Discussion Dates: June 1 - June 7, 2020 Using the following links: and . I'd like you to watch the animations of high blood sugar and low blood sugar. Once you've viewed these animations, please explain how carbohydrates can impair your health. There are many options that can be discussed. Please have data to support your discussion.

Discuss what dietary fats do for the human body. How much fat is recommended in our daily dietary intake? Look up how much fat is in three of your favorite foods and post the fat content here. Is all protein the same? Let's turn our attention to the different forms of protein available to us.

People who lift weights will very often increase their protein intake considerably via protein supplements and protein bars. Vegetarians limit their protein intake to varying degrees. So what does all this mean? What are essential and non-essential amino acids? How do we maintain health status and normal physiological reactions without exceeding our protein needs?

Is animal protein the only "available" source? What would you recommend?

Understanding the relationship between diet and health is critical in promoting optimal well-being and preventing disease. This essay examines key nutritional components—carbohydrates, fats, and proteins—by analyzing their impacts, recommended intakes, and sources, supported by current scientific data.

The Effects of Carbohydrates on Health

Carbohydrates are a primary energy source for humans, fueling vital physiological processes. However, excessive consumption, especially of refined sugars, can lead to adverse health outcomes such as obesity, insulin resistance, and type 2 diabetes (Hu, 2013). Animations illustrating high and low blood sugar levels visually demonstrate how carbohydrate ingestion influences blood glucose regulation. High blood sugar, resulting from rapid carbohydrate digestion, can overstimulate insulin response, contributing to metabolic disturbances (Kahn et al., 2014). Conversely, low blood sugar episodes can cause dizziness, weakness, and impaired cognitive function.

The impairment of health by carbohydrates is particularly evident when dietary patterns favor high glycemic index foods, which cause sharp rises and falls in blood glucose levels. Chronic overconsumption of such foods has been linked to increased risk of cardiovascular disease (Willet et al., 2004). Data from the American Diabetes Association indicates that managing carbohydrate intake—focusing on complex carbohydrates and fiber—can mitigate these risks and support metabolic health.

Role of Dietary Fats in Human Nutrition

Fats are vital for numerous bodily functions: they serve as energy reserves, building blocks for cell membranes, and precursors to hormones like corticosteroids and sex hormones (Gillingham et al., 2011). The Dietary Guidelines for Americans recommend that 20-35% of daily calories come from fats, emphasizing the consumption of healthy unsaturated fats while limiting saturated and trans fats (USDA, 2020).

To contextualize fat content, three common foods were analyzed: a cheeseburger, a slice of avocado, and a handful of almonds. A typical cheeseburger can contain approximately 30 grams of fat, predominantly saturated fat; a medium avocado provides about 15 grams, mainly monounsaturated fats; and a quarter cup of almonds offers roughly 14 grams of mostly unsaturated fats. These examples highlight the variability in fat content and quality among different foods.

Protein: Types, Sources, and Nutritional Significance

Not all proteins are identical; they differ in amino acid composition and bioavailability. Proteins are made up of amino acids, some of which are essential—meaning they must be obtained from the diet—while others are non-essential, synthesized by the body (Wu, 2013). Maintaining health requires a balanced intake of both types, especially in populations with increased needs, such as athletes or vegetarians.

Protein requirements vary based on age, activity level, and physiological state but generally fall between 0.8 grams per kilogram of body weight for sedentary adults (WHO, 2007). Excessive protein intake, especially from animal sources, can strain renal function and contribute to other metabolic issues (Bender, 2009).

Sources of Protein: Animal and Plant-Based Options

Animal proteins—meat, dairy, fish, and eggs—are complete proteins, providing all essential amino acids. However, plant-based sources such as beans, lentils, tofu, and seeds can also meet protein needs when consumed in varied combinations to ensure amino acid completeness (M source, 2014). For vegetarians and vegans, a varied diet emphasizing legumes, grains, nuts, and seeds can adequately supply necessary amino acids.

Given the environmental concerns associated with animal agriculture, plant-based proteins are increasingly recommended. They not only support health but also promote sustainability. For example, a diet emphasizing soy, quinoa, and leguminous vegetables can meet protein demands effectively (Rizzo & Chieppa, 2020).

Conclusion

Optimal health depends on a balanced intake of macronutrients—carbohydrates, fats, and proteins—each playing essential roles. Understanding their functions, sources, and impacts enables informed dietary choices. While fats and proteins can be derived from diverse sources, attention to quality and quantity is vital for maintaining health and preventing chronic diseases. Incorporating adequate fiber, healthy fats, and complete plant-based proteins supports physiological functions and aligns with sustainable nutritional practices.
