How should you use a heart rate monitor
12345 [234]
 Measure your heart rate before, during and after work outs and write it down. Monitors can be worn as a strap across the chest, on the wrist and even on the head, and by measuring your heart rate can help you exercise at the right intensity. Most don't have a display, so you'll need to connect your monitor with a sports watch or smartphone app to see your heart rate.

Which individual is making a food choice based on values? a. A child who spits out his mashed potatoes because they taste too sa
Arturiano [62]

Answer:

C. A Catholic woman who fasts on Good Friday to honor religious custom.

Explanation:

Today, many people carefully consider what they eat before consuming it according to his or her values, in contrast to choosing what to eat only by cravings or 'superficial' decisions. For example, choosing to consume less meat due to the impacts that the meat industry has in our climate is a decision someone makes in regard to values, not only nutrition. So, there is much more analysis involved in this type of decisions.

In this scenario, a Catholic woman decides to fast on Good Friday because she is honoring her religion. This is not a nutrition or health choice, this is a conscious decision based on her values. On the other hand, the other options refer to decisions they make in regard to taste, cravings, or diet.
