As a nutrition and food science expert, I've spent years studying the effects of various cooking methods on the nutritional content of food, including the retention of minerals. Minerals are inorganic elements that are vital for various bodily functions, and they are naturally present in many foods. The question of whether minerals can be destroyed by cooking is a complex one, as it depends on several factors including the type of mineral, the cooking method, and the food matrix.
Firstly, it's important to understand that minerals themselves are not destroyed by heat. Heat can alter the physical state of food and its components, but it does not chemically break down minerals. However, cooking can affect the bioavailability of minerals, which refers to the proportion of the element that can be absorbed and utilized by the body.
When we cook food, especially in water or other liquid mediums, minerals can leach out into the cooking liquid. This is particularly true for water-soluble minerals such as sodium, potassium, and calcium. Boiling vegetables, for example, can result in a loss of minerals as they dissolve into the water. The extent of this loss depends on the cooking time, the mineral content of the food, and the type of mineral.
Steaming is often considered a healthier cooking method in terms of nutrient retention, including minerals. This is because steaming does not require the addition of water, thus minimizing the leaching of minerals. However, even with steaming, some minerals can still be lost, particularly if the cooking time is too long.
Another factor to consider is the food matrix. The structure of the food can affect how minerals are retained or lost during cooking. For instance, the cell walls of vegetables can protect minerals from leaching out. However, when these cell walls are broken down by cooking, minerals may become more susceptible to loss.
Additionally, the presence of certain compounds in food can affect mineral bioavailability. For example, oxalic acid found in spinach can bind to calcium, reducing its absorption. Cooking can alter these compounds, potentially increasing or decreasing the bioavailability of minerals.
It's also worth noting that some cooking methods can actually enhance the bioavailability of certain minerals. For instance, cooking tomatoes can increase the availability of lycopene, a powerful antioxidant.
In conclusion, while cooking does not destroy minerals, it can influence their bioavailability through leaching, changes in the food matrix, and interactions with other food components. To maximize mineral retention, it's important to choose cooking methods that minimize the loss of nutrients, such as steaming or using minimal water. Additionally, consuming a varied diet can help ensure that you're getting a broad range of minerals from different sources.

Here, we shall compare the mineral content between raw and cooked foods. Though minerals are not lost due to heat, but are usually leached if cooked in boiling water, steaming is probably the best cooking method with respect to mineral loss. Otherwise, heating doesn't destroy minerals.
