What is Concentrated Lemon Juice?

Concentrated lemon juice, just like normal lemon juice, is extracted from the fruit. In concentrated lemon juice, their content is evaporated after extracting it from the real fruit, and subsequently, it is dried up to make a powder.

Lemon Juice vs Concentrated Lemon Juice – The Effects On Health

Both lemon juice and concentrated lemon juice were derived from the lemon. This shows that they are both beneficial to health. However, lemon juice has been found to be more beneficial than lemon juice concentrate.

Concentrated lemon juice, just like other fruit concentrates, contains beneficial plant compounds like carotenoids, anthocyanins, and flavonoids. These plant compounds have many health benefits as they may contribute to improving heart health and decreasing inflammation.

Lemon juice concentrates might help in skin health as it contains vitamin C and other antioxidants, which will help slow the effects of skin aging.

However, concentrated lemon juice may have some potential downsides to health because some products are loaded with sugars and additives. This means that you have to carefully check the ingredients used in making the juice concentrates before buying.

However, both lemon juice and lemon juice concentrate lack fiber that the fruit provides. If you are buying either the juice or the juice concentrate because of the fiber content, then you are better off eating the fruit.

What Does The Research Say?

Different research conducted points towards the positive. It has been shown that lemon juice helps to significantly reduce blood sugar.

Lemon juice also contains flavonoids which help in fighting cancer. Some contents in lemon juice also help in fighting infections.

Concentrated lemon juice contains beneficial plant compounds which help in increasing heart rate.

Diabetes and Lemon Juice – The Effect On Blood Sugar

Due to lemon’s high and beneficial nutritional content, it is recommended for both diabetics and non-diabetics.

American Diabetics Association has listed lemon as a superfood, and this is largely due to the soluble fiber and high amount of vitamins. Lemon juice lacks fiber but contains all the other important nutrients found in lemon.

Both lemon juice and the lemon fruit itself have a low glycemic index. Any meal with a low glycemic index helps lower blood sugar and insulin levels.

This means that lemon juice having a low glycemic index might help to lower blood sugar. However, lemon juice lacks fiber, so it might not be very effective in reducing blood sugar when compared to fruit.

Is Lemon Juice Good For Diabetics?

Lemon juices have a high content of giber, vitamin C, and potassium, which greatly benefits diabetics. All these important nutritional content tremendously help to improve the health of diabetics.

Lemon juice is good for people with diabetes because of the following reasons.

  • The fibers in lemon can help control and reduce the risk of heart disease

The role of fiber in the health of diabetics can’t be overemphasized.

Fiber intake is important for people with diabetes because of the increased risk of cardiovascular diseases. Fiber functions to increase glycemic control, reduce insulin requirements, reduce triglyceride levels and also help in weight loss.

There are also chances of high fiber food improving metabolic control for diabetics, and also lowering blood pressure.

Due to the fact that fibre-rich food lowers glycemic index, it prevents excessive fluctuation of blood glucose levels, thereby keeping you full for a long period.

However, lemon juice contains virtually no fiber but is contains other vital nutrients. So whether you take the lemon or the juice, you will still get good nutrients which will improve your health as a person with diabetes.

  • The vitamin c content helps to reduce blood glucose

It is no longer a hidden fact that vitamin C is very much necessary for people with diabetes.

It has also been discovered that there is an inverse relationship between vitamin C and the risk or chances of diabetes.

Some researchers found that intake of fruits and vegetables significantly reduced the risk or chances of developing diabetes.

Lemon is a fruit with a high vitamin C content and gives you nearly 50% of the daily value of the vitamin.

Vitamin C can be obtained from different sources. Some combine vitamin C with medicines like metformin to treat diabetes. The research carried out found that people with diabetes who took oral vitamin C with metformin experienced a reduction in levels of fasting and post-meal blood glucose and glycosylated hemoglobin.

However, even though you can still get vitamin C through supplementation, there are chances of side effects that can also prove harmful. That is why choosing natural sources of vitamin C like lemon juice is highly recommended above other sources.

  • The potassium content of lemon juice helps to reduce heart problems

Artherioscosis is a very common condition amongst people with diabetes. Arteriosclerosis is caused due to hardening of arteries which occurs as a result of calcium buildup.

Potassium helps to reduce the hardening of arteries. By reducing the hardening of arteries, potassium helps to lower blood pressure and reduce the risk of strokes and heart attacks.

Potassium will also help in balancing the effect of high sodium diet. Therefore, incorporating lemon juice in your diet will give you all the benefits of potassium without any risk of side effects.

  • Lemon juice and lemon water has been recommended for digestion

There is a need to have a functional digestive system both for diabetics and non-diabetics. Any obstruction to the digestive system can pose a very big health challenge.

A digestive system that is not functioning well can lead to acid reflux, or gastroparesis. Gastroparesis causes slow digestion of food and slow emptying of food. Some medications are available to treat these problems. However, lemon water helps to aid the digestion of food and improves the general function of the digestive system. It is much more recommended and preferable to other medications available because it is purely natural with minimal or no side effects.

Starting your day with lemon juice or lemon water serves a whole lot of benefits. This will help stimulate muscular contractions, which will help purge your system of toxins that must have been accumulated.

If the digestive problem is due to being overweight, lemon juice can help you burn calories and improve your digestion.

  • Lemon juice has a low-calorie ingredient which helps it meets up nutrient needs.

People with diabetes usually struggle to find the most suitable meal that has low sugar, carbs, or calories. Lemon is very suitable as it contains low fats and calories.

You can use lemon for salad dressing as a substitute for sugar-based mayonnaise.

Diabetes And Concentrated Lemon Juice – The Effect On Blood Sugar

The whole lemon family has a low glycemic index, and can then be said to lower sugar. However, this is only sure and proven for lemon fruit.

Although concentrated lemon juice might have a low glycemic index, it lacks fiber. This means that there are chances of the concentrate causing a spike in blood sugar.

Fiber generally helps to stabilize blood sugar level, so any meal, fruit or juice lacking fiber may be at risk of causing a sugar spike. So, until a substantial research report is done, it might be better off to stay away from lemon juice concentrates, or other juice concentrates. If otherwise stated by your health care professional and there is a need to take a juice concentrate, then you can go ahead, but otherwise, avoid it and opt for the fruit as much as possible.

Is Concentrated Lemon Juice Good For Diabetics?

Concentrated lemon juice, no doubts, contains some important nutrients which may be good for people with diabetes.

It might not hurt to take a small portion of concentrated lemon juice as a person with diabetes. However, it is important to note that some lemon juice concentrates might harbor sugar, additives and unhealthy preservatives, just like other juice concentrates.

If you are to take juice concentrates, then you should get the ones with little or no sugar. This is because sugar is bad for people with diabetes.

However, when taking any processed lemon fruit, juices or food, it is always advisable to tread with caution. This is very much advised when you are taking an already processed lemon juice or lemon juice concentrate. Some producers might decide to add one or two preservatives or additives for the longer-lasting of the product.

If you have a way of making your own lemon juice at home, you can go for that option; if not, you can go for processed fruits as the last resort.
