Cassava vs. Potato: A Nutritional Breakdown
Cassava (also known as yuca or manioc) and potatoes are both starchy root vegetables, and their inherent nutritional profiles differ. Understanding these differences is the first step in comparing their processed chip forms. Cooked cassava offers a good source of vitamin C, resistant starch, and fiber. Its resistant starch, in particular, feeds beneficial gut bacteria, potentially supporting digestive health and blood sugar management. On the other hand, potatoes are known for providing more protein, potassium, and a higher water content in their raw form.
The Impact of Processing on Nutrition
Once processed into chips, the nutritional story changes dramatically. The healthiness of any chip—whether from cassava or potato—depends heavily on the cooking method and the type of oil used. Deep-frying drastically increases calorie and fat content, often outweighing any potential benefits from the original vegetable. Quality brands that bake their chips or fry them in clean, high-heat oils like avocado or coconut oil with minimal additives can offer a more nutritious product. In general, though, cassava can have more carbohydrates and calories than a potato, but may also contain more fiber.
Comparison of Chips: Cassava vs. Potato
To provide a clearer picture, here is a comparison based on typical nutritional profiles, recognizing that values will vary by brand and preparation method.
| Nutrient (per 100g) | Typical Potato Chips | Typical Cassava Chips |
|---|---|---|
| Calories | ~536 kcal | ~482 kcal |
| Carbohydrates | 49g | 63g |
| Fiber | 3.8g | 4.8g |
| Protein | 6.8g | 3.3g |
| Resistant Starch | Yes (when cooled) | Yes (higher content) |
| Gluten-Free | Yes | Yes |
Important Health and Safety Factors
Beyond the raw nutritional comparison, there are critical health factors to consider when choosing between these snack foods.
Resistant Starch and Gut Health
Cassava's primary health-related advantage is its high resistant starch content, which functions much like soluble fiber. It feeds the healthy bacteria in your gut, leading to the production of short-chain fatty acids like butyrate, which can reduce inflammation and support overall digestive health. While potatoes also contain resistant starch, particularly when cooked and then cooled, cassava generally offers a more significant amount. It is important to remember that processing can lower this content, so home-cooked or minimally processed options are best.
Lead Contamination: A Serious Concern
In May 2025, Consumer Reports published a damning investigation revealing that many cassava-based products, including chips, contained alarmingly high levels of lead. This was attributed to cassava's tendency as a root vegetable to absorb heavy metals from contaminated soil. The risks associated with lead exposure are severe, particularly for children, affecting neurological and developmental health. Consumers should exercise extreme caution and consider this risk when purchasing commercial cassava products. The variability of lead levels between different products in the study highlights the importance of choosing brands that test their products for heavy metals.

The Cyanide Issue
Cassava in its raw form contains cyanogenic glycosides, which can release toxic cyanide into the body. Proper soaking and cooking, such as boiling or high-heat frying, is necessary to make it safe for consumption by destroying these harmful compounds. The good news is that commercial processing for chips and flours typically handles this adequately, making the final products safe in this regard. However, this is a major reason why homemade preparation must be done correctly.
The Healthiest Choice: Baked at Home
To mitigate the risks of both cyanide (via proper preparation) and heavy metal contamination (by controlling your source), making homemade baked cassava chips is the healthiest option. By thinly slicing the root, lightly coating it in a clean oil, and baking it in the oven or air fryer, you retain more nutrients and avoid the unhealthy additives and potentially contaminated ingredients found in some commercial products.
Conclusion: The Final Verdict
So, are cassava chips healthier than normal chips? The answer is nuanced. On a purely nutritional basis, particularly considering resistant starch and fiber content, cassava chips from quality, clean brands may have a slight edge over standard, heavily processed potato chips. However, the serious and proven risk of lead contamination in some commercial cassava products, as reported by Consumer Reports, adds a major health and safety caveat. This makes the choice less straightforward than simply comparing calories or fiber. For consumers, the safest and healthiest approach is to either make your own chips from properly sourced cassava or choose commercially produced versions from reputable brands that can guarantee heavy metal testing. Always prioritize ingredient transparency and minimal processing over marketing claims to ensure you're making a truly healthier choice.
