On a sunny morning, Wei Shaojie, a healthy middle-aged man, and his friend, Li Hao, a senior nutritionist, went to the suburbs to climb a mountain.
On the hillside, they stumble upon an elderly man picking herbs, a scene that sparks a discussion between the two about health and diet.
"You know what? Nowadays, many elderly people have all kinds of problems because of improper diet.
Like tofu, although it is highly nutritious, it is not suitable for everyone to eat in large quantities. Li Hao started the topic while adjusting his trekking poles.
Wei Shaojie is a food lover, but he doesn't know much about the science behind food.
Li Hao's words made him a little curious, why did tofu become a minefield for the elderly?
Li Hao explained that tofu is rich in calcium and plant-based protein, but for some older people with specific health problems, the calcium-rich content of tofu may aggravate their condition.
Especially for those patients with renal insufficiency, foods high in calcium may lead to excessive calcium deposition in the body, which can exacerbate the burden on the kidneys and even induce or aggravate the risk of kidney stones.
"There was a patient who was old and didn't have very good kidney function. But he was particularly fond of eating tofu, and was soon admitted to the hospital with kidney stones. Li Hao recalled.
After Wei Shaojie heard this, he couldn't help but feel a little worried. His father is also a lover of tofu, and he is old, so he doesn't know if there is such a hidden danger.
So he asked Li Hao if there was a way to balance nutrition without causing health problems.
Li Hao suggested that for the elderly, it is important to have a balanced diet and adjust the diet structure according to the health of the individual.
He elaborated on several alternatives to tofu, such as chicken breast, which is rich in high-quality protein but low in calcium, or fish, which is rich in omega-3 fatty acids, which are good food options for kidney function.
Further, Li Hao also mentioned a study that covered data on the correlation between eating habits and health status of thousands of older people.
The data shows that those elderly people who consume too much calcium food are indeed more likely to develop problems such as kidney stones than ordinary people.
The more Wei Shaojie listened, the more he felt that it made sense, and decided to help his father adjust his eating habits when he returned home.
He also wondered if there were other health risks to be aware of from these foods, in addition to their effects on the kidneys.
Li Hao explained that every food has its double-edged sword characteristics.
For example, while fish is a source of high-quality protein, excessive intake can also lead to mercury poisoning.
Therefore, it is crucial to maintain dietary diversity and moderation and avoid over-intake of any one kind of food.
Finally, Li Hao and Wei Shaojie were overlooking the scenery on the top of the mountain, and Li Hao suddenly asked, "Why do you think people are so prone to eating and drinking now?"
This question made Wei Shaojie think for a long time, and he realized that although modern people are rich in food, their understanding and application of food are often skewed, which may be an important factor leading to frequent health problems.
This discussion made him deeply feel that healthy eating is not only about choosing the right food, but also about having a scientific concept of diet and a reasonable diet structure.
Reflecting on today's conversation, he thought further: how can we make more people aware of the importance of eating properly and make adjustments according to their own health?
This issue needs to be analyzed and implemented in depth from various aspects such as education and social publicity.
