What Is a Registered Dietitian? An Interview with Khursheed Navder, PhD, RDN

Most of us would be hard-pressed to go a day without thinking or talking about food and nutrition. After all, everyone needs to eat. But what about those who want to make nutrition their career? In honor of National Nutrition Month, we’re exploring the world of registered dietitians (RDs): what it takes to become an RD, what sets them apart from other similar-sounding specialties, and how the field of nutrition is changing and adapting to new healthcare challenges. For this two-part series, we interviewed Dr. Khursheed Navder, a professor and director of the nutrition program at Hunter College in New York City, where she oversees the undergraduate, graduate and dietetic internship programs. She created the master’s of science in nutrition curriculum at Hunter and has worked to provide unique pathways for inner-city students to pursue a full-time nutrition education. She has been a recipient of the Outstanding Dietetic Educator Award from the Academy of Nutrition and Dietetics and she has held several elected positions within the Academy and the Commission on Dietetic Registration. What first made you interested in nutrition as a career path? KN: I was always fascinated by the basic sciences, by how chemistry, biology, physiology, biochemistry were all so woven into the fabric of nutrition courses. I came from India to pursue my PhD, and back then, in the mid-80s, I had absolutely no intention of working toward the RD credential since I felt I was going to be working in academia and research. Boy, am I glad my major professor at Kansas State University pushed me to pursue this credential, because this has opened many doors for me! As we all know, there is a tremendous shortage of PhD-RDs, and having had this credential has allowed me to move up the administrative ladder in academia. In […]

Parents and Caregivers are Focused on Their Kids’ Nutrition, but Obstacles to Healthy Eating are Common

(Washington, D.C.)— Our dietary habits as young children have an especially strong influence over how we eat for the rest of our lives, demonstrating the importance of promoting good nutrition early on. Yet the past year has shone a spotlight on the challenges of raising children while balancing many other priorities. Understanding the decisions made by parents and caregivers—and the hurdles they face while trying to provide food for their children—provides valuable information for improving the dietary habits of children nationwide.     A new survey by the International Food Information Council (IFIC), “Knowledge, Understanding and Behaviors When Feeding Young Children,” examines how parents and caregivers consider current diet recommendations for kids ages 2 to 10, how they interpret and implement nutrition advice, and what information sources adults rely on when making food and dietary choices for children.  While parents and caregivers report having good access to nutrition information and overall feel confident that they’re meeting their child’s nutritional needs, many cite obstacles, such as how to introduce variety into kids’ diets and how to translate aspirations into positive behaviors.   “As a parent myself, the contrast between knowing what a healthful diet looks like and actually getting a child to eat nutritiously is extremely relatable,” said Ali Webster, IFIC’s director of research and nutrition communications. “We all want to provide the best we can for our kids, and this research highlights that when it comes to nutrition, the decisions parents and caregivers make around their children’s diets aren’t always straightforward – everything from taste, price and nutrition to personal and cultural preferences need to be considered.”  Eating Habits of Young Children  When asked about the consumption of different types of foods, two in three respondents (69%) said their children eat dairy products two or more times a day, while 74% and 63% said their kids eat protein and fruit two or more times per day, respectively. Just one in five (19%) said their child eats grains at least three times a day. While 91% said that their children eat vegetables at least once per day, only one in five (19%) said they eat them 3 or more times daily.  Indeed, vegetables emerged as […]

Fast Take: Do Ultraprocessed Foods Cause Weight Gain?

While the quantity and quality of processed foods in our diets continue to be a major focus in articles and discussions about diet, the role of ultraprocessed foods is now gaining more attention. A new study published in Cell Metabolism is bringing the topic of ultraprocessed back in the news­­. This time, researchers are examining the link among ultraprocessed foods, calorie intake and weight gain. You may have seen the headlines, but what about the findings? Let’s take a closer look. How Was the Study Done? This study was a randomized control trial (RCT) conducted on twenty healthy people (ten males and ten females). Study participants were between the ages of 18 and 50 (the average age was 31), had a body mass index (BMI) above 18.5 (the average BMI was 27) and had body weights that had remained stable during the six months prior to the study. For 28 days, the participants lived at the National Institutes of Health facility in Bethesda, Maryland, where all their daily food and drinks were provided for them. The study assessed participants’ food intake and the resulting changes in their body weights. Two diets were tested in the study: one consisting entirely of ultraprocessed foods and the other containing only unprocessed foods. The diets were equal in total calories, macronutrients (fat, carbohydrates and protein), sugars, sodium and fiber. To construct the meal plans, study authors used the NOVA classification system, which characterizes food processing in the following four groups: (1) unprocessed or minimally processed foods, (2) processed culinary ingredients, (3) processed foods, and (4) ultraprocessed foods. In other words, the “unprocessed” diet was put together with foods from group 1 and the “ultraprocessed” diet was made with foods from group 4. Randomly, ten people were assigned to begin with the ultraprocessed diet for […]

Metals in Food and Water: What You Need To Know To Protect Your Health

Although it may sound alarming, metals in our food supply is nothing new. Metals are natural elements found in Earth’s crust, and they often make their way into plant-based foods through irrigation and soil and dust particles, frequently with some “help” from humans (e.g. through sediments from smoking, the use of lead pipes in construction, some forms of paint, and other materials). In the field of food and nutrition, trace elements, or “trace metals,” can actually be beneficial to human health across the life stages. However, with news about “toxic metals” in our food on the rise, we may be feeling concerned about our health and well-being—and the well-being of those we provide food for every day. The good news is that emerging technologies are allowing scientists to test for metals with better and better sensitivity. These findings have advanced federal policies, nutritional guidance, and national health goals. For example, the U.S. Department of Health and Human Services’ Healthy People 2030 General Environment Health lays out objectives for reducing specific metals, as does the U.S. Food and Drug Administration (FDA)’s Closer to Zero: Action Plan for Baby Foods document that was shared in 2020. Since 1961, the FDA has tested and monitors metals and other elements in our food through the Total Diet Study. These efforts are overseen by the FDA’s Toxic Elements Working Group, which aims to reduce consumer exposure to toxic elements in food, dietary supplements, and cosmetics. “Toxic” elements in this context include, but are not limited to, cadmium (Cd), lead (Pb), mercury (Hg), and arsenic (As), all of which you can find more information about below. Lastly, current best-practice manufacturing guidelines during food processing, as well as the documentation of land-use history and water-quality at the farming level of our food supply chain, also help maintain […]

When Is the Best Time To Introduce Potential Allergenic Foods to Your Infant?

The possibility of an allergic reaction after eating gives many Americans pause when making food choices. No one wants to worry that a bite into a savory sandwich or decadent dessert will cost them a swollen lip—or worse, a trip to the E.R. As adults, we have more control when it comes to the foods we are exposed to, but what about children? Or better yet, infants? When should we introduce potentially allergenic foods to our babies? According to Food Allergy Research & Education (FARE), food allergies among kids have increased over the last couple of decades. Faced with uncertainty, many parents avoid feeding their babies certain foods in the hope of preventing a potential allergic reaction. But is such avoidance helpful in the long run? Food allergies are a public health concern The U.S. Food and Drug Administration recognizes nine major food allergens: milk, eggs, fish, shellfish, tree nuts, wheat, peanuts, sesame and soybeans. Allergic reactions can vary from person to person and may also result from foods not included in the “Big Nine.” If you are allergic to an allergenic food, eating that food activates your immune system, causing your body to think the food is an “invader.” When your immune system is unnecessarily activated, many parts of the body—including your gut and other organs and tissues—can be affected. Sometimes, one allergic reaction can make you more sensitive to other allergens. Food allergies are serious, and they can be life-threatening, especially for infants, who cannot tell you when something feels wrong. Currently, one in 13 children in the U.S. has food allergies. Food allergy rates have steadily increased over the past couple decades, presenting a major concern for parents, health care workers and public health professionals alike. To help families identify potential allergens, legislation (like FALCPA) has been passed, […]

What You Should Know About Plant-Based Alternatives to Meat

Download the Fact Sheet Here Vegetarian alternatives to meat are nothing new—veggie burgers, vegan deli meat and chicken-less nuggets have been around for decades. But while these products typically have aimed to meet the needs of vegetarians and vegans and don’t consistently match the taste and texture of meat, newer plant-based alternatives to meat are attempting to mimic animal proteins as much as possible. In this explainer, we’ll take a closer look at how these products are made, their nutritional attributes, and their environmental impact. To date, many of these new products have been created to serve as alternatives to foods traditionally made with red meat, like burgers and sausages, so we’ll focus on these alternatives. However, new products meant to mimic poultry, eggs and seafood are now also being sold, and more are coming to store shelves—an indicator that this novel wave in protein innovation may just be getting started. How are plant-based alternatives to meat made? Plant-based alternatives to animal meat are made with ingredients and processing techniques that create colors, textures and flavors that are similar to those of animal meat. Protein sources in these plant products range from soy and potatoes to peas, rice and mung beans. The type of dietary fats used to make them include canola oil, cocoa butter, coconut oil and sunflower oil, and they’re usually bound together by methylcellulose, which is used as a thickener and emulsifier in many types of foods. In addition to the ingredients needed to build color, structure and flavor, plant-based alternatives to meat are sometimes fortified with vitamins and minerals, like vitamin B12 and zinc, in order to offer some of the same nutrients that are inherent to animal meat. How do plant-based alternatives stack up nutritionally? Even though meatless protein foods benefit from a “health halo” […]

Four Heart-Healthy Snack Ideas

According to our 2024 Food and Health Survey, 73% of consumers report snacking at least once a day, which is consistent with 2022 data but represents an increase from the 58% who said the same in 2021. The 2024 survey found that 30% are seeking out heart and cardiovascular health benefits from their food choices. Let’s bridge the gap and share a few heart-healthy snacks. Nuts Nuts are full of healthy fats, including mono- and polyunsaturated fats. Research suggests that eating 1.5 ounces of most nuts per day as part of a low-saturated-fat diet may reduce the risk of heart disease. And with nuts, there are also a ton of options to meet your taste preferences: Peanuts, almonds, hazelnuts, cashews, and walnuts are just a few common varieties of nuts. Nuts also pack in protein, fiber, vitamins, and minerals; have a long shelf life; and are portable, making them a great on-the-go snack option. Dairy Including fat-free and low-fat dairy products in your diet is recommended for an overall healthy dietary pattern that also supports heart health. Just keep in mind that this doesn’t mean you should avoid fat altogether, especially healthy unsaturated fats like those found in vegetable oils, nuts, seeds and fatty fish. Besides milk, dairy products include yogurt, cheese, and fortified soymilk, which are sources of protein and micronutrients like calcium, potassium and vitamin D. Some go-to dairy snacks include yogurt cups, string cheese, or snack-sized milk or soymilk. Whole Grains Whole grains have been shown to promote heart health in a variety of ways, including by lowering cholesterol, blood lipid levels, and blood pressure. Studies show that individuals with three or more servings of whole-grain foods per day have a 20 to 30 percent lower risk for cardiovascular disease compared with those who have lower intakes […]

Vitamins and Minerals Fact Sheets

From Vitamin A to Zinc, there are so many vitamins and minerals in foods that are important to our health. It can be hard to keep track of what vitamin is beneficial for which body function and most importantly, where to find these important nutrients in food. These fact sheets provide all the info you need to know about vitamins and minerals in food. Of course, this is not an exhaustive list but it’s a good start towards making sure you are eating the right foods to get the nutrients you need. Minerals Fact Sheet Minerals may seem really complex and confusing. With so many different minerals, it can be hard to keep track of what they are, what they do, and where you can find them. By using this fact sheet, you can make all this information seem “elemental” and become a rock-solid expert regarding minerals. Did You Know? There are two types of essential minerals: major minerals (macrominerals) and trace minerals (microminerals). Both are needed and equally important, but trace minerals are needed in less amounts than major minerals. According to the 2015-2020 Dietary Guidelines for Americans, vitamin D, calcium, potassium, iron, and dietary fiber are considered nutrients of public health concern because low intakes are associated with negative health conditions. About 99% of the human body is made up of 6 elements: two of which include calcium and phosphorus! Mineral Functions in the Body Where to Find in Foods and Beverages Calcium Dental health, nerve health, muscle health, bone health Animal-based foods like milk, yogurt, and cheese; plant-based foods like kale and broccoli; and fortified foods like breakfast cereals, soy foods and fruit juices Chloride Heart health, nerve health, muscle health Salt, seaweed, rye, tomatoes, lettuce, celery, and olives Chromium Metabolism Animal-based foods like meat, poultry, fish, […]
