"People who eat potatoes will never be able to perform their abilities in whatever job they choose to have"

This quote by Richard Cobden suggests that people who eat potatoes will not be able to reach their complete capacity in whatever task they select to have. This might be analyzed as a warning versus relying too greatly on potatoes as a dietary staple, as it could cause an absence of energy and focus that is necessary for success in any task. It could also be translated as a criticism of the potato-heavy diet plans of the working classes in Cobden's time, as he believed that such diet plans were harmful to their health and efficiency. Eventually, this quote serves as a tip that a balanced diet plan is essential for attaining one's objectives, which potatoes should not be the only source of sustenance.
