Question

What type of data supports the finding that the fatty acids in avocados and cashews are "good fat," whereas the fatty acids in donuts and fried chicken are "bad fat?

Short answer

Answer: The data that supports this claim includes the fatty acid composition of these foods, which can be found in peer-reviewed studies or reputable sources like the USDA National Nutrient Database. This data shows that avocados and cashews primarily contain monounsaturated and polyunsaturated fats (good fats), while donuts and fried chicken contain saturated and potentially trans fats (bad fats). Comparing the proportions of good and bad fats in these foods, along with understanding their health implications, provides evidence to support the claim.

Step-by-step solution

Identify the types of fats in avocados, cashews, donuts, and fried chicken

We need to first understand which fats are considered good and bad. Unsaturated fats, like monounsaturated and polyunsaturated fats, are generally considered as "good fats" because they help improve blood cholesterol levels and provide essential fatty acids. Saturated and trans fats, also known as "bad fats," can lead to high cholesterol levels and increase the risk of cardiovascular diseases. Avocados and cashews mostly contain monounsaturated and polyunsaturated fats, respectively. On the other hand, donuts and fried chicken contain saturated fats and possibly trans fats, depending on the type of oil used for frying.

Present data on the fatty acid composition of the foods

To support the claim, we can provide data about the fatty acid composition of these foods. This data can come from peer-reviewed studies or reputable sources, such as the USDA National Nutrient Database. For example, we can show that: - An avocado (150g) contains about 21g of total fat, of which 2.7g are saturated fats, 13.3g are monounsaturated fats, and 2.5g are polyunsaturated fats. - A 1-ounce serving of cashews (28g) contains about 12g of total fat, of which 2.2g are saturated fats, 7g are monounsaturated fats, and 2.2g are polyunsaturated fats. - A plain donut (45g) contains about 11g of total fat, of which 4.6g are saturated fats and 5.8g are monounsaturated fats. It may also contain trans fats if it is fried in hydrogenated oils. - A piece of fried chicken (140g) contains about 13g of total fat, of which 3.5g are saturated fats, 5.5g are monounsaturated fats, and 3g are polyunsaturated fats. If cooked in hydrogenated oils, it may also contain trans fats.

Compare the proportions of good and bad fats

From the data presented, we can compare the proportions of good fats (monounsaturated and polyunsaturated fats) and bad fats (saturated and trans fats) in these foods. For avocados and cashews, the majority of their fat content is made up of monounsaturated and polyunsaturated fats. In contrast, donuts and fried chicken have higher proportions of saturated fats, and potentially trans fats, which are considered bad for our health.

Explain the health implications of these fats

Finally, the data supports the finding that avocados and cashews contain high amounts of "good fats," which can improve blood cholesterol levels, decrease inflammation, and provide essential nutrients. On the other hand, donuts and fried chicken contain higher proportions of "bad fats," which are associated with increased cholesterol levels and a higher risk of cardiovascular diseases.
