When it comes to managing blood sugar levels, diet plays a crucial role. Certain foods have a significant impact on our body's ability to regulate glucose levels, and some of these can be quite surprising. Here are 20 common culprits that can cause your blood sugar levels to skyrocket.
The Sweet Toxin: Refined Sugars
Refined sugars are the ultimate enemy when it comes to maintaining healthy blood sugar levels. Consuming high amounts of refined sugars, such as those found in white bread, pasta sauce, and sugary drinks like soda and sports beverages, can cause a rapid spike in blood sugar levels. A study published in the Journal of Clinical Endocrinology & Metabolism found that consuming just 25 grams of glucose (about 6 teaspoons) resulted in significant increases in fasting insulin levels.
The Sneaky Sinner: Processed Meats
Processed meats like hot dogs, sausages, and bacon are not only high in sodium but also contain advanced glycation end (AGE) products. AGEs are substances that form when protein or fat is cooked at high temperatures and can contribute to oxidative stress, inflammation, and insulin resistance.
The White Wonder: White Rice
White rice is a staple food for many cultures around the world, but it's often made from refined flour that lacks fiber and nutrients. Consuming large amounts of white rice can lead to an imbalance in blood sugar levels due to its high glycemic index (GI). A study published in the Journal of Nutrition found that consuming 50 grams of cooked white rice resulted in significant increases in postprandial glucose levels.
The Fattening Friend: Fried Foods
Fried foods like french fries, fried chicken, and doughnuts are often high in calories, fat, and sugar. These food items can cause a rapid spike in blood sugar levels due to the presence of unhealthy fats that impair insulin signaling pathways.
The Breakfast Bumbler: Sugary Cereals
Even seemingly healthy breakfast options like sugary cereals can wreak havoc on your blood sugar levels. Consuming foods high in added sugars, such as some popular brands of cereal, can lead to an increase in fasting glucose levels and contribute to the development of insulin resistance.
The Juicy Jolt: Fresh Fruit Juice
While whole fruits are nutritious and a great source of fiber and antioxidants, fruit juice concentrates have been stripped of their beneficial fibers. Drinking high amounts of fresh fruit juice daily can cause blood sugar spikes due to its natural sugars content.
Baked Goods Bonanza: Cakes, Cookies, and Pastries
The combination of refined flours, added sugars, and unhealthy fats in baked goods like cakes, cookies, and pastries makes them a perfect storm for high blood sugar levels. A study published in the Journal of Clinical Endocrinology & Metabolism found that consuming just one serving (about 1 ounce) of such foods can result in significant increases in fasting glucose levels.
The Sugar-Loaded Snack: Energy Bars
Energy bars, often marketed as a healthy snack option, are typically high in added sugars and low in essential nutrients. Consuming these energy-dense snacks daily can lead to an imbalance in blood sugar levels due to the presence of unhealthy carbohydrates that cause insulin resistance.
Savory Treats That Can Derail Your Blood Sugar: Cheese Platter
Even seemingly healthy foods like cheese, crackers, and fruits can be detrimental when consumed excessively. The high-fat content in these snacks impairs glucose uptake by skeletal muscle cells and increases fasting blood sugar levels.
These are just a few of the many food culprits that can cause your blood sugar levels to soar. By limiting or avoiding such foods altogether, you may be able to achieve better blood sugar control.
Learn how Dr. James O’Keefe, Director of Preventive Cardiology at the Mid America Heart Institute believes that lifestyle changes + adding the psyllium fiber in Metamucil to your diet can help you lower your bad cholesterol levels†. Learn more here: In your body, cholesterol is used to make bile acids in the liver. Bile acids are released into the gut to promote digestion of the fat in the food you eat. The body typically absorbs bile acids to be used again. However, the psyllium in Metamucil forms a thick gel, which traps some bile acid, so not as much is re-absorbed. These trapped bile acids are removed in your body’s waste. In response, the liver removes LDL cholesterol from the blood stream, to make more bile acid, and this results in less LDL or bad cholesterol in the blood!
