In the bustling world of cooking oils, peanut oil often finds itself overshadowed by the more glamorous options like olive, avocado, or coconut oil. But if you look past the hype, you’ll discover that this humble oil is an absolute powerhouse, packed with an incredible array of health benefits.
From boosting heart health to supporting weight management and beyond, peanut oil is a true unsung hero in the kitchen. In this article, we’ll explore the nutritional profile of peanut oil, its health benefits, and potential side effects.
What is Peanut Oil?
Peanut oil is derived from pressing peanuts, resulting in an oil that carries a subtle nutty flavor and a golden-yellow hue. There are various types of peanut oil, including:
- Refined Peanut Oil: Often used in commercial cooking, this oil is processed to remove allergens, making it safe for many with peanut allergies.
- Cold-Pressed or Unrefined Peanut Oil: This retains more nutrients and a stronger peanut flavor, ideal for salad dressings or light sautéing.
- Roasted Peanut Oil: This version has a deep, rich flavor due to roasted peanuts and works well in dishes where a pronounced nutty flavor is desired.
- Blended Peanut Oil: Sometimes, peanut oil is mixed with other oils, like soybean oil, to reduce cost or alter flavor.
