Think
Feet With Diabetes
About 2
million Canadians are currently living with diabetes. It can
be a "silent" disease, as patients may have few symptoms.
Once diagnosed with diabetes it is of great importance to be
vigilant of lifestyle and nutrition to keep the condition under
control. A common problem for about 15% of diabetics is the
development of a diabetic foot ulcer. Of those afflicted 14-24%
will require an amputation of a lower extremity as a result.
In addition to this the mortality rate of patients with below
knee amputation due to the complications of a diabetic foot
ulcer is 19-55% after three years.
Even though these statistics sound ominous, a lot can be done
in the way of prevention. According to the Canadian Diabetes
Association guidelines, a diabetic patient should have a foot
exam performed at least annually. Diabetic peripheral neuropathy
is the leading cause of diabetic foot ulcers. The physician
can examine the feet for loss of sensation. He will check for
foot calluses and will debride those, which are pre-ulcer state.
The physician also checks for poor circulation in the foot at
that time.
If there is no loss of protective sensation, an annual exam
will suffice, but if there is loss of sensation, several exams
per year may be needed. A vascular surgeon may have to assess
the patient to see if the foot circulation is sufficient. Infection
is a warning sign and has to be treated promptly. Finally, any
source of pressure to the foot needs to be removed or offloaded.
A proactive approach to keep the feet healthy starts at home.
The following
points are important especially to the patient with diabetes:
-Inspect your feet on a daily basis. Check for sores, blisters
or cracks that don't heal.
-Check your footwear. If there is debris (sand, pebbles) remove
promptly.
-Wash your feet daily with warm, not hot water and dry them
well, especially between your toes.
-Trim your toenails. If you have difficulties doing that, seek
out the help of a podiatrist. Also don't use the homemade approach
cutting corns and calluses.
-Keep the circulation to your feet going: put up your feet when
you sit. Wiggle your toes, move your ankles, don't cross your
legs for long stretches of time.
-Shop for suitable footwear! Ask the sales clerk to measure
both of your feet in order to determine the proper size. Shop
in the afternoon, as your feet can swell during the day.
-Don't break in a tight fitting new show! This may injure your
feet. A new shoe should be comfortable right away.
-Don't delay looking after problems. If a cut, sore, bruise
or blister does not start to heal after a day, see a physician.

Houseplants
Responsible For Allergic Reactions
Generally
house dust and dust mites, pet dander, feathers, moulds and
ragweed are meantioned, when it comes to the topic of allergies.
Nuts and peanuts have also been associated with violent allergic
reactions.
With skin prick tests (SPT) the allergists can very clearly
determine what substances the allergy sufferer is sensitive
to.
A small
study, which appeared in the September edition of Allergy has
shown that allergic rhinitis in a patient, can have its origin
in exposure to houseplants. Allergic rhinitis with a runny nose
and sneezing is often neglected, as-opposed to asthma or an
urticarial rash. It is perceived as more of a nuisance than
a threat. Allergic rhinitis sufferers were subjected to SPT's
along with a healthy control group. 78 % of allergic rhinitis
patient had a positive STP to at least one plant, while none
of the control group developed significant reactions to any
of the tested plants.
The plants that produced the most frequent sensitization were
Ficus benjamina, yucca, ivy and palm tree.

Diverticulitis
Associated With Obesity
Medical
textbooks used to describe acute diverticulitis as a disease
that was mostly seen in adults over 50 years of age. Researchers
at the University of Maryland Medical Center have assessed the
medical records of 104 patients ages 22 to 88 years with the
condition of diverticulitis diagnosed between 1999 and 2003.
56 patients (54%) were age 50 or younger, and the remaining
48 (46%) were over 50. The researchers found that a significantly
higher proportion of patients (88 %) with abdominal obesity
were present in the younger age group with diverticulitis.
Acute diverticulitis is a condition characterized by the chronic
inflammation of sacs in the intestinal tract. The condition
causes constipation and severe abdominal pain. It is usually
related to a low fiber diet containing refined carbohydrates
or processed foods.
Dr. Barry who was leading the study observed that the younger
the patients with diverticulitis are, the more obese they are
likely to be. Also, he found the younger they are when they
get the disease, the more likely they will get recurrent attacks,
and he sees the most important point in diverticulitis prevention
is a change to healthy eating habits without overprocessed food
from fast food outlets.

Body
Can Fight Weight Loss
Embarking
on a weight loss program needs long-term commitment and persistence.
Many dieters have experienced the yo-yo effect of good initial
results in losing weight, after which the weight loss stopped,
and gradually the weight was gained back. Often dieters blame
themselves for their lack of success or are criticized for a
lack of self-control.
The "plateau effect" has been discussed and documented
before, and now an Australian study has found that "it
is not just you". After initial success and weight loss
the human body is designed to strongly resist attempts to lose
weight. Dr. Neil King from Queensland University of Technology
does research on appetite regulation and energy balance. He
conducted studies on groups of people who were overweight and
obese people. He found that weight loss from exercise and calorie
restriction stops at a certain point, and this plateau remains
firmly in place for a prolonged time, despite continuing dieting
and exercise.
In the first
study 30 obese men and women from Britain took part in a 12-week,
laboratory based exercise program in which they exercised five
times a week. The second study observed the weight loss in 200
Australian men who were enrolled in a commercial weight loss
program, which involved both an exercise program and dietary
advice. Although both groups followed different plans, their
weight loss still plateaued. The first group averaged a loss
of 3 kg during the first 8 weeks, and weight loss in the next
4 weeks was markedly reduced (0.7 kg). The second group had
a variable pattern of weight loss, but it, too, showed a plateau.
Researchers
believe that the human body is designed to cope with famine.
As a result there is a built-in mechanism responsible for weight
loss resistance. It may be a source of frustration to people
on a weight loss program in a society where there are no food
shortages, but it is meant to be a lifesaver in times when there
was a shortage of food.
For the person who wants to lose weight it involves taking a
closer look at the caloric output. Longer exercise times, higher
intensity or cross training can combat the plateau effect, but
patience is also needed along with the determination to carry
on with the program.

Eat
Your Salad Greens, But No Spinach
Spinach
has traditionally been regarded as a healthy, green leafy vegetable
and a valuable source of vitamins and minerals, in particular
iron. The tedious chore of cleaning the tender greens and removing
soil and sand traces has been taken care of by packinghouses.
As a result, the consumer could purchase ready to eat spinach
in plastic bags. These greens were a welcome ingredient for
spinach salads or other dishes.
Lately all spinach has been recalled from the world's largest
producer of organic produce. Natural Selection Food has recalled
a total of 34 brands that were distributed nationwide, and some
of which were available also in Canada. Consumers are still
being warned not to eat fresh spinach from the U.S., even though
there have been no reported cases of ill effects or diseases
in Canada itself. Problems have surfaced in September in form
of food borne illness in the U.S. The culprit seems to be contamination
with E. coli 0157:H7. Food borne illness can be serious. So
far there have been 109 cases of illness in the U.S. and possibly
two deaths. The worst affected area so far is Wisconsin, where
29 illnesses were reported and one person died of the disease.
As a result of this alert, salad mixes that contained a variety
of greens including spinach leaves have also been pulled from
the shelf. It should be mentioned that washing the spinach leaves
does not make it safe to consume, as the E.coli bacteria stick
to the leaves.
While it seems good-bye to spinach leaves for now, it remains
important to eat your greens. Researchers at University of California
in Los Angeles and colleagues at Louisiana State University
analyzed the salad consumption based on the intake of salad,
raw vegetables and salad dressing on 9,406 women and 8,282 men.
The researchers also found from their studies that daily consumption
of salad and raw vegetables is not the norm in any population
group and even less prevalent among African Americans.
There were data from lab tests on serum nutrient levels, and
it showed that consumption of salads was positively associated
with above-median serum micronutrient levels of folic acid,
vitamin C and E, lycopene, and alpha carotene and beta carotene.
All of these nutrients are important for healthy daily functioning.
They are weapons that help fight infection, heart disease and
cancers. The consumption of salad and raw vegetables remains
the most effective strategy for increasing the intake of important
nutrients.
