In this fast-paced society, people are always looking for food that is both convenient and satisfying, and corn has undoubtedly become a frequent guest on many people's tables.
However, have you ever wondered what kind of effect this daily consumption of corn, especially as a staple food, will have on our body? First of all, we have to understand that corn is indeed very nutritious. It is rich in fiber, vitamin C, and some essential minerals.
However, there are always two sides to the story, and for those who like to eat boiled corn every day or replace the staple food with corn, such a diet may become a "hidden killer" of health. Why, you may ask?
Let's take a look at some of the characteristics of corn specifically. Corn is high in sugar and carbohydrates, and although it is satisfying to eat, these sugars and carbohydrates will be converted into a lot of calories and fat in the body after excessive consumption, especially for those who lack enough exercise, which can easily cause weight gain, and over time, it may cause or aggravate chronic diseases such as heart disease.

Again, our friends with heart disease may need to be extra careful. Did you know that although corn is rich in fiber and helps control blood sugar, it is also a high-sugar food? For people with diabetes or heart disease, excessive intake of high-sugar foods can increase the burden on the heart, making it more difficult to control blood sugar and increasing the risk of heart attack.
Not only that, corn also contains a substance called phytic acid, which can bind to minerals such as calcium and iron in the body, affecting the absorption of these minerals.
For older people or people with pre-existing problems such as osteoporosis and anemia, long-term consumption of large amounts of corn may make these symptoms worse.
So, while corn is a good thing, 'everything is poisonous, it's all about the dose', and eating corn in moderation can add color to our diet, but excessive consumption of it as a daily staple food can pose a potential threat to our heart health. Don't look at it yellow and clear, smile so sweetly, it's okay to be greedy occasionally, but you can't get along with it all day long, be careful that your body will protest.
At this point, do you have a deeper understanding of the relationship between corn and heart health? Well, that's the first part of our talk today about corn and heart health. If you'd like to dig deeper, let me know as we move on to the benefits and harms of corn and what foods to avoid when you have a bad heart.
Of course, let's talk about the pros and cons of corn, this time from a lesser-common perspective. First of all, the benefits of corn have to be mentioned is its antioxidant capacity.
You may have heard that blueberries and red grapes are antioxidants, but did you know that the xanthin and zeaxanthin in corn are also very powerful antioxidants? Moreover, zeaxanthin is especially good for our eyes. It is one of the main components that make up the macular area of the eye and can effectively reduce the risk of macular degeneration due to aging.
Therefore, eating corn regularly is beneficial for maintaining eyesight and reducing eye strain. Let's talk about the fiber of corn. Corn is high in fiber, which is good news for our digestive system.
Moreover, the presence of fiber can also help us better control blood sugar, which is undoubtedly good news for diabetics.
On the downside, while corn has many benefits, it's not flawless, and high carbohydrates can easily be converted into sugar and fat in the body if left in moderation, which can lead to obesity and increase the risk of chronic diseases such as heart disease and diabetes.
Finally, we cannot fail to mention the effects of pesticides and fertilizers that corn can be affected during its growth. In modern agriculture, in order to increase yields, many corn fields are heavily used with chemical fertilizers and pesticides, which may remain on the corn kernels and pose a potential threat to human health. Choosing organic corn or making sure it is washed thoroughly is one way to reduce this risk.
Although corn is good, it is necessary to pay attention to balance and moderation when eating. Not only does it provide a wealth of nutrients but it also helps us fight disease, but it can cause some health problems if consumed in excess or in an improper way.
In our daily diet, we should be varied and balanced in nutrition, so that food can become an assistant to our health, rather than a source of problems. Let's continue to talk about friends with bad hearts, which foods that seem harmless but may actually affect heart health should be eaten less.
First of all, most people agree that bananas are healthy because they are rich in potassium, which helps regulate heart rate and blood pressure. However, for those with heart disease who use certain types of β-blockers or diuretics for their illness, excess potassium may not be a good thing.
These drugs increase potassium retention in the body, and if large amounts of potassium are consumed through food, they can cause abnormally high potassium levels in the blood, which can cause arrhythmias. Patients with heart disease should adjust their banana intake under the guidance of a doctor during the medication.
Next is full-fat dairy products. But its high levels of saturated fats are not heart-friendly, and they increase levels of LDL (bad cholesterol) in the body, which can accumulate in the walls of blood vessels, increasing the risk of heart attack and stroke. Therefore, people with a bad heart should try to choose low-fat or fat-free dairy products.
The third one that might surprise you is coconut oil. Coconut oil has been widely advertised as a health food in recent years, but it actually contains a lot of saturated fat, which is not good news for the heart. People with heart disease should use coconut oil with caution.
While pork is a good source of iron and protein, it's also high in fat and cholesterol and may not be very heart-friendly, so it's a wise idea to cut back on these processed pork intakes if your heart health worries you. So, while these foods are common in our diet and maybe you eat them every day, if you have a bad heart, you need special attention.
Healthy eating isn't just about choosing what foods to eat, it's about understanding how those foods affect our body, especially the health of our heart. Remember, eat healthily, so that the heart does not "strike" and serves us for a long time.
