The Core Unhealthy Components of a Biscuit
At their core, most commercially produced biscuits are a combination of refined flour, sugar, and fat. This trifecta of ingredients is precisely what makes them so nutritionally poor and high in empty calories. The primary issue is not that they are inherently "poison," as some might sensationalize, but that their high-energy-density-to-nutrient-density ratio is very imbalanced.
Refined Flour
Refined flour, or maida, is the main component of many biscuits. During the refining process, the wheat grain is stripped of its bran and germ, removing most of its fiber, vitamins, and minerals. This leaves behind a simple carbohydrate that is quickly converted to sugar in the body, leading to rapid spikes in blood glucose levels. Over time, frequent blood sugar spikes can lead to insulin resistance, increasing the risk of type 2 diabetes.
High Sugar Content
From sweet cookies to seemingly innocent digestive biscuits, most commercial varieties contain a surprising amount of added sugar. Iced biscuits, for example, can contain over 40 grams of sugar per 100 grams. This excessive sugar intake contributes significantly to weight gain, increases blood pressure, and is linked to chronic inflammation, which can harm heart health. Even biscuits marketed as being for digestion or weight loss often have higher sugar and fat levels than people assume.
Unhealthy Fats
To achieve their satisfying texture and long shelf life, many biscuits are made with inexpensive fats like palm oil or partially hydrogenated oils. The latter is a primary source of artificial trans fats, which are widely recognized as detrimental to heart health. Regular consumption of trans and saturated fats raises LDL (bad) cholesterol and lowers HDL (good) cholesterol, leading to arterial blockages and an increased risk of heart attacks and strokes. A study analyzing Indian market biscuits found total fat content ranging from 9.5 to 25.0 g per 100 g, with significant amounts of saturated and trans fats.
Artificial Additives and Preservatives
To enhance flavor, color, and shelf life, manufacturers add various preservatives and artificial additives. Some of these, like the preservative TBHQ or the artificial color Tartrazine (E102), have been linked to health concerns. For example, Tartrazine has been associated with hyperactivity in sensitive children. While the use of these additives is regulated, excessive consumption can pose long-term health risks.
A Comparison of Biscuit Types
| Feature | Typical Cream Biscuit | Plain Digestive Biscuit | Homemade Whole Wheat Biscuit | 
|---|---|---|---|
| Primary Flour | Refined wheat flour (Maida) | Partially refined wheat flour | 100% Whole wheat flour | 
| Fat Source | Hydrogenated oils, palm oil | Palm oil, vegetable fats | Butter, olive oil, or coconut oil | 
| Sugar Content | High | Moderate to high | Low, often from natural sources like honey or dates | 
| Fiber Content | Very low | Low to moderate | High | 
| Additives | High (colors, flavors, preservatives) | Lower, but still present | None | 
| Nutrient Density | Low (empty calories) | Low to moderate | High (contains fiber and minerals) | 
| Key Health Concern | Weight gain, high sugar impact, cardiovascular risk | Misleading health claims, still high in calories and fat | Calorie control, but much healthier option | 
The Health Consequences of Regular Consumption
Consuming biscuits daily, especially those high in sugar and unhealthy fats, can have several negative health consequences.
- Weight Gain: The high-calorie content and lack of fiber and protein mean biscuits don't provide long-lasting satiety. This can lead to overeating and, consequently, weight gain.
- Increased Blood Sugar and Diabetes Risk: The rapid absorption of refined carbohydrates and sugar can put a strain on your body's ability to manage blood sugar, increasing the risk of type 2 diabetes.
- Cardiovascular Disease: Saturated and trans fats, common in biscuits, are known to raise bad cholesterol, contributing to heart disease. The high sodium content in some savory biscuits can also raise blood pressure.
- Digestive Issues: The lack of dietary fiber in refined flour can lead to constipation and other digestive problems.
Healthier Biscuit Alternatives and Smart Choices
While most commercial biscuits are unhealthy, you can make smarter choices or replace them entirely.
- Homemade is Best: Creating your own biscuits from scratch gives you full control over the ingredients. Use whole grain flours, reduce sugar, and replace unhealthy fats with healthier options like olive oil.
- Opt for Whole Grains: Look for commercially available biscuits made from 100% whole grains, such as oats or whole wheat, which offer more fiber and nutrients. Always check the ingredient list to ensure they haven't simply added whole grains to a base of refined flour.
- Nut and Seed Biscuits: Some brands offer biscuits made with nuts and seeds, providing healthy fats, fiber, and protein. These are more filling and nutrient-dense.
- Non-Biscuit Snacks: For a truly healthy snack, consider alternatives such as:
- Fresh fruit
- A small handful of unsalted nuts
- Whole wheat crackers with hummus or cheese
- Plain popcorn
- Greek yogurt with fruit
 
Conclusion: The Final Verdict on Biscuits
Biscuits are not a health food and are best enjoyed as an occasional treat rather than a daily snack. For most, their high content of refined flour, sugar, and unhealthy fats contributes to empty calories and various health risks, including weight gain, diabetes, and heart disease. While healthier options made with whole grains, lower sugar, and natural fats exist, a complete avoidance of biscuits in favor of more wholesome, nutrient-dense snacks is the most prudent health choice. By making informed choices and practicing portion control, you can still enjoy your favorite snacks without jeopardizing your well-being.
