What's more unhealthy, crisps or sweets?

While most people consider sugary treats the most damaging to their health, experts often point out that the high starch content in crisps can be even worse for dental health. The debate over what's more unhealthy, crisps or sweets, involves examining more than just calories.

Quick Summary

This nutritional breakdown compares the primary health risks associated with consuming crisps and sweets, analyzing sugar, salt, and fat content to reveal which snack poses a greater threat to your overall well-being.

Key Points

• Sodium and Saturated Fat: Crisps are particularly high in sodium, which raises blood pressure, and saturated fats, which harm heart health.

• Added Sugar: Sweets are loaded with added sugar, causing blood glucose spikes, inflammation, and increasing the risk of type 2 diabetes.

• Dental Damage: Starchy crisps can be worse for teeth than some sweets, as they stick to crevices and cause prolonged acid attacks on enamel.

• Low Nutritional Value: Both crisps and sweets offer very few nutrients and are considered 'empty calories' that displace healthier foods.

• Prioritise Whole Foods: The healthiest choice is to replace both crisps and sweets with nutrient-dense, whole-food alternatives like fruits, vegetables, nuts, and plain yoghurt.

• Portion Control Issues: Ingredients like MSG in crisps and the addictive nature of sugar in sweets can make overconsumption a significant problem.

Deconstructing the Unhealthiness of Crisps

When we talk about crisps, we're primarily looking at processed potato or other root vegetable snacks, typically deep-fried and heavily salted. The primary nutritional culprits here are high levels of sodium, saturated fat, and starchy carbohydrates. The refining process strips away most, if not all, beneficial nutrients, leaving a calorie-dense food that provides minimal satiety.

The high sodium content is a significant health concern. Excessive salt intake can lead to elevated blood pressure, increasing the risk of heart disease and stroke. Additionally, the saturated fats used in the frying process contribute to unhealthy cholesterol levels. The starchy nature of crisps also poses a specific threat to dental health. As plaque bacteria break down the starches, they produce acid that attacks tooth enamel for an extended period, potentially more so than sugar from some sweets.

The Impact of Processing on Crisps

The industrial processing of crisps often involves high-temperature frying, which can create acrylamide, a chemical compound linked to cancer in animal studies. Furthermore, the use of monosodium glutamate (MSG) in some flavourings is known to be addictive and can affect satiety signals, leading to overconsumption. Portion control is particularly challenging with crisps due to their palatable, crunchy texture and addictive ingredients.

Unwrapping the Dangers of Sweets

Sweets, or candies, are defined by their high sugar content. This can include added sugars, corn syrup, and other sweeteners. The core issue with sweets is the rapid spike in blood glucose levels they cause, which can lead to inflammation and contribute to conditions like type 2 diabetes and poor overall health.

Beyond the sugar, many sweets contain saturated and trans fats, especially those with chocolate or creamy fillings. These contribute to weight gain and heart problems. For dental health, while the effect can be more immediate, some sweets that dissolve quickly may be less damaging than the starches found in crisps that stick to teeth for longer. However, constant exposure to sugar accelerates bacterial acid production, which is the primary cause of cavities.

The Allure of Sugar and Its Consequences

Sugar is well-known for its addictive properties, affecting the brain's reward system. This can lead to cravings and a cycle of dependency. For this reason, moderating sweet consumption can be a real challenge. While a packet of crisps may contain a comparable number of calories to a bar of chocolate, the source of those calories—saturated fat and sugar in sweets versus sodium and starch in crisps—presents different health challenges.

Crisps vs. Sweets: A Comparative Table

Health Aspect	Crisps	Sweets
Primary Concern	High Sodium & Saturated Fat	High Added Sugar & Saturated Fat
Cardiovascular Risk	High sodium increases blood pressure.	Saturated fats and inflammation linked to sugar impact heart health.
Dental Health	Starchy carbohydrates stick to teeth, causing prolonged acid attacks.	Sugar fuels bacteria, causing rapid acid production and cavities. Less risk if they dissolve quickly.
Processing Byproducts	Potential for acrylamide from high-heat cooking.	Often contain artificial colors, preservatives, and high-fructose corn syrup.
Addiction Potential	Can contain MSG and are highly palatable, leading to overconsumption.	Sugar's effect on the brain's reward system is well-documented, leading to cravings.
Nutritional Value	Extremely low; high in calories, low in vitamins and fibre.	Extremely low; high in empty calories. Some dark chocolate can have antioxidants.

Making a Healthier Choice

Ultimately, neither crisps nor sweets offer significant nutritional value and should be consumed in moderation. However, if forced to choose between the two, it often comes down to the individual's specific health vulnerabilities. Someone with high blood pressure may be better off avoiding the high sodium in crisps, while a person at risk of diabetes should be more wary of sweets due to the sugar content.

Here are some better snacking alternatives to consider:

• Fruits and Vegetables: Provide vitamins, minerals, and fibre. Consider apple slices with a tablespoon of nut butter or carrot sticks with hummus.
• Nuts and Seeds: Offer healthy fats and protein to keep you feeling full longer. A small handful of almonds or walnuts is an excellent choice.
• Yoghurt: Plain Greek yoghurt is high in protein and can be topped with berries for a touch of natural sweetness.
• Air-popped Popcorn: A whole-grain snack that is much lower in calories and fat than crisps when prepared without excessive butter and salt.
• Dark Chocolate: In moderation, dark chocolate (70% cocoa or higher) has antioxidant properties and less sugar than milk chocolate.

Conclusion: No Clear Winner, Just Healthier Habits

There is no single definitive answer to the question of what's more unhealthy, crisps or sweets. Both categories of food are highly processed, calorie-dense, and lacking in nutritional benefits. The primary health concern differs—crisps are typically higher in salt and saturated fat, while sweets are overwhelmingly high in sugar. The best approach for optimal health is not to try and determine which is the lesser of two evils but to reduce the intake of both in favour of nutrient-dense, whole-food alternatives. Your body will thank you for choosing a piece of fruit over a bag of crisps or a bar of chocolate.

The True Cost of Processed Snacks

Regardless of your preference for savoury or sweet, processed snacks play a detrimental role in a healthy diet. They displace more nutritious food choices and contribute significantly to high calorie intake without providing the essential vitamins and minerals your body needs to function properly. The debate isn't really 'crisps versus sweets' but rather 'processed versus whole foods.' Choosing snacks closer to their natural state, like a piece of fruit or a handful of nuts, is always the healthier option.

Frequently Asked Questions

Which snack is worse for my teeth, crisps or sweets?

Starchy snacks like crisps can be worse for your teeth because the starch breaks down into sugar that sticks to your teeth for a longer time, fueling bacteria that produce harmful acid.

Is there more sugar in crisps or sweets?

Sweets contain a far higher concentration of added sugar than crisps, which are primarily defined by their high sodium and fat content. However, the carbohydrates in crisps convert to sugars during digestion.

How do crisps and sweets affect heart health differently?

Crisps primarily impact heart health through their high sodium content, which elevates blood pressure. Sweets can contribute through saturated fats and systemic inflammation caused by high sugar intake.

Are there any 'healthy' crisps or sweets?

While some products market themselves as healthier, most crisps and sweets are highly processed. A healthier choice would be to opt for minimally processed snacks like air-popped popcorn, nuts, or fruit to satisfy a craving.

Which is more likely to cause weight gain?

Both crisps and sweets are calorie-dense and can lead to weight gain when consumed excessively. The deciding factor is often the portion size and frequency of consumption rather than the type of snack.

What's a better alternative to crisps or sweets?

Instead of crisps or sweets, opt for whole-food snacks such as fresh fruit, vegetable sticks with hummus, a handful of nuts, or plain Greek yoghurt with berries.

Does eating crisps lead to the same blood sugar spike as sweets?

While the impact is different, the refined carbohydrates (starches) in crisps can also cause a significant increase in blood glucose levels, similar to sugar, although perhaps not as rapidly.
