Health Benefits of Eating Tomatoes Emerge
ScienceDaily (Mar. 7, 2011) — Eating
more tomatoes and tomato products can make people healthier and decrease the
risk of conditions such as cancer, osteoporosis and
cardiovascular disease, according to a review article the American
Journal of Lifestyle Medicine (published by SAGE).
The researchers found that tomatoes are the biggest source of
dietary lycopene; a powerful antioxidant that,
unlike nutrients in most fresh fruits and vegetables, has even greater bioavailability after cooking and processing. Tomatoes
also contain other protective mechanisms, such as antithrombotic and anti-inflammatory functions.
Research has additionally found a relationship between eating tomatoes and a
lower risk of certain cancers as well as other conditions, including cardiovascular disease, osteoporosis, ultraviolet
light-induced skin damage, and cognitive dysfunction.
Eating Apples
Extends Lifespan of Test Animals by 10 Percent
ScienceDaily (Mar. 8, 2011) — Scientists are reporting the
first evidence that consumption of a healthful
antioxidant substance in apples extends the average lifespan of test
animals, and does so by 10 percent.
Zhen-Yu Chen and colleagues note that damaging substances
generated in the body, termed free radicals,
cause undesirable changes believed to be involved in the aging process and some diseases. Substances known as
antioxidants can combat this damage. Fruits and
vegetables in the diet, especially brightly colored foods like tomatoes,
broccoli, blueberries, and apples are excellent sources of antioxidants.
Exercise Can
Curb Marijuana Use and Cravings, Study
Finds
ScienceDaily (Mar. 8, 2011) —
Vanderbilt researchers are studying heavy users of marijuana to help understand
what exercise does for the brain,
contributing to a field of research that uses exercise as a modality for prevention and treatment.
It is the
first study to demonstrate that
exercise can reduce
cannabis use in persons who don't want to stop.
During the study
their craving for and use of cannabis was
cut by
more than 50 percent after exercising on a treadmill for
10 30-minute sessions over a two-week period.
There is no way currently to treat cannabis dependence with
medication,
"It shows that exercise can really
change the way the brain works and the way the
brain responds to the world around us," he said. "And this is vital to health
and has implications for all of medicine."

Mediterranean
Diet: A Heart-Healthy Plan for Life
ScienceDaily (Mar. 9, 2011) — The
Mediterranean diet has proven beneficial effects not only regarding metabolic
syndrome, but also on its individual components including waist circumference, HDL-cholesterol levels, triglycerides
levels, blood pressure levels and glucose metabolism, according to a new
study published in the March 15, 2011, issue of the Journal of the American
College of Cardiology. The study is a meta-analysis, including results of 50
studies on the Mediterranean diet, with an overall studied population of about
half a million subjects.
The Mediterranean diet is a dietary pattern characterized by high consumption of monounsaturated fatty acids, primarily from olives and
olive oils; daily consumption of fruits, vegetables, whole grain
cereals, and low-fat dairy products; weekly consumption of fish, poultry, tree nuts, and legumes; a relatively
low consumption of red
meat; and a moderate daily consumption of
alcohol, normally with meals.

Mucha carne, demasiadas grasas y un
exceso de bebidas refrescantes. Así, desequilibrada, es la dieta diaria de
los españoles, que prefieren comer un buen filete de carne roja que un
plato de verduras a la plancha. En España no se come en exceso (2.482
kilocalorías por persona y día de media), pero sí mal.

Cinco claves para
evitar el cáncer de colon
Es el cáncer más frecuente y el más
mortal. Cada año se diagnostican en España 25.000 nuevos tumores de colon
y recto (500 nuevos casos diagnosticados semanalmente) muchos con mal
pronóstico porque no se detectan a tiempo. Y fallecen cerca de 14.000
personas (250 fallecimientos por este tumor cada semana).
Un estudio ha encontrado una fuerte
relación entre el consumo de bebidas
alcohólicas, el exceso de peso y la
posibilidad de desarrollar el cáncer y, en concreto el de
colon.
Adiós al tabaco
El informe del World Cancer Research Fund
también señala a la carne roja como una de
las causas más probables de la aparición del cáncer de colon
