Foods To Avoid That Cause Bad Breath
Did you know that there are specific foods that may lead to bad breath? This is because of volatile sulfur compounds - the culprit in causing bad breath!
For example, if food sits out too long it will spoil. That spoiling action is due to anaerobic bacteria breaking down proteins in that particular food. In milk, the odor of sour milk is caused by relatives of the bugs that create bad breath when they break down proteins in the milk (and basically in all dairy foods). A reaction takes place where 'the bad breath bugs' extract sulfur compounds from the amino acids in these proteins. Specifically, the amino acid Cysteine is converted to Hydrogen Sulfide (which has a rotten egg smell) and Methionine becomes Methyl Mercaptan (which smells like a cross between old socks and garlic). The same analogy applies to meat if it sits out too long.
Everyone knows that onions and garlic will create bad breath. But do you know why? It's because the odorous molecules in onions and garlic are actually sulfur compounds themselves called Mercaptans. Sulfur is nature's way of creating odors. You're all familiar with the skunk. Its odor is created by a defense and/or attack mechanism. Skunk odor is made up of skatoles, which are naturally occurring sulfur compounds. In a similar fashion, bacteria in your mouth creates the volatile sulfur compounds of bad breath and taste disorders.
There are 4 food categories that will result in an increase of
sulfur production because these categories have a stimulating affect
on the bacteria that cause bad breath:
1. Drying Agents
2. Dense Protein Foods
3. Sugars
4. Acidic Foods
Let's look closely at each of these food categories and how
they stimulate bad breath!
DRYING AGENTS
The most common drying agent in food is alcohol. Alcohol of
course, is the basis of all "adult" beverages such as beer, wine,
and hard liquor. It is also used, unfortunately, in many mouthwashes
you find in the grocery stores, which only makes a bad breath problem
worse.
Alcohol, known chemically as a desiccant, is used quite often
in laboratories to "dry out" hard to reach areas in test tubes and
beakers. The same end result takes place in the oral cavity.
Although cigarettes are not really food, smoking is probably
the quickest way to dry out your mouth, with alcohol being the second.
If you smoke, you are bound to have bad breath!
DENSE PROTEIN FOODS
Dairy foods are notorious for creating bad breath. An article
that appeared in the "Los Angeles Times" once noted that over 50%
of the population in Southern California was "lactose intolerant".
With regards to bad breath, many of these people (numbering in the
tens of millions) end up with more dense proteins available as bad
breath fuel for the bacteria than those who have no problem with
dairy foods like milk, cheese, yogurt, ice cream, etc. The end result
is a buildup of amino acids, which are easily converted into volatile
sulfur compounds by the anaerobic bacteria found within the surface
of your tongue and throat.
To a lesser extent, people have the same problem with other
types of food that are considered to be dense in protein such as
beef, chicken, and fish.
Another problem, thankfully rare, has to do with people who
have an inability to break down certain proteins found in beans.
This condition is called TMA (Trimethylaminuria) and is sometimes
known as the "Fish Odor Syndrome," because the odor produced is
similar to decaying fish. The odor consists of sulfur compounds,
plus nitrogen compounds (amines). People with this condition must
abstain from beans and other types of food that are dense in protein.
SUGARS
Wouldn't it be great if we could get rid of bad breath by
chewing on M&Ms? Or what if the cure for bad breath were Hershey
Kisses?
That's what the makers of Altoids would have you believe.
Altoids, and other products of the same ilk, are trying to fool
the public into believing that a strong "good" taste in your mouth
is equivalent to the "freshness" of your breath. This is so anti-scientific
it's absurd! If you think about it for a minute, it really doesn't
make any sense.
By using concentrated mint flavorings, your taste buds pick
up mint as a taste. However, Altoids contains two types of sugar
which again, are a fuel for the bacteria to reproduce and create
more sulfur compounds - thus bad breath. In addition, the frightening
part is that other bacteria can take the sugars and produce glycan
strands, which in turn end up causing thick layers of plaque on
the enamel of your teeth and around your gums. This leads to tooth
decay and gum disease - and you guessed it - worse breath than you
started with!
Since you can't smell your own breath, you just go merrily
along with that great strong mint taste in your mouth, while others
close to you are backing away - backing away from your increased
bad breath, decayed teeth, and gross, swollen, bleeding gums!
Stay away from candies, mints, and chewing gum if they contain
sugar! Instead, let me recommend an alternative created by TheraBreath
called the TheraBreath Oxygenating Chewing Gum (http://www.therabreath.com/products.asp?CAT=5).
It releases Oxygen molecules directly into your mouth and also contains
the antibacterial agent, Zinc Gluconate. This agent is found in
many cold medications. In addition it contains Xylitol, which is
a natural sweetening agent with an anti-decay compound.
ACIDIC FOODS
Foods with a high acidic content are a problem as well. pH
is a term used to describe the acidity of an environment. The oral
cavity has a normal pH of 6.5 (7 is considered neutral). Some of
the foods you should watch out for are coffee and many citrus juices.
Both decaffeinated and regular coffee contain acids. However, tea
is okay. Among the citrus juices the ones with the highest acidic
content include tomato juice, orange juice, pineapple juice, and
grapefruit juice.
We know that acids make the bacteria reproduce much faster.
In order to decrease the production of odorous sulfur compounds,
the acid environment needs to be neutralized.
What can you learn from all this? Avoiding foods that contribute
to, if not cause, bad breath is vital if you want to have clean
fresh breath. While this is a difficult task, being aware of these
bad breath causing elements is the first step in developing confidence
in your breath. In addition, it is important to use oral care products
that are free of alcohol, sugar, and that also have a high pH level.
