- Saturated Fats: ~7%
- Polyunsaturated Fats: ~31%
- Omega-3 Fatty Acids: Alpha-linolenic acid (ALA)
Walnut Oil
Walnut oil is a specialty oil prized for its high omega-3 content. It's best used in salads and cold dishes to preserve its delicate flavor and nutritional properties. Regular consumption of walnut oil can support heart health and reduce inflammation.

Factors to Consider When Choosing a Cooking Oil
Smoke Point
The smoke point of an oil is the temperature at which it begins to smoke and break down, producing harmful compounds. Different cooking methods require oils with varying smoke points:
- High Smoke Point Oils: Avocado oil, canola oil, refined olive oil
- Medium Smoke Point Oils: Extra virgin olive oil, coconut oil
- Low Smoke Point Oils: Flaxseed oil, walnut oil
Fat Composition
The type of fats in cooking oils can impact health differently:
- Monounsaturated Fats: Found in olive oil, avocado oil, and canola oil; beneficial for heart health.
- Polyunsaturated Fats: Present in walnut oil, flaxseed oil, and sunflower oil; essential for brain function and reducing inflammation.
- Saturated Fats: High in coconut oil and animal fats; should be consumed in moderation.
Nutritional Content
Some oils offer additional nutritional benefits, such as vitamins and antioxidants:
- Vitamin E: Present in olive oil, avocado oil, and sunflower oil; supports skin health and immune function.
- Antioxidants: Found in extra virgin olive oil; help combat oxidative stress.
- Omega-3 Fatty Acids: Present in walnut oil and flaxseed oil; essential for heart and brain health.
The choice of cooking oil can significantly impact your overall health. While each type of oil has its benefits, factors such as fat composition, smoke point, and nutritional content should guide your decision. The healthiest oils, including olive oil, avocado oil, and walnut oil, offer a balance of beneficial fats and essential nutrients. Ultimately, the best cooking oil for health depends on your specific dietary needs and cooking practices.

Single payer health care is a system in which a single public or quasi-public agency handles health care financing, but the delivery of care remains largely in private hands. Under this model, all residents receive health care services paid for by the government, typically funded through taxes, rather than private insurers. This contrasts sharply with multi-payer systems, where multiple insurance companies or health funds exist alongside government programs.
