Various foods have been labeled alternately good or bad in the press depending on the latest study, resulting in total consumer confusion. Controversy over salt, sugar, eggs, starches and dietary fat are discussed. Moderation and common sense is advised in all cases.

Sugar and salt were wrongly accused of causing everything from diabetes and hypertension to criminal behavior and hyperactivity. Then margarine went from being the cure for high cholesterol to one of its causes. Fats were the villain of the ’90s — but this year, when pasta and other starches are being blamed for weight gain in America, the confused consumer is asking, “What’s left to eat?” It’s no wonder that so many of us have become nutrition skeptics Where do we go from here? And just what should we be eating? Well, first, let’s talk about some of these controversial” foods.

A Spoonful of Sugar

Mary Poppins was on target when she sang about a spoonful of sugar helping the medicine go down; recent studies support the theory that sugar becomes a pacifier during painful infant procedures. Researchers now suggest that sugar, once blamed for causing hyperactivity in children, actually produces the opposite calming effect.

Sugar does not cause diabetes and avoiding sugar does not cure it. Revised nutrition guidelines issued last spring by the American Diabetes Association encouraged an individualized approach and stated that blood sugar levels are affected by the total amount of carbohydrate in the diet, regardless of its source. After years of prohibition, people with diabetes are now permitted to eat sugar in moderation, especially when substituted for other carbohydrates.

Sodium Sense

Most Americans consider salt to be downright dangerous, yet the reality is that only a small percentage of Americans require sodium restriction. While most Americans consume much more salt than the body needs, only those who are sodium-sensitive and/or on special medication need to restrict their diets. Salt does not cause hypertension or heart disease but it may exacerbate an already existing condition in certain individuals. Experts estimate that 20-30% of Americans are predisposed to hypertension and that 1/3 of those are sodium-sensitive. For the remaining 2/3, weight-loss medication and other treatments appear more effective than a low-sodium diet.

The Cholesterol Controversy

EGGS — once declared the equivalent of poison — have landed without breaking. Researchers have discovered an individual variation in response to egg consumption. Additionally, saturated fats raise blood cholesterol more than anything else, including eggs. An excellent source of high-quality inexpensive protein, eggs offer dietary versatility and convenience. Because of their high cholesterol content, eggs were banned in the past from the diets of most Americans. However, this advice seems most appropriate for individuals who have heart disease or confirmed elevations of blood cholesterol.

Focus on Fat

While nutrition trends may come and go, the dictum requiring overall control of dietary fat appears to be “carved in stone.” Actually, rigid restrictions of fat intake (10 – 20% of calories) are unnecessary for most people and may be unhealthy; many nutritionists advise. lowering the current intake of fat from 34% to 30% of calories. For a person who consumes 2000 calories daily, this would translate to approximately 600 calories from fat.

Exploration continues on which type of fat is optimal. At one time, polyunsaturated fats, found in vegetable oils and many margarines, were the darlings of the food industry. More recently, excessive intake of margarine has been discouraged because trans-fatty acids (behaving like saturated fats) are formed during hydrogenation. Although small amounts of margarine may be preferable to butter, olive oil and other monounsaturated-rich fats have moved to center stage. Studies suggest that substituting monounsaturated fats (found in olive oil, avocados, etc.) for saturated fats may lower the bad HDL-cholesterol and protect or raise the good HDL-cholesterol.

The Carbo Craze

The “carbo craze” began in the mid-’80s, when Americans embraced a low-fat diet. Nutrition experts extolled the virtues of unlimited complex carbohydrates as a vehicle for lowering fat intake and losing weight. Yet statistics show that over the past decade, the average American gained eight pounds.

Recent articles blamed pasta and other starches for making Americans fat. While it is unfair to single out these foods, it is important to recognize that no food can be eaten in unlimited amounts without consequences. This recent media blitz emphasized the need to balance carbohydrates with protein and fat, as well as exercise, in order to achieve the perfect health profile.


* Forget the “one-size-fits-all” approach to eating.

Although there are common denominators (such as limiting intake of total fat), there no single approach that works for every American; any dietary plan, commercial or noncommercial, must incorporate individual behavioral and lifestyle changes. It essential that each American “know the umbers” of his or her personal health profile. Registered dietitians are able to help translate these numbers and other physician recommendations into workable lans.

* Forget the “good” food/”bad” food philosophy.

Any favorite food can be incorporated occasionally — even on the most restricted diet. Work on emphasizing variety, balance and moderation of food choices.

* The “Mediterranean Diet” contains lessons for many Americans.

Scientists have observed that people in the Mediterranean region who consume a diet rich in vegetables, grains, fruits, fish, poultry and olive oil experience a lower incidence of heart disease and other medal problems than people in the United States or elsewhere in Europe. While the list of popular foods to avoid grows longer, there are foods associated with potentially positive effects, and most of these foods are found in the Mediterranean.

Maintaining cleanroom walls and floors is critical for overall contamination control and for preserving cleanroom protocol. The cleaning of walls and floors is often overlooked because these surfaces are not immediately adjacent to manufactured product and are assumed to contribute little to product defects. If these surfaces are not maintained, particles and residues can accumulate and can migrate or be transferred to critical areas.

String mops vs. flat mops

Maintenance of cleanroom walls and floors is usually accomplished by mopping to clean the large surface areas involved. Mops have sometimes been described as “large wipers on sticks’ This is not altogether a bad description, since many of the substrate selection criteria and usage techniques developed for wipers can be applied directly to mops.

Fundamentally, there are two types of mops–string mops and flat mops. For optimum contamination control and minimum linting, mop heads for string mops and flat mops should be constructed from laundered knit polyester fabric, a material that minimizes particles, fibers, non-volatile residues and ionic contaminants.

Knit polyester has the further advantage of good liquid absorbency and good abrasion resistance.

A string mop head for cleanroom use consists of a bound assembly of wide, tubular strands of knit polyester fabric. String mops, employed primarily for cleaning floors, are used in conjunction with a wring bucket of cleaning solution and rinse water.

A flat mop head for cleanroom use consists of a flat plastic rectangle to which a conformal, foam pad is affixed and over which a replaceable knit polyester mop cover–also known as a bonnet–is attached.

Flat mops are not used with buckets; cleaning agents are applied to the mop cover with squirt bottles. Multiple mop covers are wetted for later use or pre-packaged, pre-wetted mop covers are employed. (1) Mop covers are changed frequently to ensure that contamination is removed efficiently and effectively. Flat mops are used for cleaning walls and floors.

Occasionally, flat sponge mops are used as is or covered with large polyester knit wiping cloths. This brings with it the risk of contamination from the sponge material, which carries a larger particle, fiber, ion and non-volatile residue burden than polyester knit fabric. The cleaning solutions used with sponge mops will efficiently extract these contaminants and transfer them to walls and ceilings.

How to choose

Floors can be cleaned with either string mops or flat mops. The choice depends upon a number of factors:

Filth level: If the floor is very dirty, then a string mop with cleaning solution may be the quickest, most economical way to pick up most of the contamination. Wallis recommends use of a 16:1 solution of deionized water and a commercial cleaning detergent. (1) This should be followed by string mopping of the floor with pure deionized water to remove residues of the cleaning detergent. Finally, after cleaning the floor with a string mop, the floor should be cleaned again with a flat mop (See the section “How to mop”).

Availability of clean water near the area to be cleaned: If the rinse water in the bucket cannot be changed. frequently and conveniently, then there is a good likelihood that the entire floor will be cleaned with the same bucket of water. This is obviously undesirable for optimum contamination control. Under these circumstances, a flat mop with multiple bonnets is desirable.

Need for disinfection: Aseptic fill areas in pharmaceutical or biotech facilities require disinfection of environmental surfaces during cleaning. This usually calls for application of large volumes of cleaning/disinfecting solution, conveniently applied with a string mop.

String mops are almost never employed on walls. From an ergonomic perspective, string mops can be heavy when wetted with cleaning solutions and are awkward to manipulate when working .on vertical surfaces.

It is difficult to control the amount of cleaning liquid applied to a vertical surface with string mops. Finally, there is a safety issue if aggressive cleaning solutions rain down onto cleaning personnel. For these reasons, flat mops are used almost exclusively for cleaning walls.

How to mop

As with wipers, the most effective way to mop horizontal or vertical surfaces is with linear overlapping strokes, moving from clean or dry areas to dirty or wet areas. (1,2,3) Walls are mopped from the top down because the cleanest area of the wall is assumed to be at the ceiling near the HEPA filters.

Floors are best mopped in small rectangular sections using linear overlapping strokes to minimize recontamination of mopped areas. Doorways or high-traffic areas are likely to be the dirtiest, so they should be mopped last. These areas may need more frequent mopping or special attention to remove visible contamination. Damp mopping is much more effective than dry mopping in removing contamination.

Furthermore, damp mopping reduces the possibility of electrostatic discharge (ESD) events near sensitive devices. Mopping of floors with a string mop presents a unique problem. The typical back-and-forth, “S-shaped” mopping strokes that are most efficient and ergonomically advantageous for cleaning floors unfortunately bring contamination from dirty areas back into clean areas. There is no easy solution to this problem other than to continue with this traditional mopping style with a string mop and wring bucket, then re-mop with a flat mop with linear, overlapping strokes.

How often

American Society of Test and Measurement (ASTM) Standard Practice E2042-99 provides a table of cleaning frequencies for all surfaces in the cleanroom, including walls and floors. (2) As an example, for an ISO Class 5 area, daily damp mopping of floors and walls is recommended.

Water availability and disposal

When using string mops to clean floors, Wallis describes the need to change bucket water frequently, after cleaning every 10 to 15 square feet of floor surface. As many as 50 water changes may be required for one floor, making the task quite onerous. This also raises the issue of the availability of clean water and the disposal of waste cleaning agent and waste rinse water.

Most cleanrooms do not have floor drains to dispose of waste liquids or conveniently-located sinks for the supply of clean rinse water. Consequently, there will be a natural tendency to use the cleaning agent and rinse water far longer than is desirable, and the result will be inadequate cleaning of floors with string mops.

Infrequent changing of the cleaning agent and rinse water will do an effective job of spreading contamination over the entire floor. One solution to this dilemma is to eliminate string mops and buckets entirely and to utilize only flat mops with mop covers. This approach has the advantage that mop covers can be changed quickly, frequently and conveniently, without the need to transport buckets of clean and dirty water back and forth across the cleanroom.

This permits the mopping task to be done faster and results in a cleaner floor. Disposal of a dirty mop cover is much simpler and more convenient than disposal of a bucket of dirty water.

Specific requirements for electronic and regulated industry cleanrooms

Cleanrooms for manufacture of electronic devices–semiconductors, data storage, flat panel displays–are particularly sensitive to particles, so mop heads used for cleaning these environments must incorporate the lowest-particle fabrics such as the laundered, knit polyester fabrics described above.

Cellulosic and foam materials are generally not preferred for these areas. Raised floor systems or perforated floors are often found in these facilities. String mops are unsuitable for such applications because water can drip, through to the sub-floor and set off leak detection devices. Consequently, flat mops with disposable mop covers are preferred for such environments.

Regulated industry cleanrooms, such as those used by the pharmaceutical, biotech and medical device industries, can tolerate a somewhat higher level of particles, but not bacterial entities. Foam or sponge mops are often employed in these areas to apply bactericidal cleaning agents, which are allowed to dry onto floors and walls.

Foam or sponge materials, although they exhibit higher levels of contaminants, have the advantage of holding large amounts of liquid per unit area and, thus, require less frequent re-wetting with the cleaning agent. A key requirement for bacteria-sensitive cleanrooms found in pharmaceutical, biotech and medical device industries is the ability to autoclave consumables such as mops prior to introduction into the cleanroom.

The mop must be constructed from materials that will withstand–perhaps multiple times–the elevated temperature and pressures used in autoclaves.


From disposable products to chemical-free microfiber cloths, retailers’ cleaning product assortments reflect the growing diversity of the cleaning category.
Specialty stores and mass merchants alike are showing more specialty cleaners, chemicals, disposable cleaning systems, and a growing assortment of twist and shout mop, brooms and small wares.
For example, a Target store here showed seven different Michael Graves line mops, retailing from $9.99 to $14.99, as well as Michael Graves brooms. The store also showed brooms and mops by Vileda, o cedar spin mop, Scotch-Brite and Libman. Brooms carried retail prices from $3.99 to $11.99; mops retailed at $7.99 to $11.99. The store had clear signs explaining the different styles of mops, including dust, roller, butterfly, self-wringing and deck; and brooms, including corn and angle styles.
The store also showed a wide array of buckets and caddies, including ones by Michael Graves, Vileda, Rubbermaid and Sterilite, retailing from $1.29 to $7.99.

In small wares, the store showed full assortments from Michael Graves, OXO Soft works, Brawny, Rubbermaid and Scotch-Brite. Small wares retailed from $1.49 to $17.99. Target showed an extensive array of chemicals near the stick goods, including items from Method, as well as wipes, Swiffer products and Mr. Clean Magic Reach cleaner.
At a Wal-Mart, the cleaning products were near the chemicals, although many of the small wares were separated from the stick goods. Wipes and disposable products, including the Swiffer Sweep + Vac, Swiffer dusters, the Clorox Toilet Wand and Pledge Grab-it wipes, were displayed in the aisle with stick goods.
Wal-Mart’s assortment was mixed — literally. Brooms and mops held alternating spots on the aisle. In all, there were seven brooms and spin mop reviews, retailing from $3.99 to $9.99. Brands included O’Cedar, Vileda and Wal-Mart’s brand, Mainstays. The store also showed use-specific cleaners, such as the Range Kleen appliance brush, small wares and gloves in the department.
A review of three specialty stores here — Bed Bath & Beyond, Linens ‘n Things and The Container Store — showcased differences in their cleaning departments.
Bed Bath & Beyond’s department, surveyed in a just-opened store, was near the front of the store and included a wide array of chemicals, from OXI Clean, Hagerty, Orange Glo, Kaboom and Bar Keepers Friend. The store also showed a full assortment of stick goods from Casabella, including the Carpet Sweeper and Zoom Broom, and OXO, as well as small wares by OXO, a Glass Wizard, Evriholder’s FURemover broom, EZ Dust It!’s extension pole ostrich-feather duster and Unger’s Total Reach Duster. Stick goods retailed from $6.99 to $34.99.
The store also featured Casabella’s Water Stop Gloves, Star Kitchen’s Heavy Duty Gloves and the Swiffer WetJet.
Linens ‘n Things, meanwhile, showed cleaning products in two locations: by vacuums and in a back hallway near the restrooms. In the floor care department, the store featured an extensive array of chemicals, specialty cleaners and wipes by Method, Gonzo, Oxi-Clean, Simple Green, Orange Glo, Guardsman, Bar Keepers Friend and Hope Co.
Cleaning products included a Bissell cleaning kit with a caddy and cleaners, Casabella’s Terri Mop and Water Stop Gloves, a full assortment of Unger’s extension pole and attachments, EZ Dust It!’s feather and lambs-wool dusters and Evercare’s Sweep ‘N Clean.
Most of the stick goods and small wares, however, were in the back of the store. The assortment included Melody’s sponge and best spin mop; OXO’s broom, mop and sweep set; and Casabella’s mops, sponges and tile scrubber.
The Container Store displayed cleaning products in its laundry-care department. The assortment included the store’s own branded, oversized microfiber dust mop, retailing for $29.99; an array of Casabella mops, brooms, sweep sets and buckets and caddies; and OXO whisk brooms and small wares. In addition, there were several dusters, from a mini duster to a feather duster with an acrylic handle. Small wares included Gonzo’s pet lifter and Casabella’s chamois sponge. The store also showed an extensive array of chemicals by Mrs. Meyer’s Clean Day, Casabella’s Water Stop Gloves and sponges.
The Container Store also showed cleaning products in other departments, such as acrylic cleaner near shelving and Hagerty silver polish in the kitchen department.

Make Your Own Stethoscope (Listen to Heart Beats and Whispers)
When you go to the doctor, he or she often uses an instrument to listen to your heart and lungs. This gadget the doctor uses is a binaural stethoscope. (Binaural simply means it works with both ears.) Apparently the first stethoscope was simply 24 sheets of paper rolled up tightly. Rene Laennec was a young French doctor who first used this “paper” stethoscope in 1816 to examine a young Mademoiselle for modesty reasons. Before Laennec invented the stethoscope, it was customary to listen to the heart beat by putting an car to the patient’s chest. Doctor Laennec was so impressed by his simple paper listening device he went on to make others in his home workshop using a wood-turning lathe. Since it was so simple, Laennec first called the listening aid “le cylindre” which simply means “the cylinder.” However, he changed the name to “stethoscope” which came from the Greek words for “I see” and “the chest.” Laennec’s best stethoscope review were monaural since only one ear at a time was used.
The author’s homemade monaural stethoscope is really simple, but I it works really great! It probably works a lot better than Doctor Laennec’s paper stethoscope!

What You Need:
* cardboard tube from a used roll of paper towels

* a piece of aluminum foil
* duct tape
Making It:
Keep an eye on the photos while you follow these steps.
(1) Wrap aluminum foil over one end of a cardboard tube that came from a used roll of paper towels.
(2) Use scissors to neatly cut the ends of the foil so your “stethoscope” looks better.
(3) Wrap duct tape over the ends of the foil as shown. Hint: Make sure the foil is pulled tightly over the tube’s opening.
1. Place a piece of aluminum foil over one end of the cardboard tube from a used roll of paper towels.
2. Use scissors to neatly trim foil.

3. Fasten foil to tube with duct tape.

Make sure foil is pulled tight over opening before you finish taping foil to tube.
Using Your Stethoscope
Press the stethoscope’s open end against the chest of a person, about where you think their heart is. Press your ear against the stethoscope’s foil end. You should clearly hear a heartbeat. If you can’t, try another place on the person’s chest.
Sometimes it is quite important to listen to a person’s breathing, especially if they have asthma or a bad cold. Stethoscope for sales come in handy here too! To hear breathing sounds, place the open end of your stethoscope on the back of the person, preferably near the center of the upper back. When the lungs are clear and not filled with fluid, you should hear very little. However, if there is fluid present, you will likely hear a wheeze either when they inhale or exhale (or both). If wheezing is present, that person should rest, and if a parent thinks it’s wise, have a doctor examine the person.
This stethoscope can also be used to hear even whispering behind closed doors or through a window. However, you should never listen in on conversations unless the persons you are listening to know it and say it is all right.
