Terms in this Study Set(64)
Omega-3 Fatty Acids(16)
What are Omega-3 fatty acids?
Essential fatty acids important for human health, found in fish and certain plants.
EPA
Eicosapentaenoic acid; supports heart health and reduces inflammation.
DHA
Docosahexaenoic acid; crucial for brain development and function.
ALA
Alpha-linolenic acid; plant-based Omega-3 found in flaxseeds and walnuts.

EPA vs DHA
EPA: Focuses on heart health; DHA: Critical for brain and eye health.
Fill in the blank: Omega-3 fatty acids can help reduce ________.
inflammation.
What health effect is linked to Omega-3 consumption?
Reduced risk of cardiovascular diseases and improved mental health.
Sources of EPA and DHA
Fatty fish (salmon, mackerel), fish oil supplements.
Role of Omega-3s in brain health
Supports cognitive function and may reduce mental decline.
True or False: ALA can be converted to EPA and DHA.
True; although conversion rates are low.
Why are Omega-3s considered anti-inflammatory?
They inhibit inflammatory pathways in the body, improving overall health.
Recommended intake of Omega-3s
250-500 mg of EPA and DHA combined per day for adults.
Omega-3 supplements: Pros & Cons
Pros: Convenient source; Cons: Possible contaminants in fish oil.
What are omega-3 fatty acids primarily used for in the body?
Cell membrane structure, energy production, and hormone synthesis.
Effects of Omega-3 deficiency

Types of Dietary Fats(16)
Saturated Fat
A type of fat found in animal products and some plant oils. Solid at room temperature. Examples: butter, cheese, and coconut oil.
Unsaturated Fat
These fats are typically liquid at room temperature. They are divided into monounsaturated and polyunsaturated fats. Examples include olive oil and fish oil.
Trans Fat
Artificially created through hydrogenation to solidify liquid oils. Associated with negative health effects, such as increased heart disease risk.
Monounsaturated Fat
A type of unsaturated fat with one double bond. Found in olive oil, avocados, and nuts. Can improve cholesterol levels.
Polyunsaturated Fat
Contains multiple double bonds in its structure. Includes Omega-3 and Omega-6 fatty acids, crucial for brain function.
Omega-6 Fatty Acids vs. Omega-3
Omega-6 is pro-inflammatory; Omega-3 is anti-inflammatory. Both are essential but should be consumed in balance.
Fill in the blank: Most unsaturated fats are __________ at room temperature.
liquid
True or False: Saturated fats are generally healthier than unsaturated fats.
False. Unsaturated fats are typically considered healthier due to their benefits for heart health.
Healthier options for cooking?
Use olive oil or avocado oil instead of butter or lard for better health outcomes.
What do trans fats do to cholesterol?
They raise bad cholesterol (LDL) and lower good cholesterol (HDL), increasing heart disease risk.
Sources of Monounsaturated Fats
- Olive oil - Canola oil - Nuts - Avocados
Which type of fat can improve heart health?
Unsaturated fats, particularly monounsaturated and polyunsaturated fats.

Fill in the blank: Trans fats are often found in __________ foods.
processed
What is a characteristic of polyunsaturated fats?
They remain liquid at room temperature and include essential fatty acids like Omega-3.
True or False: All dietary fats are unhealthy.
False. Some fats are essential and beneficial for health.
Health Implications(16)
Unsaturated fats impact heart health positively.
They help reduce LDL (bad) cholesterol levels, which lowers the risk of heart disease.
True or False: Saturated fats are always harmful.
False. While excessive intake is linked to health risks, moderate consumption in a balanced diet may not be detrimental.
Omega-3 fatty acids reduce inflammation.
They lower the production of inflammatory molecules, which can help alleviate symptoms of chronic diseases.
Fill in the blank: Trans fats increase ____ cholesterol levels.
LDL (bad) cholesterol.
Question: How do monounsaturated fats affect health?
They can help reduce total cholesterol and lower the risk of heart disease.
Comparison: Omega-3 vs. Omega-6.
Omega-3s reduce inflammation, while Omega-6s can promote it if consumed in excess.
Health effect of trans fats?
They increase the risk of heart disease and stroke by raising LDL cholesterol.
What is the role of polyunsaturated fats?
They are essential for brain function and cell growth; sources include fish and walnuts.
Cause: High saturated fat intake → Effect?
May lead to increased cholesterol levels and a higher risk of cardiovascular diseases.
Trans fats are found in ____ foods.
Processed snacks, baked goods, and fast foods.
True or False: Omega-3s are not essential fatty acids.
False. Omega-3s are essential as the body cannot synthesize them.
Key health benefit of omega-3 fatty acids?
They support cognitive function and may reduce the risk of Alzheimer's disease.
What impact do dietary fats have on insulin sensitivity?
Healthy fats, like omega-3s, can improve insulin sensitivity, aiding glucose metabolism.
Saturated fats vs. Unsaturated fats: Which is better?
Unsaturated fats are generally healthier, promoting better heart health.
Health risks associated with high trans fat consumption?
Heart disease, stroke, and type 2 diabetes.
What do essential fatty acids do?
They are vital for the body's functions and must be obtained through diet.
