Blood Sugar After Eating

After consuming a meal, your blood sugar levels start to rise within quarter to half an hour only if the meal included carbohydrates. The level and speed of the increase is determined by the type of carbohydrates and other nutrients in the food you eat. Your body’s blood sugar level management ability will also impact the level and speed of blood sugar.


The main component of food that can raise you blood sugar levels is carbohydrates. The type and amount of carbohydrates you consume will have a great impact on how fast your blood sugar levels change after a meal. Carbohydrates from liquids like soft drinks and juices are normally digested faster. Carbohydrates from solid foods like fruits and pasta take longer to break down. Food such as nuts, cheese, fish, meat, eggs and butter do not influence your blood sugar levels significantly because they contain no or little carbohydrates.

Glycemic index

Foods that contain carbohydrates are the only ones with a glycemic index. The index is used to evaluate how high and quickly your blood sugar levels rise in response to various foods. Plenty of high-glycemic foods have the ability of raising your blood sugar levels within 15 minutes of eating. A more modest effect on levels of blood sugar in your body is experienced after eating low glycemic foods.

Mixed, fiber and fat meals

Combining other foods with foods containing carbohydrates will normally slow down the rise of your blood sugar levels. For example, protein, fiber and fat all have the ability of delaying gastric emptying. The increase in your blood sugar level is delayed when it takes more time for your stomach to digest food before releasing the same to your intestines. For instance, if you consume high glycemic foods with a serving of chicken, extra vegetables and butter, your blood sugar levels will rise slowly.

Blood sugar testing

People are different and the pace at which levels of blood sugar rise after eating is dependent on the state of your health. The pace will also be determined by whether you exercise after a meal, if you are diabetic or are insulin resistant. It is prudent to ask your primary physician to get you a glucometer if you are concerned with your blood sugar levels. It is a convenient gadget that can effectively measure your blood sugar at home. Use it before eating and every quarter of an hour to two hours after a meal.

My diet is pretty good though I don’t excercise much. If I drink 5 Mountain Dew reds and eat at a buffet my sugar will drop drastically between 38mg to 86mg. Why???? Is it poor metabolism????

    I’m 35, 5’4, 113 pounds. Today my diet has almost zero refined sugar in it. I drink water and milk only. My dessert is white bread with butter. This is because a small amount of sugar gives me a 2-3 day migraine. BBQ sauce does this to me.
    I don’t understand it. My doctors keep brushing me off like nothing is wrong.
    I got a glucose meter last night and thus far it’s been 113, 132, 152, 131.
    If it’s not diabetes that make me THIS sensitive to sugar, then what is it??!!
