Because a healthy diet is about balance, too much wheat bread is not a good thing. To get the most from your wheat bread, eat the recommended portions and choose whole-grain products made from the entire grain kernel over products that say "enriched," which generally means refined. The U.S. Department of Agriculture recommends adult women consume around 6 oz. daily, while men need slightly more -- approximately 8 oz., although men over 30 need only 7 oz. daily.
It's uncertain whether a high intake of dietary fiber, which exists in wheat bread, prevents or promotes colorectal cancer, says MayoClinic.com. Evidence is mixed, as some studies show benefit, and others suggest an increased risk. To be safe, consume only the recommended portions of wheat bread and dietary fiber and follow a regular colon cancer screening regimen.
Eating too much wheat bread can lead to wheat gain if you consume more calories than your body can use. Although your individual calorie needs vary, based on you age, sex, current weight, health status and activity level, most people should consume fewer than 2,000 calories daily to maintain their weight. Additionally, incorporating a regular exercise regimen of at least 30 minutes of aerobic exercise on most days will help you burn any additional calories you consume.
If consuming too much wheat bread keeps you from eating other foods your body needs, you might develop a nutritional deficiency. Physical signs of nutritional deficiencies include, dry hair, brittle nails, excessive ear wax, tooth decay, cold hands and slow wound healing. The symptoms vary based on the nutrients you're lacking. In general, if you feel fatigued or ill often, your body is likely sending you a message. Consult your doctor for advice.
A person with a food allergy to wheat can experience several bothersome effects from consuming too much wheat bread. Stomach cramps, bloating and gas are among them. Additionally, people who have a gluten intolerance, such as those with celiac disease, might experience chronic diarrhea or constipation, sudden weight loss or weight gain and anemia. Because the disease can appear at any time, and can be triggered by a viral infection, a surgical procedure, pregnancy, childbirth or stress, you should talk to your doctor if you experience unusual symptoms after consuming wheat bread.
