How do fruits and vegetables with high protein content affect human health?
Nitrate content is one of the indicators of food safety. Nitrate originates from fertilizer. If too much fertilizer is applied, the nitrate content in vegetables will increase significantly. If excessive nitrate is retained, continuous consumption can affect metabolism and damage the liver and kidneys. However, in most cases, it is difficult to determine the nitrate content in fruits and vegetables. Therefore, housewives can refer to the following tips.
1. Tomatoes:
– Smooth and shiny skin, thin skin, no denting or bruising. If the fruit is still green, it will not ripen well.
– Remember: Choose ripe and fragrant tomatoes; thick skin may contain excessive nitrate due to excessive fertilizer application.
2. Cabbage:
– Exterior: Thin leaves, no dark or discolored areas.
– Keep in mind: Choose cabbage that does not change shape when squeezed. If the leaves are tightly rolled and thick, it is likely that there is too much fertilizer.
3. Cauliflower:
– Exterior: Cauliflower should be white or yellow; the surface should not have any mold or dirt spots.
– Need to: Cauliflower should feel firm when held, indicating its safety.
4. Cucumbers:
– Exterior: Bright green color, thin skin, with a white film.
– Remember: Choose small, firm cucumbers with no bulging or wrinkled skin. The stem of the cucumber should not have yellow or gray sap, indicating it is not fresh.
5. Potatoes:
– Exterior: Thin, smooth skin with few pores, bruising, and green color.
– Remember: Choose potatoes of medium size.
