Science discoveries in 2015 have cast shade on a vegetable synonymous with good health and have revealed a promising future for the diagnosis and treatment of MS.
A link has been found between autism and GABA, and another between autism and maternal use of SSRIs. Research shows inflammation may cause depression, ovarian cancer screening saves a significant number of lives and the polio virus can battle brain cancer.

Read on for the research that changed how we think about health in 2015.
1) Lettuce: Good for You, Bad for the Earth
Wait, what? Researchers at Carnegie Mellon University found that if Americans actually upped their fruit and veg consumption to the USDA’s recommended daily allowances, energy use would increase 8 percent, water use 10 percent and greenhouse gas emissions would go up 6 percent. (1)
Fruits and veggies require more water and energy per calorie than meat to produce, lettuce being the worst culprit. But calorie for calorie, meat produces the most greenhouse emissions. Despite the high carbon footprint of lettuce, eliminating meat and adopting a vegetarian diet would reduce emissions 33 percent. A vegan diet would reduce emissions by 53 percent. (1)
Now we can even feel guilty about lettuce. For the clearest environmental conscience, grab onions, okra, carrots, broccoli and Brussels sprouts.
2) A New Drug for MS
Multiple sclerosis is a chronic, debilitating autoimmune disease in which the body’s immune system attacks the myelin sheaths that surround neurons.
Ten to 15 percent of MS cases are progressive rather than relapsing. Primary progressive multiple sclerosis occurs later in life and continually worsens, without relapse or remission like other types of MS. (2) Until now, there has been no treatment.
In 2015, Hoffmann–La Roche announced positive results from three large clinical trials of ocrelizumab, medication for both relapsing and progressive MS. Ocrelizumab was shown to be more effective than the top drug currently used to treat relapsing MS. (3)
