Wheat Nutrition Facts, Benefits And Its Side Effect

Wheat is one of the most commonly consumed grains worldwide and an essential part of many diets. Rich in fibre, protein, vitamins, and minerals, wheat contributes to digestive health, sustained energy, and overall nutritional balance. It is a good source of complex carbohydrates that provide long-lasting energy. However, like any food, it is important to consume wheat in moderation as part of a balanced diet. While wheat offers several health benefits, such as supporting digestive health and aiding in weight management, it is crucial to remember it is unsuitable for individuals with celiac disease, gluten intolerance, or wheat allergies [5].

In this article, we will explore the nutritional profile of wheat, its health benefits, and any potential side effects to consider for a safe and informed consumption.

Wheat Nutrition Facts (Per 100g)

A 3.5-ounce (100g) serving of unenriched whole wheat flour provides the following approximate nutritional values:

1. Carbohydrates

Wheat, like all cereal grains, is mostly constituted of carbohydrates. Starch, the primary carbohydrate in plants, accounts for more than 90% of wheat’s total carbohydrate content.

2. Fibre

Compared to processed wheat, whole wheat is rich in fibre, with a fibre level of between 12% and 15% of its dry weight. This crucial fibre is concentrated in the bran, which is removed from refined flour during the milling process.

3. Protein

Protein content in wheat ranges from 7–22% of its dry weight. Gluten proteins account for roughly 80% of the total, giving wheat dough its distinctive elasticity and stickiness that is essential for breadmaking.

4. Vitamins and Minerals

Whole-grain wheat is a significant source of several essential vitamins and minerals, including selenium, manganese, phosphorus, copper, and folate. Refined wheat is deficient in many of these nutrients, as they are concentrated in the bran and germ, which are removed during milling.

5. Other Plant Compounds

The aleurone layer of wheat bran is especially rich in antioxidants and other beneficial compounds, including:

• Ferulic acid
• Phytic acid (Phytate)
• Alkylresorcinols
• Lignans
• Lutein

Top 6 Health Benefits of Wheat

Whole wheat benefits the body primarily through its high fibre content and rich supply of micronutrients and phytochemicals.

1. Improves Body Metabolism & Supports Weight Management:

The high fibre content of whole wheat is directly linked to improved digestion and metabolism [4]. Furthermore, its high fibre content promotes satiety, which may help reduce overall calorie intake. Regular consumption of whole-grain wheat has been linked to gradual and sustained weight loss in individuals with obesity, likely through mechanisms independent of gut microbiota [7].

2. May Help Manage Type 2 Diabetes:

Regular consumption of whole wheat may help reduce the risk of developing type 2 diabetes by improving blood sugar control [2]. Studies suggest that individuals can benefit from replacing refined grains with whole wheat products to support better glycemic control [2].

3. Helps Reduce Chronic Inflammation:

Wheat contains beneficial compounds like betaine, which may help alleviate symptoms of chronic inflammation by reducing certain inflammatory markers [4]. This anti-inflammatory action is suggested to lower the risk of chronic conditions, including heart disease and type 2 diabetes [4].

4. Prevents Gallstones:

Consuming fibre-rich foods, such as whole wheat, may help prevent gallstones [6]. The insoluble fibre in wheat may help reduce the production of bile acids, which, when concentrated, can lead to gallstone formation in the body [6].

5. Prevents Heart Attacks:

Consuming foods high in dietary fibre, such as whole grains, is consistently associated with supporting healthy blood pressure and potentially reducing the risk of recurrent heart attacks [1]. For optimal heart benefits, a whole-grain diet should be combined with regular exercise [1].

6. Prevents Breast Cancer:

Preliminary research suggests that the fibre and phytochemicals in wheat bran may offer protection against certain cancers [3]. Whole-grain wheat may also influence estrogen regulation, potentially lowering the risk of conditions like breast cancer [3].

Potential Side Effects & Risks of Wheat

While whole wheat offers benefits, its consumption poses serious health risks for some individuals, primarily due to the presence of gluten.

Celiac Disease:

This is a serious autoimmune disorder where ingesting gluten triggers an immune response that damages the small intestine lining, reducing its ability to absorb nutrients.

Non-Celiac

Wheat Sensitivity: This condition is characterized by an intolerance to wheat that causes symptoms similar to Celiac Disease (like abdominal pain, bloating, and fatigue) but does not involve the same autoimmune or allergic response [5].

Irritable Bowel Syndrome (IBS):

Wheat intolerance is common in IBS sufferers. The fermentable carbohydrates (FODMAPs) found in wheat can trigger symptoms like abdominal pain, bloating, diarrhoea, and constipation.

Allergy:

Wheat allergy is an immune reaction to specific wheat proteins, usually manifested as hives, swelling, or difficulty breathing. It is estimated that approximately 0.2% to 1% of children are allergic to wheat proteins [5].

Antinutrients:

Whole-grain wheat contains phytic acid (phytate), which is sometimes termed an “antinutrient” because it can impair the absorption of certain minerals, particularly iron and zinc, by binding to them in the gut.

Takeaway: Is Wheat Good for You?

Wheat, particularly in its whole-grain form, can offer numerous health benefits for digestion, weight management, and chronic disease risk reduction. However, for those with celiac disease, wheat sensitivity, or IBS, avoiding gluten is essential [5].

The key is moderation and choosing the correct form. Always opt for whole wheat over refined white flour for maximum nutritional value. If you experience persistent digestive issues or have known allergies, consult your healthcare professional or a registered dietitian before including wheat in your daily diet.

Expert Quote

“Whole wheat is a versatile whole grain and a powerhouse of fibre and nutrients. While it is a staple in most parts of India, those with gluten sensitivity should avoid consuming it or consult a healthcare provider before including it in their diet.”
