Stanley Cups Contain Lead – Should You Be Worried?

It was just revealed that Stanley cups contain lead. Should you be worried or should you keep adding to your Stanley cup collection? Just like the Beanie Baby craze that came before it, the Stanley cup obsession is defying consumer logic. In a race to collect all the Stanley cups, thousands of dollars are being “invested”, people are being assaulted, and stores are being robbed. Check out these videos if you want to get caught up on the Stanley cup saga.

Stanley Cups Contain Lead

Before you start planning a Stanley cup heist that makes the movie Italian Job look like an amateur operation, realize that Stanley cups contain lead. Yes lead, the heavy metal neurotoxin that was placed in gasoline to increase its octane, in paint to reduce flaking, and in water pipes to reduce corrosion.1

In all cases, placing lead in consumer products has been an absolute disaster. Leaded gasoline alone is responsible for collectively reducing the IQ of Americans by 824 million points. Lead toxicity is also linked with a wide range of health problems including reproductive and cardiovascular issues.2 3

Why Do Stanley Cups Contain Lead?

According to Stanley, they use a lead pellet in their production process to aid in the insulation of beverages. They placed a stainless steel covering over the lead to ensure that no lead contamination occurs unless the barrier is removed, which according to them, is possible, but a rare occurrence.4

By the looks of it, they also use the lead as a stabilization weight, to ensure that Stanley cups don’t fall over due to their small, but convenient cup holder-sized bottoms.

Stanley says they are taking steps to find alternative materials for their sealing process and are currently working on implementing these innovations in their manufacturing process.

Symptoms Of Lead Poisoning

Lead poisoning has detrimental effects on both physical and mental health, particularly for children as their bodies are still developing. Lead poisoning can happen gradually with repeated exposure to small amounts of lead, or it can occur suddenly after being exposed to a large amount of lead.

Symptoms of lead poisoning vary depending on the individual and the level of exposure. Lead causes damage to the stomach and intestines, leading to abdominal pain. Lead slows down the digestive system, causing constipation. Lead disrupts the production of red blood cells, resulting in fatigue and weakness.

Lead exposure has been linked to headaches, particularly migraines. Children with lead poisoning may exhibit irritability, mood swings, and decreased attention span. Lead often suppresses the appetite, leading to weight loss and malnutrition.

Lead poisoning in children causes damage to blood vessels and increases their risk of developing hypertension at an early age. This has long-term consequences on their health as they grow older.

Lead affects brain function, leading to memory loss and difficulty concentrating. High levels of lead damages nerves, causing numbness or tingling in the hands and feet. In severe cases of lead poisoning, seizures may occur.

If left untreated, lead poisoning leads to serious complications such as kidney damage, nerve damage, anemia, and even death. This is why it’s crucial to identify and treat lead poisoning as early as possible.5

Lead Poisoning And Autoimmune Conditions

Lead poisoning has been linked to the development of autoimmune conditions. An autoimmune condition is a disorder in which the immune system attacks healthy cells and tissues in the body, causing inflammation and damage.

Lead disrupts the normal function of the immune system, making it more likely to attack the body’s own cells. Studies have shown that individuals with higher levels of lead in their blood are more likely to have certain autoimmune conditions such as rheumatoid arthritis.6

It is also important to note that lead poisoning may trigger or worsen existing autoimmune conditions. This is because lead exposure causes chronic inflammation and oxidative stress, which are known triggers for autoimmune responses.7

Lead Poisoning And Cardiovascular Diseases

Lead damages blood vessels by increasing oxidative stress and inflammation, leading to atherosclerosis, which is a major risk factor for heart disease. Lead has also been found to disrupt the production and function of red blood cells, leading to anemia. Anemia reduces oxygen levels in the blood, putting extra strain on the heart.

In addition, lead also alters the function of the autonomic nervous system, which regulates heart rate and blood pressure. This contributes to hypertension, a major risk factor for cardiovascular diseases, and it often leads to heart attacks, strokes, and other serious complications.8

Moreover, lead exposure during pregnancy has detrimental effects on the developing cardiovascular system of the fetus. Studies have shown that mothers with high levels of lead in their blood are more likely to have children with congenital heart defects.9

Lead Poisoning And Endocrine Conditions

Research has shown that exposure to lead disrupts the proper functioning of the endocrine system. Lead acts as an endocrine disruptor, meaning it interferes with hormone production and regulation. This disruption leads to a variety of health issues, including abnormalities in hormone levels, metabolism, and reproductive health.

Thyroid disorders are prevalent among individuals with lead exposure. Lead interferes with the production of thyroid hormones, which play a crucial role in regulating metabolism and energy levels. This disruption often leads to hypothyroidism or an underactive thyroid, causing symptoms such as fatigue, weight gain, and depression.10

In addition to thyroid disorders, lead exposure has also been linked to polycystic ovary syndrome (PCOS). PCOS is a common hormonal disorder among women of reproductive age, characterized by irregular periods, excess hair growth, and fertility issues.11

Detoxing Lead From The Body

The only solution to dealing with lead toxicity is to remove it from the body. Removing heavy metals from the body requires patience, but is the only way to receive lasting relief from heavy metal-induced health problems.

Oral chelation therapy is used to detoxify the body from harmful heavy metals, like lead and mercury. Chelation therapy works by binding to the lead molecules in the body and removing them through urine excretion. This process helps to reduce the overall levels of lead in the body and mitigate its harmful effects. While traditional chelation therapy is administered intravenously, oral chelation therapy offers a less invasive and more convenient option.

One of the key benefits of oral chelation therapy is that it can be easily done at home without the need for hospital visits or medical supervision. This makes it a more affordable and accessible treatment option.12

Are Stainless Steel Cups A Healthy Option?

Stanley and their competitors make their cups out of stainless steel. One of the main advantages of stainless steel is its durability. It is resistant to corrosion, rust, and stains, making it a long-lasting option for drinking vessels. Even though the industry consensus is that stainless steel is non-toxic, that is not entirely true, as it has the potential to leach harmful chemicals into drinks.

Recent studies have shown that stainless steel may not be as safe as previously thought. When exposed to high heat or acidic foods, stainless steel can leach nickel and chromium into the food being cooked.13 Additionally, it was found that chromium and nickel from stainless steel leached into acidic fruit juice. Fortunately, stainless steel did not leach metals into distilled water with a pH of 7.14 

Nickel is a known allergen and exposure to it has been linked to respiratory disorders  and kidney problems.15 Chromium, on the other hand, can accumulate in the body over time and cause respiratory issues, skin irritation, and even liver damage.16

If you are going to use a stainless steel cup, avoid filling it with anything acidic or alkaline.

Are Plastic Bottles A Better Option?

No, plastic bottles are made from a material called polyethylene terephthalate (PET). This type of plastic has been found to leach endocrine disrupting chemicals into the liquid it holds, particularly when exposed to heat or sunlight.17

Additionally, a recent study found that the liquid held inside plastic bottles contain hundreds of thousands of micro-nano sized plastic particles.18 When we drink from these bottles, these plastic particles pass directly through our intestines and accumulate in our organs.19

Healthy Drinking Bottles – Glass

Glass is king when it comes to the best material for drinking bottles. First and foremost, glass is a non-porous material, meaning it does not allow any air or liquids to pass through its surface. This makes it easy to clean and prevents any bacteria or germs from being trapped in the vessel. Additionally, glass is also chemical-free and does not release any harmful toxins when in contact with liquids. This makes it a safe and healthy option for drinking bottles.

Moreover, glass is also environmentally friendly as it is recyclable and does not produce any toxic by-products during the manufacturing process. It also maintains the taste and purity of the beverages, unlike other materials that may affect the flavor of drinks. Furthermore, glass does not retain any odors or flavors, making it ideal for use with different types of beverages. Glass has one obvious downfall, as it breaks easily. However, from a health perspective, drinking out of glass is ideal.20

Stanley Cups Contain Lead – Should You Be Worried?

There are no safe levels of lead exposure. So while the risk of lead exposure from Stanley cups is low, if the cup is fully intact, the potential for lead poisoning is still present. Additionally, the potential for lead dust accumulation on all surfaces of the cup during the manufacturing process is also a possibility. Lead, combined with the potential dangers of drinking out of stainless steel, leave only one really decent solution, reusable glass drinking bottles.

In any case, whatever cup you choose, don’t fill it with tap water if you value your health.
