Abstract

Chickpea and other pulses are commonly sold as canned products packed in a thick solution or a brine. This solution has recently been shown to produce stable foams and emulsions, and can act as a thickener.

Recently interest in this product has been enhanced through the internet where it is proposed that this solution, now called aquafaba by a growing community, can be used a replacement for egg and milk protein.

As aquafaba is both new and being developed by an internet based community little is known of its composition or properties. Aquafaba was recovered from 10 commercial canned chickpea products and correlations among aquafaba composition, density, viscosity and foaming properties were investigated.

Proton NMR was used to characterize aquafaba composition before and after ultrafiltration through membranes with different molecular weight cut offs (MWCOs of 3, 10, or 50 kDa). A protocol for electrophoresis, and peptide mass fingerprinting is also presented. Those methods provided valuable information regarding components responsible for aquafaba functional properties.

This information will allow the development of practices to produce standard commercial aquafaba products and may help consumers select products of superior or consistent utility.

Summary

Aquafaba, the viscous liquid resulting from cooking chickpeas in water is typically discarded. However, this solution is now widely used by the vegan community as an egg replacement that adds texture to food products, such as mayonnaise, pudding, ice cream and baked goods.

Sponge cake was prepared with either egg white or aquafaba derived from ten different brands of canned chickpea and the texture and colour were compared. Aquafaba obtained from each chickpea can produced foam which differed in both properties and stability.

In addition, aquafaba from some brands provided comparable foam volume and stability to that achieved with egg white.

The colour and texture of sponge cake made with either egg white or aquafaba were similar and acceptable, but cakes prepared with aquafaba were less springy, and less cohesive than cake that included egg white.

Based on our results, it appears that aquafaba has potential to replace egg white in eggless cake recipes.

Internship Opportunities with the WFP – Ethiopia

In Over-nutrition, Under-nutrition on September 5, 2018 at 7:00 pm

Background

Ethiopia has made important development gains over the past two decades, reducing poverty and expanding investments in basic social services. However, food insecurity and under-nutrition still hinder economic growth. In 2015 it ranked 174 out of 188 in the UNDP Human Development Report. The country is also home to the second largest refugee population on the continent; it currently hosts 909,000 registered refugees from South Sudan, Somalia, Sudan, Eritrea and Kenya. 2016 was a challenging year for Ethiopia as it suffered from the worst El Niño impact in the last 50 years. The onset of El Niño combined with failed Belg (spring harvest) and Meher (main harvest) rains in 2015 left 10.2 million people in need of emergency food and nutrition assistance. While the Government and partners averted a major humanitarian catastrophe, the drought has left a negative legacy on many families, who lost livestock and other productive assets. The residual needs from the past year have been compounded by a new and devastating drought which hit Ethiopia and other parts of the Horn of Africa in early 2017. In  August 2017, the Government of Ethiopia released the Mid-Year Humanitarian Requirements Document which outlined the need to support 8.5 million people with emergency food, nutrition, health, water and education programmes. WFP supports the Ethiopian Government through a range of life-saving and resilience-building activities as well as providing assistance in refugee camps. We use food, cash, nutrition assistance and innovative approaches to improve nutrition, empower women, build local capacities and enhance preparedness to climate-related shocks.

 

Opportunity – WFP Ethiopia Country Office seeks (1) graduate (BSc), and post-graduate (MSc) students looking for field-based dissertation topics, (2) BSc and MSc students already graduated within a year, looking for opportunity hands-on work experience, and (3) researchers looking for settings where to develop operational research topics. Background: Nutrition/Public Health/Epidemiology, Food Technology, Communication, Social Sciences, Logistics, Engineering, Economy and any other field related to food and nutrition.

Abstract

OBJECTIVES:

Cardiometabolic diseases are increasing disproportionately in South Asia compared with other regions of the world despite high levels of vegetarianism. This unexpected discordance may be explained by differences in the healthfulness of vegetarianand non-vegetarian diets in South Asia compared with the United States. The aim of this study was to compare the food group intake of vegetarians with non-vegetarians in South Asia and the United States and to evaluate associations between vegetarianism and cardiometabolic disease risk factors (overweight/obesity, central obesity, diabetes, hypertension, high triacylglycerols, high low-density lipoprotein, low high-density lipoprotein, and high Framingham Heart Score).

METHODS:

Using cross-sectional data from adults (age 20-69 y) in South Asia (Centre for Cardiometabolic Risk Reduction in South-Asia [CARRS] 2010-2011; N = 15 665) and the United States (National Health and Nutrition Examination Survey 2003-2006; N = 2159), adherence to a vegetarian diet was assessed using food propensity questionnaires. Multivariable logistic regression was used to estimate odds ratios and predicted margins (e.g., adjusted prevalence of the outcomes).

RESULTS:

One-third (33%; n = 4968) of adults in the South Asian sample were vegetarian compared with only 2.4% (n = 59) in the US sample. Among South Asians, vegetarians more frequently ate dairy, legumes, vegetables, fruit, desserts, and fried foods than non-vegitarians (all P < 0.05). Among Americans, vegetarians more frequently ate legumes, fruit, and whole grains, and less frequently ate refined cereals, desserts, fried foods, fruit juice, and soft drinks than non-vegetarians (all P < 0.05). After adjustment for confounders (age, sex, education, tobacco, alcohol, and also city in CARRS), South Asian vegetarians were slightly less frequently overweight/obese compared with non-vegetarians: 49% (95% confidence interval [CI], 45%-53%) versus 53% (95% CI, 51%-56%), respectively; whereas US vegetarians were considerably less frequently overweight/obese compared with non-vegetarians: 48% (95% CI, 32%-63%) versus 68% (95% CI, 65%-70%), respectively. Furthermore, US vegetarians were less likely to exhibit central obesity than non-vegetarians: 62% (95% CI, 43%-78%) versus 78% (95% CI, 76%-80%), respectively.

CONCLUSIONS:

There is greater divergence between vegetarian and non-vegetarian diets in the United States than in South Asia, and US vegetarians have more consistently healthier food group intakes than South Asian vegetarians. Vegetarians in both populations have a lower probability of overweight/obesity compared with non-vegetarians. The strength of this association may be stronger for US vegetarian diets, which were also protective against central obesity.

Abstract

It is the position of the American Dietetic Association that appropriately planned vegetarian diets, including total vegetarian or vegan diets, are healthful, nutritionally adequate, and may provide health benefits in the prevention and treatment of certain diseases. Well-planned vegetarian diets are appropriate for individuals during all stages of the life cycle, including pregnancy, lactation, infancy, childhood, and adolescence, and for athletes. A vegetarian diet is defined as one that does not include meat (including fowl) or seafood, or products containing those foods.

This article reviews the current data related to key nutrients for vegetarians including protein, n-3 fatty acids, iron, zinc, iodine, calcium, and vitamins D and B-12. A vegetarian diet can meet current recommendations for all of these nutrients. In some cases, supplements or fortified foods can provide useful amounts of important nutrients. An evidence- based review showed that vegetarian diets can be nutritionally adequate in pregnancy and result in positive maternal and infant health outcomes.

The results of an evidence-based review showed that a vegetarian diet is associated with a lower risk of death from ischemic heart disease. Vegetarians also appear to have lower low-density lipoprotein cholesterol levels, lower blood pressure, and lower rates of hypertension and type 2 diabetes than nonvegetarians.

Furthermore, vegetarians tend to have a lower body mass index and lower overall cancer rates. Features of a vegetarian diet that may reduce risk of chronic disease include lower intakes of saturated fat and cholesterol and higher intakes of fruits, vegetables, whole grains, nuts, soy products, fiber, and phytochemicals.

The variability of dietary practices among vegetarians makes individual assessment of dietary adequacy essential. In addition to assessing dietary adequacy, food and nutrition professionals can also play key roles in educating vegetarians about sources of specific nutrients, food purchase and preparation, and dietary modifications to meet their needs.

Free Book on global – Pages: 150
IFPRI’s flagship report reviews the major food policy issues, developments, and decisions of 2017, and highlights challenges and opportunities for 2018 at the global and regional levels. This year’s report looks at the impacts of greater global integration—including the movement of goods, investment, people, and knowledge—and the threat of current antiglobalization pressures. Drawing on recent research, IFPRI researchers and other distinguished food policy experts consider a range of timely topics:

 

■ How can the global food system deliver food security for all in the face of the radical changes taking place today?

■ What is the role of trade in improving food security, nutrition, and sustainability?

■ How can international investment best contribute to local food security and better food systems in developing countries?

■ Do voluntary and involuntary migration increase or decrease food security in source countries and host countries?

■ What opportunities does greater data availability open up for improving agriculture and food security?

■ How does reform of developed-country farm support policies affect global food security?

■ How can global governance structures better address problems of food security and nutrition?

■ What major trends and events affected food security and nutrition across the globe in 2017?

The 2018 Global Food Policy Report also presents data tables and visualizations for several key food policy indicators, including country-level data on hunger, agricultural spending and research investment, and projections for future agricultural production and consumption.  In addition to illustrative figures, tables, and a timeline of food policy events in 2017, the report includes the results of a global opinion poll on globalization and the current state of food policy.

Opposition to Breast-Feeding Resolution by U.S. Stuns World Health Officials

In Over-nutrition, Under-nutrition on July 11, 2018 at 7:58 am

source: NY times web page

A resolution to encourage breast-feeding was expected to be approved quickly and easily by the hundreds of government delegates who gathered this spring in Geneva for the United Nations-affiliated World Health Assembly.Based on decades of research, the resolution says that mother’s milk is healthiest for children and countries should strive to limit the inaccurate or misleading marketing of breast milk substitutes.Then the United States delegation, embracing the interests of infant formula manufacturers, upended the deliberations.
American officials sought to water down the resolution by removing language that called on governments to “protect, promote and support breast-feeding” and another passage that called on policymakers to restrict the promotion of food products that many experts say can have deleterious effects on young children.

When that failed, they turned to threats, according to diplomats and government officials who took part in the discussions. Ecuador, which had planned to introduce the measure, was the first to find itself in the cross hairs.The Americans were blunt: If Ecuador refused to drop the resolution, Washington would unleash punishing trade measures and withdraw crucial military aid. The Ecuadorean government quickly acquiesced.

The showdown over the issue was recounted by more than a dozen participants from several countries, many of whom requested anonymity because they feared retaliation from the United States.

Health advocates scrambled to find another sponsor for the resolution, but at least a dozen countries, most of them poor nations in Africa and Latin America, backed off, citing fears of retaliation, according to officials from Uruguay, Mexico and the United States.

“We were astonished, appalled and also saddened,” said Patti Rundall, the policy director of the British advocacy group Baby Milk Action, who has attended meetings of the assembly, the decision-making body of the World Health Organization, since the late 1980s.

“What happened was tantamount to blackmail, with the U.S. holding the world hostage and trying to overturn nearly 40 years of consensus on the best way to protect infant and young child health,” she said.In the end, the Americans’ efforts were mostly unsuccessful. It was the Russians who ultimately stepped in to introduce the measure — and the Americans did not threaten them.

During the deliberations, some American delegates even suggested the United States might cut its contribution to the W.H.O., several negotiators said. Washington is the single largest contributor to the health organization, providing $845 million, or roughly 15 percent of its budget, last year.

The confrontation was the latest example of the Trump administration siding with corporate interests on numerous public health and environmental issues.

In talks to renegotiate the North American Free Trade Agreement, the Americans have been pushing for language that would limit the ability of Canada, Mexico and the United States to put warning labels on junk food and sugary beverages, according to a draft of the proposal reviewed by The New York Times.

During the same Geneva meeting where the breast-feeding resolution was debated, the United States succeeded in removing statements supporting soda taxes from a document that advises countries grappling with soaring rates of obesity.

The Americans also sought, unsuccessfully, to thwart a W.H.O. effort aimed at helping poor countries obtain access to lifesaving medicines. Washington, supporting the pharmaceutical industry, has long resisted calls to modify patent laws as a way of increasing drug availability in the developing world, but health advocates say the Trump administration has ratcheted up its opposition to such efforts.

The delegation’s actions in Geneva are in keeping with the tactics of an administration that has been upending alliances and long-established practices across a range of multilateral organizations, from the Paris climate accord to the Iran nuclear deal to Nafta.

Ilona Kickbusch, director of the Global Health Centre at the Graduate Institute of International and Development Studies in Geneva, said there was a growing fear that the Trump administration could cause lasting damage to international health institutions like the W.H.O. that have been vital in containing epidemics like Ebola and the rising death toll from diabetes and cardiovascular disease in the developing world.

“It’s making everyone very nervous, because if you can’t agree on health multilateralism, what kind of multilateralism can you agree on?” Ms. Kickbusch asked.

A Russian delegate said the decision to introduce the breast-feeding resolution was a matter of principle.“We’re not trying to be a hero here, but we feel that it is wrong when a big country tries to push around some very small countries, especially on an issue that is really important for the rest of the world,” said the delegate, who asked not to be identified because he was not authorized to speak to the media.He said the United States did not directly pressure Moscow to back away from the measure. Nevertheless, the American delegation sought to wear down the other participants through procedural maneuvers in a series of meetings that stretched on for two days, an unexpectedly long period.In the end, the United States was largely unsuccessful. The final resolution preserved most of the original wording, though American negotiators did get language removed that called on the W.H.O. to provide technical support to member states seeking to halt “inappropriate promotion of foods for infants and young children.”

The United States also insisted that the words “evidence-based” accompany references to long-established initiatives that promote breast-feeding, which critics described as a ploy that could be used to undermine programs that provide parents with feeding advice and support.

Elisabeth Sterken, director of the Infant Feeding Action Coalition in Canada, said four decades of research have established the importance of breast milk, which provides essential nutrients as well as hormones and antibodies that protect newborns against infectious disease.

A 2016 study in The Lancet found that universal breast-feeding would prevent 800,000 child deaths a year across the globe and yield $300 billion in  savings from reduced health care costs and improved economic outcomes for those reared on breast milk.

Scientists are loath to carry out double-blind studies that would provide one group with breast milk and another with breast milk substitutes. “This kind of ‘evidence-based’ research would be ethically and morally unacceptable,” Ms. Sterken said.

Abbott Laboratories, the Chicago-based company that is one of the biggest players in the $70 billion baby food market, declined to comment.

Nestlé, the Switzerland-based food giant with significant operations in the United States, sought to distance itself from the threats against Ecuador and said the company would continue to support the international code on the marketing of breast milk substitutes, which calls on governments to regulate the inappropriate promotion of such products and to encourage breast-feeding.

In addition to the trade threats, Todd C. Chapman, the United States ambassador to Ecuador, suggested in meetings with officials in Quito, the Ecuadorean capital, that the Trump administration might also retaliate by withdrawing the military assistance it has been providing in northern Ecuador, a region wracked by violence spilling across the border from Colombia, according to an Ecuadorean government official who took part in the meeting.

The United States Embassy in Quito declined to make Mr. Chapman available for an interview.

“We were shocked because we didn’t understand how such a small matter like breast-feeding could provoke such a dramatic response,” said the Ecuadorean official, who asked not to be identified because she was afraid of losing her job.
