Fruits have a high carb count because they contain more sugars than vegetables. Does that mean we should completely ban fruits from our keto diet because they are high in carbs? No. Some fruits have a lower glycemic index and glycemic load because they are high in fiber and have less amount of sugar. Others are high in fat, making them a good choice for the keto diet.

Blueberry fruit is packed with nutrients that can benefit your health. Allow me to answer for you the most important questions on blueberries. How many carbs in 1 cup of blueberries?

Blueberries may contain more carbs in one cup than other berries but are considered keto-friendly. The glycemic index (GI), which is the measure of how quickly foods increase blood sugar, of raw blueberries is 53, which is considered a low GI. The glycemic load, which represents how much foods raise blood sugar levels, is 4. What this means is, if you eat blueberries, they will raise blood sugar levels at a much slower rate, making them a great delicious choice for type 2 diabetes and metabolic syndrome.

I would recommend squeezing in a quarter or one-half a cup of blueberries into your diet when meal planning. Pay close attention to the portion sizes of this fruit, because the more you eat the more net carbs you add to your carb intake.

On keto, fresh blueberries are recommended over dried blueberries since they have fewer carbs. In addition, some dried blueberries contain added sugar, which adds to your total carbs.

Most processed foods have a high sugar content hence not recommended on a low-carb diet. As much as I am advocating for fresh blueberry fruit, my advice is to avoid store-bought blueberry jams and jellies, canned blueberry fillings, and blueberry fillings. These are high in sugar and calories, which could kick you out of ketosis.

Moreover, one serving of blueberries contains 25% of the manganese recommended daily value. Manganese promotes bone health and helps in the metabolism of foods like carbs.

They are also rich in other micronutrients like calcium, zinc, phosphorous, and magnesium that make them a nutritious addition to your diet.

Improve Brain Function

Eating blueberries has been proven to improve mood and memory, and lower rates of cognitive decline. One small study to investigate neural activation with blueberry supplementation in mild cognitive impairment (MCI) showed an enhances neuronal response in blueberry-supplemented older adults with cognitive decline.

Another randomized trial found that eating blueberries had a positive effect on mood and cognitive performance.

This improvement is attributed to its antioxidative properties, whose action in our hippocampus, the part of the brain that controls memory, reduces stress-related changes that can reduce the functioning of our brain cells as we age.

An important antioxidant in blueberries, anthocyanins have gained much interest in improving health and functionality Eating blueberries rich in anthocyanins has been associated with lower risks of heart disease and diabetes and disease-related mortality, neuroprotection, blood sugar regulation, and weight maintenance.

A randomized controlled trial on the effects of consuming blueberries on hypertension reported that daily consumption of blueberries lowers blood pressure and reduces arterial stiffness. This is attributed to the polyphenols in blueberries that increase the production of nitric oxide and reduces angiotensin II-induced oxidative stress and inflammation in endothelial cells of blood vessels.

People with hypertension should eat blueberries to lower blood pressure and alleviate biomarkers of cardiovascular disease.

Reduce Risks of Chronic Disease

Blueberries are rich in flavonoids that have been proven to reduce the risk of developing and the severity of certain cancers. Phytochemicals like flavonoids, anthocyanins, flavonols, and proanthocyanidins reduce the risks of vascular diseases like ischemic stroke, atherosclerosis, and neurodegenerative diseases.

Blueberry fruit components lower inflammation and damage by oxidative stress and regulate gene expression associated with disease pathophysiology.

Lowers Insulin Resistance

Insulin helps regulate blood sugar levels in the body. Blueberries are low in calories and have a low GI and glycemic load so do not easily spike blood sugar. Although blueberries contain carbohydrates, the phytochemicals in them increase insulin sensitivity. Consumption of raw blueberries can improve insulin resistance and lower the risks of diabetes.
