Remember when George Herbert Walker Bush, the 41st president of the United States, declared he didn’t like broccoli and declined to eat it?
“I do not like broccoli,” said Bush, who served as President from 1989 to 1993. “And I haven’t liked it since I was a little kid and my mother made me eat it. And I'm President of the United States and I'm not going to eat any more broccoli.”
Well, all the broccoli-haters out there need to come up with some different anti-broccoli strategies.
Mom was right all along. Broccoli, Brussels sprouts and other cruciferous vegetables in the Brassica family (such as kale, cabbage and collard greens) are good for you.
Especially broccoli and Brussels sprouts, which have anticancer effects and other health benefits, researchers say.
Researchers at the Ohio State University Comprehensive Cancer Center-Arthur G. James Cancer Hospital and Richard J. Solove Research Institute have discovered that a substance in broccoli and Brussels sprouts can block the proliferation of cancer cells.
The substance is indole-3-carbinol (I3C).
In research published June 29 in the journal Cancer Prevention Research, the scientists said they discovered a connection between I3C and a molecule called Cdc25A, essential for cell division and proliferation. The research showed that I3C "causes the destruction of that molecule and thereby blocks the growth of breast cancer cells."
Cdc25A, they said, occurs at abnormally high levels in cancers of the breast, prostate, liver, esophagus, endometrium and colon, and in non-Hodgkin lymphoma, and in other diseases such as Alzheimer’s.
“I3C can have striking effects on cancer cells,” said study leader Xianghong Zou, assistant professor of pathology at The Ohio State University Medical Center. A better understanding of this mechanism, he said, "may lead to the use of this dietary supplement as an effective and safe strategy for treating a variety of cancers and other human diseases associated with the overexpression of Cdc25A."

Grocery stores and farmers' markets need to stock more broccoli and Brussels sprouts this week.
So, how do you prepare these greens? Here are the traditional ways, ala the Betty Crocker cookbook:
Broccoli: For a pound and a half: Remove large leaves and ends of tough stalks. If thick, gash stem several times. Boil 10 to 15 minutes. Serve buttered, with salt and pepper. Vary with oregano and lemon juice, Hollandaise sauce, or grated cheese.
Brussel Sprouts: For a pound and a half: Remove discolored leaves and stem ends. Leave whole. Boil 8 to10 minutes. Serve buttered, with salt and pepper. Vary with garlic salt, basil, dill, caraway, savory or cumin.
The cookbook, Country Cooking…California Style, published by the California Farm Bureau Women, includes several recipes for broccoli and one for Brussels sprouts. After all, California grows more of these two vegetables than any other state in the country.
Here are two Country Cooking recipes:
3 heads broccoli, chopped
1/2 cup butter
4 tablespoons flour
1-1/2 teaspoons powdered chicken stock base
2 cups milk
2/3 cup water
6 tablespoons butter
2/3 package seasoned stuffing
2/3 cup walnuts, chopped
Heat oven to 350 degrees. Cook broccoli just under tender. Drain and put in flat 2-quart casserole. Melt 1/2 cup butter, blend in flour and cook gently over low heat. Add chicken stock base. Gradually add milk, cooking until smooth and thick; pour over broccoli. Heat water and 6 tablespoons butter until melted. Pour over stuffing mix and toss; add nuts. Top broccoli with stuffing. Bake 30 minutes at 350 degrees. The amount of water used with stuffing mix may have to be adjusted to make a moist combination. Serves 12.
Coastal Brussels Sprouts Piquant
3 cups Brussels sprouts
1/3 cup mayonnaise
1/4 cup water
2 teaspoons horseradish
2 tablespoons grated onion
1/2 cup bread crumbs
Preheat over to 375 degrees. Cook sprouts in rapidly boiling water until barely tender. Drain and transfer to shallow casserole. Combine mayonnaise, water, horseradish and onion. Pour over sprouts. Top with bread crumbs. Bake 20 minutes. Serves four.

School diet and exercise policies may not be ideal, but research shows that they provide a healthier environment than many children have during summer vacation.
The American Journal of Public Health reported in 2007 that weight gain spiked during the summer between kindergarten and first grade. The difference was especially large for black children, Hispanic children and children who were already overweight at the beginning of kindergarten.
"Instead of scheduled meals and snacks, children at home during summer break may have continuous access to unhealthy snacks,” said Carly Marino, the coordinator of the UC Cooperative Extension Children's Power Play! Campaign in Los Angeles County. “In place of recess, children may spend more time watching television and playing video games. It all adds up to more calories consumed and fewer burned."
Marino is working with the Boys & Girls Club of East Los Angeles to prevent local low-income children’s summer slump. They hosted a week-long program that included lessons on how much sugar is in soft drinks and how many fruits and vegetables to eat. The children participated in a fitness obstacle course and water games in the Boys & Girls Club swimming pool.
As a general rule, elementary school children should get 60 minutes of moderate to vigorous physical activity every day, which can be done throughout the day for at least 10 minutes at a time. They should eat two-and-a-half to five cups of fruits and vegetables every day.
"Parents can help their kids stay on track this summer by including more fruits and vegetables in meals and snacks, limiting screen time and being positive role models," Marino said. "One of the best ways for parents
to help kids get active and maintain healthy eating habits is by enrolling them into a summer activity program, which provides scheduled play and snacks, as well as a safe place for children to learn and grow while parents
The program in Los Angeles was part of the California state Champions for Change campaign. Champions for Change suggests families adopt three simple rules:
- Eat more fruits and vegetables.
- Be more active.
- Speak up for healthy changes.
Children should get 60 minutes a day of exercise.
Don't take any wooden nickels? When the new Oak Park Farmers' Market in Sacramento opened last month, organizers made sure to have wooden tokens ready for opening day. Farmers' selling at farmers' markets and flea markets all over California will gladly accept wooden nickels, plastic tokens, or paper "market dollars" this summer in exchange for good food.
The Stockton Farmers Market under the crosstown freeway is wide awake at 7 every Saturday morning all year round, crowded with farmers and shoppers conducting a brisk business in fresh local fruits and vegetables, fish, eggs, tofu, flowers and lots more, often talking four or five different languages but managing just fine to communicate with each other. Every Saturday, thousands of dollars of sales are transacted using bright green plastic tokens. The tokens are part of a program by farmers' markets throughout California to ensure that the markets are accessible to all Californians.
Paper food stamps haven't existed in California since 2004, but many people still use the old name, food stamp program, when they talk about what is now the Supplemental Nutrition Assistance Program (SNAP). As a result of high unemployment and hard times, one in eight Americans receives SNAP benefits to purchase food. SNAP benefits are now issued electronically, and SNAP recipients shop using electronic benefits transfer (EBT) cards, which work like debit cards.
Farmers market vendors usually don't have the electricity, phone lines and authorization from the USDA needed to accept EBT cards as payment, so farmers market managers need to set up scrip systems for customers to use the cards. A market staff person swipes the card using a state-issued wireless terminal and sells the customer tokens to shop with. At the end of the market day, market vendors exchange any tokens received that day for cash from the market staff.
This year, help is available to market managers and associations implementing and promoting EBT access at their markets and welcoming SNAP customers:
- First, markets need to apply to be a SNAP retailer
- The California Department of Social Services will provide a free wireless terminal to any California market authorized by USDA to operate an EBT/scrip system. Contact Dianne Padilla-Bates, (916) 654-1396, email@example.com
- The Ecology Center Farmers' Market EBT Project, partially funded by the California Department of Food and Agriculture, will help market managers and associations with free consultation, free tokens, with setting up staffing, accounting, vendor training and with building community partnerships and designing custom posters and flyers to promote the markets to SNAP customers.
- To encourage more markets to open their stalls to SNAP customers, the USDA has just released its own How-to Handbook for accepting EBT at farmers' markets
As the workshop speaker explained that school foods are contributing to the growing epidemic of obesity among children, I slumped in my chair and flashed back to high school. At the 10:20 a.m. break, I could be found standing in line at the high school snack bar ordering a chocolate milk shake and a bag of nacho cheese Doritos. Daily.
UC Berkeley professor Michael Pollan and others argue that farm policy is to blame for our corpulence. Many reference a 2002 USDA-ERS study that shows Americans ate 12 percent more (300 calories) in 2000 than we did in 1985, and point out that the federal government subsidizes common ingredients of snack foods -- corn, wheat, soybeans and rice -- making them cheaper and more available to consumers.
"Farm prices are a small share of retail prices so even if subsidies made farm prices lower and those were passed on, they would have little retail impact," Sumner told me. "Moreover, for some important products such as dairy and sugar, farm policies raise prices."
Policies are being made to steer us toward more healthful choices. For example, soda cannot be sold in California schools. Growing up, I had unlimited access to soda. As an adult, I eschew soda. It’s hard to say whether my beverage preference changed due to education or just being a finicky eater, but informing consumers can influence their food choices.
The new law mandating publishing calories on menus has had a modest effect on purchases, but over the course of a year, could prevent a person from gaining 4 to 8 pounds, said Gail Woodward-Lopez, co-director of the Center for Weight and Health at UC Berkeley.
Lucia Kaiser, UC Davis nutrition specialist, reports that low-income consumers will buy fresh fruits and vegetables if given an incentive. In a Los Angeles pilot project, mothers were given $40 to buy fruits and vegetables. The study found that 6 months later, the women continued to consume more fresh produce.
Virtually all children attending public schools are offered school lunches. Many California schools have begun farm-to-school programs, working with local farmers to offer students fresh salad bars. Past UC studies have shown that students given a choice of fresh fruits and vegetables will eat them.
“Uniting policy with education is the way to go,” says Woodward-Lopez.
Despite my steady diet of junk food as a youth, my weight didn’t expand into triple digits until my mid-30s. Now I exercise, avoid chips and shakes and eat lots of fresh fruit and vegetables, but have become fat. Whose fault is that?

On the McDonalds Happy Meals website, children can make themselves the star of a music video. Kids are challenged to send pastries soaring over as many toasters as possible on the Pop-Tarts website's "Daredevil Toaster Jump." Cheetos lets kids upload a picture or video of a Cheeto to have its website’s “state-of-the-art analyzer thingy” determine what it resembles.
These and other “advergames” can have a tremendous impact on children’s preferences and purchasing requests for unhealthy foods, according to Jennifer Culp, a UC Food Stamp Nutrition Education Program training coordinator.
Culp and Diana Cassady, associate professor of public health sciences at UC Davis, analyzed the restaurant, beverage and food websites advertised on the Cartoon Network and Nickelodeon weekday afternoons and Saturday mornings between August 2006 and March 2007. In all, the duo reviewed 19 websites, 290 Web pages and 247 advergames.
Close to one-third of the TV advertising that included websites was for food. Eighty-four percent of the food websites advertised included advergames, a blend of interactive animation, video content and advertising which promote corporate branding and products. On average, one nutrition or physical activity message appeared for every 45 brand identifiers.
"I was astounded by how often logos or actual food products were integrated into the games," Culp said.
Some games used candy or cereal as game pieces, while others would require special codes – available only by buying a specific product – to advance to higher game levels, she said.
The study concluded that government regulations are needed for food companies targeting youths and health professionals and parents should monitor food industry marketing practices.
