There is no direct evidence to suggest that baking soda added to food makes it more filling compared to when it is not added. Baking soda (sodium bicarbonate) is primarily used in cooking and baking as a leavening agent, meaning it helps baked goods rise by producing carbon dioxide gas when combined with acidic ingredients like buttermilk, yogurt, or vinegar. It does not have any inherent properties that would contribute to increased satiety or feelings of fullness.
The feeling of fullness after eating is influenced by several factors, including the volume of food consumed, the presence of nutrients like protein and fiber, and individual metabolism and hormonal responses. Foods that are high in fiber, protein, and healthy fats are generally more satiating and can help you feel full for a longer time.
While baking soda doesn't directly impact satiety, it can indirectly affect the overall eating experience. For example, when used in baked goods, it can help create a light and airy texture, making the food more enjoyable to eat. This might lead to a perception of satisfaction, but it's not directly related to the satiety signaling in the body.
In summary, while baking soda can be a useful ingredient in certain recipes, it doesn't have a significant role in making food more filling. The sense of fullness after eating depends on a complex interplay of various factors related to the food's composition and the body's physiological responses.
