Arginine may have anti-diabetic effect

As FoodFacts.com reports on new findings regarding the increase in Type 2 diabetes in our population, we always keep in mind that almost 400 million people worldwide are living with chronic diabetes – 90% of whom are suffering from Type 2 diabetes which is largely lifestyle-related. Today we read promising new information regarding the effects of the amino acid arginine as it relates specifically to the treatment of this common form of the condition.

New experiments conducted by researchers from the University of Copenhagen show that the amino acid arginine — found in a wide variety of foods such as salmon, eggs and nuts — greatly improves the body’s ability to metabolise glucose. Arginine stimulates a hormone linked to the treatment of type 2 diabetes, and works just as well as several established drugs on the market. The research findings have just been published in the scientific journal Endocrinology.

In new experiments, researchers from the University of Copenhagen working in collaboration with a research group at the University of Cincinnati, USA, have demonstrated that the amino acid arginine improves glucose metabolism significantly in both lean (insulin-sensitive) and obese (insulin-resistant) mice.

“In fact, the amino acid is just as effective as several well-established drugs for type 2 diabetics,” says postdoc Christoffer Clemmensen. He has conducted the new experiments based at Faculty of Health and Medical Sciences, University of Copenhagen. He is currently conducting research at the Institute for Diabetes and Obesity at Helmholtz Zentrum München, the German Research Centre for Environmental Health in Munich.
To test the effect of the amino acid arginine, researchers subjected lean and obese animal models to a so-called glucose tolerance test, which measures the body’s ability to remove glucose from the blood over time.

“We have demonstrated that both lean and fat laboratory mice benefit considerably from arginine supplements. In fact, we improved glucose metabolism by as much as 40% in both groups. We can also see that arginine increases the body’s production of glucagon-like peptide-1 (GLP-1), an intestinal hormone which plays an important role in regulating appetite and glucose metabolism, and which is therefore used in numerous drugs for treating type 2 diabetes,” says Christoffer Clemmensen, and continues:
“You cannot, of course, cure diabetes by eating unlimited quantities of arginine-rich almonds and hazelnuts. However, our findings indicate that diet-based interventions with arginine-containing foods can have a positive effect on how the body processes the food we eat.”

The new findings provide optimism for better and more targeted drugs for treating type 2 diabetes; the outlook is long-term, but promising.

FoodFacts.com is always excited by the prospect that future treatments for Type 2 diabetes – and any other debilitating health condition – may actually become dietary in nature. Whole, fresh, natural foods contain the nutrients we need to help us maintain optimal health … and they may just prove to help our bodies in ways we are just beginning to realize.

Weekly Top 5

At Foodfacts.com we commonly receive requests for healthy snack suggestions, alternatives for different meals, etc. We know many of you share different views on organic, genetically modified foods, sugar, saturated fat, and many other nutrition-related topic areas, but we feel there are always a few items that stand-out in our database that many may find interesting, or even want to try.

This week’s top 5:

Blueberries
blueberry
There’s nothing better than picking fresh, ripe blueberries during the summer months. Full of antioxidants and phytochemicals, these berries are considered a “superfood” because of their healthy benefits when eaten. Research has shown that some benefits of eating blueberries include reduced risk of cancers, decreasing the conditions of aging; such as Alzheimer’s, and also preventative of Hepatitis C. Add them to your favorite pies, make them into jam, sprinkle them on your yogurt, drink them in juice form,
or eat them by the handful. They’re great for you!

1311643567_ce732f7e2cRed Bell Peppers
They’re slightly sweet, slightly tangy, and very crunchy. Bell peppers are a great source of vitamins and minerals, mixed in with a great amount of flavor. Known as the “meaty” pepper, this vegetable is commonly added to salads, stews, and also eaten raw. Which is great, because it contains a great amount of carotenoids such as alpha-carotene, beta-carotene, lycopene, lutein, cryptoxanthin and zeaxanthin. The bell pepper has been shown to reduce the risk of inflammation, which then helps to prevent various types of cancers.
salmon
Salmon
This fatty fish has been given much praise and attention for awhile now. Full of omega-3 fatty acids, salmon consumption creates great benefits. Improved cardiovascular function, reduced risk of heart disease, reduced inflammation, and some evidence suggests that omega-3 fats may prevent the progression of certain psychotic disorders in high-risk children and adolescents. However, some overlooked features of salmon include the amino acid and protein content, which also provides great health benefits. Some that have been researched are alleviated joint pain, and regulating collagen and minerals within the bone and tissue.
spelt
Spelt Bread
This grain has been around for centuries, and offers a variety of wonderful nutrients that other grains may not be able to provide. This is because it contains B2, a great amount of manganese, niacin, thiamin, and copper. Together, these nutrients are powerful against atherosclerosis, diabetes, migraine headaches, and other moderate to severe conditions. Use this grain to make breads, pasta, muffins, and any other meal you desire!
figs
Whole Wheat Fig Bars
Figs have been a staple in many households for years. Which is a good thing considering that they’re high in potassium, and have a good amount of vitamin C. These fig bars are not only organic, which is an added bonus for many, but they also contain whole wheat flour as their base. Another positive, there are no added sugars.

Will we be eating genetically modified Salmon soon?

GM Salmon
Foodfacts.com tries to stay updated with recent news pertaining to genetically modified organisms. Due to the continuing rise of GM crops, fish, and poultry, we believe it’s necessary to alert consumers of these issues because we’re not quite sure yet what the health implications are from consuming such products. Read the article below to learn more about GM salmon!

WASHINGTON — Members of Congress are pushing to stop the Food and Drug Administration from approving genetically engineered salmon, saying not enough is known about a fish they say could harm fishery businesses in coastal states.

It appeared last year that the FDA might approve the engineered salmon quickly. But the congressional pushback and a lack of action by the FDA could mean the fish won’t be on the nation’s dinner tables any time soon.

The fish, which grows twice as fast as the conventional variety, is engineered by AquaBounty, a Massachusetts-based company, but not yet allowed on the market. The company’s application has been pending for more than 15 years. If the agency approves it, it would be the first time the government allows such modified animals to be marketed for people to eat.

Congressional opposition to the engineered fish is led by members of the Alaska delegation. They see the modified salmon as a threat to the state’s wild salmon industry.

In June, the House adopted an amendment by Rep. Don Young, R-Alaska, to an agriculture spending bill that would prevent the FDA from spending any money on approving the fish. His amendment was approved by voice vote with no objections.

Sen. Lisa Murkowski, R-Alaska, said last week she will attempt to add the same amendment to the Senate version of the bill.

“It kind of gives me the heebie jeebies that we are messing with what Mother Nature did a pretty good job with in terms of a king salmon,” Murkowski said.

While Murkowski’s opposition is rooted in concern for her state’s fishing industry, other senators have expressed worries about potential food safety or environmental risks. More than a dozen senators have written the FDA with concern about the approval process and food safety and environmental risks. Bills to stop the salmon have been introduced in both chambers.

Ron Stotish, the chief executive of AquaBounty, said he was optimistic when the FDA decided to hold hearings on the company’s application. But a year later, he said, he is frustrated by the delay and has lost investors in his business.

“If you had asked me a year ago if we would be having this conversation, I would have said no,” he said.

The FDA is still in the process of completing their review, spokesman Doug Karas said, “although we cannot predict when that will be.”

Karas said the FDA is planning on releasing a review of potential environmental impacts of growing the salmon – and soliciting public comments on that review – before reaching a decision. That means a decision could be months or even years away.

In the hearings last year, FDA officials said the fish is as safe to eat as the traditional variety. But critics call the modified salmon a “frankenfish.” They say they are concerned it could cause human allergies and the eventual decimation of the wild salmon population if the engineered animals escape.

AquaBounty has maintained that the fish is safe and that there are several safeguards against environmental problems. The fish would be bred female and sterile, though a very small percentage might still be able to breed. The company said potential for escape is low. The FDA backed these assertions in documents released before these hearings last year.

Genetically engineered – or GE – animals are not clones, which the FDA has already said are safe to eat. Clones are copies of an animal. In GE animals, the DNA has been altered to produce a desirable characteristic. The process is common in plant foods like corn and soybeans.

In the case of the salmon, AquaBounty has added a growth hormone from a Chinook salmon that allows the fish to produce growth hormone all year long. The engineers were able to keep the hormone active by using another gene from an eel-like fish called an ocean pout that acts like an on switch for the hormone. Typical salmon produce the growth hormone only some of the time.

Stotish acknowledged that approval of AquaBounty’s product is likely more difficult because they are the first. Approval of the company’s application would open the door for a variety of other genetically engineered animals, including an “Enviropig” being developed in Canada that has less-polluting manure or cattle that are resistant to mad cow disease. Each would have to be individually approved by the FDA.

“Blocking us is the best way to block anything that would come behind us,” Stotish said.

Fish oil may not help to prevent depression afterall

Click here to get more information on Fish Oils at blog.foodfacts.com!
Brought to you by Foodfacts.com:

Many health articles have reported in recent months that fish oils, primarily omega-3 and omega-6 fatty acids, help to prevent depression in women. Before you go purchase a lifetime supply of fish oils, know that these research studies are constantly evolving. Though some may claim new dietary benefits one month, chances are those recommendations could change the next. Currently, researchers are still looking into the link between these fatty acids and depression. Also, they are continuing to look into fish oil consumption and diabetes in women. Make sure you conduct your own research or consult with a physician before initiating any supplementation.

Eating fish rich in omega-3 fatty acids doesn’t appear to stave off the blues in women, U.S. researchers have found.

Their study, published in the American Journal of Clinical Nutrition, adds to the conflicting evidence on the benefits of fish oil, which some research has hinted might help certain people with depression.

“We know that omega-3s are important in brain function,” study researcher Dr. Alberto Ascherio, a nutrition expert at the Harvard School of Public Health in Boston, told Reuters Health.

“We approached this work thinking that when it comes to preventing depression, it’s conceivable that you are what you eat,” he said.

But the researchers’ findings didn’t bear out that prediction.

The team followed nearly 55,000 nurses over 10 years. All the women, between 50 and 77 years old, were free of depression when the study began in 1996.

Over the next decade, five percent of them eventually developed clinical depression. But the risk was the same regardless of how much DHA and EPA — two omega-3 fatty acids — women got from eating fish.
b12-salmon-lg1
Fish rich in omega-3s include salmon, trout, sardines and herring.

The researchers did find preliminary signs that a plant-based omega-3 called alpha-linolenic acid could play a role in mood.

For every increase of half a gram in daily intake of the substance –common in walnuts and canola oil, for instance — there was an 18-percent reduction in the risk of depression.

A study like the current one can’t prove cause-and-effect, and Ascherio said the area needs further research before any recommendations can be made.

His team also examined omega-6 fatty acids, but was unable to come up with conclusive findings on its impact on depression. Omega-6s are found in refined vegetable oils and are ubiquitous in snack foods, sweets and fast foods.

Depression strikes twice as many women as men, with one in five U.S. women experiencing the problem at some point.

Dr. Teodore Postolache, who directs the mood and anxiety program at the University of Maryland School of Medicine in Baltimore, told Reuters Health he is not yet ready to give up on fish oil.

“There are inherent limitations on studies about depression, including determining with certainty what exactly depression is for patients,” Postolache said.

Using data from nurses, for example, can skew results because nurses are more educated in matters of health and diet than the general population.

“If groups who may have underlying deficits in fish oil were studied, like lower socioeconomic groups, we might have seen a more powerful effect of the omega-3s in preventing depression,” he said.

He also noted that the study excluded women who had previous episodes of depression, although this group is one of “the most important targets for intervention because they are at high risk for a repeat episode.”

He called for more research on animals and in broader swaths of the population.
