Everything You Need To Know About Glutamate And Monosodium Glutamate

Eating is one of life’s pleasures. Taste and flavor are important to enjoying food. Think about a bowl of hot pasta with tomato sauce and parmesan cheese, a freshly grilled steak with a rich mushroom sauce, or stir-fried seafood and chicken with crisp vegetables in a savory sauce. These subtle, delicate flavors result from centuries of culinary tradition, including careful attention to ingredients and preparation. In all of these dishes, glutamate is one of the major food components that provides flavor. What is Glutamate? Glutamate is an amino acid, found in all protein-containing foods. Amino acids are the building blocks of proteins. This amino acid is one of the most abundant and important components of proteins. Glutamate occurs naturally in protein-containing foods such as cheese, milk, mushrooms, meat, fish, and many vegetables. Glutamate is also produced by the human body and is vital for metabolism and brain function. What is Monosodium Glutamate? Monosodium glutamate, or MSG, is the sodium salt of glutamate. When MSG is added to foods, it provides a similar flavoring function as the glutamate that occurs naturally in food. MSG is comprised of nothing more than water, sodium and glutamate. Why is MSG used? MSG is a flavor enhancer that has been used effectively to bring out the best taste in foods, emphasizing natural flavors. Many researchers also believe that MSG imparts a fifth taste, independent of the four basic tastes of sweet, sour, salty and bitter. This taste, called “umami” in Japan, is described by Americans as savory. Examples of each of these tastes are: Sweet – Sugar, Bitter – Coffee, Savory – Tomato, Sour – Lemon, Salt – Anchovy How is MSG made? In the early 1900s, MSG was extracted from natural protein-rich foods such as seaweed. Today, MSG is made from starch, corn sugar […]

The Science of Taste

Confucius said, “Everyone eats and drinks, but few appreciate taste.” When you understand a bit about the science of taste, you may join the few who appreciate it. In fact, the science of taste is amazing. The human sensory systems allow us to distinguish about 100,000 different flavors.  Flavors emanate from our bodies’ ability to discern one taste from another.  And, according to the 2017 Food & Health Survey, taste reigns with 84 percent of Americans confirming it as “a top driver of [food] purchases.”  What’s the difference between taste and flavor? If you hold your nose, close your eyes and eat chocolate, you may not know what you are eating. Without your sense of smell, chocolate just tastes sweet or bitter. If you have ever tried to enjoy a meal with a head cold, you know how much your sense of smell adds to flavor. Flavor is more than just odor and taste. It also includes texture and temperature. It even includes the sense of pain, which is what you get from capsaicin in chili peppers. Put it all together and you have the ability to discern 100,000 different flavors. How did our sense of taste evolve? Over millions of years, our sense of taste evolved to help us choose which foods to eat. Choosing the wrong food could mean wasted energy, poor nutrition or poisoning from eating something that can do harm to our bodies. According to Current Biology Perspective on Food and Human Taste, humans relied on fruit and other plant-based foods and eventually developed a strong sense for the natural bitter taste in plants and leaves. As time progressed, we retained these early taste preferences and acquired newer ones. We like the taste of sweet because it signifies a source of sugar, which means energy. We […]

A Brief History of Food Fortification in the U.S.

According to the World Health Organization (WHO), food fortification is the practice of deliberately increasing the content of one or more micronutrients (i.e., vitamins and minerals) in a food or condiment to improve the nutritional quality of that food—thereby providing a public health benefit with minimal risk to individual health. But why would fortification be necessary? Over decades of research, fortification has been identified as one of the most cost-effective nutrition interventions available, particularly for low- and middle-income countries around the globe. In fact, the worldwide fortification of commonly consumed foods provides enhanced nutrient intake throughout the lifespan for populations that are at risk for widespread nutritional deficiencies. Even in wealthier countries, like the United States, fortification has led to positive health benefits for the entire population. In the U.S., micronutrient deficiency diseases like goiter, rickets, beriberi, and pellagra were once common health problems as recently as the 20th century. Thanks to systematic fortification within the U.S. food supply, these diseases have been virtually eliminated. Read on to learn more about the historical origins of food fortification in the U.S., as well as insights into fortification’s contributions to improved public health. But before we dive in, let’s define two food-related terms that are often used interchangeably but are slightly different: The 1920s: Iodine in Salt During the 1921 American Medical Association (AMA) convention, two Ohio doctors presented findings from their clinical trial demonstrating the effectiveness of sodium iodide treatments for the prevention of goiter in Akron schoolgirls. Prior to their study, research from Europe had also suggested an association between iodine deficiency and goiter (an enlarged thyroid gland). It was found that without iodine, the body could not properly make thyroid hormones, which often resulted in an unsightly neck goiter or, in more serious cases, neurocognitive impairments. Iodine deficiency generally occurs […]

IFIC Spotlight Survey: Plant Alternatives To Animal Meat

Every so often a new food trend captures our attention, only to fade once the novelty wears off. Other times, food trends have more staying power. The original veggie burger dates back decades, but more recently a new generation of plant alternatives to animal meat has exploded on the food scene, distinguished from their predecessors by the intent to mimic animal meat’s taste and texture. The International Food Information Council (IFIC) commissioned an online research survey with consumers based in the US to measure knowledge, attitudes, and beliefs about plant alternatives to animal meat. One thousand adults aged 18+ years completed the survey from December 20-23, 2019, and responses were weighted to ensure proportional results.  Key findings include:

Fortification FTW (For the Win)

The goiter belt is a term for parts of the U.S. (including the Great Lakes region and Appalachia) where soil levels of iodine are naturally low and iodine-rich foods like seafood and seaweed are not exactly dietary staples. Before the 1920s, over half of the population in some parts of this region had goiter, an abnormal enlargement of the thyroid gland caused by insufficient iodine intake. Why don’t we have goiter? In 1924, the U.S. started fortifying salt with iodine, which virtually eradicated the goiter problem. Because of fortification, we don’t have goiter. Or beriberi, pellagra, and rickets. Fortification, or adding nutrients (like iodine) to foods (like salt), has been one of the most successful public health interventions in U.S. history and has virtually eliminated diseases, like goiter, that are caused by nutrient deficiencies. Beriberi, pellagra, and rickets are also diseases of nutrient deficiencies that have mostly disappeared, thanks to fortification of other foods with thiamin, niacin, and Vitamin D. Food that have nutrients added to them are also sometimes called enriched foods. While the terms “fortified” and “enriched” can be used interchangeably sometimes, enrichment typically refers to adding nutrients lost during food handling, processing, or storage back to a food. Fortification, on the other hand, generally refers to foods that have had nutrients added to them that are not naturally occurring in that food (like iodine added to salt). Unlike fortified foods, many enriched foods must have specific amounts of certain vitamins added to them to meet official FDA definitions. One well-known enriched food is refined wheat flour, i.e. white flour. Enriched flour must contain specific amounts of B vitamins (thiamin, riboflavin, niacin, and folic acid) and iron. Calcium is sometimes added to enriched flour as well. Just as iodine is added to salt to prevent goiter, these B vitamins […]

Solving Sodium: New Consumer Research Signals Significant Knowledge Gaps, Consumption Concerns & Motivation to Improve Health

(Washington, D.C.) — Salt (i.e., sodium chloride) has consistently been indispensable for preserving, improving texture and enhancing flavor of our food, in addition to sodium’s role as an essential nutrient in human nutrition. But despite these benefits, excess dietary sodium intake is linked to health issues, such as high blood pressure, heart disease and stroke. The International Food Information Council’s (IFIC) latest Spotlight Survey: American Consumer Perceptions of Sodium In The Diet dives into the U.S. consumer mindset, their knowledge of how much they consume contrasted with the recommended amounts, and trusted sources of information about sodium. “Effective communication begins with understanding consumers’ knowledge of sodium recommendations and their perceptions of just how much sodium they believe they consume every day. After conducting our research, we unveiled major knowledge gaps when it comes to individual sodium intake and dietary guidance recommendations,” IFIC President & CEO, Wendy Reinhardt Kapsak, MS, RDN, said. “These insights are critical in educating the public and ultimately, improving public health.” Nine Out Of 10 Americans Consume Too Much Sodium Dietary guidance suggests that American adults should consume no more than 2,300 milligrams (mg) of sodium per day, however the average American adult consumes about 3,400 mg. In fact, according to National Health and Nutrition Examination Survey (NHANES) data, nine out of 10 Americans consume too much sodium. More than 70% of the sodium that Americans consume comes from packaged and prepared foods, while about 11% is added during cooking or eating. According to the latest IFIC consumer research, when Americans consider sources of sodium in their diets, 29% say the top source is packaged foods, such as canned food or frozen meals. Nearly four in ten say their top sources of dietary sodium are the salt added during cooking (22%) or while eating (15%). “Our research […]

Nutrition 101 Video Series: Monosodium glutamate (MSG)

This is the seventh installment of our “Nutrition 101” video series, presented in partnership with Osmosis, a group that focuses on health science education, highlighting the basics of several nutrition topics. For a look back at what we’ve covered so far, watch our videos on  fats,  carbohydrates and sugars,  hydration, low-calorie sweeteners, protein and gut health.  Savory foods are inherently delicious—but have you ever wondered why? In 1908, a Japanese professor pondered this question when exploring what made kelp broth taste so good. He recognized a unique taste in it that was different from the four well-known tastes of sweet, sour, bitter and salty. It turns out that glutamate, an amino acid made by many plants and animals, was the source of this distinctive taste, which became known as “umami” in reference to “umai,” the Japanese word for delicious. The professor isolated glutamate from seaweed to produce a crystallized salt form of glutamate that combined one molecule of glutamate with the ion sodium to make it even tastier. This umami seasoning is still widely used today and is also known as monosodium glutamate, or MSG. Glutamate is the most abundant amino acid found in nature, and it’s one of the 20 amino acids that make up proteins in the human body. Because glutamate is synthesized as part of the normal metabolic process, it is considered a non-essential amino acid. In other words, we don’t technically need to get it from food. Our bodies synthesize about 50 grams of glutamate each day and store about 4.5 pounds of glutamate in major organs like the brain, muscles, kidneys and liver. On average we eat about 10 to 20 grams of glutamate each day, mostly from protein-containing foods like meat, cheese, nuts and legumes. Whether consumed from food or in the form of MSG, […]

IFIC Spotlight Survey: Consumer Attitudes About Labeling Cow’s Milk, Plant Based & Non-Dairy Alternatives

As the U.S. Food and Drug Administration considers a proposal “to provide greater clarity on appropriate labeling of plant-based alternatives” to milk and dairy products, a new survey by the International Food Information Council (IFIC) Foundation shows a low level of consumer confusion over nomenclature and basic differences between the two. The International Food Information Council (IFIC) commissioned an online research survey with consumers based in the US to measure knowledge, attitudes, and beliefs about cow’s milk, plant-based and non-dairy alternatives. One thousand adults aged 18+ years completed the survey from August 4-6, 2018, and responses were weighted to ensure proportional results. The research was supported by Danone North America PBC.
