Lemon juice can help to reduce infections

Lemon is the fruit of the tree Citrus limon, containing citric acid. Lemon juice has multiple health benefits.

Its antibacterial properties help fight infection in the throat and get rid of chest congestion, its high levels of potassium can help provide relief from dizziness, nausea, and fever and its vitamin C content not only fights cancer but also help prevent infection by building up the body's defences and boosts immunity by increasing the body’s white blood cell count, antibodies and interferon, which coats cell surfaces to ward off virus and fight infection.

Lemons contain enough vitamin C to prevent or treat scurvy. It may seem acidic, but its nature is alkaline in the body, to fight acidic conditions and remove acid wastes – vital for arthritis.

Lemon is high in vitamin C and bioflavonoids to strengthen veins, blood vessels and capillaries: prevent thickening of arterial walls, bruising and varicose veins; and fight infections.

Early Hypothesis About Urinary Tract Infection

Early Hypothesis About Urinary Tract Infection
There has been much speculation about the mechanism by which cranberry products protect against Urinary Tract Infections.

In the early 1900s, one researcher observed that consumption of 300-600 g of cranberry sauce/d could promote short term changes in urine pH.

It was hypothesized that this acidification prevented bacterial colonization of the urinary tract epithelium.

Although this was the popular theory subsequent studies were unable to demonstrate that urinary pH always acidified post-consumption.

However, because urinary hippuric acid excretion also increased after cranberry consumption, that substance was suggested as being responsible for the protective effects.

By the 1960s, it was determined that cranberry juice altered urine pH for only a short period of time, that the degree of acidification was not sufficient to provide bacteriological or bacteriostatic effects and that neither acidification nor hippuric acid could be the primary mechanisms.

In 1984, the researcher used E. coli isolates form people with UTIs to determine that cranberry juice contains a non-dialyzable material that specifically inhibits the expression of the p-fimbria of bacteria, hence preventing their attachment to and colonization of the urinary tract.

Given the large body of evidence showing that cranberry juice does not modify urine pH and UTI incidence it is surprising that acidification is still mentioned in current news.

Medicinal Uses of Cranberries Juice

Medicinal Uses of Cranberries
Juice Cranberry is a strong diuretic, and the juice is often prescribed as dietary treatment for urinary tract infection, kidney disorders and other conditions where passing of fluids is desirable. Many women suffer from cystitis, an inflammation and injection of the bladder, at some time in their lives, with as many as one in five women estimated to have urinary tract discomfort at least once a year.

Cranberry can be used both as a preventive and as an adjunct treatment for urinary tract infection. Cranberry juice therapy may require drinking a liter of straight cranberry juice daily, which few are willing to do. Fortunately, cranberry capsules are easily swallowed. There are several theories to explain why cranberry is effective for maintaining urinary tract health: cranberry juice may make the urine more acidic, and the bacteria that cause infection are not likely to flourish in an acid environment; cranberries may cause relatively large amounts of the bacteriostatic hippuric acid to be excreted in the urine; component of the cranberry juice may interfere with the ability of bacteria to stick to the lining of the bladder and urethra, and so they are washed away in the urinary stream.

The last interpretation is generally favored today. It appears that the most common bacterium responsible for urinary tract infection, Escherichia coli, produces constituents known as adhesins to anchor to tissues, and that there are anti-adhesins factors in cranberry juice.
