Bad sleep habits may
set you up for poor blood sugar control. Sleeping for less than 6 hours or more than 9 hours per night was
associated with an increased risk of diabetes in a recent study. These same
poor sleep habits also were linked to impaired glucose tolerance, a condition
marked by higher-than-normal blood sugar levels. Aim for 6 to 8 hours of sleep
per night.
A recent study revealed that sleep deprivation reduces levels of leptin, an
appetite-suppressing hormone. If you have trouble sleeping, practice good sleep
hygiene: go to bed at the same time every night, avoid caffeine or large meals
late in the evening, exercise regularly earlier in the day, sleep in a cool,
dark room, and unwind before bedtime.
Add a good night's
sleep to your checklist of helpful weight-loss aids. Sleep deprivation interferes with appetite-suppressing hormones, increases
stress hormone levels, and decreases a person's glucose tolerance, all of which
may contribute to weight gain. Another way sleep loss may help pile on the
pounds: late-night munching. Go to bed and get up at the same time each day to
help achieve sounder sleep.
Mind Meltdown
Brain scans of sleep-deprived people performing gambling tasks showed something
quite revealing: The orbitofrontal cortex, an area that aids in learning from a
loss or a bad decision, was less active. Researchers suspect that poor sleep,
besides prompting risky behaviors, hinders the brain's ability to process
emotions, such as regret. The result? You're less likely to think about the
consequences of a decision. This leads to poor nutrition choices!
Overweight and obese adults are more likely to report skimping on sleep
compared to people with healthy body mass indexes.
Shortchanging
yourself on ZZZs makes your heart work harder.
Here's how: When you sleep, your body goes into a lower
blood pressure mode. But too little time in this low-key state can eventually
lead to high blood pressure. So set the list aside and give your heart a little
holiday instead.
If you've traded sleep time for to-do lists, tight deadlines, or fretful
toddlers, you're like most people over 30 who are getting historically low
levels of sleep. One study of people aged 32 to 59 found that those who got
fewer than 5 hours of sleep a night for several years were twice as likely to
develop hypertension as people who got a healthy 7 or 8 hours each night.
Cutting back on a full night's sleep again and again comes back at you in
several ways:
- It deprives you of the time when your blood
pressure is lower.
- It means you spend more time dealing with stress
instead of resting.
- And salt retention, a well-known contributor to
high blood pressure, may increase with sleep deprivation.
Frozen, fresh, or
cooked veggies?
You'd think that boiling veggies would suck the nutrients
right out of them. But in the case of carrots and broccoli, that may not be so.
Seems that lightly boiling these two veggies can actually increase the
concentration of carotenoids. The downside? It also depletes their phenolic
compounds.
Steaming may be your best bet for both preserving phenolic compounds and
boosting bioavailable carotenoids -- at least for broccoli. For carrots, you'll
have to choose what's more important to you.
Whatever cooking method you choose for your veggies, keep in mind that frying
or sauteing kills off the most antioxidant compounds.
Try out these other tips and tricks to make your veggies extra nutritious:
- Skip the thaw. Cooking
straight from frozen retains more vitamin C.
- Spice them up. Adding
cumin, ginger, and sage, rosemary, marjoram, and thyme will boost the
antioxidant punch of both raw and cooked veggies.
Fresh is best when it really is farm-fresh and ripe.
However, many commercial fruits and veggies are picked before peak ripeness --
which also means before their nutritional peak -- to avoid spoilage during
transport and storage. And just a few days after harvest, fruits and vegetables
begin to lose some of their nutritive goodness. What's more, the longer they
sit on the shelf -- during transport, in the supermarket, and in your fridge --
the fewer nutrients they have left to pass on to you.
On the other hand, fruits and vegetables intended for freezing are usually
picked closer to the peak of ripeness and are flash-frozen immediately after
harvest. The processing does deplete some nutrients, but it locks in the rest
for up to 12 months. So in some instances, frozen fruits and veggies may
actually have more of the vitamins and minerals your body needs.
Numerous studies show
that getting more of the omega-3 fatty acid called DHA (docosahexaenoic acid)
in your diet may boost your mood and your brainpower. Even people battling
tough-to-treat depression may feel as much as 50% better when they get lots of
DHA. To keep your chin cheerfully up, aim for 200 milligrams (mg) of DHA a day.
1 Farm egg (150 mg)
Spinach is full of folate, a B vitamin that's a must for
making feel-good serotonin. Like DHA, folate may help ease depression,
according to researchers.
· Add a 10-ounce packet of frozen chopped spinach to soups, stews, and
casseroles, homemade or not.
· Use spinach instead of lettuce in sandwiches and wraps.
Eating lutein-rich
spinach every day for six months was enough to improve the vision of people
already suffering from AMD.
Lutein and
Zeaxanthinis found in high
amounts in:
- Kale and spinach
- Turnip and collard greens
- Romaine lettuce
- Broccoli
- Zucchini
- Brussels sprouts
There
is about 0.25 mg of lutein in each egg yolk -- in a highly absorbable nearly
ideal form. Egg yolks also have zeaxanthin in an equal amount.
Quite simply, the lutein in egg yolks is superior because it is more easily
absorbed by your body. A study in the Journal of Nutrition even proved this.
Your Mother Was Right -- and Wrong -- About Washing Fruits and
Vegetables
Soaking your food in water
saturated with ozone will not only selectively kill all the microbes on your
produce BUT, and more importantly for most of us, it will break down all the
pesticides that are on the outside of the vegetables.
Ozone, unlike radiation or chemicals, will not damage the vitality of the
produce you are going to consume. This is FAR safer than soaking your produce
in bleach, which while it will work, is clearly toxic to you.
Ozone can be toxic if you breathe it in large quantities, but when it is
dissolved in water and acting on the vegetables, it is completely harmless.
The name of the product is the Lotus
Sanitizing System. You can pick
up this handy, device at Amazon for a little over $100.
OR soak your vegetables in
water from a www.wetcooler.com water
cooler.
The FDA is Pushing Dangerous and Damaging Ways to Sanitize Foods
The U.S. Food and Drug Administration (FDA) has been considering irradiation
since 1999. What exactly is irradiation?
Irradiated foods are exposed to a radiant energy source such as gamma rays or
electron beams, which create positive and negative charges. This process
disrupts the genetic material of living cells, which kills pathogens, insects
and just about anything. The process also extends the shelf-life of foods, as
the FDA boasts that “irradiated strawberries stay unspoiled up to three weeks,
versus three to five days for untreated berries.”
Irradiation Also Destroys Nutrients
It says so right on the
FDA’s Web site:
“The process [irradiation] may cause a small loss of
nutrients but no more so than with other processing methods such as cooking,
canning, or heat pasteurization.”
Raw foods rule! The moment you cook, heat, pasteurize or irradiate most food
you lose a major element of its vitality. The energetic element of food -- such
as biophoton nutrition -- is largely undervalued in the United States,
and the only way to get it is from raw foods.
Meanwhile, when foods are cooked or heated:
- Nutrients, like vitamins,
minerals, and amino acids are depleted, destroyed, and altered.
- The biochemical structure and
nutrient makeup of the food is altered from its original state. Molecules
in the food are deranged, degraded, and broken down.
- The interrelationship of
nutrients is altered from its natural synergistic makeup.
- All of the digestive-friendly
enzymes present in raw foods are destroyed.
So imagine what would happen if ALL food, including your
fresh produce, was irradiated before it reached your hands. These once lively
and health-giving foods would be, literally, dead. And they would not provide
the health benefits that raw, natural foods are known for.
Well, There Was That Spinach Scare
You remember, back in 2006, during which all spinach
was pulled from store shelves.
Well, the researchers that are behind the above study are using that as a
springboard to suggest that irradiation is necessary for fruits and vegetables.
A similar thing happened after a couple of salmonella outbreaks in 2001 and
2004 were traced back to raw almonds. The USDA then announced that they would require all raw
almonds to be pasteurized. Now, if you want to buy truly raw
almonds, you have to get them from a grower overseas.
So if the idea of irradiating fresh produce sounds like a long-shot, it may not
be so far off. The USDA is applying its flawed logic once again, and suggesting
that since it is possible to become sick from a raw food, you had best kill
everything on it (good or bad) before you eat it.
You Can Avoid Irradiated Foods
For now, food that is irradiated must be labeled as such (except for spices,
which are usually irradiated and not labeled). This may not be the case for
long, however, as the FDA is considering allowing some irradiated
foods to simply be labeled as pasteurized.
For now, though, keep a look out for foods labeled as "treated with
radiation," "treated by irradiation,” or that contain the
international symbol for irradiation, the radura:
Remember that what’s needed to keep your food supply safe is not a hefty dose
of irradiation. What are needed are healthy animals and non-toxic growing
practices. So if you want to find food that is safe for you and your family,
avoid the symbol above like the plague, and buy your food from a local farmer
near you who still takes pride in raising food the healthy
“old-fashioned” way -- no irradiation required.
If the FDA gets its way, as long as the food looks and smells normal,
chances are better than good you won't know whether that specific food has been
"nuked" or not.
Rightly so, consumer groups aren't at all happy with the proposal that
"would deny consumers clear information about whether they are buying food
that has been exposed to high doses of ionizing radiation," according to
Food & Water Watch. Industry groups like the Grocery Manufacturers/ Food
Products Association are elated about it, however, considering the irradiated
label has such a negative impact on consumers it acts like "a warning
label."
Well, it should be a warning label!
Research has revealed a wide range of problems in animals that eat
irradiated food, including premature death, a rare form of cancer, reproductive
dysfunction, chromosomal abnormalities, liver damage, and vitamin deficiencies.
Irradiation also destroys vitamins, disrupts the chemical composition of food,
and masks and even encourages filthy conditions in slaughterhouses and
food-processing plants.
All the more reason you should stay away from processed foods
entirely, restrict your meat choices to grass-fed or organic meats
and seek out local sources
for the foods you eat.

The Vitamin That Could Add Years to Your Life
If there were an Olympics for anti aging nutrients, vitamin
D would have a good shot at the gold medal. Here's why: Scientists recently
examined how blood levels of vitamin D affect aging on a cellular level. High
intake was associated with as much as 5 fewer years of chromosome aging!
New Wonder Vitamin
D seems to be particularly relevant to a cellular yardstick of aging called a telomere.
These "end caps" on your chromosomes get shorter and shorter with
age, but having high blood levels of vitamin D seems to help ensure longer
telomeres. That's a good thing, because when telomeres get really short
and disappear, cells stop dividing and start to die. Translation: You age and
become more vulnerable to disease.
Every time a cell reproduces, the telomere
gets a little shorter. Over time, once the protective covering on the tip wears
away, your DNA shoelace begins to fray. The cell stops dividing and can no
longer replenish your body. Each time a telomere retires, you age a little.
So, get this: The telomeres of people who feel more
stressed are almost 50% shorter than people who say they’re less stressed.
Since scientists have a rough idea of what the average telomere length is for a
specific age, they can estimate how much older the higher stress group is
biologically: a whopping 9 to 17 years!
More D Delights
For years, D -- a vitamin found in food but also synthesized by your skin with
a bit of sun exposure -- has been a nutritionist's delight because of its
impact on bone health. Now, evidence is growing that the vitamin not only helps
build bone and thwart aging but also defends against multiple sclerosis, several cancers, and inflammation disease. D is
definitely moving into bona fide supernutrient territory.
Better Get Yours
Milk remains an excellent source of vitamin D, with 100–125 international units
(IU) per cupful. Not into milk? Here are a few other sun-free ways to get your
fill of D:
- Choose fortified foods.
Food manufacturers are catching on: We want more D! Check the labels of
everything to see if they're fortified.
- Eat fish. The richest
source of D is salmon (360 IU of vitamin D in 3.5 ounces), but tuna and
sardines canned in oil are good sources, too.
- Have an egg. D is in
the yolk, and although 26 IU doesn't sound like much, it all adds up.
- Take a supplement.
Just stay below 2000 IU per day from food and supplements combined. Ask
your doctor for the best supplement and get your Vitamin D levels tested before
you start supplementation.
Why You Should Snap Up Asparagus
Seems that getting lots of folate -- specifically from food,
not so much from supplements -- may help protect you from pancreatic cancer.
And just half a cup of asparagus delivers 190 micrograms of the stuff, more
than 25 percent of what you need.
Your Pancreas, and More
Folate is a member of the B-vitamin group, and it has long been touted as a
heart helper. Some early research also links high folate intake to a lower risk
of colon, breast, ovarian, and lung cancers.
Food Is a Factor
Folate from both food and the stuff found in supplements (folic acid) helps
your heart. But in scientific studies,
when it came to defending against pancreatic cancer, only food sources seemed
to have an effect. Folate-rich foods aren’t hard to come by if you go for the
green -- as in artichokes, brussels sprouts, lima beans, avocados, soybeans,
and broccoli and asparagus.
