However simply since you’re watching your calorie consumption does not essentially imply you are maintaining a healthy diet and getting the vitamins you want. We’ll dispel the myths that energy are equal and supply examples of how the meals selections you make matter.

Why is the supply of energy necessary?

In 2010, a narrative a few diet professor at Kansas State making nationwide information for shedding pounds on a Twinkie weight loss program. He misplaced 27 kilos over two months, with two-thirds of his day by day calorie consumption coming from Twinkies, chips, sugary cereals and different processed baked items.

Cookies and chips present no dietary worth past energy. As compared, carrots are excessive in vitamin A and amino acids (cysteine ​​and threonine), whereas mushrooms are a superb supply of copper, selenium, vitamin B2 (riboflavin), vitamin B3 (niacin) and vitamin B5.

Even within the case of pure meals, this idea nonetheless applies. Apples are a superb instance of this. Consuming a big apple has 116 energy in comparison with 113 energy for a cup (8 ounces) of apple juice. The apple juice is the higher selection as a result of it has 3 fewer energy, proper? Improper.

Let’s examine. The apple in its entire unprocessed type has 5 grams of dietary fiber and 17 p.c of the advisable day by day worth of vitamin C.
