Memory Loss Can be Reversed

Moderate physical activity performed in midlife or later appears to be associated with a reduced risk of mild cognitive impairment -- and a six-month high-intensity aerobic exercise program can improve cognitive function in individuals who already have the condition.

Each year, 10 percent to 15 percent of individuals with mild cognitive impairment will develop dementia, as compared with 1 percent to 2 percent of the general population.

Physical exercise may protect against mild cognitive impairment by means of the production of nerve-protecting compounds, greater blood flow to the brain, improved development and survival of neurons and the decreased risk of heart and blood vessel diseases.

There is an old proverb that says: “Those who do not find time for exercise will have to find time for illness.”

It is virtually impossible to achieve optimal health without some type of regular exercise program. As you age, there is the potential for your brain function to steadily decline, leaving you confused and unable to care for yourself. However, your lifestyle, and specifically your dedication to regular exercise, can do wonders to keep your brain in top form, even later in life.

Impressive Brain Benefits from ExerciseIn the latest pair of studies to document the positive effects that physical exercise has on brain function, it was found that performing moderate exercise, such as aerobics, yoga and strength training during midlife lead to a 39 percent decreased risk of developing mild cognitive impairment.

Moderate exercise late in life was associated with a 32 percent lower risk. The second study even found that high-intensity aerobic exercise for six months was enough to improve brain function in those already suffering from mild cognitive impairment -- without the extra cost and dangerous side effects that occur when drugs are used instead. The authors stated: "Six months of a behavioral intervention involving regular intervals of increased heart rate was sufficient to improve cognitive performance for an at-risk group without the cost and adverse effects associated with most pharmaceutical therapies."

These are impressive results, considering that mild cognitive impairment affects about 20 percent of people over 70, according to the American College of Physicians. This condition often causes memory problems and blips in language, reasoning, judgment, and even reading and writing.

Mild cognitive impairment is often described as a transitory phase between normal brain function and more serious problems like dementia and Alzheimer’s disease. While 1 percent to 2 percent of people develop dementia, this rate rises to 10-15 percent among those with mild cognitive impairment. Thus, the more you can do to keep your brain functioning at its peak, and avoid any type of cognitive impairment whatsoever, the better off you will be.

How Does Exercise Protect Your Brain?Exercise encourages your brain to work at optimum capacity by causing your nerve cells to multiply, strengthening their interconnections and protecting them from damage.

Lab tests on animals have shown that during exercise, their nerve cells release proteins known as neurotrophic factors. One in particular, called brain-derived neurotrophic factor or BDNF, triggers numerous other chemicals that promote neural health. Further, exercise provides protective effects to your brain through:

*The production of nerve-protecting compounds
*Greater blood flow to your brain
*Improved development and survival of neurons
*Decreased risk of heart and blood vessel diseases

A regular exercise program can also slow the development of Alzheimer's disease by altering the way damaging proteins reside in your brain. In animal studies, significantly fewer damaging plaques and fewer bits of beta-amyloid peptides, associated with Alzheimer's, were found in mice that exercised.

Four Principles of ExerciseYour body is an efficient machine, and if you do the same type of exercise day after day, you’ll become quite good at it. However, when exercise becomes easy to complete, it’s a sign you need to work a little harder and give your body a new challenge.

So when you’re planning your exercise routine, make sure it incorporates the following types of exercise:

*Aerobic Jogging, using an elliptical machine, and walking fast are all examples of aerobic exercise. As you get your heart pumping, the amount of oxygen in your blood improves, and endorphins, which act as natural painkillers, increase. Meanwhile, aerobic exercise activates your immune system, helps your heart pump blood more efficiently, and increases your stamina over time.

*Interval (Anaerobic) Training: Research is showing that the BEST way to condition your heart and burn fat is NOT to jog or walk steadily for an hour. Instead, it’s to alternate short bursts of high-intensity exercise with gentle recovery periods.

This type of exercise, known as interval training or burst type training, can dramatically improve your cardiovascular fitness and fat-burning capabilities. Another major benefit of this approach is that it radically decreases the amount of time you spend exercising, while giving you even more benefits.

For example, intermittent sprinting produces high levels of chemical compounds called catecholamines, which allow more fat to be burned from under your skin within the exercising muscles. The resulting increase in fat oxidation increases weight loss. So, short bursts of activity done at a very high intensity can help you reach your optimal weight and level of fitness, in a shorter amount of time.

*Strength Training: Rounding out your exercise program with a 1-set strength training routine will ensure that you're really optimizing the possible health benefits of a regular exercise program.

You need enough repetitions to exhaust your muscles. The weight should be heavy enough that this can be done in fewer than 12 repetitions, yet light enough to do a minimum of four repetitions. It is also important NOT to exercise the same muscle groups every day. They need at least two days of rest to recover, repair and rebuild.

*Core Exercises: Your body has 29 core muscles located mostly in your back, abdomen and pelvis. This group of muscles provides the foundation for movement throughout your entire body, and strengthening them can help protect and support your back, make your spine and body less prone to injury and help you gain greater balance and stability.

Exercise programs like pilates and yoga are great for strengthening your core muscles, as are specific exercises you can learn from a personal trainer. Focusing on your breath and mindfulness along with increasing your flexibility is an important element of total fitness.

Is Staying Motivated an Issue for You?More than half of U.S. adults don’t get the recommended amount of exercise, and one out of four don’t exercise at all.

The most common reason why people say they don’t exercise -- A LACK OF TIME!

Unfortunately, not enough people are willing to arrange their schedules around exercise, and this is due to something much deeper than time management -- it’s due to psychological resistance.

No matter what reason you have for not exercising – feeling it’s too hard, getting bored with your routine, not knowing where to start – you can help yourself get into a more positive frame of mind. Further, instead of focusing on the negatives, like the work and the time it takes to stay active, focus on how great you’ll feel once exercise becomes a regular part of your life.

In case you weren’t aware, exercise does far more than just assist in weight loss. The following lists some of the many things exercise can do for your mind and body. Then, whenever you’re thinking of quitting, take a look.

*Improve your brainpower
*Lower your blood pressure
*Fight off a cold
*Manage arthritis
*Lower your risk of heart disease
*Cure insomnia
*Fight depression
*Lower your risk of diabetes and reverse pre-diabetes
*Build strong bones
*Lose weight
*Reduce your risk of cancer
*Boost your IQ and think better
*Relieve chronic knee pain
*Increase your energy levels
*Slow down your aging process

Irradiated Foods Exposed to Gamma Radiation

Irradiation leads to the formation of furan, which has been linked to liver toxicity, including carcinogenicity

Irradiated foods must be labeled with the statement "treated with radiation" or "treated by irradiation" and the international symbol for irradiation, the radura

Irradiated foods contain compounds called 2-alkylcyclobutanones (2-ACBs), which may promote tumor growth and colon cancer; they are found exclusively in irradiated foods

Irradiation is essentially a very effective medium for masking filthy conditions in slaughterhouses and food processing plants; You can avoid irradiation by choosing locally grown, organic foods as much as possible

Irradiated herbs, seasonings and spices are exposed to HALF A BILLION chest X-ray's worth of gamma radiation. This information is clearly publicized by the USDA and FDA.

The FDA presently supports the use of Cobalt-60 culled from nuclear reactors on all domestically produced conventional food.

The level of gamma-radiation used starts at 1 KiloGray -- equivalent to 16,700,000 chest x-rays -- and goes all the way up to 30KiloGray (500,000,000 chest x-rays or 10,000 times a human lethal dose).

According to Green Med Info:
"Despite the irresponsible promotion of this process as safe, food irradiation destroys much of the vitamin content of food, produces a number of toxic byproducts: formaldehyde, benzene, and formic acid, as well as unique radiolytic products, e.g. 2-alklycyclobutanoes, that have been demonstrated to be cytotoxic (damages cells), genotoxic (damages DNA), and carcinogenic (causes cancer) in test tube and animal studies."

You're probably well aware that certain foods, like milk and juices, at your grocery store are pasteurized -- a process that uses heat to kill off bacteria from your food, and in the process destroys nutrients and denatures the food. But you may not know that foods may also be irradiated -- a process that exposes your food to radiant energy, including gamma rays, electron beams and X-rays.

Irradiation was approved by the U.S. Food and Drug Administration (FDA) in 1963, and today is used on more than 40 food products dispersed throughout 37 countries. If this sounds a bit alarming to you, you are not alone.

After nuclear disasters like the Fukushima meltdown in Japan, radiation poisoning to food is one of the primary health concerns. So how is it that food processors can expose your food to radiation on purpose, in the name of food safety?

Are There Health Risks to Eating Irradiated Food? The FDA claims, "Irradiation is an important food safety tool in fighting food borne illness," noting that the sources and amounts of radiation applied to foods are not strong enough to cause the food to become radioactive. They also state that "food irradiation does not significantly change the nutrient content, flavor, or texture of food."

GreenMedInfo.com, states:
"The FDA presently supports and actively promotes the use of Cobalt-60 culled from Nuclear Reactors as a form of "electronic pasteurization" on all domestically produced conventional food.

The use of euphemisms like "food additive" and "pasteurization" to describe the process of blasting food with high levels of gamma-radiation cannot obviate the fact that the very same death-rays generated by thermonuclear warfare to destroy life are now being applied to food to "make it safer".

This is not a hypochondriac's rant, as we aren't talking here about small amounts of radiation. The level of gamma-radiation used starts at 1KiloGray (equivalent to 16,700,000 chest x-rays or 333 times a human lethal dose) and goes all the way up to 30KiloGray (500,000,000 chest x-rays or 10,000 times a human lethal dose)."

As you might suspect, exposing food to the equivalent of hundreds of millions of x-rays does not appear to be an innocuous act. Alternatively, evidence to date suggests it may be having a detrimental effect on the health of those who consume it.

A New Class of Food Contaminants
2-alkylcyclobutanones (2-ACBs) are radiolytic derivatives of triglycerides found exclusively in irradiated food. The compounds are generated proportionally to fat content of the food and the dose of absorbed radiation.

Research in animals suggests the compounds may promote tumor growth and colon cancer, and studies show 2-alkylcyclobutanones are able to cross the intestinal barrier, enter into the bloodstream, and be stored in the fat tissue of an animal. The compounds have also been shown to be cytotoxic and genotoxic, which means they may damage cells and DNA, respectively. Studies on human cells also revealed potential cancer-causing effects, with researchers concluding "this compound may be regarded as a possible risk factor for processes in colon carcinogenesis related to initiation and progression."

More Reasons to be Wary of Irradiation Needless to say, the research to date is raising major red flags that irradiation is NOT as safe as food safety officials would have you believe. In addition to the formation of potentially toxic 2-ACBs, irradiation leads to the formation of furan from ascorbic acid, fructose, sucrose, or glucose.

Furan in foods has been linked to liver toxicity, including carcinogenicity. Another study found that cats developed "mysterious" and "remarkable" severe neurological dysfunction, including movement disorders, vision loss and paralysis, after being fed a diet of irradiated foods during gestation. When they were taken off the irradiated foods, they slowly recovered. This is a major clue that irradiated foods deserve some serious regulatory scrutiny, but unfortunately they have already infiltrated the food system. And it's not as though this concerning evidence was just recently brought to light. One paper on potential dangers, prepared for the meeting of the Joint FAO/IAEA/WHO Expert Committee on Irradiated Food, dates back to 1969. The author stated: "irradiation can bring about chemical transformations in food and food components resulting in the formation of potential mutagens."

Does Irradiation Actually Mask Filthy Food Production?
The FDA is quick to state that "Irradiation is not a substitute for good sanitation and process control in meat and poultry plants. It is an added layer of safety." But it is, in essence, a tool to wipe out bacteria, parasites and other potential pathogens that linger in food. This means food manufacturers have an out of sorts. After all, they're going to nuke everything later anyway, so why go to the trouble of actually growing your food in sanitary conditions to begin with?

Irradiation is essentially a very effective medium for masking filthy conditions in slaughterhouses and food processing plants. The foundational solution to this problem lies in preventing contamination at the source -- on the farm, during processing and shipping, and so on -- not in wiping out pathogens later using questionable technological interventions like radiation!

There simply shouldn't be any need for irradiation, as there simply shouldn't be E. coli in your lettuce or Salmonella in your poultry in the first place.

So why is there?
Our "global food system," which encourages farming on a massive scale, poses steep problems for food safety. Not only can one batch of contaminated spinach or peppers easily sicken people across an entire country, but it's very difficult to trace a contaminated food back to its source and even harder to then pinpoint the source of the contamination.

Public health agencies like the FDA use the term "field-to-fork continuum" to describe the path any given food takes on the way to your plate, and during any of the following steps, contamination is possible: Open field production - Harvesting - Field packing - Greenhouse production - Packinghouse or field packing - Repacking and other distribution operations - Fresh-cut/value-added processing - Food service and retail - Consumer.

As you can see, the more steps your food goes through before it reaches your plate, the greater your chances of contamination becomes.

But again, the solution is not to subject your foods to radiation to make them "safe" they should be safe from the get-go, and this is one of the primary reasons why I encourage you to think long and hard about the sources of your food. If you are able to get your food directly from the field or after harvest, such as directly from a farmer or farmer's market, you knock out five potential operations that could expose your food to contamination, not to mention you'll have assurance the food has not been irradiated.

Do You Want to Avoid Irradiated Foods?
In the United States, the following foods may be irradiated:
Fresh meat and poultry (including whole or cut up birds, skinless poultry, pork chops, roasts, stew meat, liver, hamburgers, ground meat, and ground poultry), Wheat and wheat powder White potatoes, Many spices, Dry vegetable seasonings, Fresh shell eggs, Fresh produce.

Fortunately, the FDA currently requires that irradiated foods include labeling with the statement "treated with radiation" or "treated by irradiation" and the international symbol for irradiation, the radura:



However, there are exceptions:
Irradiated meat used in another product (such as sausage) does not have to contain the radura image on the package (it does have to list irradiated meat in the ingredients, though).

Restaurants are not required to disclose the use of irradiated foods. So be aware that any time you eat out, you have no way of knowing if your food has been irradiated.

You can also avoid irradiation by choosing locally grown, organic foods as much as possible. Certified organic foods may not be irradiated, and foods from a small, local farm are unlikely to be either. So, as I've said many times before, supporting the small farmers in your area and, as much as possible, getting your food from these types of high-quality, small-scale local sources is one of the simplest ways to access pure, unadulterated food.
