Climate changemitigation policies tend to focus on the energy sector, while the livestock sector receives surprisingly little attention, despite the fact that it accounts for 18% of the greenhouse gas emissions and for 80% of total anthropogenic land use. From a dietary perspective, new insights in the adverse health effects of beef and pork have lead to a revision of meat consumption recommendations. Here,we explored the potential impact of dietary changes on achieving ambitious climate stabilization levels.

Injury to the skin of five food
Posted by aboutchina on May 7th, 2010
Some people are willing to spend a fortune for skin creams that promise to rejuvenate aging skin, but give little thought to the role that diet plays. Just as there are foods that enhance skin health, such as fresh fruits and vegetables, there are ones that can harm skin and increase the risk of skin laxity and wrinkling. Isn’t it time to take a closer look at the foods you’re eating? Here are some dietary habits that can harm skin health.
Eating High Carb, Processed Foods
High carb, processed foods such as white bread, white potatoes, white rice, and sugary desserts not only destroy the waistline, but also harm the skin. A carb rich diet causes rapid elevation of blood sugars which promotes glycation where sugar molecules bind to a protein such as skin collagen and damage it. When skin collagen is damaged, it leads to skin wrinkles and sagging. How to prevent this undesirable sequence of events? Substitute processed carbs with whole grains whenever possible.来源：www.examda.com
Drinking Alcohol
Alcohol harms skin in a variety of ways. By dilating blood vessels, it aggravates the condition known as rosacea, causing worsening of the characteristic redness and flushing. Alcohol is also associated with the formation of telangiectasias – those ugly, red spider veins that form on the face and body. Alcohol is dehydrating to the skin, leading to excess moisture loss which can increase skin dryness. It also increases inflammation which can damage collagen and elastin leading to skin wrinkling and sagging.
Excessive Salt
Too much salt in the diet harms skin appearance in the short term by causing undereye puffiness and swelling, as fluid collects in the tissues around the eyes and face. Reducing sodium in the diet and getting more potassium rich foods can help to reduce puffy eyes. Drinking more water also helps to flush out excess sodium.
Not Choosing Protein Wisely
A diet rich in red meat induces inflammation which can be damaging to skin collagen. Eating fatty fish high in omega-3’s has the opposite effect. Omega-3’s are
These foods you can’t forget

Some foods just aren’t taken seriously. Consider celery, for example—forever the garnish, never the main meal. You might even downgrade it to bar fare, since the only stalks most guys eat are served alongside hot wings or immersed in a Bloody Mary.
All of which is a shame, really. That’s because besides being a perfect vehicle for peanut butter, this vegetable contains bone-beneficial silicon and cancer-fighting phenolic acids. And that’s not even what makes celery so good for you.
Eat This, Not That! has rounded up six of the most underappreciated and undereaten foods that can instantly improve your diet. Make a place for them on your plate, and you’ll gain a whole new respect for the health benefits they bestow—from lowering blood pressure to fighting belly fat. And the best part? You’ll discover just how delicious health food can be.
Celery
Per large stalk:
* 10 calories
* 0 g fat (0 g saturated)
* 51 mg sodium
* 1 g fiber
This water-loaded vegetable has a rep for being all crunch and no nutrition. But ditch that mindset: Celery contains stealth nutrients that heal.
Why it’s healthy
“My patients who eat four sticks of celery a day have seen modest reductions in their blood pressure—about 6 points systolic and 3 points diastolic,” says Mark Houston, M.D., director of the Hypertension Institute at St. Thomas Hospital, in Nashville. It’s possible that phytochemicals in celery called phthalides are responsible for this health boon, since these compounds relax muscle tissue in artery walls and increase bloodflow, according to nutritionist Jonny Bowden, Ph.D., author of The 150 Healthiest Foods on Earth. And beyond the benefits to your BP, celery also fills you up with almost no calories.
Seaweed
Per Tbsp, dried:
* 20 calories
* 1 g fat (0 g saturated)
* 73 mg sodium
* 4 g protein
While this algae is a popular health food in Japan, it rarely makes it into U.S. homes.
Why it’s healthy
There are four classes of seaweeds—green, brown, red, and bluegreen—and they’re all packedwith healthful nutrients. “Seaweeds are a great plant source of calcium,” says nutritionist Alan Aragon, M.S. They’re also loaded with potassium, which is essential for maintaining healthy blood pressure levels. “Low potassium and high sodium i
