Hello: In response to your questions.
1.
There are many causes of diabetes, generally classified into Type 1 and Type 2.
The former accounts for 5-10% and is primarily due to the destruction of pancreatic β-cells by autoimmune antibodies or other factors; the latter accounts for 90-95% and is mainly due to insulin resistance or insufficient secretion, which is related to genetics and family history.
Of course, lack of exercise, obesity, and diets high in sugar and fat are still the main causes.
2.
Therefore, sweet potatoes are considered high in fiber and high in sugar, which, in principle, can cause an increase in blood glucose levels; however, whether they lead to diabetes is still a matter of discussion, as there are many factors that contribute to the development of diabetes.
3.
Please be cautious if your pre-meal blood glucose reaches 119 mg/dL, as this may indicate the possibility of diabetes.
It is advisable to undergo an oral glucose tolerance test and related examinations.
You may want to discuss this with your family physician or an internist.

More Info

Eating sweet potatoes can indeed impact blood sugar levels, but the extent of this effect can vary based on several factors, including the type of sweet potato, how it is prepared, and individual metabolic responses. Sweet potatoes are a complex carbohydrate that contains fiber, vitamins, and minerals, making them a nutritious choice compared to simple sugars or highly processed carbohydrates. However, they still contain carbohydrates that can raise blood sugar levels.

When you consume carbohydrates, they are broken down into glucose, which enters the bloodstream. The glycemic index (GI) of a food is a measure of how quickly it raises blood sugar levels. Sweet potatoes generally have a moderate GI, meaning they can cause a moderate increase in blood sugar. For example, a boiled sweet potato has a lower GI than a baked sweet potato, which means it may have a less pronounced effect on blood sugar levels.

For someone with a fasting blood sugar level of 119 mg/dL, which is considered prediabetes, it is crucial to monitor carbohydrate intake, including sweet potatoes. While sweet potatoes can be part of a healthy diet, portion control is essential. Eating them in moderation and pairing them with protein or healthy fats can help mitigate blood sugar spikes. For instance, having sweet potatoes with a source of protein, like grilled chicken or beans, can slow down the absorption of glucose into the bloodstream.

Additionally, the fiber content in sweet potatoes can be beneficial for blood sugar control. Fiber slows down digestion and the absorption of sugar, which can help prevent rapid spikes in blood sugar levels. Therefore, incorporating sweet potatoes into a balanced diet that includes plenty of vegetables, lean proteins, and healthy fats can be a healthy choice.

It is also important to consider individual responses to sweet potatoes. Some people may find that their blood sugar levels rise more significantly after consuming sweet potatoes than others. Keeping a food diary and monitoring blood sugar levels after meals can provide insights into how sweet potatoes affect your body specifically.

If you are concerned about your blood sugar levels and the risk of developing diabetes, it is advisable to consult with a healthcare provider or a registered dietitian. They can help you create a personalized meal plan that considers your health status, lifestyle, and dietary preferences. They may also recommend regular physical activity, which can improve insulin sensitivity and help manage blood sugar levels.

In summary, while sweet potatoes can raise blood sugar levels, they can be included in a healthy diet when consumed in moderation and balanced with other nutrients. Monitoring your blood sugar levels and working with a healthcare professional can help you make informed dietary choices that support your health and reduce the risk of diabetes.
