3. Plan a diet/meal plan for one day using all of the recommended servings and food groups from MyPlate for 2000 calorie

Answers

Answer: mark me as brainliest

Explanation:

A balanced diet is one that fulfills all of a person’s nutritional needs. Humans need a certain amount of calories and nutrients to stay healthy.

A balanced diet provides all the nutrients a person requires, without going over the recommended daily calorie intake.

By eating a balanced diet, people can get the nutrients and calories they need and avoid eating junk food, or food without nutritional value.

The United States Department of Agriculture (USDA) used to recommend following a food pyramid. However, as nutritional science has changed, they now recommend eating foods from the five groups and building a balanced plate.

According to the USDA’s recommendations, half of a person’s plate should consist of fruits and vegetables.

The other half should be made up of grains and protein.

Why do teens need to eat more from the grains, fruits and vegetables food groups?

Answers

Answer:

Each group of foods (grains, fruits, and vegetables) enable teens to grow healthily, as these foods provide the sufficient nutrients and vitamins needed to do so. Grains provide fiber, b vitamins, and minerals, reducing the chances of becoming chronically ill. Vegetables and fruits are natural sources that provide essential vitamins for humans to live and grow (such as vitamin a and vitamin c). Vegetables and fruits are rich in these nutrients, as they help maintain a healthy blood pressure, their dietary fibers lowering the risks of heart disease, and also maintains (or boosts even) the health of our eyes, skin, and other essential parts of the body as well.

Calla sees her 10 year old sister choking. She does the five-and-five approach. What did Calla do?

Answers

Answer:

5 back blows, 5 abdominal thrusts, and perhaps alternated between the two

Explanation:

Firstly, when should we do the five-and-five approach?

It is highly recommended to the five-and-five approach when the person choking cannot forcefully make themselves laugh, talk, etc.

Steps of the Approach:

Step 1: Give 5 back blows

           - if the person choking is an adult, stand to the side and right behind

           - if the person choking is a child, kneel down behind them

           - put an arm across the adult or child's chest

           - bend the person over at the waist

           - give five separate back blows (hit them strongly ) between the person's shoulder blades with your hand's heel

In this case, Calla's sister is 10 year old, meaning she kneels down behind her. Calla put her arm across her sister's chest for support, and then she bended her over at her waist. After that, Calla firmly hit her sister in the back between her shoulder blades with the heel of her hands.

Step 2: Give 5 abdominal thrusts

            (for children)

           - put your arms under the child's arms and around the upper bit of their abdomen

           - clench one of your fists and place it between their ribs and the navel

           - grip this clenched fist with your other hand and pull sharply inwards and upwards five times

           (for adults)

           - put your arms around their waist then bend them forward

           - clench one of your fists and place it above the adult's belly button

           - grip this clenched fist with your other hand and pull sharply inwards and upwards five times

Again, in this case, Calla's sister is a child. Calla put her arms under her sister's arms and around the upper bit of her abdomen. She clenched one fist and placed it between her sister's ribs and navel. She grasped the fist with her other hand sharply pulled inward and upward five times.

 Step 3: Alternate between the five back blows and abdominal thrusts

             - Do the procedures listed above alternatingly until the blockage

            is cleared and the adult or child stops choking

Calla gave her sister 5 back blows and 5 abdominal thrusts alternatingly until she finally got her sister to stop choking. Additionally, the blockage was removed.
