- Quality sleep is essential for physical and mental well-being, but it often depends on your diet.
- Fiber promotes gut health, stimulates serotonin and melatonin production, and improves sleep.
- To increase fiber intake, choose whole foods, vegetables, legumes, and fruits with the skin on if possible.
Good sleep is essential for well-being and physical and mental health, but more and more people admit to struggling with rest. Stress, too much caffeine, and the use of computers, tablets, and smartphones before bed are among the main causes. Another often overlooked factor is diet, particularly fiber intake in daily meals.
Nutrition and sleep: an often overlooked connection
It’s well known that some foods can affect sleep, but the focus tends to be solely on substances like caffeine and excess sugars, without considering the crucial role that fiber plays, essential for gut health. Fiber helps reduce inflammation, which can significantly impact sleep quality.
Why fiber improves sleep
Fiber improves sleep quality because it helps maintain healthy gut flora, which in turn stimulates the production of serotonin, essential for the synthesis of melatonin, the hormone that regulates circadian rhythm. In addition, fiber fermentation generates short-chain fatty acids, which enhance the release of certain neurotransmitters that promote relaxation. Fiber also reduces inflammation, often associated with sleep disturbances, and stimulates the vagus nerve, improving gut-brain communication. Finally, they help control nighttime hunger by stabilizing blood sugar levels and preventing sudden awakenings.
How much fiber to eat and how to increase intake
Nutritional guidelines suggest a daily intake of about 25 grams for women and 38 grams for men. However, many people consume less than the recommended amount, averaging only 15 grams per day. If you fall into the latter category, try gradually increasing your fiber intake to avoid bloating and digestive discomfort. Here’s how:
- Choose whole foods instead of refined versions;
- Add more vegetables to meals, both raw and cooked;
- consume more legumes (lentils, chickpeas, beans), excellent sources of fiber;
- Eat more fruit with the skin (ensuring it is untreated);
- Add nuts (almonds, walnuts, hazelnuts) and seeds (flaxseed, chia) to yogurt and your salads.
Eating well to sleep better
Sleep is essential for overall well-being, and we often neglect it, seeking quick fixes like supplements or even medications, without considering how much diet can help. A proper intake of fiber can really make a difference, promoting a healthy gut, reducing inflammation, and improving the production of neurotransmitters involved in sleep. So, if you’re struggling to sleep, it might be time to review your diet and perhaps start consuming more fiber-rich foods.
