糖如何影響眼睛健康

Blood sugar and eye problems

As Sugar accumulates in the blood, it can cause various problems. One item on the list is vision problems. The eye is a delicate and complex structure, messing up any tiny components can cause serious vision problems.

Elevated blood sugar levels can cause inflammation and damage to the fragile blood vessels of the retina. It can also cause swelling and deformation of the lens in the eye, and possibly cataracts. High blood sugar (combined with insulin) can also cause blood vessels to narrow and prevent adequate drainage. This increases pressure in the eye (glaucoma), which damages the optic nerve and various blood vessels.

Diabetes and eye health

It has been established that the link between sugar and type 2 diabetes is very close, and people with diabetes face a higher risk of eye and vision problems than the general population . When blood sugar rises over time, as with uncontrolled prediabetes and diabetes, the tiny blood vessels at the back of the eye are damaged. These damaged blood vessels may leak fluid, swell and cause excessive pressure in the eye, and even trigger new blood vessels to start to grow in the eye. The resulting problems may include bleeding, scarring, and dangerous pressure.

Eye diseases commonly associated with diabetes include diabetic retinopathy, glaucoma, diabetic macular edema, and cataracts. All of these can cause partial or complete loss of vision.

Sugar can accelerate age-related vision problems

Another way sugar causes eye and vision problems is to accelerate the aging process. Aging and inflammation can cause problems such as macular degeneration , and this happens more quickly in people who consume a lot of sugar. Studies have shown that the higher the sugar content in the diet, the more likely people are to develop age-related macular degeneration in at least one eye.

How eye health affects overall health (and vice versa)

Your overall nutrition affects your eye health because your eyes need certain nutrients (such as vitamins A, B, C, and E) to function properly. Eating too much sugar will not leave enough room in the diet for the vitamins and other nutrients that the eyes need to work.

Turning things over, the health of your eyes will also affect your overall health. People with vision problems are more likely to suffer from heart disease , high blood pressure , back pain, depression, and diabetes.

Promote eye health

To maximize your eye health (and overall health), please consider the following lifestyle changes:

  • Give up sugar and choose healthier alternatives
  • Wear sunglasses to protect sensitive eyes from UV rays
  • Choose anti-inflammatory foods rich in essential vitamins and nutrients

o Examples include fish, low-glycemic carbohydrates such as brown rice, beans, nuts, vegetables and fruits

  • Avoid smoking
  • Minimize eye strain by taking a break from screen time and using an anti-glare screen
  • Wear protective glasses during sports, carpentry, welding and other activities.

By choosing a healthy lifestyle that aims to protect your eyes in the short and long term, you can prioritize your overall health and well-being.

龍珠悟空的「自在極意」:在現實科學究竟是怎麼一回事?

你可能有過這種體驗:臨睡未睡、剛醒未醒的一瞬間,腦海忽然變得超級靈活,點子像自動連線;等完全清醒,又好像沒那麼神了。動漫裡悟空進入「自在極意」像是把思考的阻力關掉,只剩本能與直覺在運作。科學上,這種「人間版自在極意」最接近的是入睡前後的邊緣狀態(N1/hypnagogia、或接近 REM 的過渡),它確實和創造力提升有關。

咩係三價鐵(Fe³⁺)同二價鐵(Fe²⁺)?

當我哋講「鐵質」時,唔止係話有冇攝取足夠,而係講緊鐵喺人體內唔同形態(尤其係三價鐵 Fe³⁺ 同二價鐵 Fe²⁺)點樣被吸收、轉化、運輸同儲存,呢啲都深深影響生物可利用率

全面解構低鐵原因、病理機制及影響

低鐵唔止係營養問題,仲可能係身體慢性警號

鐵質(iron)係人體不可或缺嘅微量元素,主要負責攜帶氧氣嘅血紅素(hemoglobin)製造、能量代謝、免疫調節等。當鐵質長期攝取不足、吸收差、或失去過多,就會導致「低鐵」(iron deficiency)甚至發展成「缺鐵性貧血」(iron deficiency anemia)。本文將從臨床醫學與分子生理角度,深入探討低鐵嘅成因、病理機制、生物轉化過程,以及其對人體造成嘅連鎖影響。

夢遺係唔係一定關性事?

夢遺,即係在無意識之下於睡眠中射精,係一種常見於青春期男生甚至成年男性身上的自然生理現象。夢遺唔等於一定發生性夢,也唔等於有性慾過強。它與睡眠週期中快速動眼期(REM sleep)嘅勃起模式有關,亦可能反映正常的荷爾蒙波動及精液排出節律。 咩係夢遺? 夢遺(nocturnal emission...
