Why does the "Total Carbohydrates" section on food packaging never add up?

they don't add up because of complex carbohydrates (Polysaccharides), on some labels you might notice "Other Carbohydrates" and that usually is complex carbohydrates.

The number of calories *is* the total number of calories.  Calories only come from protein, fat, or carbs.  So listing the "calories from fat" is just telling you the fat calories.  If you add up the number of calories from protein, fat, and carbs, you should get the total number of calories- the number on the label after "calories."\n\nPcal + Fcal + Ccal = Total Calories.\n\nSo yes, that first calorie reading is what is contributing to your total calorie intake.  The rest just tell you what the calories consist of.

The answer to this is on below site along with quotes by MDs about why and about low glycemic index carbs etc.

My diabetic dietician said to have 45 carbs at each meal (breakfast, lunch & dinner) and two 15 carb snacks.  Now....I don't follow those instructions too well.

It is recommended that about 60% of your daily calorie intake be from carbs. The typical woman needs about 1700 calories/day and the typical man needs about 2000. That means a woman should have about 1020 carb calories and a man should have about 1200 calories from carbs. \n\nRemember, 40% of a food product's cals come from carbs.

U.S. Surgeon General C. Everett Koop in his 1988 Report on Nutrition and Health recommended reduction in four areas (fats and cholesterol, weight, sodium and alcohol). Only one area received a positive recommendation from the Surgeon General - "complex carbohydrates and fiber." The report says: "Increase consumption of whole grain foods and cereal products, vegetables (including dried beans and peas), and fruits."\n\nAccording to John Vanderveen, director of the division of nutrition at FDA's Center for Food Safety and Applied Nutrition, complex carbohydrates should make up about 55 percent of the calories in our daily diet, with fat making up 30 percent or less and protein the remainder. In an 1,800-calorie daily diet, that 55 percent represents about 250 grams of complex carbohydrates - nearly 1,000 calories.\n\nComplex carbohydrates, or polysaccharides, are made mostly of long strands of simple sugars. They are found in grains, fruits, legumes (peas and beans), and other vegetables. Complex carbohydrates include three types of dietary fiber - cellulose, hemicellulose and gums - and starches.\n\nA single starch molecule may contain from 300 to 1,000 or more sugar units. The giant molecules are packed side by side in a plant root or seed, providing energy for the plant.\n\nAll starches are plant materials. Cereal grains, such as wheat, rice and corn, are rich sources of starch, constituting a large part of the world's food supply, generally in the form of breads and pastas. Starches are also found in potatoes and legumes.\n\nStarchy foods, once avoided by dieters as fattening, are actually a good source of energy for those who want to lose weight. Many people think that starchy foods such as bread, potatoes and pasta are high in calories. They aren't - until the bread is thickly buttered, the potatoes generously topped with sour cream, and the macaroni mixed with cream and cheese sauce. Starches (and proteins) provide only four calories per gram, while fat provides nine calories per gram. Without the toppings, or with only moderate amounts, complex carbohydrate foods can be less fattening than animal-protein foods that naturally contain fat.\n\nWhat's more, a diet high in carbohydrates just may be more slimming than a diet of comparable calories that is high in fat. Studies still are preliminary, but a research report published in the January 1989 American Journal of Clinical Nutrition suggested that "altering the composition of the diet in favor of a higher carbohydrate-to-fat ratio may decrease the incidence of obesity." The researchers also found that when the participants switched to a diet high in complex carbohydrates, they became full more quickly and unconsciously decreased their caloric intake. :-)

Read the portion of the label that says 'calories per serving' first and make your decision based on that.  If you have only fat, protein and carbohydrate to consider and you want to make it so it contains 50% less fat then the other two have to increase to make up the 100%.  Generally, you are better off consuming less of the regular product, than using a low-fat variety.

Check the carb content on the label...you'll be surprised how much sugar is in it!

beaver is right. a side point seeing as how it looks like a chemistry class question....\n CARBO HYDRATE contains C H O in a 1:2:1 ratio.

Calories come from various sources...  protein (meats, poultry, fish, cheeses, etc.), carbohydrate (fruits, vegetables and grains), fat (olive oil, margarine, butter).  All calories "count" but eating a high percentage of your calories from fat, regardless of the type, is unhealthy unless you're on a low-carb diet.\n\nMany people say, "A calorie is a calorie," but of late they are finding that protein calories burn differently than processed carbohydrate calories.  People attempting to lose weight find they do better by eating fewer "white" carbohydrates like bread, potatoes, pasta and rice because your blood sugar level stays more stable.

There are many websites that you can just type the food in. They call them "Calorie Calculators"

Since no has taken a stab at this yet, I'll try:\n\n  As an experiment, food was first cooked (to kill germs)\nand then stored in air-tight bottles. It was taken aboard an \nEnglish ship. After a couple of months the bottle was opened\nand the food was found not to have spoiled.\n  A sheet metal worker found out about this, and thought \nabout storing food in cans instead. James Burke discusses \nthis in one of the Connections Programs. I've included a \nlink in the sources part.\n  There is no reason the surface area of the can would vary\nbetween now and then unless the cans were first made with \na square bottom. I don't believe it was.

Simply watch your carbohydrate intake.Look at the labels(yes I know that's boring)But,just once look at the container say on a soda pop can,what do you see? Most likely on that one can you will find from40-50 carbs.just on one can of soda pop.Your body was not made to process all the carbs it's most likely getting in one day. Try drinking only water as your beverage for a week or two and see what happens. How many carbs will you not get just by checking this one item.Then after a few weeks,start checking the containers of food you buy.Now look on the side of the can or box,how many carbs in in this item per serving? Cut back your carbs and you will most likely lose weight.

This is a tricky question. You really need to talk to a nutritionist because everyone has different needs.

It has nothing to do about carbs it's all about your calorie intake.  dont listen to anyone else
