The Experts Agree: What You Eat Can Directly Impact Stress and Anxiety

Eating habits and stress levels work hand in hand. Research has shown that foods can directly impact our stress and anxiety levels. Experts agree that dietary changes can play a significant role in managing stress and anxiety.

Studies point to connections between certain types of food and mental illnesses and mood disorders, including anxiety and depression. Certain foods can act as natural tranquilizers, calming our minds and allowing us to think clearly. On the other hand, some foods can increase stress and anxiety.

Research suggests high-sugar foods like candy and cake can cause blood sugar spikes, leading to anxiety and irritability. Caffeine can also cause anxiety, so limiting caffeine intake is imperative to reduce stress levels. Staying hydrated also helps manage stress and anxiety.

Our food choices affect our brains because our gastrointestinal system or gut is closely connected to the brain. Most of us don’t pay close attention to our eating habits, so nutritionists recommend keeping a food journal. If you find it challenging to control your eating habits, whether you’re eating too much or too small, your health may be in jeopardy. The cycle is vicious, but it can be overcome.

Stress and Anxiety

It is no secret that stress, anxiety, and food are closely linked. When stressed or anxious, it can be hard to make healthy food choices, and often we find ourselves reaching for unhealthy options. Stress and anxiety can also trigger overeating or binge eating, leading to feeling out of control and guilt.

The American Dietetic Association claims that people frequently eat too much or too little when anxious or under stress. An excessive intake of calories will lead to fatigue and weight gain. It’s difficult to quit this habit of eating too little because of the weariness it causes. In any scenario, eating poorly while stressed out or depressed just makes things worse.

Food and Mood: The science behind it

Food and mood are complex and deeply intertwined. Eating certain foods can affect our mood and state of mind, while certain emotions can influence us to reach for specific types of food. Food and mood have been fascinating topics studied for decades.

Dr. Alan Hinman conducted one of the most significant research on food and mood in the 1970s. He discovered that rats given sugar were more likely to exhibit depression symptoms. This study showed a possible link between sugar and mood. According to a 2015 review, highly processed meals may increase depression risk.

Other studies have found that people who eat diets high in omega-3 fatty acids have lower levels of depression and anxiety than those who don’t consume enough omega-3 fatty acids. Omega-3 fatty acids are found in fish, nuts, flaxseed oil, and other foods. A 2021 study published in Clinical Nutrition discovered that a diet high in fruit and vegetables also reduces stress levels.

It is also believed that the gut microbiome plays a role in our mental health. Studies have found that people with a healthy gut microbiome have less anxiety and better cognitive function. Bacteria and other organisms in our intestines make up the gut microbiome. A diet high in fiber, probiotics, and fermented foods can support balanced gut flora.

In addition to diet, what we eat also affects our mood. Eating small meals throughout the day can help blood sugar levels stay stable and improve mood. Processed foods, on the other hand, spike blood sugar levels and lead to energy crashes and mood swings.

Eating well and understanding the science behind food and emotions can improve mental health. Eating a healthy, balanced diet, managing stress, and getting enough rest can all improve our mental well-being and keep us productive.

How Diet can affect Stress Levels for Better or Worse?

“Diet plays an essential role in how we feel,” an observation from Ph.D. psychologist ‘Alex MacLellan from Practical Anxiety Solutions notifies the audience. Eating well can help you manage stress and feel more in control of your emotions, while poor diet choices can have the reverse effect.

Intake of high sugar and refined carbohydrate can spike blood sugar levels, resulting in energy slumps and increased stress hormone production. Eating a diet high in processed foods and saturated fats can also cause sluggishness, which increases stress levels.

On the other hand, a balanced diet full of nutrient-rich foods can help you cope with stress. Eating foods that contain complex carbohydrates, high-quality proteins, and healthy fats can help maintain steady blood sugar levels and keep energy levels up throughout the day. Eating these foods can also make you feel better and more alert – and less prone to stress.

Healthy sources of complex carbohydrates include whole grains, legumes, and vegetables. High-quality proteins can be found in lean meats, fish, eggs, dairy, and plant-based proteins. Healthy fats are found in nuts, seeds, avocados, and olive oil.

If you know that drinking alcohol makes you feel irritable the next day, it’s enough to make carefully calculated decisions about drinking alcoholic beverages.

In addition to eating a healthy, balanced diet, get enough rest and stay hydrated. Even mild dehydration can cause fatigue, which contributes to stress.

Mindful Eating

Mindful eating is an approach to maintaining an in-the-moment awareness of the food and drinks you put into your body. It is about being aware of your body’s physical cues and emotional needs and honoring them. Mindful eating encourages us to slow down and pay attention to our food and eating experience. This is better than eating distracted, rushed, or mindlessly.

Mindful eating involves observing how food makes you feel and signals your body about taste, satisfaction, and fullness. It also includes what to eat, how much to have, and when to do so. This will help us make better food choices that nourish our bodies.

Mindful eating can help us avoid unhealthy habits such as overeating or eating out of boredom. It can also help us recognize when we are full and satisfied, allowing us to make the most of our meals and enjoy them more.

Nuts and seeds are also healthy fat sources. Other foods include avocados, olives, and whole eggs supplemented with omega-3 fatty acids.

6. Fermented food

Probiotics, living microorganisms beneficial for your digestive system, are abundant in fermented food. Examples include kombucha,sauerkraut, kimchi, miso, and tempeh. If you have high blood pressure, consume these foods in moderation or avoid them because they are also high in salt.

3. Eat protein-rich foods. Protein-rich foods can keep you full and satisfied. Added lean protein sources to your meals and snacks can reduce overeating temptation.

4. Limit your intake of processed foods. Steer clear of processed snack foods, such as potato chips, which impair concentration. Pass up sugar-filled snacks, such as candy and soft drinks, which cause energy fluctuations.

Follow these tips to reduce your stress and anxiety about food during the holidays. Eating should be enjoyable. It is worthwhile to take a break and enjoy food. Finally, be mindful of your mental health and get help if needed.
