Quick Take
A social media post claims that eating peanuts can treat insomnia. We did the fact check to term this claim as mostly false.
The Claim
An Instagram post claims that “peanuts can treat insomnia.” It further suggests that eating them regularly strengthens brainwaves, frequencies, and is associated with deep sleep.
Fact Check
Do peanuts have sleep-promoting nutrients?
Yes, peanuts have some nutrients that may support sleep, like tryptophan, which helps produce serotonin and melatonin—both important for regulating sleep. They also contain magnesium, which can help in relaxation and reduce muscle tension, and niacin (vitamin B3), which supports brain function and relaxation. In our country, eating peanuts in winter is common, and they do offer some health benefits. However, just because peanuts have these nutrients doesn’t mean they can significantly improve sleep or cure insomnia. Many other foods, like dairy, turkey, and bananas, also contain tryptophan and magnesium, but they aren’t considered direct treatments for sleep disorders.
We spoke with Dr Swati Dave, PhD in Food and Nutrition, to gain her expert perspective on the sleep-promoting nutrients in peanuts. She says, “Peanuts are a good source of tryptophan, an amino acid that helps the body produce serotonin and melatonin, hormones that play a key role in regulating sleep. Along with healthy fats, protein, and magnesium, which support muscle relaxation, peanuts can contribute to improved sleep quality when consumed in moderation as part of a balanced diet.”
Can peanuts cure insomnia?
No, insomnia is a complex sleep disorder caused by various factors like stress, mental health issues, lifestyle habits, and medical conditions. Eating peanuts alone will not fix underlying sleep problems. Research on insomnia treatment mainly focuses on cognitive behavioural therapy (CBT), lifestyle changes, and, in some cases, medication. While peanuts have nutrients that may support relaxation, they are not a cure. If someone struggles with persistent insomnia, it’s important to seek advice from a healthcare professional.
Similarly, some social media posts also claim that cardamom can cure insomnia. However, this is incorrect.
Do peanuts strengthen brainwaves and frequencies?
Not really. The claim that peanuts can “strengthen brainwaves and frequencies” lacks scientific basis. Brainwaves are patterns of electrical activity in the brain, and their regulation is influenced by factors like sleep cycles, mental activity, and external stimuli. While peanuts provide healthy fats and antioxidants that support overall brain health, they do not have a specific effect on brainwave activity or frequency modulation.
Moreover, scientific studies on brain function and nutrition focus more on a balanced diet, including omega-3 fatty acids, which are found in fish and flaxseeds, rather than peanuts alone.
Is there a risk of eating peanuts before bed?
Yes, for some people. Peanuts are high in calories and fats, which take time to digest. Eating too many before bed may cause bloating, acid reflux, or discomfort. They also contain tyrosine, which can be mildly stimulating for some. People with peanut allergies should avoid them, as even a small amount can trigger severe reactions. Poorly stored peanuts may develop aflatoxin, a toxin that can harm the liver, but proper storage helps prevent this. Peanuts also have phytic acid, which slightly reduces iron and zinc absorption, though this isn’t an issue for those with a balanced diet.
What are proven ways to improve sleep quality?
Improving sleep requires a combination of healthy habits, such as:
Maintaining a consistent sleep schedule
-
Reducing exposure to screens before bedtime
-
Creating a comfortable sleeping environment
-
Avoiding caffeine, nicotine, and heavy meals late in the evening
-
Engaging in relaxation techniques, such as meditation or reading
-
If insomnia persists, medical evaluation may be needed to rule out underlying conditions like anxiety, depression, or sleep disorders.
We checked with Dr Roma Kumar, Senior Consultant Psychologist at Sir Ganga Ram Hospital & Max Hospital, New Delhi, for her opinion on proven ways to improve sleep. She explains, “Improving sleep quality starts with maintaining a consistent sleep schedule, going to bed and waking up at the same time every day, even on weekends. Creating a calming bedtime routine, such as reducing screen time an hour before bed, helps signal your brain that it’s time to wind down. Relaxation practices like deep breathing, meditation, or light stretching can also help lower stress levels. Additionally, creating a comfortable sleep environment by keeping the room cool, dark, and quiet, while limiting caffeine or heavy meals before bedtime, can further enhance your sleep quality.”
THIP Media Take
The claim that peanuts can treat insomnia is mostly false. While peanuts contain nutrients that support relaxation, there is no scientific evidence that eating peanuts can cure insomnia or significantly alter brain activity for better sleep. Managing insomnia requires a holistic approach, including good sleep hygiene, stress management, and, if necessary, medical advice. Relying on peanuts alone is not an effective solution for treating sleep disorders.
