Once you hit 40, your body doesn’t process carbs the same way it did in your 20s and 30s. Hormonal shifts, gradual changes in insulin sensitivity, and a naturally slowing metabolism can all make blood sugar spikes more noticeable and more damaging over time. Quick surges and crashes result in energy dips, stronger cravings, stubborn weight gain, and a higher risk of insulin resistance.
The trickiest part is that some of the biggest offenders are everyday breakfast staples that seem harmless, or even healthy. From grab-and-go granola bars to your favorite morning bagel, certain popular choices can send blood sugar soaring before your day even begins. We spoke to health experts to shed some light on four options that you should be avoiding, especially over 40.
The Difference Between Dragging Through Your Day And Feeling Great On Your Feet? These Arch Support Insoles
1. Granola Bars
Granola bars, often seen as a healthy snack, can impact blood sugar, metabolism, and insulin sensitivity. Many store-bought varieties are loaded with added sugars and processed carbs, causing a quick rise in blood sugar followed by a drop, leading to energy swings and more carb cravings. Regular consumption of these sugary snacks can slow down metabolism and may lead to insulin resistance.
"These are glorified chocolate bars without the satisfaction that you get from eating a chocolate bar," Michelle Saari, MSc, RD from eHealth project, says. She adds: "They are high in added sugar and high in calories for a very small amount. Skip the granola bars because they really aren’t adding anything to your diet. If you need a snack throughout the day try making your own trail mix with mixed nuts for protein and healthy fat, popcorn for fiber and whole grains, and a piece of fruit for fiber. This is the ultimate combination to help manage blood sugars and reduce the risk of insulin resistance."
2. Assorted Pastries
Baked treats, with their enticing scents and flavors, can impact blood sugar, metabolism, and insulin response. Items like pastries and cookies often contain high levels of refined sugars and processed carbs. These sugars digest quickly, causing a sharp rise in blood sugar followed by a crash, which may lead to energy swings and cravings. Regular intake of these carbs can also slow metabolism, complicating weight management. Saari offers her substitutes for baked treats that won't elevate your blood sugar, hinder your metabolism, or lead to insulin resistance.
"[Baked goods] are loaded with fat and sugar, none of which are beneficial for your health," she notes. "Rather than stopping at the coffee shop for a pastry, make sure that you have something prepared for yourself in the morning to grab on the go. Making some toast and putting all natural peanut butter and bananas on it. These are both better options than buying baked goods."
3. Sugary Cereals
Breakfast cereals, commonly seen as an easy choice for the morning meal, can impact health considerably. Many store-bought cereals are packed with refined sugars and processed carbs, which cause a quick rise in blood sugar when eaten. This surge is usually followed by a sudden drop, resulting in unstable energy levels and possible cravings for more carbohydrate-heavy foods. Regular intake of these cereals may also slow down metabolism over time, complicating weight control. Furthermore, frequent consumption of high amounts of refined carbs can lead to insulin resistance.
"Not all breakfast cereals are made equal, but they tend to be high in sugar without much other nutritional value," Saari reveals. "If a cereal doesn’t have fiber, then there is nothing to help regulate your blood sugars. If you want to have a morning breakfast cereal, look for one that has less than 10% of the calories from sugar, ideally there should be no sugar added to it at all. You can help to regulate your blood sugars by eating it with chopped fruit for a source of fiber, and milk which is a good source of protein. By having protein and fiber with foods it can help to slowly release sugar to your blood steam which helps to control blood sugar spikes," Saari says.
4. Bagels
Generally crafted from refined wheat flour, bagels are missing the fiber present in whole grains, leading to a quick rise in blood sugar levels after eating. This rapid increase triggers the body to release insulin to control blood sugar, which may result in greater fat storage. Moreover, bagels can be quite calorie-dense and might not offer the lasting sense of satiety that fiber-rich, nutrient-packed foods do.
"Bagels are a very dense refined carbohydrate with around 50g of carbs per bagel. They are made typically with high glycemic flour which is digested quickly and can spike your blood sugars. Additionally, the high carb content is what gives bagels hundred of calories which can lead to an increase in body weight," Jesse Feder, RDN, CPT, tells us.
