HeartMath research has demonstrated that different patterns of heart activity (which accompany different emotional states) have distinct effects on cognitive and emotional function. During stress and negative emotions, when the heart rhythm pattern is erratic and disordered, the corresponding pattern of neural signals traveling from the heart to the brain inhibits higher cognitive functions. This limits our ability to think clearly, remember, learn, reason, and make effective decisions. (This helps explain why we may often act impulsively and unwisely when we’re under stress.) The heart’s input to the brain during stressful or negative emotions also has a profound effect on the brain’s emotional processes—actually serving to reinforce the emotional experience of stress.
In contrast, the more ordered and stable pattern of the heart’s input to the brain during positive emotional states has the opposite effect – it facilitates cognitive function and reinforces positive feelings and emotional stability. This means that learning to generate increased heart rhythm coherence, by sustaining positive emotions, not only benefits the entire body, but also profoundly affects how we perceive, think, feel, and perform.
The heart at rest was once thought to operate much like a metronome, faithfully beating out a regular, steady rhythm. Scientists and physicians now know, however, that this is far from the case. Rather than being monotonously regular, the rhythm of a healthy heart-even under resting conditions – is actually surprisingly irregular, with the time interval between consecutive heartbeats constantly changing. This naturally occurring beat-to-beat variation in heart rate is called heart rate variability (HRV).
In general, emotional stress – including emotions such as anger, frustration, and anxiety—gives rise to heart rhythm patterns that appear irregular and erratic: the HRV waveform looks like a series of uneven, jagged peaks (an example is shown in the figure below). Scientists call this an incoherent heart rhythm pattern. Physiologically, this pattern indicates that the signals produced by the two branches of the ANS are out of sync with each other. This can be likened to driving a car with one foot on the gas pedal (the sympathetic nervous system) and the other on the brake (the parasympathetic nervous system) at the same time – this creates a jerky ride, burns more gas, and isn’t great for your car, either! Likewise, the incoherent patterns of physiological activity associated with stressful emotions can cause our body to operate inefficiently, deplete our energy, and produce extra wear and tear on our whole system. This is especially true if stress and negative emotions are prolonged or experienced often.
In contrast, positive emotions send a very different signal throughout our body. When we experience uplifting emotions such as appreciation, joy, care, and love; our heart rhythm pattern becomes highly ordered, looking like a smooth, harmonious wave (an example is shown in the figure below). This is called a coherent heart rhythm pattern. When we are generating a coherent heart rhythm, the activity in the two branches of the ANS is synchronized and the body’s systems operate with increased efficiency and harmony. It’s no wonder that positive emotions feel so good – they actually help our body’s systems synchronize and work better.
Heart rhythm patterns during different emotional states. These graphs show examples of real-time heart rate variability patterns (heart rhythms) recorded from individuals experiencing different emotions. The incoherent heart rhythm pattern shown in the top graph, characterized by its irregular, jagged waveform, is typical of stress and negative emotions such as anger, frustration, and anxiety. The bottom graph shows an example of the coherent heart rhythm pattern that is typically observed when an individual is experiencing a sustained positive emotion, such as appreciation, compassion, or love. The coherent pattern is characterized by its regular, sine-wave-like waveform. It is interesting to note that the overall amount of heart rate variability is actually the same in the two recordings shown above; however, the patterns of the HRV waveforms are clearly different.
Coherence: A State of Optimal Function
The Institute of HeartMath’s research has shown that generating sustained positive emotions facilitates a body-wide shift to a specific, scientifically measurable state. This state is termed psychophysiological coherence, because it is characterized by increased order and harmony in both our psychological (mental and emotional) and physiological (bodily) processes. Psychophysiological coherence is state of optimal function. Research shows that when we activate this state, our physiological systems function more efficiently, we experience greater emotional stability, and we also have increased mental clarity and improved cognitive function. Simply stated, our body and brain work better, we feel better, and we perform better...
The Intelligent Heart
Many of the changes in bodily function that occur during the coherence state revolve around changes in the heart’s pattern of activity. While the heart is certainly a remarkable pump, interestingly, it is only relatively recently in the course of human history—around the past three centuries or so—that the heart’s function has been defined (by Western scientific thought) as only that of pumping blood. Historically, in almost every culture of the world, the heart was ascribed a far more multifaceted role in the human system, being regarded as a source of wisdom, spiritual insight, thought, and emotion. Intriguingly, scientific research over the past several decades has begun to provide evidence that many of these long-surviving associations may well be more than simply metaphorical. These developments have led science to once again to revise and expand its understanding of the heart and the role of this amazing organ.
In the new field of neurocardiology, for example, scientists have discovered that the heart possesses its own intrinsic nervous system—a network of nerves so functionally sophisticated as to earn the description of a “heart brain.” Containing over 40,000 neurons, this “little brain” gives the heart the ability to independently sense, process information, make decisions, and even to demonstrate a type of learning and memory. In essence, it appears that the heart is truly an intelligent system. Research has also revealed that the heart is a hormonal gland, manufacturing and secreting numerous hormones and neurotransmitters that profoundly affect brain and body function. Among the hormones the heart produces is oxytocin—well known as the “love” or “bonding hormone.” Science has only begun to understand the effects of the electromagnetic fields produced by the heart, but there is evidence that the information contained in the heart’s powerful field may play a vital synchronizing role in the human body—and that it may affect others around us as well.

OA Program of Recovery
Overeaters Anonymous offers a program of recovery from compulsive eating using the Twelve Steps and Twelve Traditions of OA. Worldwide meetings and other tools provide a fellowship of experience, strength and hope where members respect one another’s anonymity. OA charges no dues or fees; it is self-supporting through member contributions.
OA is not just about weight loss, weight gain or maintenance, or obesity or diets. It addresses physical, emotional and spiritual well-being. It is not a religious organization and does not promote any particular diet.
OA members differ in many ways, but we are united by our common disease and the solution we have found in the OA program. We practice unity with diversity, and we welcome everyone who wants to stop eating compulsively. Welcome to Overeaters Anonymous. Welcome home.
The main problem with this is your research is presented as only considering a raw VEGAN diet, while it is obvious our ancestors ate a raw OMNIVOROUS diet which was very high in raw ANIMAL foods, which contain large amounts of high energy fats to power our large brains.
Can you please comment on these well known scientific facts:
1. Our ancestors increase in brain size began over 2 million years ago
2. Evidence of the widespread control of fire has only been found going back a hundred thousand years ago
Therefore how can #2 possibly cause #1?
3. Analysis of fossilised humanoid fecal deposits shows that our ancestors have been living on a diet largely composed of raw animal foods for over 2 million years
4. Comparing us against herbivore gorillas and saying we would have to eat for 8 hours a day if we ate raw food ignores the fact we would only need to eat for 15 minutes a day when consuming raw animal foods, due to the high energy content of fat
So since our ancestors were 'living off the fat of the land' and consuming a high energy / high fat diet of raw animal foods there is no need to increase the energy extraction from vegetables by cooking them.
Personally I have found a huge increase in energy and mental alertness by consuming raw animal foods - such as fatty meat and offal - with less food intake.
Let's get this straight. All this Brix issue is, I believe, a question of making the soil nutritious enough for a plant, so that adding manure and adding minerals in the form of powders and mixing it all up with the topsoil around the plants once a year or so should do the trick? I am currently planning on adding a number of fruit-trees to a particular garden because such trees can go for long periods without watering and I can't be there very often. With the ones I've already planted, I've used some sort of high-tech nutrient-rich substance provided by the shop and watered extensively, but that's all so far. Since the soil is likely pretty bad(the garden is terraced all over, after all), I think I could do better. Can one buy powdered minerals like sodium or whatever from gardening centres?

Senior doctors say that “study after study” shows the most widely used class of anti-depressant, called selective seratonin reuptake inhibitors, or SSRIs, cause pregnancy complications including premature birth and pre-eclampsia, which can both be fatal.
Emerging research also suggests SSRIs can double the rate of autism in children, and increase the risk of lung and bowel diseases.
The situation amounts to “a large scale human experiment”, according to Dr Adam Urato, assistant professor of maternal-fetal medicine at Tufts University School of Medicine in Boston, Massachusetts.
Drugs firms were overstating the benefits and underplaying the risks for the sake of profit, he claimed. Family doctors were failing to grasp the true dangers and tell pregnant patients of them, he argued.
He said: “Study after study shows increased rates of newborn complications in those babies who were exposed to SSRIs in-utero. The Federal Drugs Administration [in the US] and Health Canada have put out warnings specifically regarding this issue.”
