What are the 5 worst foods for blood sugar

5 Worst Veggies For Erratic Blood Sugar (And The Five BEST To Add To Your Diet)

Navigating the world of nutrition is like setting sail on a vast ocean with a compass but no map. Every new study is a beacon of hope or a sirens call, and every new fad diet a gust threatening to topple you. For those with diabetes or anyone keenly monitoring their blood sugar levels, the waters are even more treacherous. While vegetables are generally considered a cornerstone of a healthy diet, not all veggies play nice with your blood sugar.

In this article, well sort through the leafy greens and root vegetables to find the ones that may surprise you as the five worst veggies for those with erratic blood sugar, and well finish off with the five BEST veggies for diabetics as an extra bonus. Understanding how these vegetables can impact your blood sugar can help you make more informed choices about what ends up on your plate. But first

Understanding the Glycemic Index (GI)

Before we introduce these five vegetables, its important to understand what the glycemic index is and its significance for those managing diabetes. The GI measures how quickly a carbohydrate-containing food raises blood sugar levels. Foods are ranked on a scale of 0 to 100. The higher the number, the greater the blood sugar spike. Low-GI foods (those below 55) are digested more slowly, causing a gradual rise in blood sugar levels, which is safer for diabetics.

The Importance of Low-GI Foods

For diabetics, consuming low-GI foods is crucial as they help keep blood glucose levels in check. This can reduce the risk of heart disease, improve the bodys sensitivity to insulin, and aid in weight management. Vegetables are excellent sources of low-GI foods, and certain ones are particularly beneficial for those with diabetes. Below are the top 5 veggies with a very high glycemic index that can cause erratic blood sugar.

1) Beets: The Double-Edged Root

Beets are vibrant, earthy, and delicious, cooked or raw. But their natural sweetness hints at their glycemic impact. Beets have a high glycemic index (GI), which means they can cause a rapid spike in blood sugar levels. For those with diabetes or struggling with blood sugar control, beets can be a tricky veggie to manage. However, the complexity doesnt end there. Beets are also rich in nitrates, which have been linked to improved blood flow and heart health. The key here is moderation and pairing beets with foods that have a lower GI to help mitigate their effects.

2) Parsnips: The Surprisingly Sweet Sibling of Carrots

Parsnips are often overlooked in the produce aisle but are a staple in many classic dishes. When roasted, their caramelized sweetness rivals that of sweet potatoes. However, this makes parsnips another high-GI vegetable to be cautious of. They contain more starch than carrots, which contributes to their glycemic load. For individuals with diabetes, consuming parsnips is not off-limits, but portion control and pairing with protein and healthy fats can help slow the absorption of glucose.

3) Pumpkin: Not Just for Pie

Pumpkins are packed with nutrients and low in calories, making them an attractive addition to any diet. However, like parsnips, pumpkins have a higher GI than most non-starchy vegetables. This is especially true for canned pumpkin or pumpkin pie filling, which often contains added sugars and other high-GI ingredients. Choosing fresh, whole pumpkin when possible and preparing it in ways that do not add extra sugar can help mitigate its impact on blood sugar levels.

4) Corn: A Grain Disguised as a Veggie

Corn is a staple in many diets, but its important to recognize that it is a starchy vegetable with a high GI. While fresh corn is higher in fiber than many other grains, which can slow digestion and lower its glycemic impact, its still something to be mindful of for those watching their blood sugar. Additionally, much of the corn available in the market is highly processed, removing much of the beneficial fiber and adding to its glycemic impact. Like with pumpkins, enjoying corn on the cob or fresh off the stalk can be a better option than processed corn products.

5) Potatoes: The Staple That Spans Cultures

No list of high-GI vegetables would be complete without the potato. Potatoes, whether white, red, yellow, or purple, all have a high GI. This means they can significantly raise blood sugar levels, although the exact impact can vary based on the variety and preparation method. For those with diabetes, the recommendation is often to eat smaller portions and pair potatoes with proteins and fiber-rich foods to help mitigate the spike in blood sugar. Foods like whole grain options, lean meats, and vegetables can all be good companions to your potatoes.

NowHere Are The 5 Best Veggies Every Diabetic Should Add to Their Plate

1) Leafy Greens: Spinach, Kale, and Chard

Leafy greens are champions in the world of vegetables for diabetics. They are extremely low in calories and carbohydrates, making them an excellent choice for those looking to manage their weight and blood sugar levels.

17 Foods to Lower Your Blood Sugar

Several foods may help lower your blood sugar, but some may be more effective than others.

Although factors such as body weight, activity, stress, and genetics also play a role in regulating blood sugar, following a healthy diet is critical for blood sugar management (1, 2).

While some foods, including those high in added sugar and refined carbs, can contribute to blood sugar fluctuations, others can optimize blood sugar regulation while promoting overall health (3, 4).

Here are 17 foods that may help regulate your blood sugar.

Sulforaphane is a type of isothiocyanate that has blood sugar-reducing properties. This plant chemical is produced through an enzyme reaction when broccoli is chopped or chewed (5).

Test-tube, animal, and a few human studies have shown that sulforaphane-rich broccoli extract has potent antidiabetic effects, helping enhance insulin sensitivity and reduce blood sugar and oxidative stress markers (6, 7).

Broccoli sprouts are concentrated sources of glucosinolates such as glucoraphanin. Research suggests that these compounds help promote insulin sensitivity and reduce blood sugar levels in people with type 2 diabetes when supplemented as a powder or extract (8, 9).

Additionally, eating cruciferous vegetables may reduce the risk of type 2 diabetes, but more research is needed (10, 11).

The best way to enhance the availability of sulforaphane is to enjoy broccoli and sprouts raw or lightly steamed or add active sources of myrosinase, such as mustard seed powder, to cooked broccoli (12).

Seafood, including fish and shellfish, is a valuable source of protein, healthy fats, vitamins, minerals, and antioxidants that may help regulate blood sugar levels.

Protein is essential for blood sugar management. It helps slow digestion, prevents postmeal blood sugar spikes, and increases feelings of fullness. Plus, it may help prevent overeating and promote excess body fat loss, two essential effects for healthy blood sugar levels (13).

A high intake of fatty fish such as salmon and sardines has been shown to help improve blood sugar regulation.

For example, in a small study with 68 participants, adults with overweight or obesity who consumed 26 ounces (oz), or 750 grams (g), of fatty fish per week had significant improvements in postmeal blood sugar levels compared with those who consumed lean fish (14).

Brightly colored and packed with fiber and antioxidants, pumpkin is a great choice for blood sugar regulation. Pumpkin is a traditional diabetes remedy in many countries, including Mexico and Iran (15).

Pumpkin is high in carbs called polysaccharides, which have been studied for their blood sugar-regulating potential. Treatments with pumpkin extracts and powders have been shown to significantly decrease blood sugar levels in both limited human studies and animal studies (16, 17).

However, more research is needed to determine how whole pumpkins may benefit blood sugar.

Pumpkin seeds are packed with healthy fats and protein, which make them an excellent choice for blood sugar management (18, 19).

A small 2018 study with 40 participants found that consuming 2 oz (65 g) of pumpkin seeds reduced postmeal blood sugar by up to 35% compared with a control group (20).

Discover more about Type 2 Diabetes

Research has shown that eating nuts may be an effective way to help regulate blood sugar levels.

In a small study of 25 people with type 2 diabetes, consuming both peanuts and almonds throughout the day as part of a low carb diet reduced fasting and postmeal blood sugar levels (21).

Also, a review found that consuming various types of tree nuts led to reduced fasting blood sugar levels in people with type 2 diabetes. However, the authors noted that the results were not clinically significant and that more research is necessary (22).

Okra is a fruit thats commonly used like a vegetable. Its a rich source of blood sugar-lowering compounds such as polysaccharides and flavonoid antioxidants (23).

Okra seeds may be beneficial as a natural remedy for diabetes due to their potent blood sugar-lowering properties (24).

Rhamnogalacturonan, the main polysaccharide in okra, has been identified as a powerful antidiabetic compound. Plus, okra contains the flavonoids isoquercitrin and quercetin 3-O-gentiobioside, which help reduce blood sugar by inhibiting certain enzymes (25, 26, 27).

Although animal studies suggest that okra has potent antidiabetic properties, human research studies are needed.

Flaxseed is rich in fiber and healthy fats and may help reduce blood sugar levels.

In an 8-week study of 57 people with type 2 diabetes, those who consumed 7 oz (200 g) of 2.5% fat yogurt containing 1 oz (30 g) of flaxseed each day experienced significant reductions in HbA1c a marker of long-term blood sugar regulation compared with those who consumed plain yogurt (28).

Moreover, a review of 25 controlled studies found that eating whole flaxseed led to significant improvements in blood sugar regulation (29).

Beans and lentils are rich in magnesium, fiber, and protein. These nutrients may be able to help lower blood sugar. Theyre particularly high in soluble fiber and resistant starch, which help slow digestion and may improve blood sugar response after meals (30).

For example, a study of 12 women demonstrated that adding black beans or chickpeas to a rice meal significantly reduced postmeal blood sugar levels compared with eating rice alone (30).

Many other studies have shown that eating beans and lentils can benefit blood sugar regulation and possibly help protect against the development of diabetes (31, 32).

Fermented foods such as kimchi and sauerkraut contain health-promoting compounds, including probiotics, minerals, and antioxidants. Research associates these compounds with improved blood sugar and insulin sensitivity (33, 34).

A 2021 review concluded that probiotic foods had a notable effect on blood sugar regulation in people with type 2 diabetes. Researchers noted that these foods had the greatest impact on people whose diabetes was not well managed and those who were not on insulin therapy (35).

However, most studies into the effect of fermented foods on blood sugar regulation involve rodent or cellular investigations. As a result, further controlled human studies are necessary (36).

Eating chia seeds may benefit blood sugar regulation. Some studies link chia seed consumption to reductions in blood sugar levels and improvements in insulin sensitivity.

A 2020 review of 17 animal studies concluded that chia seeds might help improve insulin sensitivity and blood sugar regulation and potentially reduce disease risk, including the risk of diabetes (37).

Also, a study of 15 healthy adults showed that participants who received 1 oz (25 g) of ground chia seeds alongside 2 oz (50 g) of a sugar solution had a 39% reduction in blood sugar levels compared with those who consumed the sugar solution alone (38, 39).

People often describe kale as a superfood and for a good reason. It contains multiple compounds that may help decrease blood sugar levels, including fiber and flavonoid antioxidants.

A study that included 42 Japanese adults demonstrated that consuming either 7 or 14 g of kale-containing foods with a high carb meal significantly decreased postmeal blood sugar levels compared with placebo (40).

Research has shown that the flavonoid antioxidants found in kale, including quercetin and kaempferol, have potent blood sugar-lowering and insulin-sensitizing effects (41).

Numerous studies link berry intake with improved blood sugar regulation. Berries contain fiber, vitamins, minerals, and antioxidants, and all of this makes them an excellent choice for people with blood sugar management issues.

A 2019 study found that eating 2 cups (250 g) of red raspberries with a high carb meal significantly reduced postmeal insulin and blood sugar in adults with prediabetes compared with a control group (42).

In addition to raspberries, studies have shown that strawberries, blueberries, and blackberries may benefit blood sugar management by enhancing insulin sensitivity and improving glucose clearance from the blood (43, 44, 45).

Avocados may offer significant benefits for blood sugar regulation. Theyre rich in healthy fats, fiber, vitamins, and minerals, and adding them to meals may improve blood sugar management.

Numerous studies have found that avocados may help reduce blood sugar levels and protect against the development of metabolic syndrome through fat loss. Metabolic syndrome is a cluster of conditions, including high blood pressure and high blood sugar, that increases chronic disease risk (46, 47, 48).

However, remember that many studies investigating the effects of avocado intake on blood sugar levels were funded by the Hass Avocado Board, which could have influenced aspects of the studies (46, 48).

Including oats and oat bran in your diet may help improve your blood sugar levels due to their high soluble fiber content, which has been shown to have significant blood sugar-reducing properties (49).

An analysis of 16 studies found that oat intake significantly reduced HbA1c and fasting blood sugar levels compared with control meals (50).

Moreover, a small study of 10 people found that drinking 7 oz of water mixed with 1 oz of oat bran before eating white bread significantly reduced postmeal blood sugar compared with drinking plain water (51).

Although citrus fruits contain natural sugar, they are considered low to medium on the glycemic index. Citrus fruits are also good sources of vitamins, minerals, and fiber (52).

Citrus fruits such as oranges and grapefruit are packed with fiber and contain plant compounds such as naringenin, a polyphenol with powerful antidiabetic properties (53).

Eating whole citrus fruits may help improve insulin sensitivity, reduce HbA1c, and protect against diabetes (54, 55, 56, 57).

Kefir and yogurt are fermented dairy products that may help regulate blood sugar.

An 8-week study of 60 people with type 2 diabetes showed that drinking 20 oz (600 milliliters) of kefir, a probiotic-rich yogurt drink, per day significantly reduced fasting blood sugar and HbA1c compared with drinking kefir that did not contain probiotics (58).

Yogurt consumption may also lower the risk of type 2 diabetes. In a 2022 analysis of 42 studies, the authors concluded that each 50 g (1.7 oz) of daily yogurt intake was associated with a 7% decrease in type 2 diabetes risk (59).

Eggs are a concentrated source of protein, healthy fats, vitamins, minerals, and antioxidants. Some studies have linked egg consumption to better blood sugar regulation.

A study of 42 adults with overweight or obesity and either prediabetes or type 2 diabetes showed that eating one large egg per day led to a significant 4.4% reduction in fasting blood sugar and improvements in insulin sensitivity compared with an egg substitute (60).

Whats more, during a 14-year follow-up study of 7,002 Korean adults, frequent egg intake of two to less than four servings per week was associated with a 40% lower risk of diabetes than eating eggs once per week or less. This association was apparent in men but not in women (61).

Apples contain soluble fiber and plant compounds, including quercetin, chlorogenic acid, and gallic acid, which may help reduce blood sugar and protect against diabetes (62, 63).

A study of 18 women found that eating apples 30 minutes before a rice meal significantly reduced postmeal blood sugar compared with eating rice alone (64).

What foods are good for hyperglycemia?

Foods that may help support blood sugar regulation include broccoli, pumpkin seeds, and nuts, among others. These foods may help slow digestion and typically do not raise your blood sugar.

What foods should you avoid for hyperglycemia?

If you have hyperglycemia, you may need to avoid foods that can raise your blood sugar. This can include foods that are high in sugar and refined carbs, such as white bread, bagels, and sweetened dessert items.

What is the fastest way to reduce hyperglycemia?

If you are experiencing hyperglycemia, a doctor or healthcare professional may recommend using fast-acting insulin to lower your blood glucose levels. They may also recommend an appointment with your healthcare team.

You may need to monitor your blood sugar levels regularly. Your healthcare team can help you develop a treatment plan that involves diet changes, exercise, and medication, if needed, to help lower your blood sugar levels (65).

Following a healthy dietary pattern is essential for optimal blood sugar management.

Whether you have prediabetes or diabetes or want to reduce your risk of developing these conditions, including the foods listed above as part of a nutritious diet may help lower your blood sugar levels.

However, keep in mind that your overall dietary intake, as well as factors such as your activity level and body weight, are most important when it comes to optimizing blood sugar regulation and protecting against chronic disease.
