Essential Nutrients In A Typical Protein Bar
Protein is crucial for the human body. It takes part in the action of forming, maintaining, and replacing cells. It is also one of three main sources of energy for everyday life activities and metabolism activities inside the body.
Lack of protein results in fatigue, sleepless, difficulty concentrating, and even life-threatening symptoms.
Redundancy of protein leads to a high level of ammonia that is harmful to your livers, a high level of saturated fat that is harmful to your heart. Too much protein also causes neurological impairment, obesity, and kidney stones.
Maintaining a right amount of protein absorbed every day is important. A 60-kg person needs about 60 grams of protein a day. Athletes, seniors, pregnant women, and those are injured need about 25% more protein.
Carb is the most important energy source to the human body, along with other two main energy sources - protein and lipid. It is also crucial for brain functions.
There are three main types of carbs that are important to the human body: Sugar, Starches, and Fiber. A typical adult should absorb about 135 grams of carb every day. Diabetics should eat less carb and pregnant women should ear more carb.
Fiber is a type of carbohydrate that our bodies cannot digest. As a result, fiber can move through the stomach, to the small and large intestine, and finally, move out the body while remaining relatively intact.
This process helps move food through the digestive system, promoting digestion, preventing constipation. Moreover, water-soluble fibers help reduce sugar levels and lower blood cholesterol.
Recommended fiber need is about 20g per day. Eating a sufficient amount of fiber reduces the risk of developing various diseases, including heart disease, diabetes, diverticular, and constipation. Eating too much fiber causes flatulence, bloating, poor absorption of some minerals, but absolutely not dangerous.
Sugar is not a healthy nutrient. It does provide us with energy and appetite, however, sugar promotes the aging process, slows down brain activities, and causes stress. So, reduce sugar in your diet.
In protein bars, there is also sugar alcohol, which is from fruits and herbs. Despite having alcohol in its name, sugar alcohol contains no ethanol (it's not alcohol). Not like man-made sugar, there are very few health problems related to sugar alcohol.
How To Choose The Best Protein Bars?
First, evaluate how much protein/carbs and other nutrients you need.
If you want a simple snack that doesn't have so many calories, a protein bar high in fiber, and low in protein and carbs would be the choice.
If you want to build muscles, you'll need a lot of protein and carbs.
If you are following a low carb diet, you should choose a bar that contains a large amount of protein but a small amount of net carb.
Then, you will want to make sure that the ingredients of the protein bar don't make you allergic. Common foods that lead to allergies are milk, soy, peanuts, and tree nuts.
Finally, it's about taste. Some might like sweet, some might like coconut, and some might like chocolate taste, it depends on you.
