IS IT SAFE TO COOK WITH ALUMINUM FOIL?

Aluminum foil is a common household product that’s often used in cooking.
Some claim that using aluminum foil in cooking can cause aluminum to seep into your food and put your health at risk.
However, others say it’s entirely safe to use.
This article explores the risks associated with using aluminum foil and determines whether or not it is acceptable for everyday use.

What Is Aluminum Foil?

Aluminum foil, or tin foil, is a paper-thin, shiny sheet of aluminum metal. It’s made by rolling large slabs of aluminum until they are less than 0.2 mm thick.
It’s used industrially for a variety of purposes, including packing, insulation and transportation. It’s also widely available in grocery stores for household use.
At home, people use aluminum foil for food storage, to cover baking surfaces and to wrap foods, such as meats, to prevent them from losing moisture while cooking.
People may also use aluminum foil to wrap and protect more delicate foods, like vegetables, when grilling them.
Lastly, it can be used to line grill trays to keep things tidy and for scrubbing pans or grill grates to remove stubborn stains and residue.

There Are Small Amounts of Aluminum in Food

Aluminum is one of the most abundant metals on earth.
In its natural state, it is bound to other elements like phosphate and sulfate in soil, rocks and clay.
However, it’s also found in small amounts in the air, water and in your food.
In fact, it’s naturally occurring in most foods, including fruits, vegetables, meats, fish, grains and dairy products.
Some foods, such as tea leaves, mushrooms, spinach and radishes, are also more likely to absorb and accumulate aluminum than other foods.
Additionally, some of the aluminum you eat comes from processed food additives, such as preservatives, coloring agents, anti-caking agents and thickeners.
Note that commercially produced foods containing food additives may contain more aluminum than home-cooked foods.
The actual amount of aluminum present in the food you eat depends largely on the following factors:
  • Absorption: How readily a food absorbs and holds on to aluminum.
  • Soil: The aluminum content of the soil the food was grown in.
  • Packaging: If the food has been packaged and stored in aluminum packaging.
  • Additives: Whether the food has had certain additives added during processing.
Aluminum is also ingested through medications that have a high aluminum content, like antacids.
Regardless, the aluminum content of food and medication isn’t considered to be a problem, as only a tiny amount of the aluminum you ingest is actually absorbed.
The rest is passed in your feces. Furthermore, in healthy people, absorbed aluminum is later excreted in your urine.

Cooking With Aluminum Foil May Increase the Aluminum Content of Foods

Most of your aluminum intake comes from food.
However, studies show that aluminum foil, cooking utensils and containers can leach aluminum into your food.
This means that cooking with aluminum foil may increase the aluminum content of your diet.
The amount of aluminum that passes into your food when cooking with aluminum foil is affected by a number of things, such as:
  • Temperature: Cooking at higher temperatures.
  • Foods: Cooking with acidic foods, such as tomatoes, cabbage and rhubarb.
  • Certain ingredients: Using salts and spices in your cooking.
However, the amount that permeates your food when cooking can vary.
For example, one study found that cooking red meat in aluminum foil could increase its aluminum content by between 89% and 378%
Such studies have caused concern that the regular use of aluminum foil in cooking could be harmful to your health.

Potential Health Risks of Too Much Aluminum

The day-to-day exposure to aluminum that you have through your food and cooking is considered safe.
This is because healthy people can efficiently excrete the small amounts of aluminum the body absorbs.
Nevertheless, dietary aluminum has been suggested as a potential factor in the development of Alzheimer’s disease.
Alzheimer’s disease is a neurological condition caused by a loss of brain cells. People with the condition experience memory loss and a reduction in brain function.
The cause of Alzheimer’s is unknown, but it is thought to be due to a combination of genetic and environmental factors, which can damage the brain over time.
High levels of aluminum have been found in the brains of people with Alzheimer’s.
However, as there is no link between people with a high intake of aluminum due to medications, such as antacids, and Alzheimer’s, it’s unclear if dietary aluminum is truly a cause of the disease.
It is possible that exposure to very high levels of dietary aluminum may contribute to the development of brain diseases like Alzheimer’s.
But the exact role aluminum plays in the development and progression of Alzheimer’s, if any, is yet to be determined.
In addition to its potential role in brain disease, a handful of studies have suggested that dietary aluminum could be an environmental risk factor for inflammatory bowel disease (IBD).

How to Minimize Your Exposure to Aluminum When Cooking

It’s impossible to completely remove aluminum from your diet, but you can work to minimize it.
The World Health Organization (WHO) and Food and Drug Administration (FDA) have agreed that levels below 2 mg per 2.2 pounds (1 kg) body weight per week are unlikely to cause health problems.
However, it’s assumed that most people consume much less than this. 
Here are some steps you can take to minimize unnecessary exposure to aluminum when cooking:
  • Avoid high-heat cooking: Cook your foods at lower temperatures when possible.
  • Use less aluminum foil: Reduce your use of aluminum foil for cooking, especially if cooking with acidic foods, like tomatoes or lemons.
  • Use non-aluminum utensils: Use non-aluminum utensils to cook your food, such as glass or porcelain dishes and utensils.
Additionally, as commercially processed foods can be packaged in aluminum or contain food additives that contain it, they may have higher levels of aluminum than their homemade equivalents.
Thus, eating mostly home-cooked foods and reducing your intake of commercially processed foods may help to reduce your aluminum intake.

HOW SUGAR CAUSES CAVITIES AND DESTROYS THE TEETH

It’s common knowledge that sugar is bad for your teeth, but it wasn’t always so.
In fact, when the ancient Greek philosopher Aristotle first observed that sweet foods like soft figs caused tooth decay, nobody believed him.
But as science has progressed, one thing is certain — sugar causes tooth decay.
That said, sugar on its own is not the culprit. Rather, the chain of events that takes place afterward is to blame.

Your Mouth Is a Battleground

Many different types of bacteria live in your mouth. Some are beneficial to your dental health, but others are harmful.
For example, studies have shown that a select group of harmful bacteria produce acid in your mouth whenever they encounter and digest sugar.
These acids remove minerals from the tooth enamel, which is the shiny, protective, outer layer of your tooth. This process is called demineralization.
The good news is that your saliva helps to constantly reverse this damage in a natural process called remineralization.
The minerals in your saliva, such as calcium and phosphate, in addition to fluoride from toothpaste and water, help the enamel repair itself by replacing minerals lost during an “acid attack.” This helps strengthen your teeth.
However, the repeated cycle of acid attacks causes mineral loss in the enamel. Over time, this weakens and destroys the enamel, forming a cavity.
Simply put, a cavity is a hole in the tooth caused by tooth decay. It’s the result of harmful bacteria digesting the sugar in foods and producing acids.
If left untreated, the cavity can spread into the deeper layers of the tooth, causing pain and possible tooth loss.
The signs of tooth decay include a toothache, pain when chewing and sensitivity to sweet, hot or cold foods and drinks.

Sugar Attracts Bad Bacteria and Lowers Your Mouth’s pH

Sugar is like a magnet for bad bacteria.
The two destructive bacteria found in the mouth are Streptococcus mutans and Streptococcus sorbrinus.
Both of them feed on the sugar you eat and form dental plaque, which is a sticky, colorless film that forms on the surface of the teeth.
If the plaque is not washed away by saliva or brushing, the bacteria convert it to acid. This creates an acidic environment inside the mouth.
The pH scale measures how acidic or basic a solution is, with 7 being neutral.
When the pH of plaque drops below normal, or less than 5.5, these acids start to dissolve minerals and destroy the tooth’s enamel.
In the process, small holes will form. Over time, they will become larger, until one large hole or cavity appears.

Dietary Habits That Cause Tooth Decay

In recent years, researchers have found that certain food habits matter when it comes to the formation of cavities.

Consuming High-Sugar Snacks

Think before you reach for that sugary snack. Many studies have found that the frequent consumption of sweets and sugary drinks leads to cavities.
Frequent snacking on foods high in sugar increases the amount of time your teeth are exposed to the dissolving effects of various acids, causing tooth decay.
One recent study among school children found that those who snacked on cookies and potato chips were four times more likely to develop cavities than children who did not.

Drinking Sugary and Acidic Beverages

The most common source of liquid sugar is sugary soft drinks, sports drinks, energy drinks and juices
In addition to sugar, these drinks have high levels of acids that can cause tooth decay.
Drinking a sugary drink more than twice daily nearly triples your risk of losing more than six teeth.
Fortunately, one study found that reducing your sugar intake to less than 10% of daily calories decreases your risk of tooth decay.

Sipping on Sugary Beverages

If you constantly sip sugary drinks throughout the day, it’s time to rethink that habit.
Research has shown that the way you drink your beverages affects your risk of developing cavities.
One study showed that holding sugar-sweetened beverages in your mouth for a prolonged time or constantly sipping on them increased the risk of cavities.
The reason is because this exposes your teeth to sugar for a longer time, giving the harmful bacteria more opportunity to do their damage.

Eating Sticky Foods

“Sticky foods” are those that provide long-lasting sources of sugar, such hard candies, breath mints and lollipops. These are also linked to tooth decay.
Because you retain these foods in your mouth for longer, their sugars are gradually released. This gives the harmful bacteria in your mouth plenty of time to digest the sugar and produce more acid.
The end result is prolonged periods of demineralization and shortened periods of remineralization.
Even processed, starchy foods such as potato chips, and flavored crackers may linger in your mouth and cause cavities.

Tips to Fight Tooth Decay

Research has found that other factors can hasten or slow the development of cavities, as well. These include saliva, eating habits, exposure to fluoride, oral hygiene and overall diet.
Below are some ways you can fight tooth decay.

Watch What You Eat and Drink


Make sure to eat a balanced diet rich in whole grains, fresh fruits, vegetables and dairy products.
If you do eat sugary foods and sweetened or acidic beverages, have them with your meals, instead of between them.
Also, consider using a straw when drinking sugary and acidic beverages. This will give your teeth less exposure to the sugar and acid in the drinks.
Furthermore, add raw fruit or vegetables to your meals to increase the flow of saliva in your mouth.
Finally, do not allow infants to sleep with bottles containing sweetened liquids, fruit juices or formula milk.

Cut Down on Sugar

Sugary and sticky foods should only be eaten occasionally.
If you do indulge in sweet treats, drink some water — preferably tap water that contains fluoride — to help rinse out your mouth and dilute the sugar that sticks to the tooth surface.
Moreover, only drink soft drinks in moderation, if at all.
If you do drink them, don’t sip them slowly over a long period of time. This exposes your teeth to sugar and acid attacks for longer.
Instead, drink water. It contains no acid, sugar or calories 

Practice Good Oral Hygiene


Not surprisingly, there’s also oral hygiene.
Brushing at least twice per day is an important step in preventing cavities and tooth decay.
It’s recommended to brush after each meal whenever possible and then again before you go to bed.
You can further promote good oral hygiene by using a toothpaste that contains fluoride, which helps protect your teeth.
Additionally, stimulating saliva flow helps bathe the teeth in beneficial minerals.
Chewing sugar-free gum may also prevent plaque build-up by stimulating saliva production and remineralization.
Lastly, nothing ensures keeping your teeth and gums healthy like visiting your dentist every six months.
