Hello, I'm an expert in nutrition and health, and I'm here to provide you with accurate information regarding vitamins and their stability under various conditions.
When it comes to vitamins and their susceptibility to heat, it's important to understand that different vitamins have different properties and stability levels. Some vitamins are indeed sensitive to heat and can be destroyed or significantly reduced in their potency when exposed to high temperatures, while others are more heat-stable.
Vitamin C, as you mentioned, is a water-soluble vitamin that is found in a variety of fruits and vegetables. It is known for its antioxidant properties and its role in the immune system, among other functions. Unfortunately, Vitamin C is one of the vitamins that is particularly sensitive to heat. When food containing Vitamin C is cooked, especially at high temperatures, the vitamin can be destroyed or its bioavailability can be significantly reduced. This is due to the fact that Vitamin C is easily oxidized and can be leached out into the cooking water, leading to its loss.
However, not all vitamins are as heat-sensitive as Vitamin C. One of the vitamins that is known for its heat stability is Vitamin D. Vitamin D is a fat-soluble vitamin, which means it is stored in the body's fatty tissues and liver rather than being excreted quickly like water-soluble vitamins. It is synthesized in the skin in response to sunlight and can also be obtained from certain foods and supplements. Importantly, Vitamin D is not easily destroyed by heat, making it one of the more heat-stable vitamins. This property is beneficial because it allows for the fortification of foods with Vitamin D without the concern of significant loss due to cooking or processing.
Another heat-stable vitamin is Vitamin E. Similar to Vitamin D, Vitamin E is fat-soluble and is known for its antioxidant properties. It is found in various foods, including nuts, seeds, and vegetable oils. Vitamin E is also quite stable when exposed to heat, which means that it can be added to foods and remain active even after cooking or baking.
It's also worth noting that Vitamin K, another fat-soluble vitamin, is relatively stable to heat. Vitamin K is essential for blood clotting and bone metabolism, and it is found in green leafy vegetables, certain animal products, and some fermented foods. While some loss of Vitamin K can occur during cooking, it is generally more heat-resistant than water-soluble vitamins like Vitamin C.
In summary, while many vitamins can be affected by heat, there are a few, particularly the fat-soluble ones like Vitamins D, E, and K, that are more resistant to heat and maintain their structure and function even when exposed to high temperatures. This is an important consideration for food processing and cooking, as it helps to ensure that we can still obtain these essential nutrients from our diet.

Vitamin C, also known as ascorbic acid, is a water-soluble vitamin found in fruits and vegetables, including oranges, strawberries, broccoli, tomatoes and green peppers. Vitamin C is easily destroyed by excessive heat and water, as well as exposure to air.
