There are six classes of nutrients. Name the three that supply energy. ✔✔Carbohydrates, proteins

Explain the differences between hunger and appetite. ✔✔Hunger is the internal drive to find and
eat food. It is often experienced as a negative sensation. Appetite is the external drive that encourages us to find and eat food. It is related to pleasant sensations associated with food.
Describe in detail the role that the hypothalamus plays in determining whether or not you feel
like eating. ✔✔When we have not eaten for a period of time, the amount of nutrients in the blood
begin to decline. This drop stimulates the feeding center in the hypothalamus which signals us to eat. When the nutrient level of the blood begin to rise, the satiety center is activated and our desire to continue to eat declines.
Name the four types of external forces that influence our eating habits and patterns and give an
example of how you experience each in your life. ✔✔1. Sensory: Includes how foods affect our
senses such as the way it tastes, smells, and feels. For me, I love spicy and sweet foods so those scents such as baking cinnamon rolls or Thai curries trigger the desire to consume nutrients even when I don't necessarily need to eat.
- Cognitive: Includes the influences of advertising, social factors, comfort foods, and our habitats. For example, protein is advertised as being good for energy and muscle health especially when doing physical activities such as hiking. When my family goes on a hike, I am now more likely to pack a protein bar or boiled egg for a snack rather than a cookie and gummy candies.
- Environmental: Includes factors such as our lifestyle, economic standing, cultural influences, and environment or what is available to us. Here in Hawaii, we grow up eating poi made from mashed kalo corms. If you haven't grown up with it, there is a much higher possibility that you won't love it or even eat it later in life. Culturally it is significant because the kalo was a relative to Hawaiian people and was a main nutritional force. Another example of environmental force would be seasonal fruits and vegetables. When it is summer and the mango and lychee are in full swing, there is a much bigger probability that I'll eat it because it is free from friends and family or available at a much cheaper price than if it was off-season and the prices were driven way up.
- Health Status: Includes factors such as age and gender, your physical condition, and anything disease-related that puts restrictions on what you can consume, and even things like how aging can alter your tastebuds. In my family, we have relatives with different health issues. When we
Under-nutrition occurs when nutrient intake does not meet nutrient needs and over time health begins to decline.
Given the nutritional label shown below, how many milligrams of sodium will you consume if you ate the entire container of macaroni and cheese?
470 ml per serving
there are 2 servings in a box ✔✔470 mg per serving x 2 servings per container = 940 mg
Name the key hormone that causes a feeling of satiety. Indicate where in the body it is produced
and the process by which it operates. ✔✔Leptin is produced by the fat cells which are also
known as adipose tissue. The role of leptin is to alert the brain to turn off the hunger center and activate the satiety center when consuming a meal.
