Adding spices to food or adding sauce to diets is likely to improve the body's absorption of vitamins and minerals, and scientists believe that this process can increase the amount of nutrients that the human body uses from its food.

Black pepper has been a precious spice for thousands of years, with its ability to flavor the most tasteless foods, and India was the first to cultivate this plant more than 3,500 years ago, and is the original home of the plant, which later became one of the most valuable commodities in the ancient world.
Most people nowadays use it to season food without paying much attention to its nutritional value.
However, adding black pepper to a meal goes beyond improving the flavor of food, as it contributes to enhancing the amount of nutrients that the human body absorbs from food.
Peppercorns contain a chemical compound that facilitates the absorption of vitamins and other nutrients into the bloodstream, and scientific studies have shown that the tiny drops of fat found in milk and olive oil enhance the availability of nutrients to the body.
Scientists are now seeking to harness these properties by developing new types of foods that contain supporting elements, as well as helping people with poor absorption of the nutrients necessary to maintain their health.
One of the problems associated with foods with higher nutritional value is the body's ability to absorb and extract vitamins and minerals as they pass through the digestive tract.
For example, sweet corn kernels are rich in beneficial elements, as they contain a high percentage of fiber, protein, and vitamins, in addition to microelements such as potassium, although some may wonder how much of these nutrients the body has absorbed after eating them, due to the difficulty of breaking down the outer waxy shell of corn, especially if it is not chewed well.
David Julian McClements, a professor of food science at the University of Massachusetts in the US, said: "When sweet corn is eaten without chewing enough, it crosses the entire digestive tract and then goes down the toilet, and the nutrients inside are still retained."
However, chewing sweet corn well allows the nutrient-rich pulp to be released into the kernel, which helps the digestive system break it down and utilize it.
The sauce you add to a salad may not only add flavor, but may also increase nutritional value.
