Fats add flavor to the foods you love. Yet, eating too many unhealthy fats, such as saturated fats, trans fats and cholesterol, can lead to health problems. Learn which foods contain these unhealthy fats and which ones contain fats that promote health in this lesson.
7. What is Digestion? - Definition & Process
This lesson will define the process of digestion. All parts of the gastrointestinal system will be discussed. Examples will be given when possible, and you'll have an opportunity to test your knowledge.
8. Small Intestine: Nutrient Absorption and Role In Digestion
The majority of digestion and absorption of nutrients takes place in the small intestine. In this lesson, you will learn about unique modifications within the walls of the small intestine, such as microvilli, villi, and circular folds. These structures increase absorption of nutrients.
9. Assimilation of Food in the Digestive System
In this lesson, we'll be learning about the biological process of assimilation and its role in the digestive system. We'll learn how this happens in humans and compare it to other animals.
10. Nutrient Deficiencies: Definition & Examples
In this lesson, we will explain what nutrient deficiencies are, and how deficiencies of certain vitamins and minerals occur. Next, we will review what problems are associated with these deficiencies.
11. What is Genetically Modified Food?
In this lesson, we will explore a recent advancement in agriculture known as genetic engineering. We'll look at how it's used to create genetically modified foods and also examine the advantages and disadvantages of these types of foods.
12. What Is Food Insecurity? - Definition, Impact & Prevention Efforts
Although every human on Earth has to eat to survive, the amount of food consumed varies a great deal by region. In this lesson, we will explore the concept of food insecurity and the issues that are causing it. We will also discuss prevention methods in place to try to combat food insecurity.
