〔編譯陳成良/綜合報導〕日常飲食竟可能反映在大腦影像中?西班牙一項人體試驗發現,健康中年人每天攝取濃縮番茄製品持續3個月後,注意力與聯想記憶測驗表現有所改善,部分受試者的大腦功能性磁振造影(fMRI)也觀察到神經網絡連結出現變化。不過,研究規模較小,結果仍屬初步發現。
科學新聞網站《Science Alert》報導,這項由西班牙巴塞隆納大學(University of Barcelona)團隊進行的研究,成果5月19日刊登於國際期刊《抗氧化劑》(Antioxidants)。研究針對42名健康中年人採隨機交叉試驗,受試者分別接受番茄製品飲食及低茄紅素飲食。

試驗結果顯示,攝取番茄製品期間,受試者在選擇性注意力、處理速度及聯想記憶等測驗中的表現有所改善。研究團隊同時檢測血液中的茄紅素等指標,並進一步觀察大腦功能性連結變化。
僅14人接受腦部掃描 神經網絡出現變化
其中14名受試者接受功能性磁振造影檢查。影像分析觀察到額頂葉與聽覺等大腦神經網絡的連結出現變化,但這部分分析樣本較少,統計證據仍有限。
研究本身也存在未盲化等限制,受試者與研究人員都知道飲食安排,因此無法完全排除受試者心理預期或測驗投入程度造成的影響。此外,腦部影像分析只有少數受試者,不能據此推論吃番茄能預防失智或改善大腦退化。
這項研究目前仍是小型初步試驗,不能當作醫療或保健指引。研究真正提供的是一條新的生活營養研究線索:規律攝取番茄製品,可能與人體大腦神經網絡連結及部分認知表現變化有關,值得透過更大型、設計更嚴謹的研究進一步驗證。

Internet celebrity doctor Siska Bohart explains how caffeine blocks adenosine receptors to increase alertness, and explains its metabolic differences, health benefits and risks. He also recommends a daily intake limit of 400 mg, avoidance of intake 8 to 10 hours before bed, and pay attention to hidden sources of caffeine such as energy drinks and painkillers.

Director of Health Ronald Lam Man-kin warned that unvaccinated children and elderly in Hong Kong are four to five times more likely to suffer serious complications or death from flu, citing rising infections and hospitalization rates significantly above last year's levels.

As the Mid-Autumn Festival is approaching, the National Health Service reminds the public that mooncakes are high in calories. One traditional pine nut and lotus paste mooncake has about 720 calories, which is equivalent to 2.5 bowls of white rice. When grilling meat, you need to avoid scorching the ingredients and being exposed to oil fumes for a long time. Follow the three principles of "low calories, avoid scorching, and prevent oil fumes". It is recommended to choose a ventilated outdoor place, eat vegetables and fruits, and eat sugar-free to maintain a balanced diet.

After autumn, high temperatures may still occur due to "autumn tiger". Traditional Chinese medicine practitioners remind that the focus of heatstroke prevention should shift from simply preventing high temperatures to paying attention to body heat dissipation and water balance. If symptoms such as dizziness and headache occur, you should rest, cool down and rehydrate, and seek medical treatment if necessary.

Cai Xiaowen, chairman of the National Federation of Counseling Psychiatrists Associations of the Republic of China, pointed out that in recent years, the number of people seeking psychological counseling due to debt problems has increased, especially among those aged 45 to 64 who are under multiple pressures on finances, family, health, and care for relatives and friends, but are less accustomed to asking for help. The Ministry of Health and Welfare held a press conference on World Suicide Prevention Day, emphasizing changing the suicide narrative. Financial personnel will receive suicide prevention and gatekeeper education training to identify early signs of help and assist in referrals to psychological services.

A man in Taizhou, Zhejiang Province inserted a 55cm live eel into his body through his anus and suffered abdominal pain for more than 10 hours before seeking medical treatment. The doctor's examination found that the eel had stretched across multiple sections of the intestine, causing multiple ulcers, mucosal congestion and erosion. The man was successfully removed after a multi-disciplinary medical team worked together, and the man was discharged from the hospital smoothly after the operation.
