Fasting may protect against Alzheimer’s, Parkinson’s
Reducing your calorie intake could help your brain, but doing so by cutting your intake of food is not likely to be the best method of triggering this protection.”
Lead researcher Mark Mattson
People who fast one or two days per week are at a lower risk of developing degenerative diseases of the brain such as Parkinson’s and Alzheimer’s, US researchers say.
Many studies have already showed benefits of cutting daily calorie intake or fasting.
In their new study on lab mice, researchers at the National Institute on Ageing in Baltimore found that cutting food intake for one or two days a week could significantly prevent brain disease and even severe conditions such as stroke. ENTIRE ARTICLE AT SOURCE
Optional Fasting in Islam:
It was narrated that ‘Aa’ishah (may Allaah be pleased with her) said: The Prophet (peace and blessings of Allaah be upon him) was keen to fast on Mondays and Thursdays. Narrated by al-Tirmidhi, 745; al-Nasaa’i, 2361; Ibn Maajah, 1739; classed as saheeh by al-Albaani in Saheeh al-Targheeb, 1044.
3 – It was narrated from Abu Hurayrah (may Allaah be pleased with him) that the Messenger of Allaah (peace and blessings of Allaah be upon him) said: “Deeds are shown (to Allaah) on Mondays and Thursdays, and I like my deeds to be shown when I am fasting.” Narrated by al-Tirmidhi, 747; classed as saheeh by al-Albaani in Saheeh al-Targheeb, 1041.
The following ahaadeeth encourage fasting on three days of each month:
1 – It was narrated that Abu Hurayrah (may Allaah be pleased with him) said: “My close friend [the Prophet (peace and blessings of Allaah be upon him)] advised me to do three things which I will not give up until I die: fasting three days of each month, praying Duha, and sleeping after Witr. Narrated by al-Bukhaari, 1124; Muslim, 721.
2 – It was narrated from Mu’aadhah al-‘Adawiyyah that she asked ‘Aa’ishah, the wife of the Prophet (peace and blessings of Allaah be upon him), “Did the Messenger of Allaah (peace and blessings of Allaah be upon him) fast three days of every month?” She said, “Yes.” She said to her: “Which days of the month did he fast?” She said, “He did not mind which days of the month he would fast.” Narrated by Muslim, 1160.
3 – It was narrated from Jareer ibn ‘Abd-Allaah (may Allaah be pleased with him) that the Prophet (peace and blessings of Allaah be upon him) said: “Fasting three days of each month is fasting for a lifetime, and ayaam al-beed are the thirteenth, fourteenth and fifteenth.” Narrated by al-Nasaa’i, 2420; classed as saheeh by al-Albaani in Saheeh al-Targheeb, 1040.
4 – It was narrated that Abu Dharr (may Allaah be pleased with him) said: The Messenger of Allaah (peace and blessings of Allaah be upon him) said to me: “If you fast any part of the month, then fast the thirteenth, fourteenth and fifteenth.” Narrated by al-Tirmidhi, 761; al-Nasaa’i, 2424; classed as saheeh by al-Albaani in Saheeh al-Targheeb, 1038.
There is broad scope in the command to fast three days, as it says in the hadeeth of ‘Aa’ishah (may Allaah be pleased with her), but the best days of the month for fasting are the thirteenth, fourteenth and fifteenth, as it says in the other saheeh ahaadeeth.
