Indiana Business Journal reports that the proteins from genetically modified crops exhibiting in Indiana waterways.
According to the Journal, the University of Notre Dame and Loyola University looked at 217 streams, ditches and drains near Indiana cornfields and found to be genetically modified (GM) bug-killing protein in 50 of them.
Proteins are genetically modified maize and other crops that are designed to produce their own pesticide when insects bite them, but when the farmers mow the fields, the residue remains from crushed plants – and it is to find their way into waterways.
"Protein made the runoff to surface water and leaves and stems, sometimes wash to streams," said Journal. "And protein 1350. the investigation was carried out six months after the harvest. "
Paper, published in the Proceedings of the National Academy of Sciences, says, it is not known whether the trace levels of proteins is a threat to aquatic animals in the water.
But either way – it is still married, and it is a poison that was in 85 percent of THE U.S. corn crop last year.
I've discussed the variables that can boost or hinder the benefits of your exercise routine in a number of previous articles, and I'll summarize them again below, but this study is unique in that it shows how your choice of cool-down routine can affect your post-exercise appetite.
Jumping into the pool after strenuous exercise can feel heavenly, but according to these preliminary findings, you may want to reconsider taking that dip if you're trying to lose weight.
The study was limited to 10 participants, so it may be premature to draw concrete conclusions. But if you're trying to shed a few pounds, these recommendations may be worth considering.
The participants were evaluated three times. Each 40-minute run was followed by one of three different 20-minute cool-downs:
Immersion in cold water (59 degrees Fahrenheit) Immersion in tepid water (91 degrees Fahrenheit) No immersion; sitting restingAfter each test, they were served a buffet breakfast and allowed to eat as much as they wanted.
Blood samples were collected to evaluate blood glucose, lactate, and the appetite-regulating hormones leptin and ghrelin.
Interestingly, after water immersion, the subjects:
Consumed an average of 80 to 108 more calories Consumed more carbs and protein Had reduced leptin levels Had increased ghrelin levelsLeptin plays a role in decreasing your appetite while ghrelin tends to increase it, so the changes in both of these hormones post-water immersion are indications of increased appetite, or reduced satiety.
Granted, more research is needed to confirm these findings, and it's possible that cold water immersion causes other metabolic changes that may counteract the slight increase in calorie consumption...
Not sure how I will apply results of this research personally though. In the summer months when I do my Peak 8 exercises I am drenched in sweat and typically find it very relaxing to jump in my in-ground outdoor pool. Since I really don't need to lose any weight, I will likely continue the practice as I find it refreshing. I will not even have the choice though until next May.
Aside from abstaining from a dip in the pool, there are a number of other pre- and post-exercise strategies you may want to keep in mind in order to boost your weight loss potential and optimize the health benefits of exercise.
Remember, exercise changes your biochemistry, and you can aid or hinder these beneficial changes, depending on what you chose to eat before and directly after exercise.
Let's review:
You may have heard that exercising on an empty stomach will help burn more fat, and there seems to be some truth to that, although it might not be appropriate for everyone.
Exercising vigorously when you're blood sugar is low could lead to dizziness and poor performance, and exercising while hungry can also lead to overeating afterwards.
Personally, I believe the best approach is to use some common sense and listen to your body. For example, if you feel weak or nauseous while exercising on an empty stomach, you may want to at least eat a small meal before exercising.
That said, the reason why fasting before exercise seems to work is because the fat burning processes in your body are controlled by your sympathetic nervous system (SNS). The SNS is inherently activated by exercise and lack of food. The combination of fasting and exercising maximizes the impact of cellular factors and catalysts (cyclic AMP and AMP Kinases), which force the breakdown of fat and glycogen for energy.
So, when you exercise on an empty stomach, you're actually forcing your body to burn fat.
However, as I just mentioned, fasting prior to exercise can reduce your performance. Fortunately, there is a better, and probably more efficient, way to boost fat burning without fasting.
A recent study published in the journal Medicine and Science in Sports & Exercise found that consuming 20 grams of whey protein 30 minutes before resistance training can boost your body's metabolism for as much as 24 hours after your workout.
It appears as though the amino acids found in high quality whey protein activate certain cellular mechanisms (mTORC-1), which in turn promote muscle protein synthesis, boost thyroid function, and also protect against declining testosterone levels after exercise.
In practical terms, consuming 20 grams of whey protein before exercise and another serving afterward will most likely yield the double benefit of increasing both fat burning and muscle build-up at the same time.
One of the worst foods you can eat prior to exercising is carbohydrates, as carbs will inhibit the SNS and reduce the fat burning effect of your exercise. Instead, this type of meal will activate your parasympathetic nervous system (PSNS), which promotes energy storage—the complete opposite of what you're aiming for.
Personally I do strength training three times a week and will typically consume a whey protein meal one hour before, one hour after, and three hours after, to provide the fuel for muscle growth. This is not as necessary for non-strength training exercises, however.
So, fasting, or even better, consuming high quality whey protein prior to exercise can boost fat burning. But equally important is what you do afterwards.
Again we find that sugar is at the bottom of the list.
In fact, consuming sugar (including starchy carbs that convert to sugar, and sugary energy drinks) within two hours of high intensity Peak 8 exercises will negatively affect your:
Insulin sensitivity, and Human growth hormone (HGH) productionBoth of these factors are very important for optimal health and longevity.
Impaired insulin sensitivity (insulin resistance) is the underlying cause of type 2 diabetes and a significant risk factor for other chronic diseases such as heart disease.
Meanwhile, maintaining your HGH levels (which tend to drop off after the age of 35) will help keep your body strong and your health robust.
The beneficial impact of a low-carb post-exercise meal on your insulin sensitivity was recently confirmed by a study published in the Journal of Applied Physiology. And hghmagazine.com clearly explains how consuming sugar/fructose, including that from fruit juices, within this two-hour window will decimate your natural HGH production:
"A high sugar meal after working out, or even a recovery drink (containing high sugar) after working out, will stop the benefits of exercise induced HGH. You can work out for hours, then eat a high sugar candy bar or have a high sugar energy drink, and this will shut down the synergistic benefits of HGH.
… If you miss reaching HGH release during working out, you will still receive the calorie burning benefit from the workout. However, you'll miss the HGH "synergy bonus" of enhanced fat burning for two hours after working out.
This is an extremely important fact to remember if you want to cut body fat and shed a few pounds.
So, to further reduce body fat while enhancing your insulin sensitivity and promoting HGH production, you'll want to eat a low-carbohydrate meal within that two-hour window.
One of the explanations for why a low-carb meal after exercise works is because carbs prevent the production of the hormone somatostatin. One of the primary purposes of this hormone is to inhibit the production of human growth hormone. So, by reducing somatostatin, you're not hindering HGH production.
Fitness expert Phil Campbell further explains how you can maximize your HGH production by limiting sugar intake for two hours post exercise, in this article on HowToBeFit.com.
Since I've just discussed HGH, I want to remind you that there is only ONE specific type of exercise that promotes the production of HGH in your body, and that is high-intensity interval training such as Peak 8.
Virtually all exercises -- certainly most conventional cardio or standard aerobics -- fail miserably when it comes to increasing growth hormone. Peak 8 exercises, however, are proven to boost natural HGH production.
Peak 8 type exercises can also dramatically improve your cardiovascular fitness and fat-burning capabilities in a fraction of the time. For more in-depth information about Peak 8 exercises, please see this previous article, as it is very important to perform these exercises properly.
Clearly, if you decide to use the only type of exercise that will increase growth hormone, then it would be a shame to wipe out this great fantastic benefit with foolish food choices like sugar/fructose/carbs.
Now, there is a minute group of elite and professional athletes who are actively competing and therefore less concerned with increasing growth hormone than with performance. For these athletes, consuming some carbs, preferably dextrose-based, during the two-hour recovery phase is probably a good idea in order to improve their recovery time.
But for the average person, forfeiting the benefits of HGH is both unnecessary and unwise.
In 1980, paid for them in the lowest income bracket 0,1% (one-tenth of one percent) of the nation's income tax. Those in the highest income bracket paid 64.8 percent of the Bill.
Suppose the nation income tax bill for the 1980 was $ 100. the whole group of those who earned at least the amount of income contributed $ 1 on $ 100 owed, while the highest paid workers picked up nearly $ 65 or $ 100.
2005, the lowest paid workers contributed less than nothing $ 100 tax bill and the Group on the other end of the spectrum paid approximately $ 86 of Bill.
In the case of it sounds fair enough ', where the income disparity of the two groups, let us look at it a different way.
By combining the three groups of citizens makes the least amount of income in 1980, which was 60 percent of the tax payer population, we see that this 60 percent – around half the tax-paying public – picked up only 15.1 per cent of the Bill.
The two highest wage-earning groups, which account for 40 percent of the taxpayers, picked up the remaining 85 percent of the Bill.
Now let us look at 2005. the lowest three groups kick in only 0.6 percent of the tax bill, while the two highest groups pay approximately 99 percent of the Bill.
It was 2005. it is now, by 2010, and the obvious question is, how can the upper income-earning groups, which are also the groups provides employment, production and welfare in this country, continue to afford this trend?
Frequent readers of my newsletter is not foreign for the tanks that, when a culture moves away from a traditional natural diet, diseases such as obesity, diabetes, hypertension, heart disease and cancer, inevitably seem to follow.
For review, I will list some properties to consider typical of the Western diet:
When you read about this list or drag, is it any wonder that 70 percent of Americans are overweight or obese?
It does not take much of a leap of imagination to come to the conclusion that the typical Western diet really only benefits large companies producing cheap food.
This is not a new idea, but Michael Pollan raises several interesting points about why you are led to believe that the food in their supermarkets are "healthy", when the result of eating these foods would seem to indicate otherwise.
Pollan calls on our Western food ideology "nutritionalism", which he defines as believing that nutrients are the most important component in food, and because the nutrients are invisible and not well understood, we must "experts" to tell us which foods are good.
Pollan argues that when we accept this ideology that "experts" tell us what is healthy, instead of eating whole, natural foods, as they exist in nature, are we destined for believing everything food manufactures tell us.
Why is this bad?
Because the largest employer of the "experts" is the food industry for yourself!
Today, it seems the same each item on your supermarket shelf "promotes good health"--you see claims on cereal boxes full of processed cereals and sugar, low fat desserts and snack foods filled with sugar and countless other products, all argue one so-called health advantage "discovered" by "experts".
The problem is to tell you the food producers only one side of the story!
Food manufacturers will tell, one ingredient in the product is "healthy", while ignoring all the other ingredients, not there!For example, according to Pollan has one yogurt that "experts" claim to be good for your digestive health Ounce for Ounce more sugar than Coca-Cola!
Study after study links sugar to a host of negative health consequences, but you can never find this information on the front page of yoghurt packaging.
When weighing the benefits versus the costs of any food, Michael Pollan has more suggestions can help you choose foods that are really good for your health:
Do not Eat anything your great-grandmother wouldn't recognize as food to avoid foods that never rot eat food so close to their natural state as possible
What scientists really know the nutrition and nutrients?
Not much, it strikes.
According to Pollan, is our current understanding of nutrients on as advanced as the art of surgery was in the middle ages. [citation needed] he claims, and rightfully so, in my opinion, that take individual nutritional components out of food and a synthesizing them not always leads to good results.
Rather than rely on the "experts", which in many cases just paid shrills to the food industry, is a much better alternative to eat a balanced diet filled with whole, natural foods, and avoid possible pitfalls Western diet.
In other words, eating a carrot, not a beta carotene pill!
Eat a balanced diet full of whole, natural foods is still the best way to promote good health. [citation needed] This is backed up by traditional communities around the world eat only food sources found near nature that displays none of the typical diseases found in the Western society eat diet.
By the way, it is a myth to eat healthy, natural foods are prohibitively expensive. Actually need to eat a healthy organic diet does not cost much more than a diet filled with processed foods and junk food.
Tips on which foods you need to buy organic, and which ones are worth the extra cost, please see this earlier article.
It is true that shopping in shops, trendy food can easily cost you your entire paycheck, but takes advantage of the sales on the healthy items and clipping coupons, as well as looking for fresh, locally grown food at a farmers ' market or in a CSA can all add up to big savings on your food bill.
Prepared foods can cost up to twice the unprepared bliksem p. ... versions, then buy the entire food, which you can do in the meals, rather than the prepared foods in a box can actually lead to big savings. And if you plan your meals ahead of time, you can get exactly what you want, when you need it, and to prevent yourself from buying too much and wasting some of it when things go bad.
If you still do not buy the idea that your family can afford to eat healthily, take a look at this breakdown of how your family can eat organic food at the same price as treated them.
And, of course, there are even greater, indirect savings that come with the whole eating food.
Consider, for example, the difference in the health care needs, between those who eat the whole foods, and those who eat processed and the factory farmed food containing MSG, carcinogenic or nerve poisons such as pesticides, trans-fats, enormous quantities of sugar, and artificial synthetic and friendly.
What little you might have to save right now by purchasing processed food, you'll end up spending many times over when your health fails.
