Understanding the Hidden Dangers of LDL (Bad) Cholesterol
Last Updated on July 1, 2025 by Daily News Staff
(Family Features) These days, wellness information is practically everywhere you turn. Do this; don’t do that. Eat more of this; eat less of that. This is good for you; that is bad.
It can be hard to cut through all the noise, but the reality is, when it comes to something as serious as your heart health and LDL cholesterol – the “bad” cholesterol – ignoring it can be downright dangerous for your health.
According to the American Heart Association, about every 40 seconds, someone in the United States has a heart attack, and strokes occur at about the same frequency.
High LDL cholesterol, often called “bad” cholesterol, significantly increases your risk of heart disease.
A poll conducted by The Harris Poll for the American Heart Association revealed 75% of heart attack and stroke survivors reported having high cholesterol. Yet nearly half (47%) of heart attack and stroke survivors are unaware of their LDL cholesterol number. This lack of awareness shows more knowledge is needed to help survivors proactively manage their health.
In fact, knowledge is key to reducing your risk of heart disease. Understanding the impact of LDL cholesterol and knowing your LDL number can help you make informed decisions.
Cholesterol: The Good and The Bad
Cholesterol is a waxy, fat-like substance your body needs to build cells and produce hormones. However, not all cholesterol is created equal:
- LDL (low-density lipoprotein) Cholesterol: This is the “bad” cholesterol. When too much LDL cholesterol circulates in the blood, it can build up in the inner walls of the arteries that feed the heart and brain, forming plaque that can narrow and eventually block these arteries, leading to heart attack or stroke.
- HDL (high-density lipoprotein) Cholesterol: Known as the “good” cholesterol, HDL helps remove the “bad” cholesterol from the arteries, protecting against heart attack and stroke.
A Silent Threat
Many people think high cholesterol has obvious signs, but that’s not always the case. In fact, about half of U.S. adults and 42% of heart attack and stroke survivors mistakenly believe high cholesterol has clear symptoms. However, high LDL cholesterol typically doesn’t show any signs, which is why it’s known as a silent threat to your heart.
People who have had a heart attack or stroke are at higher risk of future cardiovascular problems, which is why it’s important to monitor your cholesterol regularly to help prevent future events.
It’s also important to know high LDL cholesterol can be genetic, meaning someone who eats a healthy diet and exercises regularly can still have high cholesterol. Additionally, the risk of high LDL cholesterol increases with age.
That’s why the American Heart Association’s “Lower Your LDL Cholesterol Now” initiative, nationally sponsored by Amgen, emphasizes the importance of regular cholesterol checks regardless of your weight, diet and physical activity levels. Knowing your LDL cholesterol number – and understanding the target levels based on your health history – gives you the opportunity to manage your health proactively. This enables you to make informed decisions to prevent future heart issues.
Know Your Number
You can reduce your risk of a heart attack or stroke by knowing and addressing your LDL cholesterol number.
Working closely with your doctor allows you to actively manage high LDL cholesterol – often a key risk factor you can help control – and together, you can develop a personalized treatment plan. Ask your doctor or health care provider for a cholesterol test to know your LDL number. Understanding your cholesterol number is the first step toward managing it effectively. If necessary, appropriate management of your LDL cholesterol can help reduce your risk of a heart attack or stroke.
Your doctor may also talk with you about your personal and family medical history; previous heart-related medical events such as a heart attack or stroke; lifestyle habits such as tobacco use, obesity, unhealthy living or aging; racial and ethnic backgrounds; and reproductive health.
Lower is Better
When it comes to your cholesterol, guidelines from the American Heart Association and the American College of Cardiology recommend “lower is better” to reduce your risk. Studies show that an LDL number or below 100 mg/dL is ideal for healthy adults.
If you have a history of heart attack or stroke and are already on a cholesterol-lowering medication, your doctor may aim for your LDL to be 70 mg/dL or lower.
Talk to your doctor about the right treatment plan for you. Positive lifestyle habits, such as exercising and eating a healthy diet, may also help.
However, if you’ve had a heart attack or stroke before, lifestyle changes alone may not be enough to lower your risk of another event. Your doctor may recommend cholesterol-lowering medications to protect your heart health.

Lactose intolerance is actually the human norm – but racism, the US government and business interests have made it into a condition
Lactose intolerance is the global human norm, but Western dietary standards, government policies and commercial interests helped frame it as a medical deficiency.
Hilary Smith, University of Denver
Lactose intolerance makes drinking milk or eating ice cream a literal pain. For some people, eating a dairy treat can lead to bloating, nausea and diarrhea. You might’ve experienced its effects yourself. If so, you may think of lactose intolerance as a defect rather than the norm.
But did you know that most people in the world today are lactose intolerant – and that the condition itself was invented in the 1960s?
“Surely you mean discovered, not invented,” I hear you saying. I don’t. As a historian who has traced the origins of nutrition-science ideas, I have chosen the word “invented” on purpose.
Inventing lactose intolerance
Variations in people’s ability to digest lactose first came to scientists’ attention after American dairy producers found a way to rid themselves of a postwar milk surplus. To offload what they couldn’t sell, they looked to the government to intervene. And it did, buying the excess and embedding it in school lunches and other places with publicly funded meals.
Suddenly, many people who had not habitually drunk milk were consuming it regularly, including not only some Americans but also people overseas. Part of that same milk surplus found its way into school lunches in places such as Japan and Taiwan in the 1950s as the American government began to sell milk to allies during the Cold War.
Many of the groups drinking milk regularly for the first time did not like it. In fact, it made them feel sick. Intrigued, scientists set up experiments to figure out why. In a 1966 study comparing how Black and white people incarcerated in Baltimore metabolized lactose, researchers found that Black participants had lower levels of lactase – the enzyme that breaks down lactose – in their guts.
To the white scientists conducting this study, the trouble that the Black prisoners had digesting milk looked like an “inborn error of metabolism.” They assumed that the normal human state was lactose tolerance and that the lactose intolerant had inherited a genetic mutation.
It was only after years more work with research participants of many races that experts realized that, as one National Institutes of Health official put it in 1981, “lactose intolerance is a normal physiological condition, shared by every adult animal except for certain ethnic and racial groups in man.” People of northern European descent, it turned out, were the weird ones. It was their ancestors who had passed down a genetic mutation – one that made them able to digest milk after infancy.
In short, what scientists discovered in the 1960s was that different bodies process milk differently. What they invented was the idea that lactose intolerance is a defect. Accepting that framing would mean nearly two-thirds of the human population – the estimated prevalence of lactose intolerance worldwide – is defective.
Instead of acknowledging that dairy-free diets can be healthy, people innovated ways to overcome this supposed disability so everyone could consume more.
Nutritional imperialism
Lactose intolerance is one example of what I call nutritional imperialism: a way of thinking that treats white diets as the norm and everyone else’s as an aberration.
Nutritional imperialism was common in the 20th century, when scientists thought that not only milk-rich but also meat-heavy diets were best; they considered diets outside of the United States and Europe too vegetarian. Some also argued that wheat flour, not rice, ought to be the universal staple.
The same bias applied to bodies. Besides faulty lactose digestion, nonwhite bodies were accused of other failures, too, such as aldehyde dehydrogenase deficiency, an inability to digest alcohol quickly. The less technical term for this may be more familiar: Asian flush.
Such differences might have been thought of as variety, just another way of being human. Instead, each became a deficiency.
Many people today have inherited and perpetuated this way of thinking without knowing it, including those who are deemed deficient by it. In 1959, the director of Japan’s nutrition bureau declared that “rice-eating peoples” such as the Japanese were “resigned and passive” and could correct this by imitating Western diets and switching to wheat.
Today, the most prominent scientist promoting the idea that Asian flush is a disease is a geneticist of Taiwanese descent who started a research consortium to study “the most common human enzymopathy in the world.”
The Chinese Nutrition Society placed a tall glass of milk next to its 2022 Food Guide Plate – never mind estimates that the vast majority of Han Chinese, the largest ethnic group in China and worldwide, are lactose intolerant.
Turning sickness back into difference
Science that pathologizes difference helps racism persist.
In recent years, white supremacists have embraced the concept of lactose intolerance as a distinguishing debility of nonwhite people. Social media users have copied and pasted a map of the geographic distribution of lactose tolerance originally published in the scientific journal Nature into racist chat threads on the online discussion forum 4chan.
In 2017, internet trolls disrupted an anti-racist art installation with neo-Nazi chants and messily downed jugs of milk to accentuate their white identity.
Turning a lactose-digestion difference into a deficiency has done more to reinforce narratives of racial hierarchy than to improve public health. So here’s a suggestion: If you enjoy eating dairy, keep doing it; if you don’t, don’t – and know that there is nothing wrong with you.

3 Practical Ways to Build Financial Confidence
Financial Confidence: Economic uncertainty, fueled by persistent inflation, stagnant wages and a cooling job market, has led many Americans to feel like they’re falling behind, even when they’re doing many of the “right” things financially. This expert guidance can help you be more intentional with the choices you make so your spending reflects your priorities.
Building Financial Confidence
(Feature Impact) Nearly everyone is carrying some level of insecurity about their financial future, even those who are trying to plan ahead. Economic uncertainty, fueled by persistent inflation, stagnant wages and a cooling job market, has led many Americans to feel like they’re falling behind, even when they’re doing many of the “right” things financially.
Though many are paying down debt, saving for retirement and building an emergency fund, they’re still asking, “Am I doing enough?” In fact, only 21% of Americans are financially prepared and assured in their ability to protect their futures, according to Mutual of Omaha’s 2026 Protection Index Survey – a proprietary research study conducted with quantilope – which shows overall financial confidence has declined.
“Many people believe they need to wait until they have more money, more certainty or the perfect plan before taking action,” said Nate Hobson, vice president of sales, Advisor Network at Mutual of Omaha. “But financial confidence is usually built through consistency rather than perfect timing. Even small steps today can make a meaningful difference over time.”
While being financially secure means different things to different people, according to the survey – such as having little or no debt (34%), owning a home (29%), maintaining emergency savings (27%), saving for retirement (26%) or having insurance coverage (26%) – building financial confidence doesn’t have to translate to cutting out everything you enjoy. Instead, this expert guidance can help you be more intentional with the choices you make so your spending reflects your priorities.
Create a Financial Cushion
Whether it’s a car repair, medical bill or temporary loss of income, unexpected expenses happen.
Having even a modest emergency fund can reduce financial stress and reliance on credit cards or loans. If saving several months of expenses feels overwhelming, start with a smaller milestone. Consistency matters more than the starting amount.
Put Good Financial Habits on Autopilot
One of the easiest ways to make progress is removing the need to make the same decision every month. Consider setting up automatic contributions to savings and retirement accounts, regular investment deposits and automatic bill payments, which can help you build financial security even during busy or uncertain times.
Taking a look at everyday spending habits can also make a difference. The survey showed small, everyday choices add up over time, such as cutting non-essential spending (57%), using rewards programs (54%), comparing prices or switching providers (39%) and following a monthly budget (38%). That could mean bringing your lunch to work instead of grabbing takeout, taking a few extra minutes to compare prices at the grocery store or using rewards to get more value from the purchases you’re already making.
Protect What You’re Building
Saving and investing are important pieces of financial protection, but they’re only part of the equation. Protecting income, loved ones and other financial assets is equally important.
For families, life insurance can provide financial protection during key earning and caregiving years, helping replace income if the unexpected happens. For those focused on covering final expenses, guaranteed whole life insurance can help cover funeral and other end-of-life costs. If you’re approaching or living in retirement, an annuity may provide a reliable stream of income that can complement other retirement resources and reduce uncertainty.
A financial professional can help determine which options best fit your goals and circumstances. To see how much coverage is right for your situation, Mutual of Omaha’s Life Insurance Calculator can provide a personalized estimate based on your income, financial obligations and long-term goals.

Taking Action with an Extra $1,000
If you unexpectedly received $1,000, your response with the extra cash may reveal your financial priorities and where additional planning could strengthen financial resilience.
Providing a window into Americans’ financial priorities, respondents in Mutual of Omaha’s 2026 Protection Index Report said they would:
- Pay down debt (25%)
- Add it to savings (21%)
- Use it for everyday expenses (14%)
- Invest it (9%)
