Final answer:
The statement is true as diets high in protein and fiber can indeed impair zinc absorption due to the presence of substances like phytates, which bind to zinc and other minerals, reducing their bioavailability.
Step-by-step explanation:
The statement that diets high in protein and fiber can impair zinc absorption is True. High amounts of protein, especially from vegetarian sources that may contain nonessential amino acids and lack one or more essential amino acids, can influence the absorption of minerals like zinc.
Additionally, fiber-rich diets can affect the bioavailability of minerals. Substances such as phytates, which are found in high-fiber foods, can bind to zinc and other minerals, thereby reducing their absorption. While diets high in fiber and certain types of protein can be beneficial for weight management and may reduce the risk of chronic diseases such as heart disease and Type 2 diabetes, they may also lead to a higher risk of certain nutrient deficiencies.
It's essential to maintain a balance and potentially supplement certain nutrients, like zinc, to avoid deficiencies while adhering to guidelines regarding fat and nutrient consumption for overall health.
