Have you ever wondered how carbs affect our blood sugars? Just look at all these handy sugar charts! You’ll never touch some foods again!
We all know by now how sugar in food and drink raises our blood glucose, but how many of us understand how carbs in everyday foods such as bread, cereal, granola, bananas, and rice affect us too?
Once you realise that all carbohydrates affect your blood glucose, you will understand how to make better food choices. You can also see the keto diet food chart if you wish to start a low-carb or keto diet.

How carbs affect your blood sugar (and how to make better choices)

PHC Public Health Collaboration is a charity dedicated to informing and implementing healthy decisions for better public health. They are hoping to change dietary guidelines, educate general practitioners, and improve public health. To find further information for patients and practitioners, please visit the PHC website.
How carbohydrates affect our blood glucose can sometimes be difficult to explain but Dr David Unwin has created an instantly comprehensible way to get this across by using teaspoons of sugar.
This allows healthcare professionals to inform their patients about their food choices easily in their time-constrained appointments. And even better, with these handy infographics, they can print them for their patients to stick on their fridge at home to help all the family.
However, it’s not just about healthcare professionals and patients for use, as many members of the public are handing these out to friends and family to inform them about their choices for better health. Sam Feltham, Director of the PHC.

How does breakfast affect your blood sugars?
Most people understand that if you eat a high-sugar item such as a candy bar, chocolate, sugary drink, or a slice of cake, they will raise your blood sugar immensely, but many are oblivious to the fact that many of your everyday foods such as rice, cereal, whole-grain toast, and oats, are going to raise your blood sugars just as much.
And what about a “healthy” breakfast such as small cornflakes, apple juice, with 1 slice brown toast? Well, you’re looking at your blood sugars being raised by the equivalent of 21 teaspoons of sugar.
Cornflakes 8.4 tsp + milk 1 tsp + brown toast 3 tsp + apple juice 8.6 tsp = 21 teaspoons
Now just imagine if you have a fruity yoghurt, banana, honey on a bowl of oatmeal?
Or how about a fruit-based smoothie with pineapple and mango?
How do cereal and granola affect your blood sugars?
Let’s take a quick look at “healthy cereals”?
From the previous chart, we now understand that a small 30g serving of cornflakes will raise your blood sugars by the equivalent of 8.4 teaspoons of sugar. And we all know most people like to add brown sugar, honey or canned/tinned fruit to their morning cornflakes. Spoiler alert – you’ve just created a sugar bomb!
And most people don’t serve just 30g, that’s only 1 cup!
No wonder so many of you are having an energy slump at 10m and start reaching for the vending machine to get your next sugar “fix”.
How does bread affect blood sugar?
And are wholegrain loaves of bread any better than regular white bread? I’m afraid not.
A serving of whole-grain barley bread will actually raise your blood sugars by the equivalent of 5.5 teaspoons, that’s 22g!
How does fruit affect blood sugars?
Yes, whole fruit is packed with fibre, vitamins, minerals, and many other incredible phytonutrients, but they are also high sugar and fructose.
So we can all make better choices by looking at the chart below. You may want to swap your morning banana for a bowl of nutrient-dense berries instead. You also might think twice when you reach for tropical fruits that are even higher in natural sugars.

Awesome! Thank you for this reminder. I am type 1 diabetic for 35 years. I try very hard to eat low carb. My last A1C was 6.5. ?
‘Snap!’ I’m also type 1 & have been for 33years, eating low carb for the past 10 years and reaping the benefits. I can’t understand why all diabetics aren’t encouraged to eat low carb by their educators. ‘Ditch the Carbs’ is a fantastic resource for those of us who have seen the light – and are brave enough to go against the recommended dietary guidelines for diabetics.
I totally agree…… so grateful for this resource. I cannot believe the amount of sugar in every food item. Unreal!
Carbs are everywhere and people are eating away their health unconsciously. Indeed, carbs are the macro nutrients should’ve been regulated but on the contrary losing control in nowadays diets.
Great stuff, very helpful to see it visually like this.
Good day.
Please i want to have an idea about raisins, i.e its effect on blood sugar.
They are dried fruit and very high in sugar. Best to avoid.
Where is there a definitive chart for portion sizes? A clear chart for all keto foods that shows portion breakdown in carbs, fats, proteins and sugars? ANot A Magnet sheer! Lol
That would be another looooooong article entirely. You can read portion sizes HERE, what 30g carbs look like HERE and what 30g protein looks like HERE.
I’m curious about onions. we substitute onions for potatoes and rice and
how does that measure up?
Onions, being a root vegetable, are higher in carbs. Some readers like to use onion flakes or garlic instead which lowers the carb value significantly.
Liked this site . It’s inspiring and health promoting consciousness
Wonderful and informative for a T2 like my self. Being the nerd geek that I am, I noticed that 30 g. of corn flakes will yield 33.6 g. (8.4 tsp) of sugar according to the chart.
Glad I found your site!!
Keto Chuck
