There are folk sayings such as "three nine supplements one winter, no pain in the coming year" and "winter supplements, spring and tigers", so most people think that winter is the best tonic season. Which of the following, if true, would weaken the above view most:. ['When people lack certain necessary nutrients, they should choose the corresponding supplements according to the situation.', 'Dry air in winter, timely rehydration or eating more fruits is good for human health.', 'If there is no lack of nutrition, excessive supplementation of certain nutrients may be harmful to the body.', 'Poor warming measures in the past and malnutrition in most people, the situation is now reversed.']
