Avocado is a healthy food that contains magnesium and the amino acid tryptophan, as you mentioned. Magnesium can actually help reduce stress and relax muscles, which can help improve the quality of your sleep. Tryptophan is a precursor to melatonin, a hormone that regulates sleep and wakefulness.

However, it is important to remember that nutrition is only one factor that affects stress and sleep. Other factors such as lifestyle, physical activity, sleep patterns and psychological state also play an important role in combating stress and insomnia.

Eating an avocado can be part of a healthy diet, but it alone is not a cure-all for sleep and stress problems. If you have chronic problems with insomnia or stress, it is important to consult with your doctor to determine the best treatment plan and appropriate lifestyle changes.
