What are calories and surprising facts about calories?
Surprising calorie Facts:
Surprising calorie facts are listed here briefly. The daily need for calories varies according to a person’s age, weight, gender and level of activity. Americans currently get more than 11% of their daily calories from fast food. High-energy, low-nutritional foods provide zero-calorie calories.
What are calories?
Most people associate calories only with food and drink, but anything that contains energy contains some calories. For example, each kilogram of coal contains 7 million kilocalories.
There are two types of calories:
- Small calories (calories): The amount of energy needed to raise the temperature of one gram of water by one degree Celsius.
- High calories (kilocalories): The amount of energy needed to raise the temperature of one kilogram of water by one degree Celsius.
Therefore, the use of terms large and small calories is misleading, and it is better to use numbers indicating the number of calories.
Daily need of calories
Studies show that the average need of a man is 2700 kcal (large calories) per day, and 2200 kcal (large calories) per day for women, although the daily need for calories varies from person to person according to several factors, the most important of which are:
- The general health of the body.
- The amount of daily physical activity.
- the weight.
- body shape.
Calories and body health
The human body needs calories to survive, without energy the cells of the body die, and the heart and lungs stop, and organs will not be able to carry out the basic vital processes necessary for life.
If a person consumes the same amount of calories he needs daily, this helps him to lead a healthy life. As for the low or high consumption of calories, he leads to many health problems.
Here are the caloric values found in the main food ingredients:
- 1 gram of carbohydrates: 4 kcal (large calorie).
- 1 gram of protein: 4 kcal (large calorie).
- 1 gram of fat: 9 kcal (large calorie).
For example, a cup of eggs weighing 243 grams contains:
Fat: 23.11 grams:
23.11 g x 9 calories = 207.99 calories.
Protein: 30.52 grams:
30.52 x 4 calories = 122.08 calories.
Carbohydrates: 1.75 g:
1.75 x 4 calories = 7 calories.
So 243 grams of pure eggs contain 347 calories: 208 fat, 122 protein, and 7 carbs.
Fast food in the lives of the American people
In 2013, CDC researchers published a report showing that 11.3% of calories consumed by Americans are from fast food. Nutrition and health care experts see this number as too high. As people age, they tend to get fewer daily calories from fast food, and this percentage drops to just 6% for older adults.
When should you eat?
Eating a delicious breakfast can help you consume more effectively, and eating time plays a role. A large breakfast with 700 kilocalories (large calories) is ideal for weight loss, and also helps reduce the risk of heart disease, diabetes and high blood cholesterol. A large breakfast helps you control weight, provided you adjust what you eat for the rest of the day.
This term refers to foods that provide energy but have very little nutritional value, as they do not contain dietary fibers, amino acids, antioxidants, minerals, or vitamins. Examples of these foods are fats (such as butter) and sugars added to foods (such as sweeteners). Added sugars and solid fats make foods and drinks more delicious and beautiful, but they are among the most dangerous causes of obesity.
Foods that contain large amounts of empty calories include:
- Solid fats and added sugars.
- Ice cream.
- Sweet cakes.
More than half of American adults consume at least one sugary drink per day, and 5% of them consume at least 567 kilocalories (kcal) per day of sugary drinks, equivalent to 4 cans of drinks.
