Deep dives
Understanding Types of Fats
Fats are not all created equal, and an evolved understanding of their types categorizes them into good, bad, and ugly. Trans fats, found in fried products and baked goods, pose significant health risks and should be eliminated from the diet. Saturated fats, found in dairy and meat, should be consumed in moderation, while unsaturated fats from sources like nuts and olive oil are beneficial and essential for health. This nuanced view emphasizes the importance of fat balance in the diet to support cell function and vitamin absorption.
Health Effects of Vegetable Oils
Vegetable oils like sunflower and rapeseed are generally considered healthy options due to their high monounsaturated and polyunsaturated fat content. Contrary to some negative perceptions, these oils can reduce the risk of heart disease when they replace saturated fats in the diet. The message is clear: reducing saturated fats while increasing unsaturated fats leads to improved health outcomes. This highlights the need to rely on scientific evidence rather than popular myths when selecting cooking oils.
The Role of Olive Oil
Extra virgin olive oil is celebrated for its numerous health benefits, despite containing higher saturated fat than some other oils. Its health advantages come from its rich composition of monounsaturated fats, antioxidants, and polyphenols, which contribute positively to overall well-being. While concerns about smoking points and cooking temperatures exist, research indicates that olive oil remains a healthy choice even for cooking. Ultimately, olive oil should be part of a balanced diet where moderation and variety are key.
Debunking Cooking Oil Myths
Myths surrounding cooking oils, particularly claims that certain oils are unhealthy or should be avoided, often stem from misinformation. For instance, the belief that omega-6 rich seed oils are harmful contradicts evidence showing they can help lower heart disease risk when used in moderation. Additionally, oils like coconut oil, although high in saturated fat, contain beneficial compounds and can be used sparingly without negative health impacts. It is important for consumers to educate themselves about oils rather than rely on sensational claims found online.
Listener Sarah got in touch after seeing claims on social media that more expensive oils are better for you than regular vegetable, or rapeseed oil. And listener Kamal sent us a voicenote asking about coconut and avocado oil - both touted as healthier alternatives to other types of oil. Are they worth the extra cost? And what about health concerns if certain oils are overheated?
To get the answers Greg is joined by Professor of Population Health and Nutrition at the University of Cambridge, Nita Forouhi. Together they deep-dive into the studies and evidence, finding out what compounds constitute a healthy oil and giving advice on what we should be looking out for on the bottle.
