Have Your Own Brain Music To Help You?

Do you have your own specific soundtrack in your brain? Can music be used to change how you respond to stress and how you relax? Could you have your own Brain Music to help you be being productive and to relax you?

According to an article about research at the Department of Homeland Security, our brains all have their own soundtrack. This soundtrack varies between individuals.

The aim of the research is to improve the reactions and reflexes of first responders while at an incident, and also to help them relax and de-stress afterwards.

The program called “Brain Music” analyzes brain waves of study participants, and then makes two musical compositions, for each participant. One composition is designed for when under stress, needing to focus and be productive and has a “Mozart sound”. The other composition is for reducing stress and relaxing, and has more of Chopin sonata feel to it.

This music is initially going to be tested on firefighters.

If the Brain Music is found to be effective, then it could have all sorts of uses.

You could have Brain Music that helps with insomnia, winding down after a hard day at work (cheaper and better for you than a couple of beers?) and coping with pain and health problems. The Brain Music could also help you with deadlines at work, driving in heavy traffic and playing sports. Your life would have its own personal soundtrack.

Fructose May Be Worse For You Than Glucose

Does sweetening a product with fructose as compared to glucose make much of a difference? Or is a sugar calorie just a sugar calorie?

Previously there has been a post on this blog Fructose messes with appetite control. Now there is a study that suggests that consuming fructose may be worse for you than glucose.

A new study gave overweight volunteers either fructose-sweetened drinks or glucose-sweetened drinks for 10 weeks. The amount fructose or glucose in the drinks represented a quarter of their energy requirements.

Both groups gained weight, but those that were drinking fructose had several changes that were worse than those drinking glucose.

Those that got the fructose-sweetened drinks put on more belly fat than those that got the fructose-sweetened drinks.

There was an increase in the levels LDL particles (bad cholesterol), including small dense LDL particles, which are the worst type of these bad cholesterol particles, as well as a few other types of lipid particles, except triglycerides.

Additionally, the consumers of the fructose-sweetened drinks had increased fasting glucose, higher levels or insulin and were less insulin sensitive. High fasting glucose and being less insulin sensitive (insulin resistant) are hallmarks of the development of diabetes.

This study suggests that in those that are overweight, that eating or drinking much fructose may increase belly size (see the post Chronic inflammation results from belly (visceral) fat for information about why belly fat is bad), give a worse blood lipid profile and increase the risk of developing diabetes.

Though this is a small study, did not look at anybody who was not overweight, and was only for 10 weeks long, the fact that there were changes in 10 weeks make you think.

The bottom line is that eating and drinking less fructose-containing products is probably a good idea. There is not really any negative impact of consuming less fructose, and there may be a positive impact on health.

Dirty Marketing, Prevention Magazine, Wrinkle Creams

Do you know what forced continuation is? It is a marketing ploy that is used to catch the unwary and extract their money. It is easy to fall prey to this type of “dirty” marketing.

It happened to me, and I know how it works and usually read the small print. In doing this blog, and having websites related to health and aging, I like to keep up with what else is out there. Prevention magazine is a very popular magazine, so I decided to subscribe to it. I re-subscribed after the first year but then got bored with it, since it is pretty repetitious. So when I got renewal invoices I just ignored them . Yesterday I got a letter from a collection agency telling me I that the client (Prevention magazine) had not received payment for the subscription, and giving me “the opportunity to resolve this matter before it goes any further”.

I had not bothered to read the small print which currently says the following

“Your subscription will be automatically renewed at significant savings off the cover price, unless you tell us to stop. You authorize us to charge your credit card for your renewal subscription before your current subscription expires at the low renewal rate then in effect. If your credit card can’t be charged for any reason, or if you selected the Bill Me Later option, we will bill you directly instead. This service will continue each year until you tell us to stop. If you wish to cancel, call (800) 813-8070 or contact customer service at any time.”

This is known as forced continuation. To stop continually getting the product periodically forever, you have to physically cancel, usually by phone.

The company hopes you don’t notice. Some companies are very sneaky about where they put the small print.

A category of products that are really bad for forced continuation are wrinkle creams. Many of them have a free trial, if you just pay the shipping and handling. However, in the small print you will find that by getting the “free trial” you are agreeing to have the product shipped to you every month and your credit card will be billed every month. Beware of all those fake blogs, that tell you “how I improved my wrinkles” and have amazing before and after pictures.

Caveat emptor. Buyer beware.

How Vegetables Are Prepared Affects Antioxidant Power

When considering the amount of antioxidants in foods, the cooking method can increase or decrease the amount of oxidant power of a food.

Unfortunately there seems to be much disagreement about what is the best cooking method. Though there is general agreement that different fruits and vegetables react in different ways to the various cooking methods.

Part of the problem is that everybody seems to use their favorite method for measuring antioxidant power. The problem with antioxidants is that there is a range of them, with different structures and different mechanisms of action. So there can be very different methods for analysis.

However, it is clear that some vegetables have increased antioxidant power after cooking. Raw is not always best.

A recent study carried out in Spain, compared the effects of a number of different cooking methods on twenty vegetables.

The six cooking methods were boiling, pressure-cooking, baking, microwaving, griddling (hot pan without oil) and frying.

They found the following

• The highest antioxidant loss was observed in cauliflower after boiling and microwaving, peas after boiling, and zucchini after boiling and frying.
• Green beans, beets, and garlic were found to keep their antioxidant levels after most cooking treatments.
• The vegetables that increased their antioxidant levels after all cooking methods were green beans (except green beans after boiling), celery and carrots.

The researchers in this study suggest that water-based cooking methods most frequently resulted in losses. This is agreement with most, but not all, other studies that have suggested that for many vegetables, in particular brassicas such as broccoli, cabbage and cauliflower boiling is results in loss of some types of antioxidants.

It seems everything just gets more complicated. Do we have to cook all the components of a meal in different ways to get the most beenfit?

Staying slim will reduce global warming

What are the advantages of staying slim? Lower risk of heart disease? Diabetes? How about reducing global warming?

A new research paper lays out the arguments for why staying slim will reduce global warming. They point out the following;

Eating less means less food production is required. This means less fertilizer, less farm equipment, less transportation. The reduction in transportation could be significant in areas where the local land could feed the local population, meaning less transportation of food from far away. All of this would decrease green house gas emissions.

If everybody weighed less, this would mean less energy for transportation of humans too. The drop would be due to both less weight to transport (particularly significant for air transportation) and also lighter fitter people tend to drive less.

The researchers estimate that a lean population of 1 billion people would emit 1.0 GT (1,000 million tonnes) less carbon dioxide equivalents per year compared with a fat one.

Unfortunately the trend is the other way. We are all gaining weight. In the majority of countries in the world the average body mass index (BMI) is increasing.

So to save the planet, recycle, reuse and eat less.

Energy Drinks, Spit Don’t Swallow?

Want a boost? Have an energy drink. But, did you know that if you just swill one round your mouth and spit not swallow, that you get that boost in energy.

Energy drinks are everywhere. The supermarket has a big selection. Most of the energy drinks consumed contain some form of sugar and “energy ingredients” mainly caffeine.

There have been a number of well publicized studies that have shown that the some brands have little, to no, caffeine. However, since consumers seem to find all brands give them energy, it has been suggested that it is often the sugars that are responsible for the energy response.

Recently, it has also been shown that rinsing out your mouth with an energy drink and then spitting it out, not swallowing any, has the some effect as drinking the drink!

Why should just having the drink in your mouth have an effect? Previously it had been suggested that it was the rapid rush of calories that resulted in the energy effect.

However, recently it has been shown that just having calories in your mouth activates your brain! This activation can lead to improved athletic performance.

In a new study athletes were give one of three drinks. One contained glucose, one contained maltodextrin, a carbohydrate that we cannot taste, and the last one no carbohydrate, water. The taste of all three was adjusted with artificial sweetener so that they all tasted the same.

The athletes that were given drinks with carbohydrate, either glucose or maltodextrin, performed better than those given the water. Since the maltodextrin also had the effect, there must be carbohydrate receptors in our mouths that sense carbohydrate in addition to those sensing sweet.

MRI studies of brains showed that the glucose and maltodextrin triggered responses in the same part of the brain, but that there was not a similar response to artificial sweetener alone. This is good evidence that there are major effects are directly from the mouth to the brain. The drinks do not have to go into the tummy!

So, if you rinse, spit and don’t swallow energy drinks, you can get the benefits without the calories.

New Type Of High Blood Pressure Treatment

It is estimated that one in three adults have high blood pressure. Though current treatments are effective for many people, there are some whose blood pressure does not come down enough, even when they are on multiple drugs. Now there is news of a new type of high blood pressure treatment.

Unless you measure your blood pressure, generally, you have no idea of what your blood pressure actually is. It could be low, normal or high. It is really a good idea to measure it once in a while.

There a whole range of treatment options for high blood pressure, ranging from controlled breathing to one or more drugs. These treatments will reduce blood pressure for most people. However, there are some people who are resistant to treatment; their blood pressure will only drop slightly, with combination therapy such as a three different drugs, and stays well above the target range.

A small study now suggests an alternative type of treatment for lowering blood pressure. This new method used minimally invasive surgery.

Using a catheter (tube threaded into the body) they were given radiofrequency treatment in a specific area close to the kidney. This treatment destroyed certain nerves. The kidney is one of the major organs for controlling blood pressure. By inactivating certain nerves, and hence stopping some signals to the kidney, blood pressure will drop.

All the subjects in the study were on three blood pressure drugs, and still had systolic pressure (upper number) of 160 mm Hg or greater. Those that had the surgery had a big drop in blood pressure and this drop was maintained 12 months later. The study participants that did not have the surgery, on average, had slightly higher blood pressure after 12 months.

There were no problems for any of the patients that had the surgery. Catheters are commonly used for other techniques such as angioplasty.

This technique could reduce the number of people with heart failure, strokes, heart attacks and eye damage significantly. The use of this surgery could translate into many people not getting a reduced quality of life due to the consequences of uncontrolled high blood pressure, and huge healthcare savings. Hopefully the early findings are repeated in larger studies.

Lipoic Acid, Antioxidant, Triglycerides, And Diabetes

You have probably heard of lipoic acid, or alpha lipoic acid? It is found naturally in foods. Recently there has been interest in supplementation with lipoic acid for a number of conditions including diabetes. Most recently it has been suggested to lower triglycerides.

Lipoic acid and alpha lipoic acid are generally used interchangeably. The lipoic acid that is found in foods is alpha lipoic acid. It is found in both animals and plants and in is the cells of our bodies. It is essential for life.

Lipoic acid is required for correct functioning mitochondria (the powerhouses of cells) and has antioxidant properties. One property of lipoic acid is that it is able to interact with both reactive oxygen species (ROS) in both water (aqueous) and fatty environments. This potentially makes it very effective as an antioxidant.

Lipoic acid is thought to be helpful for diabetes (discussed below), Alzheimer’s and several other conditions. Now comes a demonstration that lipoic acid may lower triglycerides

One effect of lipoic acid is to increase the uptake of glucose into cells. It does this by mimicking insulin, which increases the uptake of glucose by a type of glucose receptor called glut4. This may be of benefit for those with type 2 diabetes or prediabetes. For many people increasing uptake of glucose into cells will help lower blood glucose. The studies with animal models of diabetes look promising, it remains to be seen if lipoic acid is helpful for human diabetes.

One of the effects of both type 1 and type 2 diabetes is that there is increased oxidative stress in the body. Since lipoic acid has antioxidant properties, it may also be useful in reducing some of the negative health consequences of diabetes. Again looking at animals with diabetes there is a benefit. One benefit is a reduction in peripheral neuropathy, which is damage to nerves in the body, caused by diabetes.

New research suggests that lipoic acid may reduce triglycerides. High triglycerides are a risk factor for cardiovascular disease and are often increased in diabetics. Triglycerides levels increase in diabetes due to lipoprotein lipase, the enzyme that degrades triglycerides, becoming less sensitive to insulin. (Reduced sensitivity to insulin, called insulin resistance, is a hallmark of type 2 diabetes.) Since lipoic acid is thought to act as an insulin mimetic for glucose uptake, perhaps it also works the same way for lipoprotein lipase as it does with glucose uptake by glut4.

Most foods have low levels of lipoic acid. However, it is not possible to eat enough food to get the amounts of lipoic acid used in research. Therefore, anyone who wants to significantly increase their lipoic acid intake will have to take supplements.

Do You Have Much Brown Fat?

On reading the question do you have much brown fat; you are probably thinking I really hope not. However, you should be thinking the reverse.

So why on earth would you hope to have some brown fat? We nearly all hope for less fat, and brown fat sounds pretty yucky.

When we are born we have quite a bit of brown fat, or as it is also known, brown adipose tissue. The main purpose of brown fat is to make heat. Newborn babies are not able to move much, have little surface body fat, usually not able to shiver and their nervous system is not fully developed. Therefore, newborns use brown fat to help keep them warm in cool conditions.

White fat, the “regular” fat, has two purposes, one is protection and cushioning, particularly of our organs, the other is to store energy.

Putting out heat means using lots of energy, which of course, is using lots of calories. So brown fat uses calories, whereas white fat stores calories.

It was thought until recently that as a baby developed it lost all its brown fat. However, it has been shown by activity and biopsy that most adults do have some brown fat. Not a lot, but some.

Now it has been shown that the brown fat is activated when somebody is in cool conditions for an hour or two. This makes sense when the body is cold, it tries to heat itself. One way this happens is by shivering. Shivering is using your muscles to move, which generates heat. Activating brown fat is another way to heat your body.

So, generally, who has the most brown fat? Thinner people tend to have more than fatter people – less of an insulating layer of white fat. Younger had more than older. Those with lower glucose levels. Women had more than men.

This raises some interesting questions. If you kept yourself slightly cold how many extra calories would you burn? Would it be enough for weight loss? Are people who live in cold climates or cold houses likely to be thinner? If you keep brown fat activated, will the amount you have increase?

Should we all turn down the thermostat and take a blanket off the bed?

Omega-3 Fatty Acids May Slow Cancer

Do you consume much omega-3 fatty acids? Eat cold water fish, take fish oil capsules, flax oil capsules or eat flax meal? Is so, you might be slowing the growth of any tumors (cancer) that you have.

First, a couple of days ago I had a post Should You Consume Less Fish or Fish Oil. This post talked about how the fish stocks have crashed and whole ecosystems will probably get wrecked. It was suggested that plant sources are the way to go. The post talked about how yeast are being engineered to produce high levels of omega-3 fatty acids (Marmite plus, anyone?) and there are algae supplements too. The next post was about camelina, a plant related to rapeseed (canola) which is an excellent source of omega-3’s. So if you are already are or thinking of consuming high levels of omega-3 fatty acids, think about plant sources. Flax meal is good, since it also has high levels of good types of fiber.

Omega-3 fatty acids have been suggested to have a number of benefits including lowering the level of inflammation and lowering triglycerides.

Now, new research suggests that DHA (docosahexanoic or docosahexaenoic acid), an omega-3 fatty acid, may slow the growth of solid tumors, and further, both increased the effectiveness of cisplatin, a chemotherapy drug, and reduced the side effects.

This is just one study. If it is confirmed in other cancer models it has another implication. None of us know when a tumor is growing inside us, until starts to affect our health or is discovered accidentally. Perhaps DHA could slow the growth of any as yet undiscovered tumors that we have. Hopefully this research is confirmed.
