Grocery Stores Central in Childhood Obesity

We recently read an article based on an initiative to make Philadelphia supermarkets healthier, in an attempt to reverse childhood obesity.

Obesity rates have more than quadrupled for children ages 6 to 11 and more than tripled for adolescents ages 12 to 19 in the past 40 years. Rates are more significant in the lower-income, multi-ethnic communities and neighborhoods - usually located in food deserts (areas with no easy access to healthy affordable food).

"If we don't reverse the epidemic, the current generation of young people could be the first generation in U.S. history to live sicker and die younger than their parents' generation," says the Philadelphia proposal.

Because full-service supermarkets and grocery stores offer large varieties of healthier foods compared with convenience stores, there is growing evidence that people who live more than a mile from a full-service grocery store are less likely to consume a healthy diet and more likely to be obese.

Almost 60% of shoppers say they spend most of their food-budget money in full-service grocery stores and over 90% of shoppers from households with children say they have shopped in a grocery store in the past 3 months (half the time accompanied by their children).

Supermarkets also help protect adolescents from becoming overweight. Additionally, there is a direct correlation between the presence of convenience stores and being overweight.

Conclusion: Grocery stores are "center stage" for combating and preventing childhood obesity.

Change Supermarket Design
Although, as mentioned above, there are advantages to having easy access to grocery stores, some experts believe they need to be rearranged. After all, remember that supermarkets are designed to sell inventory as fast, and in as large quantities as possible. They actually have ways of luring you into buying much more than what you've put on your shopping list - what you had planned.

Here are a few of the proposed changes for supermarkets:
The initiative proposes things like moving sodas and chips from the end of isles (highly visible and very easy to access) and removing sugary cereals from the bottom shelves where little kids can most easily see and grab them. Another proposed change is to place healthy and unhealthy items next to each other.

Why are these Changes Needed?
The following is a very powerful statement taken directly from the article:
"Self-checkout doesn't have the gauntlet of candy bars. Some industry consultants calculated that an average American woman could lose four pounds a year just going through self-checkout."

This is proof that people are lured into buying and consuming items they did not intend to buy. One of the references used for our "Scientific Reasoning Behind Drinking Diet Soda" says that certain foods are as addictive as some illegal drugs.

We agree that placing addictive items at arms' reach of kids, and enticing buyers is a huge factor in the current obesity trend seen across the world (not just the US). Changing displays and updating item locations can be a huge aid. It will be interesting to see how far this initiative gets... All of these changes affect the stores' bottom line.

We invite you to read the following two articles. They expose manufacturers and their use of food labels to make their products look healthier than they really are:

Fish Oils Could Help with Mood and Alcoholism

Researchers at the Indiana University School of Medicine found a potential therapeutic benefit from fish oil supplements "for treating alcohol abuse and psychiatric disorders."

Mood Control
The study was a multi-year study in which mice were given omega-3 fatty acids. In mice with bipolar disorder, "The fatty acid DHA, which is one of the main active ingredients in fish oil, 'normalized their behavior,' according to Alexander B. Niculescu, M.D., Ph.D., associate professor of psychiatry and the lead author of the study."

They found that these mice would stop being depressed and did not become "manic" when stressed - unlike bipolar mice which are usually highly depressed and become readily manic under stress.

Dr. Niculescu also said that "When [they] looked into their brains, using comprehensive gene expression studies, we were surprised to see that genes that are known targets of psychiatric medications were modulated and normalized by DHA." This is molecular proof that dietary omega-3 influences gene expression in the brain.

Alcohol Consumption Control
Researchers also found that mice given DHA showed a reduced desire for alcohol.

"'These bipolar mice, like some bipolar patients, love alcohol. The mice on DHA drank much less; it curtailed their alcohol abusive behavior,' he said, adding that this is a completely novel finding."

A separate experiment was conducted on alcohol-loving mice. The researchers saw similar results.

Conclusion
Dr. Niculescu said that he believes a diet rich in omega-3 fatty acids may help the prevention of certain disorders, and could also help with alcoholism.

Mexico's "Queso Fresco" has Antihypertensive Activity

A study was conducted by the Eastern Regional Research Center, Agricultural Research Service, US Department of Agriculture. They state that "Hispanic-style cheeses are one of the fastest growing varieties in the United States, making up approximately 2% of the total cheese production in this country. Queso Fresco is one of most popular Hispanic-style cheeses."

The Study
Proteins from 18 different "queso fresco" cheeses were analyzed for potential antihypertensive activity. 6 were Mexican-style "queso fresco," made from raw milk, 12 were made from pasteurized milk and did not utilize starter cultures.

Researchers were looking for the proteins' ability to inhibit the angiotensin-converting enzyme (ACE) - an enzyme that participates in vasoconstriction (narrowing of blood vessels).

Cheeses were aged, and proteins were extracted periodically.

The Results
All cheeses produced ACE-inhibiting proteins.

The 6 Mexican style "queso fresco" cheeses stood out, however - the proteins were found only a few days after being aged. The model cheeses, made from pasteurized milk, produced these same results "after 8 weeks of aging when they were no longer consumable."

Intense Exercise Better Than Endurance Training

A recent study identified "high intensity exercise [to be] more beneficial than traditional endurance training" for those concerned about their cardiovascular health.

The study
47 boys and 10 girls volunteered for the study. The kids were randomly assigned to two groups - the moderate intensity group and the high intensity group.

Both groups performed 3 exercise sessions a week for 7 weeks. The moderate intensity group was asked to jog, non-stop, for 20 minutes while the high intensity group was asked to run a series of 20m sprints in a period of 30 seconds.

By the end of the study the moderate intensity group had 420 minutes of exercise and the high intensity group had only done 63 minutes. The moderate intensity group had burned an approximate 4,410kcals while the high intensity group had only burned 907.2kcals.

The Results
"The results revealed that both groups demonstrated improved CVD risk factors. However, the total exercise time over seven weeks was six times higher for the MOD group compared to the HIT group. Thus, significant improvements in CVD risk factors in the HIT group occurred in only 15% of the total exercise time."

This states that the body benefits MOST from high intensity training - kids in the high intensity group had same results in less than a fifth of the time as the kids in the moderate intensity group. This suggests that, "brief, intense exercise is a time efficient means for improving CVD risk factors in adolescents."

Roxarsone, Poultry, and Your Health

News that Roxarsone will no longer be used in poultry hit the web today.

Roxarsone is a 67 year-old drug that has been administered to poultry to protect it against certain diseases. Pfizer (Roxarsone's manufacturer), along with the FDA, opted to stop giving the medication to poultry because the compound contains levels of organic arsenic that can convert into inorganic arsenic which is known to cause certain cancers.

It doesn't look like there will be a recall of any chicken. "FDA officials stress that the levels of inorganic arsenic detected were very low and that continuing to eat chicken as 3-Nitro is suspended from the market does not pose a health risk." And really... why should there be a recall? We've been eating this junk for decades.

Is There a Cover-up on the Way?
We're not advocates of conspiracies but we did find it odd that for the first time, the Medical News Today displays a 404 (page not found) error when following links from Google and Twitter.

Here are three screen shots (one of Google, one of the tweet, and one of the page).

Potassium-to-Sodium Ratio

Recent literary reviews suggest that salt balance may be key to preventing heart disease.

Literary Review
"Americans are consuming too much sodium and not enough potassium."

"This imbalance is taking a toll in the form of higher rates of heart disease and stroke, the first and third most deadly diseases in the U.S., respectively, according to the Centers for Disease Control and Prevention."

The article names some fruits and vegetables that are good potassium sources. The idea is that if you eat these foods you will increase your potassium intake, balancing your potassium-to-sodium ratio.

Why is this important? According to the article, recent scientific research suggests that it is low potassium-to-sodium ratio that damages the heart, and not necessarily a person's total sodium intake.

Experts Say You Should Keep Your Athletic Kids Away from Sports and Energy Drinks

Every child involved in sports will have a greater need of rehydration than kids who do not play sports.

A new report says that "there is nothing better than water for that."

Clinical Report
The clinical report, issued by AAP (American Academy of Pediatrics), says that "There is a lot of confusion about sports drinks and energy drinks, and adolescents are often unaware of the differences in these products. Some kids are drinking energy drinks - containing large amounts of caffeine - when their goal is simply to rehydrate after exercise. This means they are ingesting large amounts of caffeine and other stimulants, which can be dangerous."

The report then describes sports drinks and energy drinks.

  • "Sports Drinks - these contain carbohydrates, electrolytes, flavoring and minerals. They are supposed to replace electrolytes and water lost through sweating. Young athletes who are involved in vigorous and prolonged sports may benefit from sports drinks. However, in the majority of cases they are unnecessary."

  • "Energy Drinks - these contain stimulants, such as taurine, guarana and caffeine. Caffeine has been associated with several damaging effects on children, effects which may harm the child's cardiovascular and developing neurologic systems. Energy drinks are totally unsuitable for children and teenagers."

Important points to take home from the above descriptions are that sports drinks are usually unnecessary (we would venture to say ALWAYS unnecessary), and that "energy drinks are totally unsuitable for children and teenagers."

Remember that: "In many cases, it's hard to tell how much caffeine is in a product by looking at the label. Some cans or bottles of energy drinks can have more than 500 mg of caffeine, which is the equivalent of 14 cans of soda" and that: "The carbohydrates in sports drinks may contribute to overweight and obesity risk. There is also the problem of dental erosion."

VitaminWater
On August 5th of 2010 we discussed a Negative Article About VitaminWater on Well-known Newspaper. So no... Your kids should not be drinking VitaminWater either.

After all, did you know that Coca-Cola lawyers say that "no consumer could reasonably be misled into thinking vitaminwater was a healthy beverage." Meaning that there is no reason anyone should think VitaminWater is healthy.
