on Diabetes
This post was in response to someone listing symptoms
of diabetes and asserting that I would enevitably end up with diabetes
due to my high fruit consumption. It has information I gathered from
various sources about diabetes and fruit. It was originally on the
VegSource Raw and Nutrition discussion board, but was deleted with
the whole thread as the orignal post was deemed too offensive by the
VegSource staff.
I personally had some of the symptoms of pre-diabetes
gathering after I stopped my high fat raw vegan diet and went back
to cooked, then lacto-veggie, then veggie+poultry and fish. They
are all gone now that I've been doing 811rv & my weight and
blood sugar are stablized.
I have never seen any scientific evidence of consumption
of fruit causing pre-diabetes or diabetes. In fact everything that
I could find suggests there is a definite connection between obesity
and/or excess dietary fat and the onset of Type 2 diabetes. There
is also a connection of stress as well as a diet low in fiber and
sedentary lifestyle. BTW, FYI – meat and animal products contain
no dietary fiber and fruits contain both soluble and insoluble fibers,
both of which maintain various functions – including blood
sugar levels. This is part of the reason why animal products and
juices are not recommended in 811rv BTW – lack of fiber in
both, can cause digestive and/or blood sugar problems. The fibers
in fruits are one of the main reasons why diabetics are encouraged
to eat fruits, even though their already established insulin resistance
makes the timing of all eating tricky if following the standard
food pyramid.
From the VegSource Raw & Sports board FAQs:
I have heard that too much sugar is not
good for you, so why the emphasis on eating so much sweet fruit?
Before the body’s cells can utilize food for
fuel, the food must first be converted into sugar, whether the
originating food is carbohydrate, protein or fat. Carbohydrates
are the easiest to convert to useful sugars. Fruits are mostly
simple carbohydrates. It is much easier on the digestive system
to process fruits for fuel because they are composed primarily
of sugars, requiring much less digestive energy, and they come
in a complete nutritional package of vitamins, minerals, proteins,
and fats. When there are insufficient carbohydrates present to
convert to sugar, the body will transform fat and protein into
sugar, but at a higher cost: more time and energy spent on digestion
with the creation of toxic residues.
The sugars that are not good for you are the refined
sugars (empty calories) and those that come from complex carbohydrates
such as pasta, rice, cereals and bread, which must be refined
and cooked and require a lengthy conversion process in the body.
Most of the so-called "sugar metabolic diseases," like
diabetes, that have made people afraid of fruit sugar are caused
instead, by excess fat. Still, "too much" sugar is indeed
bad for you. It ranges from difficult to almost impossible to
get too much sugar from fruit, however.
and
I have candida or a yeast infection, and I’ve
been told to avoid too much sugar. How can I eat so much sweet
fruit when it’s full of sugar?
Excess fat is the culprit in candida, not sugar, per se. When
fat levels in the blood rise, so does blood sugar, because excess
fat inhibits insulin from performing its function of escorting
sugar out of the bloodstream. The excess fat lines the blood vessel
walls, the cells’ insulin receptor sites, the sugar molecules
themselves, and the insulin with a thin coating of fat, thus blocking
and inhibiting normal metabolic activity. Too much sugar in the
blood is as life threatening as too little and can result in serious
illness or death. Yeast, or candida, is a constant presence in
the blood; it serves as a life preservation mechanism, blooming
when there is an excess of sugar in the blood stream to bring
blood sugar down to a non-threatening level. When the sugar is
distributed and used by the cells of the body, the yeast quickly
dies off as it is supposed to. If fat levels stay chronically
high due to a poor diet, sugar will remain in the bloodstream
and feed the large candida colonies instead of feeding the 18
trillion cells of your body. Starved for fuel, these cells can
no longer metabolize energy, and you become tired, and feel rundown.
Because all carbohydrate, fat, and protein that we eat is converted
to simple sugar (glucose) if it is to be used by the cells for
fuel, the way out of this cycle is not to eat less sugar, but
to consume less fat. When fat levels drop, the sugar starts to
get processed and distributed again, and the yeast levels drop
because there is no longer excess sugar available.
and
Is it all right to juice fruits and vegetables?
With a few exceptions, it is preferable to consume
the whole food rather than to extract part of it and drink it.
Drinking fruit or carrot juice without the pulp being present
to slow the absorption rate of the nutrients can spike the blood
sugar and throw your blood chemistry out of balance. Better to
consume the whole fruit. One exception is fresh-squeezed citrus
fruits, since a significant portion of the pulp is generally retained
with the juice. The other "exceptions" are to blend
fruits such as melons, and to make smoothies out of various fruits
like bananas and strawberries. Liquefying the entire fruit in
a blender turns it into a juice or a thick smoothie, while keeping
the entire nutritional package together. Blending whole tomato,
celery and orange together makes a thick, tasty, salad dressing.
Don’t believe me or the FAQs? Here are a few
online references that I just grabbed quickly…
From the site you linked us to (http://www.brist.plus.com/diet-fruit.htm, specifically):
Health Benefits
High in fibre and very low fat, fruit has many
health benefits. These include protection against Cancer and Coronary
Heart Disease - see the 5 a day link.
This makes fruit a recommended source of carbohydrate
for everyone but especially diabetics.
And from the same site
http://www.brist.plus.com/what.htm:
So What is Diabetes?
Diabetes is a condition where sugar (glucose) in
the blood is not processed normally by the body. Damage to many
of the bodies systems can begin to occur when sugar levels in
the blood are excessively high for prolonged periods. The higher
these blood sugar levels are and the more often they occur the
greater is the risk of damage.
and later in the same section:
In untreated Diabetics there is insufficient Insulin
produced by the Pancreas to mop up all the sugar in the blood
in the normal time leaving blood sugar levels high. This can be
due to a failure of the Pancreas in Type 1 Diabetes or due to
the body becoming resistant to Insulin with the body gradually
needing more and more Insulin to deal with the same amount of
sugar in Type 2 Diabetes.
From The
American Diabetes Association: All
About DiabetesDiabetes is a disease in which
the body does not produce or properly use insulin. Insulin is a
hormone that is needed to convert sugar, starches and other food
into energy needed for daily life. The cause of diabetes continues
to be a mystery, although both genetics and environmental factors
such as obesity and lack of exercise appear to play roles.
And from a different
page at the same site:
Which foods are unhealthy?
Fat is a nutrient, and you need some fat in your diet.
But too much fat isn't good for anyone. And it can be very harmful
to people with diabetes.
Too much fat or cholesterol may increase the chances
of heart disease and/or hardening of the arteries. People with diabetes
have a greater risk of developing these diseases than those without
diabetes. So, it is very important that you limit the fat in your
diet.
Fat is found in many foods. Red meat, dairy products
(whole milk, cream, cheese, and ice cream), egg yolks, butter,
salad dressings, vegetable oils, and many desserts are high in
fat.
I took their (American Diabetes Association) risk
test BTW, and even though my dad has diabetes, I scored as low risk.
The results also said
Keep your risk low by:
* Keeping your weight in control (or losing weight
if you are overweight)
* Staying active most days of the week
* Eating low fat meals high in fruits, vegetables and whole grain
foods
From their Evidence-Based
Nutrition Principles and Recommendations for the Treatment and Prevention
of Diabetes and Related Complications section on fat in
the nutritional guidelines for health professionals:
Recommendations
A-Level evidence
* Less than 10% of energy intake should be derived
from saturated fats. Some individuals (i.e., persons with LDL cholesterol
>=100 mg/dl) may benefit from lowering saturated fat intake to
<7% of energy intake.
* Dietary cholesterol intake should be <300 mg/day. Some individuals
(i.e., persons with LDL cholesterol >=100 mg/dl) may benefit
from lowering dietary cholesterol to <200 mg/ day.
B-Level evidence
* To lower LDL cholesterol, energy derived from saturated
fat can be reduced if weight loss is desirable or replaced with
either carbohydrate or monounsaturated fat when weight loss is not
a goal.
* Intake of trans-unsaturated fatty acids should be minimized.
* Reduced-fat diets when maintained long-term contribute to modest
loss of weight and improvement in dyslipidemia.
C-Level evidence
* Polyunsaturated fat intake should be ~10% of energy
intake.
and the section on prevention:
PreventionThe importance of prevention of diabetes
in high-risk individuals is highlighted by the substantial and
worldwide increase in the prevalence of diabetes in recent years.
Genetic susceptibility appears to play a powerful role in the
occurrence of type 2 diabetes in certain populations. However,
given that population gene pools shift quite slowly, the current
epidemic likely reflects marked changes in lifestyle. Lifestyle
changes that are characterized by decreased physical activity
and increased energy consumption have together promoted obesity,
which is a strong risk factor for diabetes that itself is influenced
by both genes and behavior. Despite the difficulty in maintaining
a reduced body weight long-term, several studies have demonstrated
the potential for moderate sustained weight loss to substantially
reduce the risk for type 2 diabetes. Clinical trial data from
both the U.S. and Finland now strongly support the potential for
moderate weight loss to reduce the risk for diabetes (6,7). An
active lifestyle also has been demonstrated in a number of prospective
studies to prevent or delay the development of type 2 diabetes.
Both moderate and vigorous exercise decrease risk of impaired
glucose tolerance and type 2 diabetes.
Reduced intake of total fat, particularly saturated
fat, may reduce risk for diabetes. Increased diabetes incidence
is reported with increased intake of dietary fat, independent of
total calories, although this effect is not demonstrated in all
studies. It appears that all types of dietary fat (except n-3 fatty
acids) may have an adverse effect on insulin sensitivity. Saturated
fat may have the greatest effect. Increased intake of polyunsaturated
fat, in the context of appropriate total energy intake for weight
management, may reduce the risk for type 2 diabetes.
Recent studies have provided evidence for reduced
risk of diabetes with increased intake of whole grains and dietary
fiber. Although selected micronutrients may affect glucose and insulin
metabolism, data to document their role in the development of diabetes
are scarce or inconsistent. Moderate alcohol intake has been related
to improved insulin sensitivity and reduced risk for diabetes. However,
insufficient data exist to support a specific recommendation for
moderate alcohol intake for prevention of type 2 diabetes.
No nutritional recommendations can be made for prevention
of type 1 diabetes. Breastfeeding may be beneficial. Although increasing
obesity in youth may be related to an increase in the prevalence
of type 2 diabetes, particularly in minority adolescents, there
is insufficient data at present to warrant any specific recommendations
for prevention of type 2 diabetes in youth. Increased physical activity,
reduced energy and fat intake, and resultant weight management may
prove to be beneficial.
and their section on special considerations for
Type 2 Diabetes:
Nutrition recommendations for a healthy lifestyle for the general
public are also appropriate for persons with type 2 diabetes. Because
many persons with type 2 diabetes are overweight and insulin resistant,
medical nutrition therapy should emphasize lifestyle changes that
result in reduced energy intake and increased energy expenditure
through physical activity. Many people with diabetes also have dyslipidemia
and hypertension, making reductions in dietary intake of saturated
fat, cholesterol, and sodium desirable. Therefore, the emphasis
of nutrition therapy for type 2 diabetes is on lifestyle strategies
to reduce glycemia, dyslipidemia, and blood pressure. These strategies
should be implemented as soon as the diagnosis of diabetes is made.
Increased physical activity can lead to improved
glycemia, decreased insulin resistance, and reduced cardiovascular
risk factors. Division of food intake, three meals or smaller
meals and snacks, should be based on individual preferences. Treatment
with insulin or insulin secretagogues requires consistency in
timing of meals and carbohydrate content. Multiple insulin dosing
regimens allow for a more flexible food intake and lifestyle in
persons with type 2 diabetes.
From the International
Diabetes Foundation: What is
diabetes?Diabetes is an illness which occurs
as a result of problems with the production and supply of insulin
in the body.
Most of the food we eat is turned into glucose, a
form of sugar. We use glucose as a source of energy to provide power
for our muscles and other tissues. Our bodies transport glucose
in our blood. In order for our muscles and other tissues to absorb
glucose from our blood, we need a hormone called insulin. Without
insulin, our bodies cannot obtain the necessary energy from our
food.
Insulin is made in a large gland behind the stomach
called the pancreas. It is released by cells called beta cells.
When a person has diabetes, either their pancreas does not produce
the insulin they need, or their body cannot use its own insulin
effectively.
As a result, people with diabetes cannot use enough
of the glucose in the food they eat. This leads to the amount
of glucose in the blood increasing. This high level of glucose
or "high blood sugar" is called hyperglycaemia. High
levels of glucose in the blood can lead to medical complications.
From Discovery Health on Insulin Resistance: All
meals become sugar
After you eat a meal, whether steak or vegetables or fish, it all
gets broken down into usable energy for the body — sugar.
While there are proteins and amino acids and other molecules that
are obtained from our diets, sugar, or glucose, is the main energy
source for our cells and especially our brains. So, to keep things
simple let's say that food and beverages (except water) become sugar
that will be transported via the blood to the tissues, muscles,
and organs.
Insulin: The key to sugar entry into cells
Insulin is the hormone responsible for getting the sugar shuttled
into our cells for use as energy. Insulin is frequently described
as the 'key' that unlocks the door to our cells allowing energy
to enter. The cells in our body can become resistant or less sensitive
to insulin and fail to open the door. This condition is known as
insulin resistance and is a pre-cursor to diabetes.
When our cells don't respond to insulin, excessive
amounts of sugar are left to float around in the bloodstream, this
is known as hyperglycemia. If not used, the excess sugar can then
be converted to and stored as fat. In addition to causing obesity,
the excess sugar can create problems in blood vessels and nerves,
as is seen with poorly controlled diabetes. Without realizing that
the cell is resistant to insulin, and in an attempt to correct the
situation, the body responds to the excess sugar by releasing more
insulin, which perpetuates the problem.
Insulin Resistance Promotes Fat Storage
Elevated insulin levels increase the transport of fatty acids, also
obtained from our diet, into fat cells. When fat cells are stuffed
with high levels of fat, the body beings to manufacture more fat
cells. While the body is able to add new fat cells, it is impossible
to reduce the number of existing fat cells via natural means.
So insulin resistance promotes fat storage by the
conversion of sugar to fat and fat cell stuffing. To make matters
worse, when the body becomes resistant to insulin, the metabolic
rate of the fat cell itself is also affected. Remember —
fat cells can give up FFAs and other molecules to provide energy
for the body in times of food shortage. Insulin resistance causes
fat cells to be broken down at a slower rate because there appears
to be plenty of fuel (sugar) around already.
From an article entitled, The Apple Figure and
Insulin Sensitivity: Take a Slice Out of Insulin Resistance
(talking about a body shape similar to an apple):
Why is the apple figure risky? Fat cells located in the
abdomen release fat into the blood more easily than fat cells found
elsewhere. Release of fat begins 3 to 4 hours after the last meal
compared to many more hours for other fat cells. This easy release
shows up as higher triglyceride (TG) and free fatty acid levels.
Free fatty acids themselves cause insulin resistance.
From http://www.rice.edu/~jenky/sports/Insulin.athlete.html: High
fat stores down-regulate insulin receptors and cause a resistance
to circulating insulin. The other 20% of insulin resistant individuals
-- who are not obese -- have a genetically inherited insulin receptor
that does not work properly. and It
is not hyperinsulinemia that is the problem, it is the receptor.
It has been repeatedly shown in the medical literature that increasing
the sensitivity of peripheral insulin receptors reduces hyperinsulinemia
and hypertension. This process is termed insulin sensitization and
is accomplished by aerobic exercise, low-fat / high-carbohydrate
diet, and reduction of excessive body fat. Conversely, obesity and
high fat diets have been shown to induce insulin resistance.
and
There are many published studies which show that starting
insulin resistant individuals on a high carbohydrate / low fat diet
reduces hyperinsulinemia, hypertension, and hyperlipidemia. For
example in a study published in the American Journal of Cardiology
(Am J Cardiol 1992;69:440-444), diabetic patients (NIDDM), insulin
resistant patients, and normal controls were started a 3 week program
of diet ( 75 - 80% carbohydrate, 10-15% protein, and <10% fat)
and exercise. In all there were statistically significant reductions
in blood pressure, insulin levels, and triglycerides. Additionally,
high-carbohydrate / high-fiber diets have been shown to lower cholesterol
and may reduce the risk of colon cancer.
From http://syndromex.stanford.edu/InsulinResistance.htm What
is Insulin?
Insulin is a hormone secreted by the pancreas. It helps the body
utilize blood glucose (blood sugar) by binding with receptors on
cells like a key would fit into a lock. Once the key insulin- has
unlocked the door, the glucose can pass from the blood into the
cell. Inside the cell, glucose is either used for energy or stored
for future use in the form of glycogen in liver or muscle cells.
What is insulin resistance?
Insulin resistance occurs when the normal amount of insulin secreted
by the pancreas is not able to unlock the door to cells. To maintain
a normal blood glucose, the pancreas secretes additional insulin.
In some cases (about 1/3 of the people with insulin resistance),
when the body cells resist or do not respond to even high levels
of insulin, glucose builds up in the blood resulting in high blood
glucose or type 2 diabetes. Even people with diabetes who take oral
medication or require insulin injections to control their blood
glucose levels can have higher than normal blood insulin levels
due to insulin resistance.
Why is insulin resistance in the news?
More and more people in the U.S. are becoming obese, physically
inactive, or both. Obesity and physical inactivity aggravate insulin
resistance. Also, people who are insulin resistant typically have
an imbalance in their blood lipids (blood fat). They have an increased
level of triglycerides (blood fat) and a decreased level of HDL
(good) cholesterol. Imbalances in triglycerides and HDL cholesterol
increase the risk for heart disease. These findings have heightened
awareness of insulin resistance and its impact on health. and What
is the best diet for people with insulin resistance?
Research indicates that low fat diets may aggravate the effect of
insulin resistance on blood lipids. Therefore, for individuals who
are insulin resistant, a diet low in saturated fat (less than 10
percent of total calories) and more moderate in total fat content
(40% of total calories) may be beneficial. This recommendation is
different from the low-fat, high-carbohydrate diet that many health
organizations recommend to help prevent heart disease. Specifically,
they recommend decreasing fat intake to less than 30 percent of
calories. Some groups recommend even lower levels of dietary fat.
It is also beneficial to maintain an appropriate body weight because
obesity can aggravate insulin resistance. To maintain an appropriate
weight, regulate caloric intake and maintain a physically active
lifestyle. A registered dietitian can assist with developing a proper
diet plan for people with insulin resistance, or a family history
of type 2 diabetes.
From The Health Report August 16, 2004 - Fat
Cells and Diabetes Type 2: Norman Swan:
One of the mysteries here, or one of the confusing things, if insulin’s
role is to get sugar from glucose, from the bloodstream inside cells,
why should there be all this activity in fat cells? Why aren’t
they just receptacles where you can go and pull your energy when
you need it?
Alan Saltiel: That’s a good question. I think
a lot of us are trying to figure this out right now, so it’s
kind of a mystery. In mice, where it’s been studied the best,
it’s very clear that insulin is the master regulator of the
clearance of sugar from the blood into cells, especially muscle
and liver. But also that the major regulator of the storage of energy.
In the case of muscle, energy is stored mainly as starch, in the
case of liver, it’s stored as starch and fat, and in the case
of the fat cell, it’s stored mainly as fat.
Norman Swan: So what you’re saying there before
you go on, is that insulin essentially can park long-term energy,
and in a sense it’s like a car park attendant?
Alan Saltiel: Yes, that’s exactly right, that’s
exactly what it does, or what it tries to do. What happens sometimes
though is that the ability of the fat cell to store fat is exceeded,
it reaches a threshold where the body almost starts to spill fat
out of the fat cell, and then it has to go somewhere, so it ends
up going into liver and muscle, and the accumulation of fact in
liver and muscle seems to make the liver and muscle less sensitive
to insulin. So insulin can now continue to be able to put down
energy and store energy as fat in those tissues, but loses its
ability to remove the glucose from the circulation, the sugar
from the circulation. So one of the consequences of that is something
that we call insulin resistance, where the body responds to the
fat storing effects of insulin, but fails to respond to the sugar
clearing effects of insulin.
From NutraIngredients
: Low Fat diet increases insulin
sensitivity06/02/2004 - Dutch scientists reveal
that low-fat product diet is better than smaller portions of normal
high-fat food for preventing diabetes in obese people.
Lead researcher Martin Muurling at the Netherlands
Organisation for Scientific Research put obese mice on different
diets in which the total energy intake and the final body weight
were the same. He then studied the impact of these diets on insulin
sensitivity.
He found that mice that only received low-fat products
were more sensitive to insulin than mice that ate small portions
of high-fat food. A low-fat diet is a more effective remedy for
diabetes than eating less calories, concluded the researcher.
He also reports that the consumption of fish oil had
no positive effects on reduced insulin sensitivity in the mice,
and notes that a diet with fish oil "cannot prevent or remedy
diabetes in the case of somebody who is already less sensitive to
insulin due to a high-fat diet".
Clinically obese people sometimes suffer from a certain
form of diabetes, type II diabetes mellitus, because more fatty
acids are released from the adipose tissue during obesity. These
fatty acids can reduce the functioning of the beta cells in the
pancreas as well as the sensitivity of various tissues to insulin.
From Eating
Well With Diabetes: Is it true
that I shouldn't eat bananas or grapes?
No - All fruits and vegetables are extremely good for you. Eating
more can reduce your risk of coronary heart disease, some cancers
and some gut problems. You should aim to eat at least 5 portions
of fruit and vegetables per day. This also helps to improve the
overall balance of the diet. Eat a variety a different fruits
and vegetables to ensure maximum benefit.
From Netwellness' FAQ
on Diabetes: Does eating a lot of sugar
really cause diabetes?
No. People who eat foods high in sugar are at risk
of gaining weight because sugar adds calories. Being overweight
is associated with developing Type 2 diabetes, but eating sugar
does not cause diabetes.
From Lifeclinic's section on sugar: A
high intake of sugar does not cause diabetes, but if a person is
diagnosed with diabetes the amount of simple sugar eaten daily often
needs to be reduced. and on Fats: Some
fat is also necessary to maintain healthy skin, hair and nails,
so you shouldn’t cut all fat out of your diet. But in general,
most people in the United States consume too much fat – which
can lead to heart disease, obesity, diabetes and many other health
problems. and on Diabetic
Diet:
Soluble fibers are found mainly in fruits, vegetables
and some seeds, and are especially good for people with diabetes
because they help to slow down or reduce the absorption of glucose
from the intestines.
From Medical
News Today:< Why is fiber (fibre)
important in your diet?
12 Jun 2004
What can fiber do for you? Numerous epidemiologic
(population-based) studies have found that diets low in saturated
fat and cholesterol and high in fiber are associated with a reduced
risk of certain cancers, diabetes, digestive disorders, and heart
disease.
However, since high-fiber foods may also contain antioxidant
vitamins, phytochemicals, and other substances that may offer
protection against these diseases, researchers can't say for certain
that fiber alone is responsible for the reduced health risks they
observe, notes Joyce Saltsman, a nutritionist with FDA's Office
of Food Labeling. "Moreover, no one knows whether one specific
type of fiber is more beneficial than another since fiber-rich
foods tend to contain various types," she adds.
From Fiber:
Not a Nutrient (but still necessary):
Fiber is only found in plant foods, such as fruits, vegetables,
and grains. It is NOT found in animal products like milk, cheese,
fish, poultry, or meat. Fiber gives the plants structure and is
indigestible by humans (it is digestible by some other animals,
such as cows). Since it is not digestible, it adds no calories.
Statistics have maintained that high fiber diets reduce cholesterol
levels and cancer rates.
