The Dangers of Aluminum Exposure and 9 Ways To Prevent It
Aluminum is all around us, but it’s when it
builds up in excess in the human body, it can become a health threat.
Unfortunately, scientific evidence shows that most people are still
exposed to too much aluminum, despite the efforts of international
regulations to lower global human aluminum exposure. But how does
aluminum get into our bodies anyway? Scientists say that the culprit
lies in our foods and self-care items, and in this article, we explain
how to avoid it.
How Can Aluminum Affect the Health?
Complete avoidance of aluminum is
impossible, as this metal is one of the most widespread ones on the
planet and it can be found in the soil, water, the food we eat, and even
in the air we breathe. Usually, our body is good at washing out excess
aluminum through urine, but when exposure to the metal rises, some of
the excess aluminum ends up accumulating in the body, which is when it
can become dangerous to human health.
This is why many international regulatory bodies, such as the World
Health Organization and European Food Safety Authority determined a
tolerable weekly aluminum intake of 1 milligram per kilogram (2.2 lbs)
of body weight per week. So, for example, if you weight 65 kg (143 lbs),
your intake of aluminum should not exceed 65 mg a week.
Although there is too little evidence regarding the effects of excessive
aluminum intake on human health, studies have linked it to the
following conditions:
Neurotoxicity, adverse effects on the nervous system.
Alzheimer's disease, with unusually high levels of aluminum found in
Alzheimer's patients' brains.
IBD, but only in animal models and in vitro studies.
Breast cancer.
In a recent large scale study conducted in Germany, researchers found
that people typically consume twice the amount of aluminum they should
be from food and cosmetics alone, so we thought it might be useful to
learn about the ways you can lower your aluminum intake and prevent the
development of any potential adverse reactions.
Here are 9 ways that will help you significantly lower your weekly
aluminum intake:
1. Cosmetic and Self Care Products
Look at the ingredients in your cosmetic products, especially toothpaste
and antiperspirants, as these two categories of products often contain
aluminum. In antiperspirants, aluminum is used as an agent that can
prevent you from sweating by blocking your pores, but it may be absorbed
into your body as well.
The same German study we mentioned earlier even suggested that
antiperspirants containing aluminum alone may exceed the recommended
weekly exposure to the metal.
On a slightly different note, certain medications, such as antacids, for
example, can contain high levels of aluminum, but usually, the benefits
of these medications outweigh their risks, so we wouldn't recommend
avoiding them, especially if they were prescribed to you by a doctor.
2. Cooking Utensils 
Avoid cooking and storing food in uncoated aluminum pots or aluminum
foil, as aluminum particles can seep into your food, and then travel
into your body. This is particularly true when it comes to highly acidic
foods, such as tomato sauces, soups, etc., as well as salty foods, as
both salt and plant-derived acids will eat through the foil and utensils
faster and aluminum particles will travel into the food.

faster and aluminum particles will travel into the food. 3. Drinking-Water
As previously mentioned, water can be another source of aluminum
exposure, with some areas containing higher levels of aluminum in the
soil and water than others. If you know that the water in your area
contains high quantities of aluminum, you'll be better off investing in
some type of water purification system, i.e. water filters, to protect
yourself from the dangers of excessive exposure.
4. Takeaway Boxes
Metal takeaway boxes are so popular, but the thing is that all of them
are made of aluminum, so they're not the best way to store food, being
pretty much equal to using aluminum foil to wrap up your foods. Try to
avoid these boxes and opt for paper takeaway boxes. These are not only
biodegradable and kinder to the planet, but they're also better for your
health than aluminum or plastic ones.
5. Store-Bought Foods
Buying food in supermarkets is tricky, as
you will never know how the food was prepared, what kind of water was
used to make the product, and how it was stored. To minimize your
aluminum exposure from store-bought products, your best bet is NOT to
stick to one brand. Even if some of the foods you buy will contain
aluminum, by switching them up with those that potentially don't contain
it will help you lower your overall exposure to the metal.
6. Fruit and Vegetables
Most fruit and vegetables will have some
aluminum in them naturally, but farmers also add pesticides containing
aluminum when they grow plant produce, so make sure to wash all the
fruit and veggies you buy thoroughly before adding them to dishes or
eating. Apart from that, certain foods, such as spinach, tea leaves,
mushrooms, and radishes tend to absorb more aluminum than others, so
it's best to either purchase these organic or consume them in
moderation.
7. Aluminum Foil and Single-Use Aluminum Baking Pans
Heat is another factor that will cause
aluminum particles to seep into your foods, so using aluminum foil or
those single-use aluminum tins that are so often used in baking is not
the greatest idea if you're planning on minimizing your aluminum intake.
This doesn't mean that you have to forget about grilling meat or
vegetables in aluminum foil forever, but do be mindful of the tools you
use when you're cooking and don't abuse aluminum cooking equipment.
8. Processed Foods
Another reason why you should stay away
from store-bought snacks and processed, packaged foods is because of the
chemicals they use to make food last longer and look better. Aluminum
is routinely used in food coloring, thickeners and anti-caking
ingredients in commercially produced foods. For this reason, get in the
habit of preparing homemade snacks and desserts, such as cookies, as
commercial products have been suggested in studies to contain more
aluminum than homemade foods due to these additives.
9. No Need to Be Afraid of Canned Foods and Drinks
There are plenty of reasons to avoid canned
soft drinks, but aluminum exposure is not one of them. There was a
study conducted on the quantity of aluminum in canned drinks, and it
found that even after 12 months of storage, the concentration of
aluminum in the drink was negligible compared to the exposure we get
from foods.
Needless to say, we're not urging you to start consuming canned sugary
drinks. Instead, we'd just like to say that consuming foods and drinks
that come in aluminum cans is safe for your health in terms of their
risks of aluminum exposure.
