fat in metabolic syndrome
Metabolic syndrome is a pre-cursor to diabetes, coronary heart disease, and other serious
illnesses. Patients have long been advised to eat a low-fat diet even though carbohydrate
restriction has been found to be more effective at reducing specific markers, such as high
triglycerides. A new study indicates that a diet low in carbohydrates is also more
effective than a diet low in fat in reducing saturated fatty acids in the blood and
reducing markers of inflammation.
Waistline Growth On High-carb Diets
Linked To Liver Gene
Experts have been warning for years that foods loaded with high-fructose corn syrup and
other processed carbohydrates are making us fatter. Now, a University of Wisconsin-Madison
study has uncovered the genetic basis for why this is so.
Carb consumption presents potential
link to diabetes risk
Researchers urge students to begin watching diet and weight now, following recent findings
that suggest intake of foods with a high glycemic index may increase the risk of Type 2
diabetes.
Starchy foods such as white rice and bread raise the likelihood of diabetes for both black
and Chinese women, but adding some whole-grain foods may reverse the risk, researchers
reported.
Drinking coffee appears to hamper efforts by people with type 2 diabetes to control their
blood sugar levels, and can exaggerate the blood sugar rise which occurs after each meal,
according to new research.
In the journal Diabetes a research team from Umeå University and Stockholm University in
Sweden presents findings that indicate that elevated levels of blood sugar may have a
negative impact on the memory function. It was previously known that patients with
diabetes run a higher risk of developing various forms of dementia, including
Alzheimer’s disease. This increased risk may be caused by a combination of the risk
factors for cardiovascular disorders that this patient group has, including high blood
pressure, high blood fats, heightened inflammatory activity, and high blood sugar.
Previously it was not know whether blood sugar alone could have a negative effect in
people without diabetes, and it has also been unclear what part of the brain might be the
most sensitive to high blood sugar levels. By analyzing 411 healthy people who took part
in both Västerbotten Health Examinations and the Betula Project, the research team has
been able to established that elevated blood sugar levels probably affect a specific part
of the brain, the hippocampus, and especially in women. The hippocampus is a part of the
brain that stores memories, and it is often the first part of the brain to be impacted
with the onset of Alzheimer’s disease. The study provides key information that can
serve as a basis for further studies designed to examine how elevated blood sugar can
affect the memory.
Relationships of low serum vitamin
D3 with anthropometry and markers of the metabolic syndrome and diabetes in overweight and
obesity
Previously reviewed mechanisms include that 1) low vitamin D3, may impair insulin action,
glucose metabolism and various other metabolic processes in adipose and lean tissue 2) fat
soluble-vitamin D3 is sequestered in the large adipose compartment, and low in serum, 3)
obese people may be sensitive about their body shape, minimising their skin exposure to
view and sunlight (not tested). We showed evidence for the first theory but no evidence to
support the second. In the current study, serum vitamin D3 was inversely related to
weight, BMI and markers of TIIDM (large waist, raised HbA1c) but not to adipose mass nor
to MetSyn per se.
Spices may protect against
consequences of high blood sugar
Herbs and spices are rich in antioxidants, and a new University of Georgia study suggests
they are also potent inhibitors of tissue damage and inflammation caused by high levels of
blood sugar.
When mice that lack steroid receptor-2, a master regulator gene called a coactivator, fast
for a day, their blood sugar levels plummet. If they go another day without food, they
will die. The severity of the hypoglycemia was unexpected, said Dr. Bert W. O'Malley,
chair of molecular and cellular biology at Baylor College of Medicine and senior author of
the report on the study that appears in the current issue of the journal Science.
Whole Grains Found to Stabilize
Blood Sugar For up to Ten Hours
When eaten as part of a breakfast with a low glycemic index, whole grains can help control
blood sugar all day long, according to a study conducted at Lund University in Sweden. A
breakfast with a low glycemic index even appeared to improve alertness and mental
function.
Fatty Liver Risk Linked To High
Glycemic Index Diet
Eating carbohydrates high on the glycemic index (GI) produced not only fatter mice, but
mice with fatty livers according to a recently published study (1). For twenty-five weeks
two groups of mice were fed a diet high in carbohydrates. One set had carbohydrates high
on the GI while the other group received carbohydrates low on the GI. At the end of the
study, both sets of mice weighed about the same, but the group that ate high on the GI had
twice as much total body fat, twice as much fat in their blood and twice as much fat
around their livers.
