Alright this W A Y back to health class in middle school/high school. Did you have a unit on nutrition? Was a nutrition label briefly explained (primarily its location). Now that you are older, wiser and concerned about your health and nutrition, knowing how to look at a nutrition label and really understand the different components and how they are calculated is you NEXT step in building a lifestyle based off macro nutrition.
Below is a sample nutrition guide for Quaker Granola. I have provided some explanations on side for your reference.
Serving Size
This number determines the amount of all the other nutrients included in the label. The first thing you should know and should always keep in the back of your mind is that this number is derived from the manufacturer. That means that 1 serving does not necessarily mean that you should eat the entire manufacturer serving. For example, a serving of Quaker Granola is 1/2 cup. That is A LOT of granola in terms of nutrients. An actual serving for a meal plan would likely be 2 Tbs (or 1/4 cup). So the manufacturer's serving has 1/2 a cup but really a typically serving would be 1/4 cup. Let's see how that would change the calories for the Quaker Granola:
1/2 cup = 237 calories
1/4 cup= 118.65calories
Calories
Think of calories as energy. In order to sustain your everyday activities you must consume enough calories throughout your day. The amount of calories is determined on your current weight, your overall goal (weight loss, gain or maintain) and your activity level. The calories are the SUM of all the nutrients (per serving).
You should know that there are
4 calories per gram of PROTEIN and CARBOHYDRATE
9 calories per gram of FAT
There is also a not so noticeable "calories from fat". Discussion on fat below but note that this number includes all types of fats; healthy and not so healthy.
Fats
Not the route of all evil, fats get a BAD wrap. A well balanced diet requires fats just making sure the right kind. You will noticed that there are multiple listed.
Saturated fats- are directly linked to your cholesterol. The higher amount of saturated fats the higher level of cholesterol (LDL- low density lipoprotein). According to the American Heart Association elevated amount of saturated fats and high levels of cholesterol can lead to a greater risk of heart disease and stroke. Saturated fats will solidify when at room temperature. These are considered "unhealthy fats" and should be limited to less than 7% of your daily fat allowance. Common sources are fatty proteins (beef, lamb, poultry), lard, cheese, and butter.
Unsaturated fats- also listed as Polyunsaturated and Monounsaturated fats, are considered healthy and are what the majority of your daily fat percentage should come from. Common sources are nuts, vegetable oils, and fish. There are no guidelines on how much of polyunsaturated and monounsaturated fats you should consume so rule of thumb stick within your daily fat allowance. Switch up your cooking methods to use olive or coconut oils instead of saturated fats like Crisco. \
Trans fats- come from two primary sources, naturally in small amounts of animal and dairy fats (CDC, 2014) and artificially manufactured. Although the natural source is hard to avoid, the artificial source caused much up roar in the US recently. Trans fat is cheap to manufacture and increased the life shelf of processed foods. Manufacturers were being pressured to lower their use of trans fat and some states even mandated that restaurants and other foods service industries restrict the use (CDC, 2014). The common culprits of trans fat are fried foods, cake, cookies, over processed foods (frozen pizzas), coffee creamers, etc.
Carbohydrates
My FAVORITE nutrient but also one that I am sensitive to. Consuming carbs provided glucose to the body which is transformed into energy. Well if we need lots of energy than we should eat LOTS of carbs, right? WRONG! Although they are trafmorned into energy if the energy is NOT used than they are reverted to fat. So, determining your carbohydrate intake should be based on how active you are! Carbohydrates are broken down into two categories
Complex- aka good carbs
Starches- must be digested before it can be transformed into glucose. Starch are found in vegetables, breads and grains
Dietary Fiber- is indigestible and is found in vegetables, fruits and whole grain. it is recommended that you get 14g per 1,000 calories consumed (CDC, 2014).
Simple- also referred to as bad carbs. Naturally or manufactured, sugars should be carefully watched.
Sugars- Those commonly used are refined sugar, corn syrup, glucose, honey, fruit juice concentrate, lactose, dextrose, fructose, etc. No true nutritional value, sugars are immediately reverted to fat in the body.
Protein
Every cell in our body consists of protein! Constantly in a state of damage and repair, proteins are digested into amino acids which aid in this damage/repair process. Protein can be found in meat, tofu, eggs, nuts/seeds, milk and milk products. A complete source of protein would be one that provides you with all the essential amino acids. An incomplete source has lower amino acid profile. Recommended amount depends again on your activity level. The CDC has a great chart that provides approximate amount based on age and gender,
