Unlocking the Secrets: How Non-Sweet Foods Can Still Raise Blood Sugar Levels

Updated on & Medically Reviewed by Dr Lalitha

When it comes to blood sugar levels, many people associate spikes with sweet-tasting foods. However, the truth is that the taste of sweetness is not the sole factor that influences blood sugar. Here, we'll explore the broader aspects of blood sugar regulation and debunk the myth that only sweet foods can cause significant spikes.

Different Factors that Cause Spike in Blood Sugar Levels:

Understanding the various factors involved can help you make informed choices about your diet and manage your blood sugar levels effectively.

1. Impact of Carbohydrate Foods on Blood Sugar Levels:

Carbohydrates, regardless of taste, play a crucial role in blood sugar spikes. Whether they come from sweet or savory sources, carbohydrates are broken down into glucose, the primary source of energy for our bodies. Foods high in carbohydrates, such as fruits, grains, and legumes, can raise blood sugar levels.

Following fruits are not very sweet but still have a relatively high glycemic index.

A) Watermelon:

Watermelon has a high glycemic index despite its mild sweetness. It contains a significant amount of natural sugars and is relatively low in fiber, which contributes to its impact on blood sugar levels.

B) Pineapple:

Pineapple is another fruit that is not excessively sweet but has a high glycemic index. It contains natural sugars and has a lower fiber content, which can lead to a faster rise in blood sugar levels.

C) Ripe Bananas:

While unripe or green bananas have a lower glycemic index due to their higher starch content, ripe bananas with brown spots have a higher glycemic index. As bananas ripen, their starches convert into sugars, making them sweeter and contributing to their impact on blood sugar levels.

2. Processed and Refined Foods:

Processed and refined foods, such as white bread, crackers, and sugary cereals, often lack a strong sweet taste but can still lead to a rise in blood sugar levels. These foods typically contain refined carbohydrates that are quickly digested and absorbed, causing a sharp increase in blood sugar. Additionally, they often lack fiber, healthy fats, and protein, which can help slow down the absorption of sugar into the bloodstream.

3. Glycemic Index and its Impact:

The glycemic index (GI) ranks carbohydrates based on their potential to raise blood sugar levels. High-GI foods like sugary snacks cause rapid blood sugar spikes, while low-GI foods like whole grains lead to a slower rise. However, the glycemic index is just one piece of the puzzle.

Some examples of high glycemic index, non-sweet foods:

A) White Rice:

White rice, despite not being sweet, has a high glycemic index. The exact GI value can vary depending on the type of rice and the cooking method, but on average, it ranges from 70 to 73.

B) White Bread:

White bread is another non-sweet food with a high glycemic index. The GI of white bread is typically around 70 or higher, indicating its potential to raise blood sugar levels rapidly.

C) Cornflakes:

Cornflakes, which are commonly consumed as breakfast cereal, have a high glycemic index. The GI of cornflakes can be around 81, making them a food that can quickly increase blood sugar levels.

D) Pretzels:

Pretzels are a savory snack option that may not taste sweet but has a high glycemic index. The GI of pretzels can range from 83 to 91, depending on the brand and ingredients.

E) Rice Cakes:

Rice cakes, often considered a low-calorie snack, can surprisingly have a high glycemic index. The GI of rice cakes can vary, but it typically falls within the range of 77 to 87.

These foods highlight that the sweetness of food is not the sole determinant of its glycemic index.

Other Factors that Influence GI Value:

Apart from the above mentioned foods, there are some other factors, such as the type of carbohydrate, processing, and cooking methods, can also influence the GI value. Let’s see how they influence the GI value.

a) Food Composition:

Combining carbohydrates with protein, fiber, and good fats helps slow down the absorption of glucose and causes blood sugar levels to rise more gradually. Spikes can be lessened by eating a piece of fruit with nuts or including vegetables in meals high in carbohydrates.

b) Cooking and Processing:

The way food is prepared has an effect on how blood sugar reacts. White flour and white rice, which are highly processed or finely ground, are digested more quickly and can result in sudden rises in blood sugar levels. Choosing whole grains and utilizing softer cooking techniques like steaming or baking will help.

c) Personalized Approach:

Be aware that everyone reacts to food differently. Even though they are not normally high in carbohydrates or sweetness, certain foods might cause noticeable blood sugar rises in some people.

d) Portion Control:

The quantity of food you consume influences blood sugar response. Even if a food has a moderate impact on blood sugar, large portions can still lead to significant spikes. Practicing portion control is vital for managing blood sugar levels, regardless of taste.

It's worth noting that these foods are not necessarily unhealthy, but they may lead to a faster rise in blood sugar levels. Pairing them with protein, healthy fats, or high-fiber foods can help mitigate their impact on blood sugar spikes. Portion control and moderation are essential to healthy eating.

Now, let's see the benefits of consuming low-GI foods.

Benefits of Consuming Low Glycemic Index (GI) foods:

1. Slower Digestion and Absorption:

Low GI foods are digested and absorbed more slowly, resulting in a gradual and steady release of glucose into the bloodstream. This helps prevent rapid spikes in blood sugar levels, providing more stable energy levels and reducing the strain on insulin production.

2. Improved Insulin Sensitivity:

Low GI foods have been associated with improved insulin sensitivity. By choosing foods that have a lower impact on blood sugar, individuals with prediabetes can potentially enhance their body's response to insulin and improve blood sugar control.

3. Sustained Energy and Satiety:

Low GI foods often contain more fiber, healthy fats, and protein, which contribute to increased satiety and sustained energy levels. This can help prevent overeating, promote weight management, and reduce the risk of developing type 2 diabetes.

It is advisable to maintain ideal blood sugar levels to avoid multiple chronic and lifestyle health issues.

There is a natural, safe, and effective way to reduce the Glycemic effects of food. A good option to lower the blood glucose after having a carb-rich meal or high GI food is moder/ate (Moderate). It is a natural plant extract that helps lower post-meal blood sugar spikes.

Need proof to be convinced. Eat a carb-rich meal on a day and check your blood sugar levels approximately 45 min later. Take a tablet of Moderate 10 minutes before the same meal the next day, and check can show your blood sugar levels approximately 45 min later. You will see a noticeable decrease. You'll observe reduced blood sugar spikes despite consuming the same food, as Moderate Tablet effectively decreases post-meal sugar and carbohydrate load by up to 40%. Enjoy stable blood sugar levels, avoid sugar spikes and crashes, and prevent hunger pangs. Moderate Tablet also promotes gut health by nourishing beneficial gut bacteria. Simply take it before meals to slow down carbohydrate breakdown, limit glucose absorption, and improve overall well-being.



Q) Can non-sweet foods also raise a spike in blood sugar values?

A) Yes, non-sweet, but Carbohydrate-rich foods like white rice, white bread, etc can cause a spike in blood sugar values.

Q) Is the Glycemic Index high only for sweet-tasting foods?

A) No, The Glycemic Index can also be high for non-sweet tasting foods like white rice, white bread, etc.

Q) Can we reduce the Glycemic Index of foods?

A) Yes, the Glycemic index of foods can be reduced if you combine them with proteins, fats, and fiber-rich foods. Also, the Glycemic index will partly depend on the amounts consumed and a person’s metabolism too.

Q) Consuming low Glycemic Index foods will help with maintaining energy levels throughout the day.

A) Yes, low Glycemic Index foods will help with maintaining energy levels throughout the day by helping you avoid a ‘Sugar Crash’.
