CURD - Benefits, How to use & not to use

CURD - Benefits, How to use & not to use

Compiled from this exceptional blog - http://easyayurveda.com
Dr J V Hebbar MD(Ayu & Dr MS Krishnamurthy MD(Ayu), PhD.

Curd is the most commonly used milk product in most part of the world. But classical method of curdling is not carried by few of the people. In fact sour buttermilk or sour curd should be added to the boiled and cooled milk to prepare curd. It is called as ‘souring’.

But few use lemon, tamarind, vinegar, amla juice etc. Even though by these, curdling takes place, there is difference in the quality of curds. They may not be harmful. But true benefit of classical curd cannot be expected from those curds. To get desired quality and hence the benefits, 1:50 ratio buttermilk and milk are to be added.


Curds benefits, Side Effects As Per Ayurveda

Ayurveda, the Indian system of medicine explains curds benefits based on different types of curds. These types are explained as per the taste and method of production. If used wisely curds can be an excellent Ayurvedic home remedy for many health conditions.

General curd benefits: Curd has

Amla rasa – sour taste
Amla paka – undergoes sour taste conversion after digestion
Grahi – absorbent, useful in diarrhoea,
Guru – heavy to digest
Ushna – hot in nature
Vatajit – balances Vata
Increases Meda (fat), Shukra (semen), Bala (strength), Kapha, Raktapitta (bleeding disorders), Agni (digestion strength) and shotha (inflammation).
Rochishnu – increases taste

Useful in
aruchau – useful in anorexia
Vishamajwara – chronic, recurrent fever
Peenasa – rhinitis
Mutrakruchra – dysuria
Grahani – malabsorption syndrome

Vishamajwara – irregular fever,
Aruchi – Anorexia, lack of interest in food
Mutrakrichra – dysuria, difficulty to pass urine
Karshya – emaciation

It is generally harmful during autumn, summer and spring seasons. It is invariably harmful in diseases caused by the vitiation of blood, Pitta and Kapha.[225-227]

Types of curds according to Ayurveda:

Thick semi formed curds
Sweet curds
Sweet-sour curds
Sour curds
Very sour curds.

The method of preparation of curds is pretty much the same.

How to make curds?
  • During evening time, take 500 ml of boiled and cooled milk in a vessel.
  • Take previously made curds – two spoons. add this to the milk and keep it for one night.
  • Next day morning, curds is ready.
  • If you do not have two spoons of curds, pre-hand, then you can add one spoon of lemon juice to half a glass of milk. then milk curdles. use this curdled milk  two table spoons to the 500 ml of milk during evening and keep it for one night. next morning, curds will be ready next day morning.
  • If you wish the curds to be sour, then add about three to four table spoons of curds to 500 ml of milk.
  • Ayurveda explains different types of curd with different curds benefits.

The sweetness or the sourness of the curds depends on-How old is the curds – Older the curds, more the sourness.
Amount of curds added to the milk during making curds.

Chemically or microscopically there might not be much difference in these types of curds. But according to Ayurveda, different tastes have different effects over the body. Ayurveda considers the physical nature as well as the chemical nature of any food or herbs.

Curds benefits based on types:
Thick semi formed curds: This type of curd is not fully formed and does not has any particular taste. It is not good for consumption. It causes Tridosha imbalance and ill-health.

Sweet curds: It is the sweet and thick curds. It increases body fat and Kapha Dosha. It calms Vata and Kapha. Useful in certain blood and Pitta related diseases. It is a natural aphrodisiac.

Sweet-sour curds: Its qualities are similar to that of sweet curds.

Sour curds:It increases digestive fire, hot in nature and increases Pitta and Kapha.

Very sour curds:It also increases digestive fire, hot in nature and increases Vata and Pitta.

Overall, sweet curds are cold in nature and sour curds is hot in nature and improves appetite.

A few other types of curds and their benefits:

Curds prepared from goat’s milk is an excellent remedy to balance Tridosha. Used in respiratory conditions and to improve digestion.

Curds prepared from Buffalo milk takes a long time for digestion. Increases Kapha and calms Vata and Pitta. It is a natural aphrodisiac.

Curds prepared from fat-free milk is a natural coolant. Improves taste and digestive power. It is useful in digestive problems.

Curds mixed with sugar is an excellent thirst reliever. so also curds mixed with jaggery. It is also an aphrodisiac. It is good for those who wish to become fat.

Note: curds with sugar, on a daily basis is contra indicated, in healthy people for long term use.

In disease conditions involving excessive thirst, emaciated and persons seeking aphrodisiac treatment, curds with jaggery or sugar is indicated as part of the treatment.

Benefits of curds are innumerable if prepared and used wisely.

Curd consumption at night? Can You Take Curd At Night?

Curd At Night – Ayurveda explains curd as having sour mixed sweet property and it increase Kapha dosha in the body. The mucus generation is also attributed to the effect of Kapha. During night period, there is natural predominance of Kapha in the body. So, curd consumption at night will further increase kapha leading to many complications.

This is quite similar to exposing yourself to hot Sun in the afternoon hours, which is not recommended, because, afternoon period is naturally Pitta predominant period and sun exposure also increases Pitta.




Whenever there is swelling or inflammation, if curds is taken, it worsens the inflammation.

Note that these properties are attributed to sour curds.

Sour curd should not be consumed by making it hot (ushna).

Curds should not be consumed during night (nishi),

It should also not be consumed during spring and summer seasons.

However, sour curds mixed with soup of green gram, honey, ghee , sugar and amla is helpful in relieving Dysurea (difficulty in urination) and indigestion.

Solution:

Try avoid consuming curd at night. because night is basically Kapha predominant period. thus consuming curd at night is best avoided according to Ayurveda. Curd also increases Pitta. Hence, taking it at night might cause indigestion problem.

If at all you are accustomed to take curd at night, I know that old habits die-hard. so, mix a small pinch of pepper powder to curds and consume. (do not add too much. it may cause burning sensation). You may also try adding fenugreek powder if you can tolerate a slight tinge of bitterness. (but this superb combination will relieve all kinds of stomach pain generated due to indigestion).

Buttermilk is best substitute to curds at night. Buttermilk clears the channel and chucks mucus secretion.

Rules for using curd as mentioned in Charaka Samhita Sutrasthana 7

# One should not take curd at night;
# If one desires to take curd at night, it can be taken along with ghee, sugar, green gram soup, honey or Amalaka (Amla – Indian Gooseberry.)
# It should not be taken hot.
# If one does not follow these rules he is likely to suffer from diseases like fever, Raktapitta (bleeding disorders), Visarpa(Erysipelas), Kushta (skin diseases), Pandu(Anemia), Bhrama(dizziness) and Kamala (Jaundice).[61-62]

Q: sugar added curd or non sugar added curd. which is better?
A: If you are taking curds in the morning, then taking curd without sugar is better.

If you are taking curd at night, it is not recommended as per Ayurveda. But having it with little sugar is better, if you cannot resist it.

1. Shower Body Lotion From Curd:
100 ml curd and 4 cowries are taken together in a steel vessel and kept over night. Next day morning, this curd is taken and used while showering.
Useful in eczema.
It cleanses and clears the lesions instantly and quickens the healing process.


2. Curd Energy drink- Simple lassi
200 ml of curd is added with 20 gram of sugar candy and churned well. As per ones desire mango juice or sliced banana also can be added. A pinch or two of cardamom is added to it. – A cup of it is good to take, per day.

3. Anti Diarrheal Remedy With Curd:
50 ml of curd,
1 spoon of lime water,
2-3 gram of table salt and
a pinch of Ajwayin or Hingu(Asafetida) are taken together and mixed well.
This is given to drink to the patients who are suffering from chronic diarrhea followed with Indigestion, loss of appetite, bloating abdomen etc

4. How To Prepare Mouthwash With Curd?
1 spoon honey,
2 spoon of ghee and
4 spoon of curd are taken and mixed thoroughly.

This thick solution is used as mouthwash.
It is useful in in the cases of the mouth ulcers or blisters of the mouth caused due to chicken pox, oral thrush etc. This can be practiced 2-3 times a day.

5. How To Prepare Facepack Using Curd?
20 gram each of fresh and wet turmeric and carrot are taken and pounded well to obtain fine paste. To this 50 ml curd is added and mixed well. This is used as face pack. It enhances complexion and useful to get rid of blackheads.

Five Easy Yoga Poses For Common Health Problems


Child’s pose (balasana)
Five Easy Yoga Poses For Common Health Problems

Here are five simple postures to ease insomnia, headaches, indigestion, anxiety and lower back pain:
For insomnia, try the …

Child’s pose (balasana)

Poses that fold your body in on itself are calming and restorative, as opposed to back bends, which are energising. “Do this pose just before bed, aiming for at least five minutes,”  “You can even do it in bed in the middle of the night if you find yourself awake and unable to sleep.”

Kneel with your knees together or slightly apart, whichever is more comfortable. Lower your bottom onto your heels and fold forward to place your forehead on the floor (or as close as you can get – use a block or cushion to support your forehead if you can’t reach the floor). Arms can be stretched out in front, palms down, or alongside your body, with your fingers next to your toes.

Close your eyes and breathe slowly in and out through your nose. Quietly focus on your breathing.


For headaches …

Seated forward bend (paschimottanasana)

The seated forward bend

Headaches can be caused by anxiety and tightness in the neck and upper back, and this pose addresses both these areas. “Folding in on yourself forces introspection and is calming for the nervous system”

Sit on the floor with legs extended out in front of you, toes pointing to the ceiling and back straight. Inhale and lift your arms above your head. Exhale, tip your pelvis forward, bend your torso from the hips towards your thighs and move your arms forward towards your toes. Gaze into the gap between your feet.

“Try not to round your back, The ultimate aim is to reach your toes and have your head resting on your knees, but it’s not a competition. Just let your hands rest where you can comfortably get to with a straight back.”

Take five slow breaths. On each inhale, lift and lengthen the front of your torso. With each exhale, deepen the bend a little further. Come up slowly and give your legs a shake to release the muscles.

For indigestion …


Seated twist (ardha matsyendrasana)

The seated twist

Twists gently massage and compress the internal organs. “This compression, followed by release when you come out of the twist, stimulates the digestive organs,”  Sit on the floor with your right leg extended out in front of you, your spine long.

Place your left foot beside the outside of your right knee, sole on the floor. Tuck your left knee into the crook of right elbow and hug the knee. Placing your left fingertips on the floor behind you, twist your torso to slowly to look over your left shoulder.

On every inhale, lengthen your spine upward. On each exhale, deepen the twist a little further. Hold for five breaths, turn back to face forward and repeat on the opposite side.

For anxiety …


Tree pose (vrksasana)

The tree pose

Tree pose helps to calm a racing mind and induce concentration. “It helps to find clarity, instead of staying trapped in the thought process,” Your mind must be completely focused on this pose to prevent toppling over, leaving no room for worry.”

Stand with feet hip width apart. Inhale and grow a bit taller. Exhale and draw your shoulders down and belly button in. Roll your shoulders up and back, and bring your palms together in front of your chest. Find a point in front of you to focus on.

Place the sole of your right foot on to your inner left calf. You can stay there or use your hands to place your right sole on your inner left thigh. Keep lifting up tall and make sure the pelvis is in a neutral position. Allow the right knee to relax down.

Hold for up to five slow, deep belly breaths, then use your hands to gently release the foot from the inner thigh. Repeat on the other side.

For lower back pain …

Standing forward bend (uttanasana)

The standing forward bend

“This simple bend releases tightness in the lumbar spine using the weight of the head It also increases flexibility in the hamstrings down the back of the leg – tight hamstrings can cause lower back problems.”

Stand with feet hip width apart and bend slowly forward, hinging at the hip. Keep a soft bend in the knees to prevent straining the lower back. Aim for resting your hands on the floor, but just go as far as feels comfortable. Allow your arms and head to hang. Breathe deeply and slowly through your nose for a maximum of 10 breaths, then come up slowly, head and shoulders last. Move around a bit to loosen the stretched muscles, then repeat.

Lungs play a key role in blood production.

Lungs play a key role in blood production



An Unexpected New Lung Function Has Been Found - They Make Blood
Bec Crew ScienceAlert | http://www.sciencealert.com/an-unexpected-new-lung-function-has-been-discovered-and-it-could-disrupt-decades-of-scientific-thought

Researchers have discovered that the lungs play a far more complex role in mammalian bodies than we thought, with new evidence revealing that they don't just facilitate respiration - they also play a key role in blood production.

In experiments involving mice, the team found that they produce more than 10 million platelets (tiny blood cells) per hour, equating to the majority of platelets in the animals' circulation. This goes against the decades-long assumption that bone marrow produces all of our blood components.

Researchers from the University of California, San Francisco also discovered a previously unknown pool of blood stem cells that makes this happen inside the lung tissue - cells that were incorrectly assumed to
mainly reside in bone marrow.

"This finding definitely suggests a more sophisticated view of the lungs - that they're not just for respiration, but also a key partner in formation of crucial aspects of the blood,"
says one of the researchers, Mark R. Looney.

"What we've observed here in mice strongly suggests the lung may play a key role in blood formation in humans as well."

While the lungs have been known to produce a limited amount of platelets - platelet-forming cells called
megakaryocytes have been identified in the lungs before - scientists have long assumed that most of the cells responsible for blood production are kept inside the bone marrow.

Here, a
process called haematopoiesis was thought to churn out oxygen-laden red blood cells, infection-fighting white blood cells, and platelets - blood components required for the clotting that halts bleeding.

But scientists have now watched megakaryocytes functioning from within the lung tissue to produce not a few, but most of the body's platelets.

So how did we miss such a crucial biological process this whole time?

The discovery was made possible by a new type of technology based on two-photon intravital imaging - a similar technique to one used by
a separate team this week to discover a previously unidentified function of the brain's cerebellum.

The process involves inserting a substance called
green fluorescent protein (GFP) into the mouse genome - a protein that's naturally produced by bioluminescent animals such as jellyfish, and is harmless to living cells.

The mouse platelets started to emit bright green fluorescence as they circulated around the body in real time, allowing the team to trace their paths like never before.

They noticed a surprisingly large population of platelet-producing megakaryocytes inside the lung tissue, which initially didn't make much sense, seeing as they're usually associated with
bone marrow.

"When we discovered this massive population of megakaryocytes that appeared to be living in the lung, we realised we had to follow this up,"
says one of the team, Emma Lefrançais.

They found that this huge supply of megakaryocytes is actually producing more than 10 million platelets per hour in the lungs of mice, which means at least half of the body's total platelet production is occurring in the lungs.

Here's what it looks like:
Further experiments also revealed vast amounts of previously hidden blood stem cells and
megakaryocyte progenitor cells (cells that give rise to megakaryocyte and red blood cells) sitting just outside the lung tissue - about 1 million per mouse lung.

When the researchers traced the entire 'life cycle' of the megakaryocytes, they found that they likely originate in the bone marrow, then make their way to the lungs, where they start platelet production.

"It's fascinating that megakaryocytes travel all the way from the bone marrow to the lungs to produce platelets,"
says one of the team, Guadalupe Ortiz-Muñoz.

"It's possible that the lung is an ideal bioreactor for platelet production because of the mechanical force of the blood, or perhaps because of some molecular signalling we don't yet know about."

The researchers wanted to investigate if their discovery could have an effect on how we treat disorders such as lung inflammation, bleeding, and transplantation in the future, by transplanting lungs with fluorescent megakaryocyte progenitor cells into mice with low platelet counts.

The transplants produced a massive burst of platelets that quickly restored the depleted platelet counts to normal levels, and the effect lasted for several months.

Another experiment tested what would happen if the bone marrow wasn't playing a role in blood production.

The team implanted lungs with fluorescent megakaryocyte progenitor cells into mice that had been engineered to have no blood stem cells in their bone marrow.
As Michael Irving reports for New Atlas, they watched as the fluorescent cells from the transplanted lungs made their way to the bone marrow, where they not only helped to produce platelets, but also other key blood components, such as neutrophils, B cells and T cells.

The findings will need to be replicated in humans before we can know for sure that the same process is occurring within our own bodies, but the study makes a strong case for this hidden function in what could be one of our most underrated organs.

It will likely also prompt scientists to investigate further how the bone marrow and lungs work together to produce our blood supply.

"It has been known for decades that the lung can be a site of platelet production, but this study amplifies this idea by demonstrating that the [mouse] lung is a major participant in the process," Traci Mondoro from the US National Heart, Lung, and Blood Institute, who was not involved in the study,
said in a press statement.

"Looney and his team have disrupted some traditional ideas about the pulmonary role in platelet-related hematopoiesis, paving the way for further scientific exploration of this integrated biology."

10 MRI Scans, 10 Different Diagnoses on same patient

10 MRI Scans, 10 Different Diagnoses on same patient

Spine J. 2016 Nov 17. pii: S1529-9430(16)31093-2. doi: 10.1016/j.spinee.2016.11.009. [Epub ahead of print]
https://www.ncbi.nlm.nih.gov/pubmed/27867079
Variability in diagnostic error rates of 10 MRI centers performing lumbar spine MRI examinations on the same patient within a 3-week period.Herzog R1, Elgort DR2, Flanders AE3, Moley PJ4.


BACKGROUND CONTEXT:

In today's health-care climate, magnetic resonance imaging (MRI) is often perceived as a commodity-a service where there are no meaningful differences in quality and thus an area in which patients can be advised to select a provider based on price and convenience alone. If this prevailing view is correct, then a patient should expect to receive the same radiological diagnosis regardless of which imaging center he or she visits, or which radiologist reviews the examination. Based on their extensive clinical experience, the authors believe that this assumption is not correct and that it can negatively impact patient care, outcomes, and costs.

PURPOSE:
This study is designed to test the authors' hypothesis that radiologists' reports from multiple imaging centers performing a lumbar MRI examination on the same patient over a short period of time will have (1) marked variability in interpretive findings and (2) a broad range of interpretive errors.

STUDY DESIGN:
This is a prospective observational study comparing the interpretive findings reported for one patient scanned at 10 different MRI centers over a period of 3 weeks to each other and to reference MRI examinations performed immediately preceding and following the 10 MRI examinations.

PATIENT SAMPLE:
The sample is a 63-year-old woman with a history of low back pain and right L5 radicular symptoms.
OUTCOME MEASURES:

Variability was quantified using percent agreement rates and Fleiss kappa statistic. Interpretive errors were quantified using true-positive counts, false-positive counts, false-negative counts, true-positive rate (sensitivity), and false-negative rate (miss rate).

METHODS:
Interpretive findings from 10 study MRI examinations were tabulated and compared for variability and errors. Two of the authors, both subspecialist spine radiologists from different institutions, independently reviewed the reference examinations and then came to a final diagnosis by consensus. Errors of interpretation in the study examinations were considered present if a finding present or not present in the study examination's report was not present in the reference examinations.

RESULTS:
Across all 10 study examinations, there were 49 distinct findings reported related to the presence of a distinct pathology at a specific motion segment. Zero interpretive findings were reported in all 10 study examinations and only one finding was reported in nine out of 10 study examinations.

Of the interpretive findings, 32.7% appeared only once across all 10 of the study examinations' reports.

A global Fleiss kappa statistic, computed across all reported findings, was 0.20±0.06, indicating poor overall agreement on interpretive findings. The average interpretive error count in the study examinations was 12.5±3.2 (both false-positives and false-negatives). The average false-negative count per examination was 10.9±2.9 out of 25 and the average false-positive count was 1.6±0.9, which correspond to an average true-positive rate (sensitivity) of 56.4%±11.7 and miss rate of 43.6%±11.7.


CONCLUSIONS:
This study found marked variability in the reported interpretive findings and a high prevalence of interpretive errors in radiologists' reports of an MRI examination of the lumbar spine performed on the same patient at 10 different MRI centers over a short time period. As a result, the authors conclude that where a patient obtains his or her MRI examination and which radiologist interprets the examination may have a direct impact on radiological diagnosis, subsequent choice of treatment, and clinical outcome.

More time walking means less time in hospital

New study shows more time walking means less time in hospital

https://theconversation.com/new-study-shows-more-time-walking-means-less-time-in-hospital-71554


In my practice as a GP, I have been impressed by a few energetic and active 80 year olds who remain in good health while many their age have succumbed to various chronic diseases. So in 2005, when the University of Newcastle established a
large community based health study of people aged 55 to 80, I made sure we recorded the participants’ physical activity in detail.

A decade later, we can report the influence of physical activity on the need for hospital care as published in the
Medical Journal of Australia today.

We used pedometers to record daily step counts, giving a much more precise measure of activity than the usual self-report questionnaires. Median daily step counts ranged from 8,600 in the youngest to 3,800 in those over 80 years, and weekend days had on average 620 fewer steps than weekdays.

The inactive people (taking 4,500 steps per day) averaged 0.97 days of hospital care per year. The more active people (taking 8,800 steps per day) needed only 0.68 days of care per year. In our analysis we adjusted for the effects of age, sex, the number of illnesses people had when they started, smoking, alcohol intake and education.

We wondered if the causation might be running the opposite direction. That is, that sick people walk less rather than activity preventing illness. To test this idea, we repeated the analysis ignoring all hospital admissions in the first two years of follow up to remove the immediate effects of serious illness. The difference is shown in the graph below.

The association extends right across the range of activity levels, showing any activity is good for health, and the more the better. The participants in our study wore the pedometers from morning until night, so a lot of what we recorded as steps was general activity around the house or the workplace, not necessarily continuous walking.
Recent research shows any that activity is better than sitting down, so even light activity is protective of health. Pedometers don’t capture swimming or cycling accurately, but these things make up a small part of daily activity.

Looking at why these patients were in hospital, more active people had fewer admissions for cancer and diabetes, but surprisingly, there was no difference for heart disease. We suspect that might be due to a gap in the data for heart admissions to private hospitals for a few of the years.
What if everyone got walking?

The difference of 0.29 hospital days per year between the inactive and active people is about a 30% reduction. Does this mean if we could get everyone in the population taking 8,800 steps per day we could shut a third of all hospital beds, and send a third of all doctors and nurses off to practice their golf swing? Unfortunately not.

It turns out our study sample is a rather healthy lot, requiring less hospital care than the average for their age. Compared to our average value of less than one day per year of hospital care, figures from the
Australian Institute of Health and Welfare for 2014-15 show Australians between 55 and 85 years required 14.2 million days of hospital care, or 2.65 bed days per person.
Getting in 40 minutes of walking a day would reap big rewards in overall health.

Whether increasing activity would be of more or less benefit across the whole of the Australian population is unclear. It may be that the general population would have even more to gain from physical activity than our study participants, or it may be that they have serious chronic diseases that make increased activity impossible.

Let’s imagine for a moment that something changes the walking habits of all Australians, so everyone is walking at least 8,800 steps per day – maybe a combination of a Fitbit craze and an oil shortage that sends petrol to A$10 a litre. What effect would this have on health services?

Considering only the people aged over 55, at a minimum it would reduce the need for hospitalisation by 975,000 bed days per year, for a saving of $1.7 billion dollars. Given there are health benefits at other ages, and the less healthy Australians not represented in our study could benefit more, the actual benefit is likely to be even greater.

An extra 4300 steps per day is not much.
It’s just 40 minutes walking, which might include going to the shops, picking up kids, or taking the stairs at work. It doesn’t have to be “exercise”, although higher intensity activity for those who enjoy it has greater health benefits.
With governments searching for ways to reduce spending, and
16% of the federal budget being spent on health, tackling physical inactivity of individual patients, as well as ensuring our urban centres are walking- and cycling-friendly would make a major difference.
