Negative Health Side Effects of Eating Bread

Bread has been a dietary staple for centuries, but its health implications have been debated recently. While bread can be part of a balanced diet for some individuals, it may have adverse health side effects for others. This article will explore some potential drawbacks of consuming bread and its impact on overall health.

Gluten Sensitivity and Celiac Disease

Gluten is a protein found in wheat, barley, rye, and their derivatives. For individuals with celiac disease, an autoimmune disorder, gluten triggers an immune response that damages the small intestine. This can lead to various digestive issues, malabsorption of nutrients, and a range of symptoms such as abdominal pain, bloating, diarrhea, and fatigue. Some may experience gluten sensitivity, even in non-celiac individuals, causing similar symptoms without the immune response.

High Glycemic Index

Many commercially available bread products, especially white bread and those made from refined flour have a high glycemic index. Foods with a high glycemic index can cause rapid spikes in blood sugar levels, leading to subsequent crashes. This can result in increased hunger, irritability, and fatigue. Consistently consuming high-glycemic foods can contribute to insulin resistance, a risk factor for type 2 diabetes and obesity.

Low Nutrient Density

Some bread varieties, mainly highly processed ones, have low nutrient density. They provide calories without significant vitamins, minerals, or other essential nutrients. Refined bread lacks the bran and germ of the wheat grain, removing essential nutrients such as fiber, B vitamins, and minerals like magnesium and zinc.

Weight Gain and Obesity

Certain types of bread can contribute to weight gain, especially when consumed in large quantities. Refined and highly processed bread can be calorie-dense and lead to overeating without providing the satiety that comes with nutrient-dense foods. Moreover, bread is often part of meals with high-calorie toppings or fillings, contributing to excess calorie intake.

Digestive Discomfort

Some individuals may experience digestive discomfort after consuming bread, even without having gluten sensitivity. This discomfort can be due to various factors, including fermentable carbohydrates in bread that can cause gas and bloating in susceptible individuals.

Preservatives and Additives

Commercially produced bread may contain preservatives and additives to extend shelf life and improve texture. These additives may not be well-tolerated by everyone and can lead to allergic reactions or other adverse effects in some individuals.


Bread, especially made from grains like wheat, may contain anti-nutrients such as phytates and lectins. These compounds can interfere with absorbing minerals like iron, zinc, and calcium.

Gut Health and Inflammation

Some research (1, 2, 3, 4) suggests that consuming certain types of bread, especially those high in refined flour and sugar, may negatively impact gut health and promote inflammation. This could contribute to various chronic diseases and conditions.

It is important to note that not all bread is equal, and some bread varieties offer health benefits. Whole-grain bread from whole wheat, oats, or other grains retains the bran and germ, providing more fiber and essential nutrients. Additionally, some individuals can tolerate gluten without any adverse effects and can include whole-grain bread as a balanced diet.

In conclusion, while bread can be a convenient and enjoyable part of the diet, it may have negative health side effects for certain individuals, especially when consumed in excess or certain forms. Moderation and mindful selection of bread types are key to making it a part of a healthy diet. If you have specific health concerns or dietary restrictions, consult with a healthcare professional or registered dietitian to determine the best approach to bread consumption in your diet.

What to do if you eat bread every day?

If you eat bread every day and are concerned about its potential adverse health effects, there are several steps you can take to make healthier choices and minimize any adverse impacts on your health:

  • Choose Whole Grain Bread: Opt for whole grain bread instead of refined white bread. Whole grain bread is richer in nutrients, fiber, and antioxidants, making it a healthier option that can help support gut health and reduce inflammation.
  • Check the Ingredients: Read the ingredient list carefully when purchasing bread. Avoid bread that contains added sugars, artificial additives, and preservatives. Choose bread with simple and natural ingredients.
  • Moderation is Key: While bread can be a part of a balanced diet, moderation is essential. Consider reducing your daily bread intake to a few servings per week instead of consuming it daily.
  • Diversify Your Diet: Incorporate a variety of nutrient-dense foods into your diet. Focus on fresh fruits, vegetables, lean proteins, whole grains, and healthy fats. This diversification will give your body essential nutrients and reduce the reliance on bread as a staple.
  • Experiment with Gluten-Free Alternatives: If you suspect that gluten might be causing digestive issues, consider trying gluten-free alternatives to bread. Gluten-free bread options are made from rice, quinoa, or almond flour.
  • Fermented Foods: Introduce fermented foods into your diet. These foods, such as yogurt, kefir, sauerkraut, and kimchi, contain beneficial probiotics supporting gut health.
  • Stay Hydrated: Drink plenty of water throughout the day. Hydration is crucial for maintaining overall health and supporting digestion.
  • Monitor Your Body’s Response: Pay attention to how your body responds to bread consumption. If you notice any adverse effects, such as digestive discomfort or inflammation, consider reducing or eliminating bread from your diet and observe if there is an improvement.

Considering your concerns about the potential adverse health side effects of eating bread every day, one approach to support better digestion and minimize discomfort is to try incorporating Goodness Digestive Enzymes into your daily routine. These natural enzymes are designed to aid in the digestion of various foods, including bread, by breaking down complex nutrients into more easily absorbable forms. By taking Goodness Digestive Enzymes before meals, you can support your digestive system in processing bread and other foods more efficiently, potentially reducing bloating and gas. Remember, moderation and a diverse diet are also crucial, so complementing these enzymes with healthier bread alternatives, such as whole grain options, is recommended. As always, consult a healthcare professional before adding supplements to your diet, especially if you have specific digestive concerns or health conditions.


  1. Impact of Gluten on Gut Health: Research has shown that gluten, a protein found in wheat and other grains, can adversely affect gut health for individuals with celiac disease and non-celiac gluten sensitivity. A study published in the journal “Gastroenterology” in 2009 investigated how gluten triggers an immune response in individuals with celiac disease, leading to gut inflammation and damage to the intestinal lining. This inflammation can result in symptoms like bloating, diarrhea, and abdominal pain.
  1. Effect of Refined Grains on Inflammation: A systematic review and meta-analysis published in the “Journal of Nutrition” in 2015 examined the relationship between refined grain consumption and markers of inflammation. The study found that a higher intake of refined grains was associated with increased inflammatory markers, such as C-reactive protein (CRP). CRP is a marker of systemic inflammation associated with an increased risk of chronic diseases like cardiovascular disease and type 2 diabetes.
  1. Role of High-Glycemic Index Foods in Inflammation: Some types of bread, particularly those made from refined flour and sugar, have a high glycemic index. A study published in the “American Journal of Clinical Nutrition” in 2002 investigated the effects of high-glycemic index foods on inflammation. The researchers found that consuming high-glycemic index foods resulted in higher levels of inflammatory markers, indicating a potential link between these foods and increased inflammation.
  1. Dietary Patterns and Gut Microbiota: The gut microbiota plays a crucial role in gut health and overall well-being. Some research has explored the impact of different dietary patterns, including bread consumption, on gut microbiota composition. A study published in the journal “Nutrients” in 2019 investigated the effects of a Western-style diet, which often includes refined grains and sugars, on gut microbiota and inflammation. The study found that this diet was associated with an unfavorable shift in gut microbiota composition and increased inflammatory markers.
