When it comes to managing blood sugar, looks can be deceiving. Many foods marketed as “healthy” can actually cause your glucose levels to spike more quickly than a slice of chocolate cake. According to New Jersey-based endocrinologist Dr. Alessia Roehnelt, several everyday breakfast staples may seem nutritious but can have surprisingly high glycemic indexes.
Dr. Roehnelt explained that chocolate cake typically raises blood sugar levels between 38 to 45, which is considered a moderate range. However, certain foods people perceive as wholesome can raise glucose levels dramatically — some reaching spike ranges between 60 and 90.
1. Instant Oatmeal Packets
Instant oats are often chosen for their convenience, but Dr. Roehnelt warns they are highly processed and can trigger a sharp blood sugar surge. The glycemic spike from instant oatmeal can range between 79 and 83, making it one of the highest among breakfast foods. To make it healthier, she suggests preparing it with milk instead of water, as the added fat and protein help slow the sugar rise.
2. Oat Milk Latte
Oat milk may seem like a clean, dairy-free alternative, but it’s not as blood sugar–friendly as it appears. Dr. Roehnelt explains that oat milk is produced by enzymatically breaking down oats, giving it a high glycemic index. Combined with sweeteners in coffee, the oat milk latte can lead to a glycemic spike between 65 and 75. For a better alternative, she recommends using almond milk, which has a lower impact on glucose levels.
3. Acai Bowls
The vibrant and colorful acai bowl looks like the perfect healthy meal — but it’s actually one of the biggest culprits for raising blood sugar. With a glycemic index of 70 to 90, this fruit-heavy meal can quickly push blood sugar to high levels. “These bowls often have a high fruit-to-protein ratio,” Dr. Roehnelt explains. “When you top them with juices, honey, or granola, it increases the spike even more.”
To make acai bowls healthier, she suggests adding a scoop of yogurt or a handful of nuts to balance the sugar content with protein and healthy fats.
Dr. Roehnelt also cautioned that starting your morning with such foods can trigger a rapid sugar spike followed by a crash, leaving you fatigued throughout the day. She emphasizes the importance of balancing carbohydrates with protein and fiber to maintain stable blood sugar levels.
