Two review articles, one published by the American Jounral of clinical Nutrition, and another by the London School of Hygene and Topical Medicine concluded that a review of literature from over the past 50 years shows no difference in health outcomes between organic and conventionally produced food.
The review concluded that the studies which showed health benefits to organic eating only focused on short-term benefits like antioxidant activity rather than long-term health outcomes. In general, the antioxidants studies did not find any differences between organic and conventional foods. The studies were also limited in scale have small sample groups and lasting over a short period of time. The US based review found that there was no difference in nutrient content between organic and conventional foods.
The reviews, however, are completely focused on pure evidence-based outcome that show biologically measurable changes. In this way, they are limited and cannot account for the social benefits of locally produced good and their benefit they may have on other areas of the environment. It also did not address possible consequence of eliminating pesticide usage on farm workers and other side products of organically grown food. In this way, their definition of "health" is extremely narrow and does not consider more broad yet equally important aspects.
Nutritional quality of organic foods: a systematic review

Increases in soda consumption are the most correlated with increases in obesity rates. What's more, this habit has also increased diabetes and cardiovascular disease rates among Americans.
The goal of this tax is to reduce the gallon-of-soda-a-week habit that the average American has, however CocaCola and PepsiCo have strong lobbyists that are working to reduce the tax or do away with it all together.
I think its about time we start taxing soda, because its negative effects are clear and disproportionately affect the poor. Considering all of the behavioral campaigns that have attempted to curve soda consumption, we now need something more substantial to lessen the consumption and effects of this sugary drink.

ScienceDaily (May 7, 2010) — Using herbicides to sterilize rather than to kill weedy grasses might be a more economical and environmentally sound weed control strategy, according to a study by Agricultural Research Service (ARS) scientists and a cooperator.
Rangeland ecologist Matt Rinella at the ARS Fort Keogh Livestock and Range Research Laboratory in Miles City, Mont., conducted the study with colleagues at Miles City and Robert Masters with Dow AgroSciences LLC, in Indianapolis, Ind.
Exotic annual grasses such as Japanese brome, cheatgrass and medusahead are harming millions of acres of grassland in the western United States. Currently, the herbicides used to control these invasive grasses also sometimes damage desirable perennial grasses.
In contrast, when used properly, growth regulators typically do not greatly harm desirable perennial grasses. Growth regulator herbicides are used to control broadleaf weeds in wheat and other crop grasses, as well as on rangelands. Rinella and his colleagues knew that when dicamba and other growth regulator herbicides were applied to cereal crops late in their growth stage, just before seed formation, the plants produced far fewer seeds.
The scientists decided to see if these herbicides had the same harmful late-stage application effects on the invasive weed Japanese brome. In greenhouse experiments, they tested dicamba (Banvel/Clarity), 2,4-D, and picloram (Tordon) at typically used rates. They found that picloram reduced seed production nearly 100 percent when applied at the late growth stage of the weed. Dicamba was slightly less effective, but still nearly eliminated all seed production, while 2,4-D was much less effective.
Since annual grass seeds only survive in soil a year or two, it should only take one to three years of herbicide treatment at the right growth stage to greatly reduce the soil seed bank of annual weedy grasses without harming perennial grasses.
Rinella has recently finished field tests that support the greenhouse experiment results. He also tested the herbicide aminopyralid (Milestone) and found it was as effective as picloram. Next he will test much lower doses of the herbicides in an attempt to lower costs and reduce non-target damage to broadleaf plants.
The research was published in the journal Invasive Plant Science and Management.

A New York Times article this week highlights the increasing popularity of vertical gardens. This trend began in 1988 when French botanist Patrick Blanc intended to create a garden without dirt. Now urbanites are adopting this method of vertical gardens to make their city living spaces greener.
Even though vertical gardens allow city dwellers to develop their green thumb without having to worry about land space, this system of garden seems to take up a lot more resources than conventional gardening. In short, those who want to grow a vertical garden must recreate the outdoors within their confines of their walls. This includes, irrigation, humidity, and lighting, which ultimately leads to thousands of dollars in investment for a 12 by 12 foot wall of green.
Although vertical gardens are a good idea in theory, it is not practical, affordable or ecologically friendly in practice.

5 ways to make eating organic foods affordable
7:00 am April 29, 2010, by Rana Cash
Chemically-treated produce shipped cross-country happens to be affordable. For families on a budget, buying organically grown local fruit and vegetables is good in theory but in reality, these goods aren’t always priced low enough to make the decision easy.
“If it’s certified organic, it might be a little bit more because of supply and demand and because of the amount of work that goes into it and the quality of the product,” said Michael Wall of Georgia Organics.
It’s not a lost cause, though. Preferring to prepare more wholesome ingredients doesn’t mean you have to be rich. There are ways to buy and eat reasonably-priced organic goods.
– Grow your own: This is the best time of year to plant summer vegetables like squash, as well as potatoes, tomatoes, lettuces and more. Seed sales have skyrocketed as backyard gardeners have put their hands in soil.
– Wholesome Wave Foundation: Started to benefit low income households, Wholesome Wave doubles the cash value of purchases made with federal food stamps and WIC. So $2 gets you $4 worth of groceries. The East Atlanta Village Farmers Market, Morningside Farmers Market and the On-Site Market at Truly Living Well Urban Farm are all participants in the program.
“It’s a great safety net for Georgia’s most impoverished,” Wall said. “Often, they have the least amount of access to fresh vegetables…It’s an economic incentive to buy fresh, wholesome food.”
– Join a Community Supported Agriculture group: Commonly known as CSAs, a mixed box of produce is brought to you (either at central locations or delivery) each week. While not cheaper than what you’ll find at the average grocery store, it is less expensive than high-end stores like Whole Foods or Harry’s.
Charlotte Swancy from Riverview Farms went on a comparison shopping trip recently and spent about $8 more at Whole Foods than a CSA customer of her farm would pay for the same products. Patrica Gladney of Farmers Fresh CSA said co-ops, in which farms work together to provide even more variety year-round, said their prices are comparable as well. At Lynn Pugh’s Cane Creek Farm, customers can also pick all of the herbs they want.
“It can be cost effective if you eat everything you get and you cook,” Pugh said.
– Work-share programs: You’ve seen the signs that read, ‘Will Work For Food.’ In this case, the workers mean it. Volunteer on a farm and in exchange, get a box of the food they sell.
– Community Gardens: Neighbors are helping neighbors, banning together to grow community gardens.
“You know your food is fresh; it hasn’t traveled great distances or come from another country,” Swancy said. “And you’re supporting local farmers.”

Public school lunches in the United States are known for being unhealthy, but do they pose a national security risk? A recent report released by an officers' group, Mission: Readiness, has declared the lunches we feed our children just that: unsafe for the country's security. Around 27% of American youth aged 17-24 are too overweight to join our armed forces, making it the leading medical reason that recruits are rejected from the military. While military officials recognize that the rejection of these young people has not yet affected recruitment goals, they warn that it may make a bigger difference in the future. A major contributor to the problem is the National School Lunch Program, which provides funding for lunches to schools across the country. The nutritional standards for these lunches have come under fire many times throughout history. The school lunch bill is currently awaiting Senate vote, which would provide $4.5 billion more over ten years for nutrition programs in schools.

With the the growing popularity of farmer's markets, commercial growers are trying to cash in by bringing their goods to farmer's markets. This is diluting the quality of products available at farmer's markets, so it is important to know who you are buying from.
- Read certificates/banners displayed by each vendor
- Talk to the manager of the farmer's market
- Have personal contact with the growers
The article was published in Southern California, and I haven't noticed any of these commercial growers at the Palo Alto farmer's market, but be on the lookout for them.
(Also, I have done quite a bit of research on organic foods and recall that some growers actually forgo getting certified by the USDA due to the cost and the process. It is a hassle for some small growers and not worth their time and effort. So it is important to talk to the vendors, because their produce might actually be grown organically even if they don't have the official certification. Another interesting fact is that some growers also don't get certified because they think the guidelines for organic farming are too relaxed and are becoming even more so with time. Here are some responses from growers themselves regarding Local Certified Organic vs. Local Uncertified Organic)

Santa Clara County has decided to ban toys from accompanying meals if they do not meet certain nutritional standards. The driving idea behind this new law is to disassociate toys from the high fat, high caloric meals for children.
It was interesting that the McDonald's spokesperson stated that the happy meal provided "important nutrients that children need." I know that when I was a child I (unsuccessfully) begged my parents for Happy Meals *just* for the toys-- but my parents knew I could get more nutrients from home-made meals without the calories, sodium or fat.
I hope this is a new wave that will start to be implemented in other counties.

WE MADE THE LOS ANGELES TIMES!

As an Asian American woman interested in journalism, I have always actively followed Lisa Ling's career. My favorite piece of hers was a documentary done on shark finning in 2008. This practice, most common in Asian countries, entails fishermen cutting the fins of sharks and leaving them in the ocean to die. Besides causing a steep decline in the shark population, shark finning is also detrimental to our ecosystem and the ocean's food chain. In the past two years since seeing the film, I haven't put much thought into the issue. This class has sparked me to look into the progress we've made (or haven't) on regulating the wasteful killing of animals for an expensive soup.
A KHON2 article I've linked to below explains the current ban on shark finning in US waters. The difficulty with this is, fishermen must be caught in the act. Otherwise, they can simply say they caught the fins in another country's waters. There is a current bill on the Senate floor proposing that the possession of shark fins be banned. This would make it extremely difficult to even make shark fin soup in the United States, as cooking or selling shark fins would be illegal. We will have to wait to see the fate of this bill.

This is an interesting article about the waste built into the food distribution system and the lack of economic incentives for solving the problem. With millions of people having a difficult time making ends meet, it seems an injustice that so many grocery stores would be throwing away such a massive volume of food. The article does mention that the need for more food donation has to be balanced with the risk of donating contaminated food that could injure or kill many needy families. One easy way to lighten up some of the food need would be to give tax breaks to Mom and Pop restaurants that donate extra food through established program that links food service donors with hunger relief agencies. Right now most of the restaurants that donate food are big franchises like pizza hut and chipotle because these "C Corporations" currently receive tax donations for doing so.

California Rural Legal Assistance and other organizations are doing substantial work to fight what's in "Harvest of Shame," including monitoring water and shade where government enforcement agencies don't.
April 3rd: "California Rural Legal Assistance along with the Law Offices of Michael Freund have reached a settlement worth $135,000 for ten farm workers who filed a lawsuit against a Central Valley orchard owner after they were exposed to pesticide drift. While working in an adjacent field, the farm workers were exposed to a dangerous pesticide by the neighboring orchard owner that caused symptoms including vomiting, nausea, skin irritation and difficulty breathing."
