The issue is helping folk to want to make healthier food choices even on a food stamp budget.

Roberto A. Ferdman of the Washington Post wrote in the article, The stark difference between what poor babies and rich babies eat:
The difference between what the rich and poor eat in America begins long before a baby can walk, or even crawl.
A team of researchers at the University at Buffalo School of Medicine and Biomedical Sciences found considerable differences in the solid foods babies from different socioeconomic classes were being fed. Specifically, diets high in sugar and fat were found to be associated with less educated mothers and poorer households, while diets that more closely followed infant feeding guidelines were linked to higher education and bigger bank accounts.
“We found that differences in dietary habits start very early,” said Xiaozhong Wen, the study’s lead author.
The researchers used data from the Infant Feeding Practices study, an in depth look at baby eating habits, which tracked the diets of more than 1,500 infants up until age one, and documented which of 18 different food types—including breast milk, formula, cow’s milk, other milk (like soy milk), other dairy foods (like yogurt), other soy foods (like tofu), 100 percent fruit or vegetable juice, and sweet drinks, among others – their mothers fed them. Wen’s team at the University at Buffalo focused on what the infants ate over the course of a week at both 6- and 12-months old.
In many cases, infants were fed foods that would surprise even the least stringent of mothers. Candy, ice cream, soda, and french fries, for instance, were among the foods some of the babies were being fed. Researchers divided the 18 different food types into four distinct categories, two of which were ideal for infant consumption—”formula” and “infant guideline solids”—two of which were not—”high/sugar/fat/protein” and “high/regular cereal.” It became clear which babies tended to be fed appropriately, and which did not….
Science Daily reported in What do American babies eat? A lot depends on Mom’s socioeconomic background:
Dietary patterns of babies vary according to the racial, ethnic and educational backgrounds of their mothers, pediatrics researchers have found. For example, babies whose diet included more breastfeeding and solid foods that adhere to infant guidelines from international and pediatric organizations were associated with higher household income — generally above $60,000 per year — and mothers with higher educational levels ranging from some college to post-graduate education. http://www.sciencedaily.com/releases/2014/10/141030133532.htm
Cutting sugar in a child’s diet is important to improving the child’s health.
Science Daily reported in ‘Healthy’ foods differ by individual:
Ever wonder why that diet didn’t work? An Israeli study tracking the blood sugar levels of 800 people over a week suggests that even if we all ate the same meal, how it’s metabolized would differ from one person to another. The findings, published November 19 in Cell, demonstrate the power of personalized nutrition in helping people identify which foods can help or hinder their health goals.
Blood sugar has a close association with health problems such as diabetes and obesity, and it’s easy to measure using a continuous glucose monitor. A standard developed decades ago, called the glycemic index (GI), is used to rank foods based on how they affect blood sugar level and is a factor used by doctors and nutritionists to develop healthy diets. However, this system was based on studies that average how small groups of people responded to various foods.
The new study, led by Eran Segal and Eran Elinav of the Weizmann Institute of Science in Israel, found that the GI of any given food is not a set value, but depends on the individual. For all participants, they collected data through health questionnaires, body measurements, blood tests, glucose monitoring, stool samples, and a mobile-app used to report lifestyle and food intake (a total of 46,898 meals were measured). In addition, the volunteers received a few standardized/identical meals for their breakfasts.
As expected, age and body mass index (BMI) were found to be associated with blood glucose levels after meals. However, the data also revealed that different people show vastly different responses to the same food, even though their individual responses did not change from one day to another.
“Most dietary recommendations that one can think of are based on one of these grading systems; however, what people didn’t highlight, or maybe they didn’t fully appreciate, is that there are profound differences between individuals–in some cases, individuals have opposite response to one another, and this is really a big hole in the literature,” says Segal, of Weizmann’s Department of Computer Science and Applied Math…. http://www.sciencedaily.com/releases/2015/11/151119133230.htm

Here is the press release from the Weizmann Institute of Science:
Blood Sugar Levels in Response to Foods Are Highly Individual
The largest study of its kind supports the need for personalized dietary recommendations
Embargoed until 12:00 PM Eastern time, US, November 19, 2015
Which is more likely to raise blood sugar levels: sushi or ice cream? According to a Weizmann Institute study reported in the November 19 issue of the journal Cell, the answer varies from one person to another. The study, which continuously monitored blood sugar levels in 800 people for a week, revealed that the bodily response to all foods was highly individual.
The study, called the Personalized Nutrition Project (www.personalnutrition.org), was conducted by the groups of Prof. Eran Segal of the Computer Science and Applied Mathematics Department and Dr. Eran Elinav of the Immunology Department. Segal said: “We chose to focus on blood sugar because elevated levels are a major risk factor for diabetes, obesity and metabolic syndrome. The huge differences that we found in the rise of blood sugar levels among different people who consumed identical meals highlights why personalized eating choices are more likely to help people stay healthy than universal dietary advice.”
Indeed, the scientists found that different people responded very differently to both simple and to complex meals. For example, a large number of the participants’ blood sugar levels rose sharply after they consumed a standardized glucose meal, but in many others, blood glucose levels rose sharply after they ate white bread, but not after glucose. Elinav: “Our aim in this study was to find factors that underlie personalized blood glucose responses to food. We used that information to develop personal dietary recommendations that can help prevent and treat obesity and diabetes, which are among the most severe epidemics in human history.”
David Zeevi and Tal Korem, PhD students in Segal’s lab, led the study. They collaborated with Dr. Niv Zmora, a physician conducting PhD studies in Elinav’s lab, and with PhD student Daphna Rothschild and research associate Dr. Adina Weinberger from Segal’s lab. The study was unique in its scale and in the inclusion of the analysis of gut microbes, collectively known as the microbiome, which had recently been shown to play an important role in human health and disease. Study participants were outfitted with small monitors that continuously measured their blood sugar levels. They were asked to record everything they ate, as well as such lifestyle factors as sleep and physical activity. Overall, the researchers assessed the response of different people to more than 46,000 meals.
Strikingly different responses to identical foods. In study participant 445 (top), blood sugar levels rose sharply after eating bananas but not after cookies of the same amount of calories. The opposite occurred in participant 644 (bottom)
Taking these multiple factors into account, the scientists generated an algorithm for predicting individualized response to food based on the person’s lifestyle, medical background, and the composition and function of his or her microbiome. In a follow-up study of another 100 volunteers, the algorithm successfully predicted the rise in blood sugar in response to different foods, demonstrating that it could be applied to new participants. The scientists were able to show that lifestyle also mattered. The same food affected blood sugar levels differently in the same person, depending, for example, on whether its consumption had been preceded by exercise or sleep.
In the final stage of the study, the scientists designed a dietary intervention based on their algorithm; this was a test of their ability to prescribe personal dietary recommendations for lowering blood glucose level responses to food. Volunteers were assigned a personalized “good” diet for one week, and a “bad” diet – also personalized – for another. Both good and bad diets were designed to have the same number of calories, but they differed between participants. Thus, certain foods in one person’s “good” diet were part of another’s “bad” diet. The “good” diets indeed helped to keep blood sugar at steadily healthy levels, whereas the “bad” diets often induced spikes in glucose levels —all within just one week of intervention. Moreover, as a result of the “good” diets, the volunteers experienced consistent changes in the composition of their gut microbes, suggesting that the microbiome may be influenced by the personalized diets while also playing a role in participants’ blood sugar responses.
The scientists are currently enrolling Israeli volunteers for a longer-term follow-up dietary intervention study that will focus on people with consistently high blood sugar levels, who are at risk of developing diabetes, with the aim of preventing or delaying this disease.

Moi blogs about education issues so the reader could be perplexed sometimes because moi often writes about other things like nutrition, families, and personal responsibility issues. Why? The reader might ask? Children will have the most success in school if they are ready to learn. Ready to learn includes proper nutrition for a healthy body and the optimum situation for children is a healthy family. Many of society’s problems would be lessened if the goal was a healthy child in a healthy family.
