Question: Four pieces of bacon can contain up to how many mg of sodium?
About the article "Bacon", section "Nutrients".

Candidate passages:
One rasher of cooked streaky bacon contains of fat, and of protein.
Four pieces of bacon can also contain up to 800 mg of sodium, which is roughly equivalent to 1.92 grams of salt.
The fat and protein content varies depending on the cut and cooking method.68% of bacon's calories come from fat, almost half of which are saturated.
Each ounce of bacon contains 30 milligrams of cholesterol.
 in food.
Salt is present in most foods, but in naturally occurring foodstuffs such as meats, vegetables and fruit, it is present in very small quantities.
It is often added to processed foods to make their flavour more appealing and is also present at higher levels in preserved foods.
Thus herring contains 67 mg sodium per 100 g, while kipper, its preserved form, contains 990 mg.
Similarly, pork typically contains 63 mg while bacon contains 1480 mg, and potatoes contain 7 mg but potato crisps 800 mg per 100 g. The main sources of salt in the diet, apart from direct use of sodium chloride, are bread and cereal products, meat products and milk and dairy products.
In many East Asian cultures, salt is not traditionally used as a condiment.
In its place, condiments such as soy sauce, fish sauce and oyster sauce tend to have a high sodium content and fill a similar role to table salt in western cultures.
They are most often used for cooking rather than as table condiments. 
Pennsaid is a minimally systemic prescription topical lotion formulation of 1.5% w/w diclofenac sodium, which is approved in the US, Canada and other countries for osteoarthritis of the knee.
Flector Patch, a minimally systemic topical patch formulation of diclofenac, is indicated for acute pain due to minor sprains, strains, and contusions.
The patch has been approved in many other countries outside the US under different brand names.
Voltaren and Voltarol contain the sodium salt of diclofenac.
In the United Kingdom, Voltarol can be supplied with either the sodium salt or the potassium salt, while Cataflam in some other countries is the potassium salt only.
However, Voltarol Emulgel contains it as dichlofenac diethylammonium where 1.16% is equivalent to 1% of the sodium variety.
Diclofenac is available in stomach acid-resistant formulations (25 and 50 mg), fast-disintegrating oral formulations (25 and 50 mg), powder for oral solution (50 mg), slow- and controlled-release forms (75, 100 or 150 mg), suppositories (50 and 100 mg), and injectable forms (50 and 75 mg).
Diclofenac is also available over-the-counter in some countries: 12.5 mg diclofenac as potassium salt in Switzerland (Voltaren dolo), the Netherlands (Voltaren K), United Kingdom (since October 2008 as Voltarol Pain-eze), and preparations containing 25 mg diclofenac as the potassium salt in Germany (various trade names), New Zealand, Australia, Japan, (Voltaren Rapid), and Sweden (Voltaren T and Diclofenac T).
Diclofenac as potassium salt can be found throughout the Middle East in 25-mg and 50-mg doses (Cataflam).
Solaraze (3% diclofenac sodium gel) is topically applied, twice a day for three months, to manage the skin condition known as actinic or solar keratosis.
Parazone-DP is combination of diclofenac potassium and paracetamol, manufactured and supplied by Ozone Pharmaceuticals and Chemicals, Gujarat,India 
Another concern is that if served in an instant broth, instant noodles typically contain high amounts of sodium.
The current U.S.
Recommended Dietary Allowance of sodium for adults and children over 4 years old is 1,500 mg/day.
Typical cup-type instant noodles contain 2700 mg of sodium (per 100 g of edible portions). 
Health effects.
Effects of sodium.
According to the Mayo Clinic, "An 8-ounce (237-milliliter) glass of softened water generally contains less than 12.5 milligrams of sodium, which is well within the Food and Drug Administration's definition of 'very low sodium.'
" Of course, the exact amount of sodium present in soft water will depend upon how much hardness is being removed by the softener (harder water=more sodium ions being exchanged for the hardness ions) as well as the levels of naturally occurring sodium that is present in many groundwater sources.
The CDC recommends limiting daily total sodium intake to 2,300 mg per day, though the average American consumes 3,500 mg per day.
Because the amount of sodium present in drinking water—even after softening—does not represent a significant percentage of a person's daily sodium intake, the EPA considers sodium in drinking water to be unlikely to cause adverse health effects.
For those who are on sodium-restricted diets, the use of a reverse osmosis system for drinking water and cooking water, will remove sodium along with any other impurities which may be present.
Potassium chloride can also be used as a regenerant instead of sodium chloride, although it is more costly.
For people with impaired kidney function, however, elevated potassium levels can lead to complications such as cardiac arrhythmia.
Hard water also conveys some benefits to health by reducing the solubility of potentially toxic metal ions such as lead and copper, which are more soluble in soft water than in hard water.
