Odds are you鈥檝e scanned food labels while shopping for groceries 鈥 but do you know how they can help you make healthier choices at mealtime?
鈥淭he nutrition facts label is a valuable tool that offers details about the nutrients in each food item such as calories, protein, added sugar and vitamins,鈥 says Alexis Lopez, MS, RD, a clinical nutrition specialist with 喵咪社区. 鈥淭his information can help you choose healthier food options.鈥
To help you navigate nutrition labels like a pro, Lopez shares 5 tips on how to read food labels and how to apply it to your daily life.
鈥淭he serving size is displayed at the top of the label in bold text,鈥 Lopez says. 鈥淭his serving size now reflects the typical amount people consume of the product. It is important to know that this is not a portion size recommendation.鈥
If you consume an entire container of a food or drink item that lists 5 servings per container, you will need to multiply the values in each category on the food label by 5 to determine the total calories and nutrients you consumed, she adds.
鈥淓ating more calories than your body needs may result in weight gain, as individual calorie needs vary from person to person,鈥 Lopez says. If you want further guidance on your specific needs, she recommends consulting a dietitian.
According to the (CDC), obesity affects 41.9% of U.S. adults and 19.7% of children and teenagers. And obesity-related conditions, such as heart disease, Type 2 diabetes and certain cancers, are on the rise.
鈥淭he calories listed per serving on the food label apply only to that specific serving size, which is placed above the calories,鈥 Lopez explains. 鈥淚f you consume more than the stated serving size, you will need to multiply the calorie amount to reflect the amount you ate.鈥
For example, if your food has 20 calories per serving and you eat 5 servings, you have to multiply 20 by 5 for a total of 100 calories. Currently, the nutrition facts label is based on an average diet of 2,000 calories per day.
鈥淭he daily calorie needs for an individual depend on their energy needs and activity level, which may be higher or lower than the 2,000 calories that is referenced on the food label,鈥 Lopez says. Your primary care provider or a registered dietitian can help you determine the number of daily calories that are best for you.
Year the FDA updated the nutrition label to show new nutrition science
Calories per day for an average diet (basis for food labels)
Maximum grams of added sugar per day recommended for women
Maximum grams of added sugar per day recommended for men
鈥淭he percent of daily value (%DV) provides the nutrient content of the product, helping you assess your daily intake and determine if you meet your individual needs,鈥 Lopez says.
The percent of daily value (%DV) showcases three important facts about your food:
鈥淚f you are managing diabetes, you might focus on the total carbohydrate section and look for products with a low percentage of added sugar and a higher percentage of dietary fiber,鈥 Lopez says.
Another helpful tip to keep in mind about the percent of daily value:
鈥淭hese percentages represent the most recent scientific research on the daily nutrient intake we should incorporate into our diets,鈥 Lopez says. 鈥淚t is important to choose foods that are low in saturated fat, trans fat and added sugar while focusing on those that are rich in vitamin D, calcium, iron, potassium and dietary fiber.鈥
There are two types of sugars in the food you eat. The first occur naturally and are found in foods such as fruits and milk. The second, known as , do not occur naturally and are added to a product during processing.
Added sugars do not provide nutritional benefit. They are listed on the nutrition label as a percent daily value (%DV) because you should limit your intake of added sugars to less than 10% of your total calorie daily, Lopez explains.
The (AHA) recommends no more than 25 grams, or 6 teaspoons, of added sugars per day for women, and no more than 36 grams, or 9 teaspoons per day, for men.
Vitamin D and potassium were added to in 2016. These new additions are nutrients that Americans don鈥檛 get enough of, according to the FDA.
鈥淰itamin D and calcium are needed to support bone health, and consuming adequate amounts can reduce the risk of osteoporosis,鈥 Lopez says. 鈥淚ron is necessary for blood cells to carry oxygen around the body. Additionally, potassium helps regulate the heartbeat, nerve and muscle function and reduce risk of a stroke.鈥
The National Institutes of Health recommend 15 micrograms, or 600 international units (IU), of a day for adults, and 3,400 milligrams of a day for men and 2,600 milligrams for women.
Learning can be a useful tool in maintaining and improving your overall well-being. But Lopez also highlights the importance of understanding your own unique health needs.
鈥淓very individual person has unique nutritional needs that can be influenced by several factors such as activity level, genetics, age and food intake,鈥 she says. 鈥淚f you wish to learn more about nutrition or eating habits, speaking with a registered dietitian can provide you with guidance.鈥
