As the sunshine slowly returns and summer days draw near, many of us will be turning to summer salads and healthy eating to get 'beach body ready' - and for those still looking to shed some Christmas pounds, lettuce is a popular choice.

The only problem is that it goes off so fast, sparking a race between your diet and your fridge to get it eaten before it goes brown and wilts. That's why have issued a tip to keep lettuce fresh, crisp and green for longer without going off - using tin foil.

Kitchen foil, as it's also known, can help keep lettuce fresh for up to 30 days, because it regulates moisture and stops the air rotting the .

According to Wheeldon Brothers, wrapping a fresh lettuce in tin foil before putting it in the fridge can by up to 30 days.

They said: "Wrapping freshly bought lettuce in tin foil before placing it in the fridge can extend its shelf life significantly - up to 30 days.

"This clever trick helps to regulate moisture and airflow, preventing those pesky brown spots that often plague salad greens."

Other salad favourites can also benefit from a storage hack. Cucumbers should be stored in a plastic bag in a cool part of the kitchen, not the fridge, they said, while spring onions should be put in a glass with some water.

"When it comes to cucumbers, steer clear of the fridge. Instead, store them in a plastic bag with holes for ventilation, and place them in a cool spot in your kitchen to maintain their crispness."

Another way to keep lettuce fresh is by storing it in a plastic container with paper towels.

This stops air getting to it, while the paper towel absorbs and traps moisture, which also stops it from going off.

All Recipes.com adds: "Even though the lettuce did last long past the best-by date, the paper towel doesn't necessarily stop it from wilting or getting slimy. The main difference, however, is that the slimy lettuce isn't coming into contact with a lot of pieces around it because the paper towel is trapping the wetness. Whereas, when you store lettuce right-side up, the slimy pieces on the bottom touch every piece around it and contaminate them in the process."
