Sugary Foods: A Recipe For Sleepless Nights?

Eating sugary foods can lead to a disturbed night's sleep. A diet high in sugar can cause you to sleep less deeply and feel more restless at night. This is because sugar causes an increase in blood sugar levels, which can then lead to a blood sugar crash, resulting in fatigue. This fatigue can cause you to eat later in the day, which can further disrupt your sleep. Additionally, sugar can be stimulating and give you a boost of energy, which is the opposite of what you want at night.

How blood sugar spikes and crashes affect sleep

Eating foods high in added sugar can negatively affect your health and quality of life. It can also affect your sleep quality.

When you eat foods high in sugar, your blood sugar spikes. This is because your body breaks down the carbohydrates in your food into glucose, which is a simple sugar. As the amount of sugar in your blood increases, your cells absorb it and either convert it into energy or store it for later use.

If you eat a lot of sugary foods, your blood sugar will spike more than if you eat complex carbohydrates like vegetables and whole grains. This is because simple carbohydrates are broken down quickly, leading to a large amount of glucose entering your bloodstream all at once. This results in a blood sugar spike, followed by a crash when your blood sugar levels fall.

These extreme spikes and crashes in blood sugar can cause a slump in energy, making you feel sleepy. They can also cause difficulty concentrating and other symptoms that can interfere with your daily activities.

In addition to the direct impact on your energy levels, blood sugar spikes and crashes can also affect your sleep quality. If you eat a sugary snack before bed, for example, your blood sugar will spike and then crash while you're sleeping. This can cause you to wake up in the night or sleep restlessly.

Over time, frequent blood sugar spikes and crashes can also contribute to chronic inflammation, which is a long-term response by your immune system. This, in turn, can lead to further complications and symptoms, including fatigue.

To avoid blood sugar spikes and crashes, it's important to limit your consumption of foods high in simple carbohydrates, such as packaged cookies, crackers, snacks, baked goods, pastries, and sugary drinks. Instead, focus on eating high-quality complex carbohydrates like whole grains, legumes, vegetables, and fruits.

Additionally, improving your sleep quality can help to reduce excessive daytime sleepiness. This may include maintaining a consistent sleep schedule, limiting screen time before bed, and avoiding caffeine late in the day.

The link between high sugar intake and sleep disturbances

High sugar intake has been linked to poor sleep quality and disturbances in sleep. This is due to the effect of sugar on blood sugar levels, which can cause extreme spikes and crashes, leading to a slump in energy levels and sleepiness.

When you consume sugary foods, your body breaks down the simple carbohydrates into glucose. As the amount of glucose in your blood increases, your cells absorb it and either convert it into energy or store it for later use. This process can lead to a rapid increase in blood sugar levels, known as a spike, followed by a drastic fall or "crash". These extreme fluctuations in blood sugar can result in a decrease in energy levels, causing sleepiness and difficulty concentrating.

Several studies have found a significant association between high sugar intake and poor sleep quality. One study involving university students found that participants with higher added sugar intake were more likely to have poor sleep quality. Another study of over 42,000 people with type 1 or type 2 diabetes reported that about half of the participants experienced feelings of exhaustion. These findings suggest a potential link between high sugar consumption and sleep disturbances.

Additionally, high sugar intake can contribute to other health issues such as obesity, high blood pressure, insulin resistance, and inflammation, which can further impact sleep quality. Consuming sugary drinks, packaged snacks, and baked goods has been associated with spikes and crashes in blood sugar, leading to tiredness after meals. On the other hand, complex carbohydrates like vegetables and whole grains are broken down more slowly, resulting in a gradual rise and fall in blood sugar levels, which may help mitigate sleep disturbances.

It is important to note that everyone responds differently to foods, and individual factors such as gut microbiome composition can influence how the body manages energy levels and blood sugar responses. While high sugar intake may be a contributing factor to sleep disturbances, other lifestyle factors, such as physical activity levels, quality of life, and overall diet, also play a role in sleep quality.

Why sugar can be addictive

Sugar can be addictive due to its effects on the brain's limbic system, which is associated with emotional control. When consumed, sugar releases opioids and dopamine, a neurotransmitter that is part of the "reward circuit" associated with addictive behaviour. Dopamine creates a reinforcing cycle, leading to cravings and the repeated behaviour that releases it.

A 2008 study found that rats could become dependent on sugar, and that this dependency could be related to several aspects of addiction: cravings, binging, and withdrawal. Rats with intermittent access to sugar showed behavioural and neurochemical changes that resembled the effects of a substance of abuse.

The symptoms of sugar addiction include intense cravings, difficulty controlling consumption, persistent desire for sweet tastes, withdrawal-like symptoms when attempting to quit, continued consumption despite negative consequences, preoccupation with thoughts of sugary foods, difficulty maintaining a balanced and healthy diet, and increased tolerance to sugar.

Sugar addiction is not recognised as a formal diagnosis in medical or psychological literature, but many people experience strong cravings and difficulties controlling their sugar intake, which can impact their overall health and well-being.

How to break the sugar-sleep vicious cycle

Sugar is energy, and when you eat it, your body will store some of it for later use. However, too much sugar can lead to a vicious cycle that negatively affects your health and quality of life. Here are some ways to break this cycle:

• Reduce or eliminate excess sugar: Start by cutting out sugary drinks like soda and fruit juice, as well as refined carbohydrates like pasta, white rice, and pastries. Try to limit your intake of honey, maple syrup, and other sugar condiments as well.
• Replace with plant-based sources: Opt for whole fruits and non-starchy vegetables, whole grains, and beans. These foods release sugar more slowly into your bloodstream, providing a steadier source of energy.
• Avoid dried fruits: These tend to have a higher concentration of sugar. Stick to berries, oranges, and apples, and avoid mangoes and pineapples.
• Experiment with meal timing: Try increasing the time between dinner and breakfast with "time-restricted eating." Start with a 10-hour window, such as dinner by 8 pm and breakfast no earlier than 6 am, and gradually increase to 12 hours if possible.
• Avoid snacking: If you must, limit yourself to one planned snack per day.
• Eat only when hungry: Avoid eating when you're anxious or bored.
• Supplement with exogenous ketones: These can help with the "hangry" feeling as your body adjusts.
• Exercise regularly: Physical activity can help manage blood sugar levels and improve sleep quality. However, avoid strenuous activity close to bedtime.
• Manage stress: Practice meditation, deep breathing, or yoga to reduce stress levels, which can impact both sleep and blood sugar regulation.
• Monitor your blood sugar: Keep track of your blood sugar levels to identify patterns and adjust your diet and lifestyle accordingly.
• Talk to a healthcare professional: Discuss your sleep issues and blood sugar management with a doctor, especially if you suspect you may have diabetes or another underlying condition.

Foods to eat to control blood sugar spikes

Consuming foods high in added sugar can negatively affect your health and quality of life. It can lead to sleep issues and increase your risk of heart disease, diabetes, and cancer. A diet high in added sugar can also cause insulin resistance, which is when your cells do not respond effectively to insulin, leading to a build-up of glucose in the bloodstream. This can result in various health problems, including heart disease, kidney damage, nerve damage, and vision loss.

To control blood sugar spikes, it is essential to make dietary changes and adopt a healthier lifestyle. Here are some foods that can help:

• Broccoli and broccoli sprouts: They contain sulforaphane, a compound with blood sugar-reducing properties. Test-tube, animal, and human studies have shown that sulforaphane-rich broccoli extract improves insulin sensitivity and reduces blood sugar levels.
• Seafood: Seafood, including fish and shellfish, is a good source of protein, healthy fats, vitamins, minerals, and antioxidants. Protein helps slow digestion, prevents post-meal blood sugar spikes, and increases satiety.
• Pumpkin and pumpkin seeds: Pumpkin is a traditional diabetes remedy in many countries and is high in polysaccharides, which have been studied for their blood sugar-regulating potential. Pumpkin seeds are packed with healthy fats and protein, making them excellent for blood sugar management.
• Nuts and nut butter: Research suggests that consuming nuts may help regulate blood sugar levels. For example, a small study found that consuming peanuts and almonds throughout the day as part of a low-carb diet reduced fasting and post-meal blood sugar levels in people with type 2 diabetes.
• Okra: Okra is a fruit commonly used as a vegetable. It contains polysaccharides and flavonoid antioxidants, which help reduce blood sugar by inhibiting certain enzymes.
• Flaxseed: Flaxseed is rich in fiber and healthy fats and may help lower blood sugar levels. An 8-week study found that consuming yogurt with flaxseed significantly reduced long-term blood sugar regulation markers compared to plain yogurt.
• Beans and lentils: These are rich in magnesium, fiber, and protein, which may help lower blood sugar. They are particularly high in soluble fiber and resistant starch, which slow digestion and improve blood sugar response after meals.
• Kimchi and sauerkraut: These fermented foods contain probiotics, minerals, and antioxidants, which are associated with improved blood sugar and insulin sensitivity. A 2021 review concluded that probiotic foods had a notable effect on blood sugar regulation in people with type 2 diabetes.
• Chia seeds: Chia seeds are linked to reductions in blood sugar levels and improvements in insulin sensitivity. A 2020 review of animal studies suggested that chia seeds might improve insulin sensitivity and reduce the risk of diabetes.
• Kale: Kale contains fiber and flavonoid antioxidants, which may help decrease blood sugar levels. A study found that consuming kale-containing foods with a high-carb meal significantly decreased post-meal blood sugar levels.
• Berries: Berries are rich in fiber, vitamins, minerals, and antioxidants, making them an excellent choice for blood sugar management. Studies have shown that consuming berries can improve insulin sensitivity and enhance glucose clearance from the blood.
• Avocados: Avocados are rich in healthy fats, fiber, vitamins, and minerals. Adding avocados to meals may improve blood sugar management and protect against metabolic syndrome by promoting fat loss.
• Oats and oat bran: Oats and oat bran are high in soluble fiber, which has been shown to reduce blood sugar levels. An analysis of 16 studies found that oat intake significantly reduced long-term blood sugar regulation markers and fasting blood sugar levels.
• Citrus fruits: While citrus fruits like oranges and grapefruit contain natural sugar, they are considered low to medium on the glycemic index. They are good sources of fiber and plant compounds, such as naringenin, which has powerful anti-diabetic properties.
• Kefir and yogurt: These fermented dairy products may help regulate blood sugar. An 8-week study found that drinking kefir, a probiotic-rich yogurt drink, significantly reduced fasting blood sugar and improved long-term blood sugar regulation in people with type 2 diabetes.
• Eggs: Eggs are a good source of protein, healthy fats, vitamins, minerals, and antioxidants. Studies have linked egg consumption to better blood sugar regulation. For example, a study found that eating one large egg per day led to a significant reduction in fasting blood sugar levels and improvements in insulin sensitivity.
• Apples: Apples contain soluble fiber and plant compounds, such as quercetin, chlorogenic acid, and gallic acid, which may help reduce blood sugar and protect against diabetes. A study found that eating apples before a rice meal significantly reduced post-meal blood sugar levels.
