Which Vegetables Should Be
Avoided in Diabetes?
For individuals managing
diabetes, diet plays a
critical role in maintaining stable blood sugar
levels. While vegetables are generally
considered healthy, some can significantly
impact glucose levels due to their carbohydrate
content. Starchy vegetables are the primary
culprits, and understanding which ones to limit
or avoid is crucial for effective diabetes
management. The core vegetables that should be
approached with caution include potatoes (both
regular and sweet), corn, peas, and butternut
squash. These vegetables are higher in
carbohydrates than other non-starchy options,
which can lead to elevated blood sugar levels if
consumed in large portions. Therefore, mindful
consumption and portion control are essential.
Understanding Starchy vs.
Non-Starchy Vegetables
It’s important to distinguish between starchy
and non-starchy vegetables when managing
diabetes. Starchy vegetables are high in
carbohydrates that the body breaks down into
glucose, causing a more pronounced impact on
blood sugar levels. Non-starchy vegetables, on
the other hand, contain fewer carbohydrates and
more fiber, leading to a slower and steadier
release of glucose.
The Impact of Carbohydrates
Carbohydrates are the primary macronutrient that
affects blood glucose levels. When you consume
carbohydrates, your body breaks them down into
glucose, which enters the bloodstream. In people
with diabetes, either the body doesn’t produce
enough insulin (type 1 diabetes) or doesn’t use
insulin effectively (type 2 diabetes). This
leads to higher levels of glucose in the blood.
Starchy vegetables, due to their carbohydrate
load, can exacerbate this issue.
1. Carrot
Carrots, called by the name ‘Gajar’ in Hindi, are a high
Glycemic Index food. We all know that carrot is a
modification of root and is a kind of root vegetable.
The Glycemic Index value of gajar is 71, which is
ultimately a high Glycemic Index value.
It is suggested that diabetic patients only take 45-60
grams of raw carrots in a single meal to avoid
instability in their blood sugar levels.
Please note, when we cook carrots, the GI values
increase. So, if you have carrots in the cooked form,
make sure to add low Glycemic food.
If we consider a single medium-sized carrot, it would
contain approximately 10.5 grams of Carbohydrates and
have a 7.5 Glycemic load.
2. Potatoes
The Glycemic Index value of potatoes is very high. We
all know that the GI value above 70 makes vegetables a
bad option for diabetic patients. Thus potatoes are not
suitable for diabetic
patient health as potatoes GI value ranges from 58
to 111.
If average values are considered, then the GI value of
boiled potatoes is 78, and the GI value of cooked
potatoes is 87.
Potatoes raise sugar levels in the body. So, one must
keep in mind to take adequate amounts of potatoes in the
diet if they have diabetes.
Apart from being a high Glycemic Index food, potatoes
possess some good nutritional content.
Potatoes are rich in vitamins and minerals, including
potassium, Vitamin B6, Vitamin C, copper, phosphorus,
dietary fiber, manganese, pantothenic acid, etc.
3. Beetroot
Beetroots have a Glycemic Index value of 61, which is a
moderate Glycemic Index value.
The Glycemic Index value helps us to determine how the
food raises blood sugar levels in the body. If the food
has a high Glycemic Index value, it will raise blood
sugar levels in the body, and if a food has a low
glycemic index value, it will not raise blood sugar
levels in the body.
The beetroots come in different types of varieties. We
can differentiate different varieties of beetroot by
their color. The beetroot comes in different colors like
pink, white, yellow, or dark purple.
Additionally, beetroots are rich in vitamins and
minerals like manganese, folate, iron, potassium,
vitamin C, etc.
Apart from this, beetroot also possesses many health
benefits like lowering blood pressure in the body and
increasing stamina for exercise.
4. Pumpkin
Pumpkins have a Glycemic Index value of 75, which is a
high Glycemic Index value.
However, the glycemic load of pumpkins is low and is
only 3 in value.
By going through the values of the Glycemic Index and
the Glycemic load of pumpkins, we get to know that one
can eat pumpkins in limited quantities if they wish to
stay healthy. The higher amounts of pumpkins can
increase blood sugar levels in the body.
The content of calories in pumpkin is very low, which
made this food item very useful.
People prefer to add pumpkins to their diet because the
calorie content is less, and on top of that, it is full
of nutrients,
which allows any person to stay fit.
However, people who have diabetes should
avoid pumpkins a bit because of their Glycemic Index
value.
5. Yam
The carbohydrate content in yam is very high, so its
high Glycemic Index value is 51.
If someone is consuming large amounts of yams in their
diet, it can raise the body’s blood sugar levels.
The carbohydrates present in yams are dissolved very
quickly in the bloodstream and thus fluctuate blood
sugar levels.
It is advised that diabetic patients add yam in limited
quantities to their diets to harm their health.
6. Tapioca and Cassava
Tapioca has a high value of existing nutrient
carbohydrate content, which results in the increment of
blood sugar levels. Based on HbA1c levels, sometimes
people with diabetes can eat moderately.
However, add other vegetables too in it or increase the
content of fiber in the diet of the whole food resulting
in high blood sugar levels. Due to this reason, try to
add a diet that has a low glycemic index to prevent
health complications that relate to diabetes.
Insulin is a hormone that helps if you have diabetes;
eating fiber-rich foods may help lower your blood.
Ingredients like Tapioca which has a high glycemic
index, so blood sugar rises quickly after consuming it.
Cassava also possesses a high Glycemic Index value of
approximately 94.7. Diabetic patients are suggested to
eat it in limited amounts so that it will not affect
their health. The high Glycemic Index value causes an
immediate rise in blood sugar levels, leading to
problems like metabolic syndrome, obesity, etc.
7. Turnips and Rutabagas
Turnips have a high Glycemic Index value that is 62.
That’s why, by having turnips, sugar levels in the body
can rise. These are rich in carbohydrates,
and this is the main reason for their high Glycemic
Index value. However, this value can be reduced if we
add some proteins with turnips in the diets. The
proteins will help to control the sudden increase in
blood sugar levels.
Rutabagas also have a high Glycemic Index value of 72,
which can increase blood sugar levels in the body. It is
recommended that diabetic patients eat Rutabagas in
limited quantities as this vegetable can adversely
affect their health. Carbohydrates content is very high
in this vegetable, and thus Rutabagas is not considered
an ideal food for any diabetic
patient.
8. Radish
Raphanus sativus, which is commonly called by the name
Radish, is a type of root vegetable. People prefer to
eat this vegetable all over the world. Hence, one should
know its effects on diabetic patients.
It is recommended not to eat radish in higher amounts if
you have diabetes.
The Glycemic Index value of radish is moderately high,
and the high Glycemic Index food is usually not
recommended for any diabetic patient.
9. Parsnips
The Glycemic Index value of Parsnips vegetables is very
high, approximately 72.
However, one should note that Parsnips contain almost no
sugar in them, and thus this makes a safe choice for
some diabetic patients.
Additionally, Parsnips can act as antioxidants in the
body and can help in reducing weight. It also boosts the
functioning of the immune system. The body’s immune
system helps us fight any disease, and this vegetable
helps us strengthen our immune system.
Apart from this, Parsnips are also rich in minerals like
fiber and thus are very beneficial for us.
10. Sweet Corn
The Glycemic Index value of sweet corn is relatively
high, and thus sweet corn is a wrong choice for any
diabetic patient.
The food crops which have high Glycemic Index values are
not recommended for diabetic patients. This food can
raise blood sugar levels in the body very quickly.
If any diabetic patient includes sweet corn in their
diet, they have to make sure of proper precautions as it
can harm their health.
However, sweet corn has some benefits too:
keeps away chronic diseases
help to improve the digestion of the body and much
more.
11. Jerusalem artichoke
This vegetable has a lower Glycemic Index value than
potatoes. However, the value is moderately high.
Including Jerusalem artichokes in regular diets for a
longer duration can help a diabetic patient stay healthy
and safe for diabetic patients.
150grams of Jerusalem artichokes may contain 115
calories, 25.0g carbohydrates, 2.5g fiber, 15.0g sugar,
and almost no fat content.
Jerusalem artichokes have many benefits.
Some of them
are:
help to improve digestion
lower the cholesterol levels in the body help in the
formation of Red blood cells and hence provide
energy to the body.
12. Horseradish
Consuming lesser amounts of horseradish is beneficial.
However, if higher amounts of horseradish are eaten, it
may cause fluctuations in the body’s blood sugar levels.
If eaten in higher amounts, then blood sugar levels may
get high and lead to weight gain.
Horseradish is very beneficial in limited quantities and
has many health benefits too.
Some benefits of
horseradish include:
Horseradish prevents cancer
Strengthen the immune system of the body
Improves digestion
13. Sweet potatoes
The Glycemic Index value of sweet potatoes depends on
the way it has been taken in the diets. In other words,
the GI value of sweet potatoes differs in different
forms. Sweet potatoes can be included in diets in 4
different forms.
Boiled:
When we boil sweet potatoes, their Glycemic Index value
decreases. For example: When potatoes are boiled for 8
minutes, their GI value is 61, whereas when we allow it
to boil for 30 minutes, their GI value changes to 46,
which is comparatively a low GI value.
Roasted:
Roasted sweet potatoes have a very high GI value of 82.
This high value is that the baking process destroys the
starch content in potatoes, which leads to a rise in GI
value.
Baked:
If we bake sweet potatoes for approximately 45 minutes,
it would have the highest GI value of 94.
Fried:
When we compare the Glycemic Index value of the Fried
version of sweet potatoes with the baked and roasted
version, then we will observe that Fried sweet potatoes
have comparatively low GI values than others.
14. Water chestnuts
Consuming lesser amounts of Water chestnuts is
beneficial. However, if higher amounts of water
chestnuts are eaten, it may cause fluctuations in the
body’s blood sugar levels.
If eaten in higher amounts, then blood sugar levels may
get high and lead to weight gain.
Water chestnuts are very beneficial in limited
quantities and have many health benefits too.
Some
benefits of water chestnuts include:
Lowers blood pressure
Act as antioxidants
Prevents cancer
