Whey vs. Casein
Cow’s milk is composed of carbohydrates and two main dairy proteins: casein and whey. When milk is coagulated, it automatically divides out the proteins into semi-solid lumps and a liquid portion. Casein is found in the lumps, or curds, whereas the whey protein is found in the liquid portion (5). The ratio of protein within a glass of milk is about 20% whey to 80% casein, which provides an optimal composition of readily available nutrients to replenish body fuel post-workout and keep energy levels up (5).
(1)ये फल गर्मी में आपके बॉडीगार्ड हैं
गर्मियां आते ही डिहाइड्रेशन की समस्या होने लगती है। तेज गर्मी से कई बार लू भी लग जाती है। लेकिन प्रकृति ने हमें ऎसे कई फल उपहार में दिए हैं जो पोषक तत्वों से भरपूर होने के साथ-साथ शरीर में पानी की कमी भी नहीं होने देते। आइए जानते हैं इन रसीले फलों और उन्हें खाते समय बरती जाने वाली सावधानियों के बारे में।
गर्मी में राहत देगा तरबूज
तरबूज में पानी की मात्रा काफी ज्यादा होती है, जिससे डिहाइड्रेशन की समस्या नहीं होती। फाइबर होने से यह आसानी से पच भी जाता है और आपका वजन भी नहीं बढ़ता। फ्रिज में रखे हुए तरबूज को भी एक दिन में खा लेना चाहिए।
ध्यान रहे
2-3 स्लाइस काफी। डायबिटीज में तरबूज ना खाएं।
मोटापा घटाएगा खरबूजा
डॉ. विनोद गुप्ता के अनुसार खरबूजा रक्तचाप को भी नियंत्रित रखता है। इससे दिल के रोग की आशंका कम होती है। यदि सीने में दर्द की शिकायत हो तो वह भी ठीक हो जाती है। इससे मोटापा नहीं बढ़ता। चेहरे पर दाग, धब्बे हों, तो खरबूजे का रस लगाएं। लू लगने पर इसके बीजों को पीसकर माथे पर लेप करें।
शेक, जूस से बढिया ताजा आम
शेक, जूस या अमरस के बजाय आम को ताजा फल के रूप में ही खाएं ,क्योंकि इसमें शुगर भरपूर मात्रा में होती है, ऎसे में इसमें चीनी मिलाकर बनाए जाने वाले खाद्य और पेय पदार्थ सेहत को नुकसान पहुंचाते हैं। कच्चे आम के पने से गर्मी और लू से राहत मिलती है। ध्यान रहे- एक आम काफी। डायबिटीज में ना खाएं।
तनाव से बचाएगा संतरा
यह विटामिन सी से भरपूर होता है। इसमें मौजूद पोटेशियम व फोलिक एसिड, कोलेस्ट्रॉल व ब्लड प्रेशर को नियंत्रित रखते हैं और दिमाग में ऑक्सीजन के संचार में सहायता करता है, जिससे तनाव दूर होता है। इससे हडि्डयां और दांत मजबूत होते हैं।
ध्यान रहे- एक संतरा काफी। किडनी रोगियों को संतरा नहीं खाना चाहिए।
कब्ज दूर करेगा पपीता
पपीते में मौजूद फाइबर कब्ज नहीं होने देता। इसे खाने से पेट जल्दी भरता है और आप ज्यादा खाने से बच जाते हैं। जिन्हें डायरिया की समस्या हो वे पपीता ना खाएं। डाइटीशियन डॉ. नमिता पनगडिया के अनुसार बाजार की फ्रूट चाट की बजाय घर पर फल धोकर व काटकर खाएं। फल खाने के कम से कम आधे घंटे बाद ही कुछ खाएं।

Whey vs. Casein
Cow’s milk is composed of carbohydrates and two main dairy proteins: casein and whey. When milk is coagulated, it automatically divides out the proteins into semi-solid lumps and a liquid portion. Casein is found in the lumps, or curds, whereas the whey protein is found in the liquid portion (5). The ratio of protein within a glass of milk is about 20% whey to 80% casein, which provides an optimal composition of readily available nutrients to replenish body fuel post-workout and keep energy levels up (5).
Whey is known as the “fast-acting” protein, meaning that the body can break it down and absorb the nutrients relatively quickly (1). In some cases, manufacturers break down whey even further into whey protein isolate, whey concentrate or whey powder, which are then sold in different forms as supplements. These lactose-free, concentrated protein supplements are absorbed at a quicker rate than casein.
Additionally, whey is high in indispensible (essential), branched-chain amino acids that the body cannot produce on its own and must derive from food (1).
Additionally, whey is high in indispensible (essential), branched-chain amino acids that the body cannot produce on its own and must derive from food (1).
This allows for quick uptake by the body (6). Some studies have found that whey protein supplements may be associated with an increase in muscle mass size and strength in some individuals as well (7).
Casein, often referred to as the “slow-acting” protein, takes slightly longer to digest as it slowly releases amino acids into the bloodstream (6). It contains a different amino acid profile than whey and is particularly high in the conditionally indispensible amino acid, glutamine (1). This is beneficial because, when the body is put under physiological stress, such as with endurance exercise, the body needs to derive glutamine from an outside source of food (1). The bottom line, however, is that both whey and casein are needed for proper nutrition.
Some supplements contain both whey and casein to allow the body to take full advantage of the different absorption rates (1,8). Additionally, the combined efforts are beneficial because whey works to stimulate protein synthesis whereas casein inhibits the breakdown of protein (9). Therefore, individual, isolated supplements of either whey or casein may not be the best option.

Research shows that low-fat dairy is more effective at protein synthesis and replenishing net muscle protein balance than high-fat dairy (6). One theory is that the fat is digested at a slower rate than carbohydrates and protein, and thus the fat slows down the delivery of carbohydrates and protein to tissues (6).
Furthermore, chronic use of low-fat milk as a post-exercise resistance training meal has been associated with a greater reduction in overall body fat, increased muscle growth and greater muscle mass maintenance than soy-based proteins (3,9). Table 1 lists whole-food examples of post-exercise snack options that provide the optimal balance of carbohydrates to proteins. Eat these snacks within 30mins after completing an exercise session for optimal glycogen and protein uptake.

‘Close, cold neighbour of Sun found’
Astro-nomers have discovered the coldest star of its kind — as frosty as Earth’s North Pole — just 7.2 light years away. Using Nasa’s Wide-field Infrared Survey Explorer (WISE) and Spitzer Space Tele-scopes a Pennsylvania State University astronomer spotted the “brown dwarf” — a dim, star-like body.
Images from the space telescopes pinpointed the object’s distance at 7.2 light-years away, making it the fourth closest system to our Sun. “It is very exciting to discover a new neighbour of our solar system that is so close,” said Kevin Luhman, an associate professor of astronomy and astrophysics at Penn State. “In addition, its extreme temperature should tell us a lot about the atmospheres of planets, which often have similarly cold temperatures,” said Luhman. Brown dwarfs start their lives like stars, as collapsing balls of gas, but they lack the mass to burn nuclear fuel and radiate starlight.
The newfound coldest brown dwarf, named WISE J085510.83-071442.5, has a chilly temperature between minus 48 to minus 13 degrees Celsius. Previous record holders for coldest brown dwarfs were about room temperature. Although it is very close to our solar system, WISE J085510.83-071442.5 is not an appealing destination for human space travel in the distant future, researchers said.
“Any planets that might orbit it would be much too cold to support life as we know it,” Luhman said. “This object appeared to move really fast in the WISE data. That told us it was something special,” said Luhman. WISE was able to spot the rare object because it surveyed the entire sky twice in infrared light, observing some areas up to three times.
Cool objects like brown dwarfs can be invisible when viewed by visible-light telescopes, but their thermal glow, even if feeble, stands out in infrared light. Spitzer’s infrared observations helped to determine the frosty temperature of the brown dwarf.
