How Some Healthy Foods Can Be Bad For The Environment

Vegetarians,put down your pitchforks. Meat-eaters, less of the smug grin. Yes, this article is about some of the environmental issues associated with vegetable-rich diets within the U.S., but it is not an attack on the ethics-drivendietary choices of people and it shouldnt be used as such.

A new study has looked at what would happen if the entire U.S.populationfollowed exactlythe dietary guidelines from the Department of Agriculture(USDA). The team modeledthree different scenarios: a reduction in calories consumed but no changes in diet;a shift to a more vegetable-heavy diet but no caloric reduction;and a mix of the two, which is the one recommended by the USDA.

The study, which is published inEnvironment Systems and Decisions, aims to highlight how complicated it is to balance environmental issues and human needs.

The researchersinvestigated three parameters for thescenarios: energy use for food production, blue water footprint (the amount of freshwater necessary to produce a product), and greenhouse gas (GHG) emissions. In scenario 1,quantities of these variables were reduced by about nine percent, which is unsurprising since the only change was the consumption of fewer calories.

The diets in scenario 2 and 3 have more fish, vegetables, and fruit compared to the average U.S. diet. The higher intake of these healthy foods is balanced by a reduction in meat, solid fats, and added sugars. While this diet is good news for our bodies, as evidenced by the many benefits thought to be offered by the famous Mediterranean diet,the study suggests it might not be so good for the environment.

All three parameters actually increased under scenarios 2 and 3. For scenario 3, energy use went up by 38 percent, water use by 10 percent, and greenhouse gas emissions by six percent. Scenario 2 was found to beeven worse. But why is that?Per Calorie, production of vegetables requires more energy and water than meat, but generates only one-quarter of GHG emissions compared to beef.

Also, the study investigated a vegetarian diet, not a vegan one. “Dairy, by far, has the greatest impact on increased GHGemissions because it has the third highest emissionsintensity value, which is then compounded by USDA recommendationsfor substantial increases in dairy,” wrote the authors in thepaper.

Theres a complex relationship between diet and the environment, Michelle Tom, a Ph.D. student at Carnegie Mellon University and lead author on the paper, said in a statement. What is good for us health-wise isnt always whats best for the environment. Thats important for public officials to know and for them to be cognizant of these tradeoffs as they develop or continue to develop dietary guidelines in the future.

Another food grouprecommended by the USDA guidelines is fish.Fish has a tiny blue water footprint, as most of the fish that reachour tables come from the ocean, but this advantage is offset by high energy demands. Fisheries often need to move far from the shore, requiring significant amounts of fuel for transport and creating GHG emissions along the way.

This study is not universal, though. Its specific to the U.S., so dietary requirements, infrastructure, andcurrenteatinghabitsneed to be taken into account when makinggeneral conclusions about vegetable-rich diets. A similar dietary guideline inEuropewould actually reduce energy use, blue water footprint,and GHG emissions, largely due to the fact that food is often produced more locally.

The researchers also looked at how the parameters changefor the three scenarios based on food waste.Between 34 and 42 percent of food produced is wasted every year. The paper shows that if we could significantly reduce the amount of wasted food, our impact on the environment wouldbe drastically reduced no matter our diet. Last week, for example, Francepassed a very strict lawto fightfood waste, an important step toward a global culture of sustainable food production.

Paschimottanasana Yoga For Blood Pressure In Tamil

இரத்த அழுத்தம் Paschimottanasana யோகா
Sit on the floor with your buttocks supported on a folded blanket and your legs straight in front of you. Press actively through your heels. Rock slightly onto your left buttock, and pull your right sitting bone away from the heel with your right hand. Repeat on the other side. Turn the top thighs in slightly and press them down into the floor. Press through your palms or finger tips on the floor beside your hips and lift the top of the sternum toward the ceiling as the top thighs descend.

Draw the inner groins deep into the pelvis. Inhale, and keeping the front torso long, lean forward from the hip joints, not the waist. Lengthen the tailbone away from the back of your pelvis. If possible take the sides of the feet with your hands, thumbs on the soles, elbows fully extended; if this isn't possible, loop a strap around the foot soles, and hold the strap firmly. Be sure your elbows are straight, not bent.

When you are ready to go further, don't forcefully pull yourself into the forward bend, whether your hands are on the feet or holding the strap. Always lengthen the front torso into the pose, keeping your head raised. If you are holding the feet, bend the elbows out to the sides and lift them away from the floor; if holding the strap, lighten your grip and walk the hands forward, keeping the arms long. The lower belly should touch the thighs first, then the upper belly, then the ribs, and the head last.

With each inhalation, lift and lengthen the front torso just slightly; with each exhalation release a little more fully into the forward bend. In this way the torso oscillates and lengthens almost imperceptibly with the breath. Eventually you may be able to stretch the arms out beyond the feet on the floor.

Yoga For Blood Pressure – Managing Hypertension and Treatment In Tamil

Reduce high blood pressure with simple yoga techniques as follow –
You are able to control your breathing much better as breathing very fast is one of the major problems of an asthma patient. Although you are breathing fast, the oxygen is not being absorbed in your body. Practicing slow breathing would not only improve your breathing but also allow you to control it better.

Asthma patients tend to hold their breath for long in an attempt to get more oxygen out of the air that they have inhaled. This can aggravate the condition as this puts more pressure on your internal organs. You are able to take breathe from the diaphragm which helps you in getting used to taking deep and more relaxed breaths.
The severity of an asthma attack, if and when it happens, can be significantly reduced if you have been practicing Yoga. Although one should never make the mistake of ignoring asthma medication, Yoga can help to calm and de-stress your body and prevent the severe impact of an asthma trigger. Moreover, if you get an asthma attack, the practice of slow breathing would help you survive the complication posed by constricted airways much better.
A functional advantage of yoga is having control over your nervous reflexes. This facilitates you to lessen the excessive movement of the parasympathetic nerves.
Benefits of yoga and its asanas can be varied. They not only help in calming down the stressed muscles in your chest, so that you can breathe more effortlessly but they also discharge the energy blocks. Overturned asanas also deplete mucus from your lungs.
