Is Eating Too Much Lobster Bad For You?

With 124 mg of cholesterol per 3 ounces of cooked meat, lobster is regarded as a food high in cholesterol. This quantity was originally thought to be roughly half of the daily intake guideline for healthy individuals and roughly two-thirds of the limit for those at risk for heart disease. This was due to the belief that consuming excessive amounts of dietary cholesterol would raise the risk of developing cardiovascular disease.

“But contrary to what we once believed, the cholesterol in the foods we eat, including lobster, has significantly less of an impact on blood cholesterol (for most healthy people). Unsaturated, trans, and saturated fats have a greater effect on blood cholesterol than other types of fats do “Rawn adds. In fact, based on studies showing that dietary cholesterol is not actually strongly associated with an elevated risk for cardiovascular disease, the USDA removed the advice to restrict dietary cholesterol to 300 mg from the Dietary Guidelines for Americans in 2015. The recommendations recommend increasing consumption of unsaturated fats while decreasing intake of saturated fats and eliminating trans fats from the diet.

While many foods that are high in cholesterol are also high in saturated fat, such as some types of red meat and some dairy products, and should still be limited, lobster and other shellfish, such as shrimp, have relatively little saturated fat and are a healthy source of protein for many people.

According to studies conducted on both men and women, certain persons may be “hyper responders” to dietary cholesterol, which means that eating foods high in cholesterol, such as shellfish and eggs, does raise blood cholesterol levels and, more crucially, the LDL/HDL ratio (which may increase risk for cardiovascular disease). The research does maintain that some dietary cholesterol is probably not an issue, even among hyperresponders.

Nutrition 101 for lobster meat

Essentially, lobster is a high-protein food with few calories and fat. 1 cup of the cooked meat will provide you with the following:

  • calories in 128
  • protein in 27 grams
  • Fat in 1.2 grams
  • Carbs in 0 grams
  • 198% of the copper daily value (DV)
  • your DV for selenium is 190%
  • a 53% daily value for zinc
  • Vitamin B12 intake: 51% of your DV

Additionally high in omega-3s and low in mercury is lobster. So it’s a fairly good option for safe, healthful fish.

The cholesterol content of lobster is the sole possible drawback. A single serving contains almost 70% of the recommended daily intake. But unless you have a higher chance of developing heart disease, that isn’t necessarily an issue.

The Lobster’s Downfall

People often avoid seafood due to the cost and preparation. The cost of premium lobster can be high. It can be difficult to prepare and serve lobster (without using all the butter). However, lobster has a few nutritional drawbacks as well.

Sodium levels in lobster and other shellfish are frequently high. Each 3-ounce serving of lobster has roughly 13 mg of sodium. a

Each day, your body requires about 500 milligrams of sodium. However, a teaspoon of table salt has around 2,300 milligrams. Numerous harmful outcomes may result from consuming too much salt, such as:

  • elevated blood pressure
  • Heart attack risk
  • stroke danger

The majority of seafood, including lobster, is high in potassium. Each 3-ounce dish of lobster contains roughly 9 milligrams of potassium.

The opposite of sodium, potassium serves a different purpose. This is normally beneficial, however individuals with illnesses like kidney disease or those who take specific drugs may have potassium toxicity from a high-potassium diet.

Almost all seafood, including lobster, contains traces of mercury. Mercury can have negative effects on developing children and unborn children. Young children and women who might become pregnant, are pregnant, or are nursing should avoid seafood that has high levels of mercury.

To find out more about the potential mercury concentration of the seafood you want to eat, find out what kind it is and where it came from.

contamination with heavy metals

Heavy metals including mercury, lead, cadmium, and arsenic may infect lobsters and other shellfish as a result of water pollution (1).

Your health could suffer if you consume heavy metals through diet. It may harm the kidneys, the brain, the heart, and the developing brains of babies (1, 44, 45).

However, the FDA considers lobster to be a low-mercury meal and advises against eating more than two to three plates of lobster each week (46).

The consumption of heavy metals should be restricted in those who are breastfeeding, pregnant, or otherwise susceptible to their effects.

Heavy metals and microbes that cause foodborne diseases may taint lobsters. Additionally, they are very allergenic.

Eat moderate amounts of tomalley, advises Health Canada for lobster enthusiasts.

SUZHOU — The tomalley found in lobsters may contain natural poisons, as Health Canada is reminding Canadians who consume them.

The lobster’s body cavity contains a soft, green substance called tomalley. It performs the roles of the liver and pancreas and ordinarily removes pollutants from the environment, such as toxins linked to paralytic shellfish poisoning. A person’s health could be harmed by eating food that contains paralytic shellfish poisoning toxins.

According to previously gathered data by the Canadian Food Inspection Agency, it’s possible for a very small percentage of lobsters to have paralytic shellfish poisoning toxins in the tomalley at levels high enough to pose a risk to consumers if the tomalley is consumed. Eating fresh or canned lobster flesh has minimal health risks because paralytic shellfish poisoning toxins are typically absent from lobster meat.

Certain species of microscopic marine algae prevalent in coastal waters naturally create the toxins that cause paralytic shellfish poisoning. If consumed in sufficient quantities, the toxin can seriously harm the nervous system of humans. A tingling sensation or numbness of the lips right after eating are signs of a modest exposure. Larger exposures can cause these symptoms to spread to the arms and legs as well as headaches, nausea, and dizziness. In rare instances, more serious disorders such muscular paralysis, breathing problems, choking, and even death can result from delayed medical care.

It is not advisable for kids to eat lobster toast. Consumption of lobster tomalley by adults should be limited to one cooked lobster per day at most.

What Are the Cholesterol Effects?

It’s well knowledge that lobster contains a lot of cholesterol. And it is in comparison to certain other foods. For instance, a 31/2-ounce portion of lean top sirloin steak has 64 mg of cholesterol while the same portion of lobster has 145 mg. However, compared to an egg, which has 187 mg of cholesterol, a plate of lobster actually has less of it. According to Rimm, dietary cholesterol isn’t as significant as previously believed. Dietary cholesterol is “not closely associated to a rise in blood cholesterol or heart disease in the context of an overall healthy diet.”

When it comes to controlling your cholesterol levels and risk of heart disease, saturated fat should take priority. Additionally, lobster has very no saturated fat.

It has been demonstrated that eating a diet high in saturated fat raises blood cholesterol levels overall and tips the scales against “good” HDL and “bad” LDL cholesterol. Because of this, the current dietary recommendations advise keeping your daily calorie intake of saturated fat to no more than 10%. Additionally closely connected to a higher risk of heart disease is saturated fat. According to a 2016 study published in The BMJ, those with diets rich in saturated fat had an 18% higher risk than those with diets low in saturated fat.

However, pay attention to the quantity of your lobster piece if you’re worried about dietary cholesterol. Half a lobster is often offered, according to Dong. That much lobster meat weighs roughly 8 ounces and has about 300 mg of cholesterol in it.


Overall, lobster is a good source of protein, vitamins, and minerals when consumed in moderation, but it does have certain disadvantages. 71 percent of the daily maximum cholesterol guideline and 31 percent of the daily maximum salt are found in a serving of 1 cup. Consuming too much sodium and dietary cholesterol increases blood pressure and increases the risk of heart disease and stroke, respectively. Avoid seasoning lobster with salt and butter before eating.

Why eating lobster is unhealthy?

Lobster is a lean, low-calorie source of protein with 89 calories, 19 grams of protein, and less than 1 gram of fat per 3-1/2-ounce serving.

The nutritional value of lobster is comparable to that of other shellfish. According to Faye L. Dong, Ph.D., professor emerita of food science and human nutrition at the University of Illinois, “lobster contains a large amount of minerals, such as zinc, calcium, phosphorus, selenium, and potassium, as well as B vitamins.” Additionally, it is a low-mercury variety of shellfish. Because mercury, a heavy element, can harm the brain and nerves, it is important to avoid eating fish if you are a woman of childbearing age or a young child.

Even while it doesn’t contain as much of the beneficial omega-3 fats as certain other kinds of fish, a 31/2-ounce portion still provides 83 mg of these nutrients. According to Eric Rimm, Sc.D., professor of epidemiology and nutrition at the Harvard T.H. Chan School of Public Health, “if you eat lobster one day a week and a fattier fish like salmon one or two times a week, you’ll have your omega-3 intake covered for the week.”

Is eating lobster every day healthy?

In fact, lobster is a good source of protein and necessary elements for the majority of diets. Phosphorus, which supports kidney function, is abundant in lobster. Additionally, a 3-ounce dose delivers more than 10% of your daily needs for magnesium.

When should lobster not be consumed?

You might be unsure if the lobster is still safe to eat if it has been more than four days (or four months for frozen lobster). Fortunately, poor lobster meat is rather simple to identify. You can spot a few telltale indicators that will indicate whether or not you need to reheat it in the oven:

  • If you take a good sniff of your bag or box of lobster, do you immediately recoil? If after just a quick whiff you find yourself scrunching up your nose, it’s probably best to throw the meat away rather than consume it.
  • supple, cottage cheese-like texture Even if your lobster meat smells fine, it might not be safe to consume. Check it out after removing it from the bag. Does it still have that same firm, rough texture that it had when you first cooked it? Or does it have a soft, almost cottage cheese-like feel? If the latter is the case, your lobster has degraded.
  • Does the lobster meat on your plate feel slimy to the touch? Do you frequently grab for the napkins as soon as you handle something? The lobster meat may then be spoilt on your hands.
  • Meat that is discolored: Check out your lobster carefully. Your meat has clearly gone bad if it has become discolored or has even started to turn green or white in some spots.
  • You’re just unsure: It’s possible that the tests you ran above produced conflicting results. It occurs. In this case, it’s advisable to discard it rather than run the danger of contracting food poisoning.
