Why is the center of the lettuce head considered the healthiest part?
The center of the lettuce head, also known as the core or heart, is considered the healthiest part of the lettuce due to its higher concentration of nutrients and antioxidants. This is because the core of the lettuce head is where the plant’s energy is focused, and as a result, it tends to have higher levels of vitamins, minerals, and other beneficial compounds.

Additionally, some parts of the lettuce plant, like the roots, may contain higher levels of certain compounds that can be toxic in large quantities. As with any food, it’s essential to consume the stems and roots of the lettuce plant in moderation and as part of a balanced diet.
