Read The Following Information Before Completing the Lab Assignment

Read the following information before completing the lab assignment. How to Read Nutrition Facts Labels Understanding food labels can help you make wise choices—if you know what to look for. Here's a rundown of the most important elements.

Serving Size: This number is at the top for a reason: The nutritional information on the rest of the label applies to one serving. The FDA sets serving sizes for all foods—they are measurements, not recommendations. Total calories are calculated per serving, as are total calories from fat, so be sure to look at the servings per container. For example, a bag of potato chips might say it has 150 calories per serving, but the entire bag might be three servings, or 450 calories.

Percent of Daily Value: This is calculated for a moderately active woman, or a fairly sedentary man, who eats 2,000 calories a day. (Highly active women, moderately active men, and growing teen boys may need closer to 2,500 calories a day.) A serving of Cheerios with ½ cup of skim milk gives the average adult just 3 percent of the daily value of fat intake and 11 percent of the daily value of fiber intake recommended by the USDA.

Fat: More important than total fat are the numbers for saturated, polyunsaturated, monounsaturated, and trans fats. You want to see that the food contains relatively little saturated fat and trans fat, and relatively more polyunsaturated and monounsaturated. Keep in mind that "fat-free" doesn't equal "calorie-free." Many fat-free and low-fat foods have added sugar.

Cholesterol: This is a fat-like chemical that's an essential component of cell membranes, a covering for nerve-cell fibers, and a building block of hormones. Only animal products contain cholesterol. Adults are advised to limit their daily intake to 300 milligrams. Too much can elevate your blood cholesterol, raising your heart-disease risk.

Sodium: The recommended daily limit for an average adult is 2,300 milligrams; too much sodium can cause high blood pressure. A food is considered low in sodium if it contains no more than 140 milligrams. For example, a serving of Cheerios has 210 milligrams and is therefore not low in sodium. A single serving of soup or a frozen meal may contain 1,000 milligrams or more of sodium, which is nearly half the daily limit.

Potassium: Getting enough of this mineral—4,700 milligrams a day for adults—may help prevent high blood pressure. Low potassium levels can lead to an irregular heartbeat.

Total Carbohydrate: This large category includes everything from healthy carbs like whole grains to unhealthy refined carbs like sugar. It's most helpful to look at the sugar and fiber numbers.

Dietary Fiber: The average adult should eat between 21 and 35 grams of fiber daily, but most don't reach that level. When buying bread or cereal, look for a brand with 3 grams or more per serving. Fiber can be soluble or insoluble—both are important. Soluble fiber, found in oatmeal, barley, and dried beans, can help lower cholesterol levels. Insoluble fiber, found in whole grains and fruit and vegetable skins, supports digestion and prevents bowel disorders.

Sugars: These simple carbohydrates include glucose, dextrose, fructose, and galactose, which provide little nutritional value. Sugar can be hidden in crackers, "healthy" cereals, and salad dressings as added flavor.

Protein: The general recommendation is 0.45 grams of protein daily per pound of body weight (for example, 68 grams for a 150-pound person). Most Americans get enough protein effortlessly, and it's rare to consume too much on a normal diet.

Vitamins and Minerals: Food labels list naturally occurring and added vitamins and minerals, along with the percentage of daily value based on a 2,000-calorie diet. The footnote (not always present) provides recommended daily totals for fat, cholesterol, sodium, potassium, carbohydrates, and fiber.

Ingredients: Ingredients are listed in order of quantity, with the major ones first. For example, in bread, you want "whole wheat" or "oats" to be the first ingredient. Note that "whole wheat" means "whole grain," but not all "multigrain" or brown-colored breads are made of whole grain.

Part I: Analyzing Nutrition Labels

Understanding nutrition labels is essential for making informed dietary choices. The labels provide critical information about the nutrient content, serving size, and ingredients of packaged foods. This knowledge helps consumers evaluate the healthiness of their food, manage dietary restrictions, and maintain balanced nutrition.

In practice, reading food labels involves inspecting various components like calories, fats, sodium, sugars, fiber, proteins, and vitamins. For example, a typical snack food such as potato chips may list a serving size of 28 grams (about 15 chips). It’s common for individuals to consume larger portions, so they should adjust their calorie and nutrient intake accordingly. The label might report 150 calories per serving, but if someone eats 30 chips (roughly double the serving size), their calorie intake would also double to 300 calories.

Ingredients are listed in descending order by weight, providing insight into the food’s composition. Leading ingredients in snack foods often include processed oils, refined flours, and flavorings. Analyzing these ingredients helps determine their nutritional contributions and potential health impacts. For example, snack foods high in trans fats or saturated fats are less healthy, whereas those with whole grains or nuts offer more nutritional benefits.

Evaluating the nutrition panel, paying attention to the amounts of total fat, saturated fat, trans fats, and sodium is crucial. Excessive trans fats and saturated fats increase the risk of cardiovascular disease, while high sodium intake is linked to high blood pressure. For example, if a snack contains 10 grams of total fat, 3 grams of saturated fat, and 200 milligrams of sodium per serving, it should be consumed in moderation.

Assessing vitamins and minerals, some snack foods are fortified with nutrients like vitamin D or calcium. While not all snacks provide significant vitamins, some fortified options can contribute to daily requirements. Overall, snack foods often offer limited nutritional value and should be complemented with a balanced diet rich in fruits, vegetables, and whole grains.

Part II: Analyzing a Sweet Food Item

Applying similar principles to a sweet food, such as candy or chocolate, involves examining the ingredient list and nutrition facts. For example, a chocolate bar might have a serving size of 40 grams, with 210 calories, 12 grams of fat, and 20 grams of sugar. The main ingredients usually include sugar, cocoa solids, and milk solids. Such foods are high in sugars and fats and generally low in essential nutrients, making them enjoyable in moderation rather than staples of a diet. Excessive consumption of sugary foods can lead to weight gain and increased risk of metabolic diseases.

In conclusion, reading nutrition labels equips individuals to make healthier choices, avoid excess intake of harmful nutrients, and foster balanced nutrition. While snack and sweet foods can be enjoyed occasionally, understanding their nutrient content helps to maintain overall health and prevent diet-related illnesses.
