Nutrients in Fruits, Vegetables May Help Prevent Breast Cancer

Women with higher levels of micronutrients found in many fruits and vegetables may be less likely to develop breast cancer, a new study finds.

Previous research has shown that the nutrients, called carotenoids, can inhibit tumor growth and reduce the spread of breast cancers.

“Carotenoids are found in carrots, spinach, kale, tomatoes, bell peppers, sweet potatoes and other vegetables,” noted one expert not connected to the study, Dr. Stephanie Bernik.

“There has been some evidence in the past that these substances are helpful in reducing the risk of cancer,” said Bernik, who is chief of surgical oncology at Lenox Hill Hospital in New York City.

In the new study, researchers led by A. Heather Eliassen of Brigham and Women’s Hospital and Harvard Medical School, in Boston, analyzed data from thousands of women who took part in eight previous studies on carotenoid levels and breast cancer.

They found a statistically significant association between higher levels of carotenoids and reduced breast cancer risk, especially so-called ER-negative breast cancers - tumors that aren’t reliant on estrogen to fuel their growth. The findings highlight carotenoid levels as one of the first modifiable risk factors to be identified for ER-negative breast cancers, the team said.

While there is some evidence that carotenoids also inhibit the growth of ER-positive breast cancers (cancers that respond to estrogen), it’s possible that this benefit is hidden by hormone-related associations that overpower other risk factors, the researchers added.

“A diet high in carotenoid-rich fruits and vegetables offers many health benefits, including a possible reduced risk of breast cancer,” they concluded.

 

Bernik agreed. She said the researchers “have shown that there appears to be a real benefit to higher circulating levels of the micronutrients. The present study has more conclusively shown that there probably is some truth to what we tell patients regarding their diets … the foods that your mother always told you are good for you, truly are good for you.”

The study was published Dec. 6 in the Journal of the National Cancer Institute.

The study found a link between carotenoid levels and breast cancer risk, but it did not prove that the nutrients prevent the disease.

Syria ,Iran to Ink MoU to Produce Vaccine for Foot-and-Mouth Disease

TEHRAN (ST)- Syria and Iran and are due to sign a Memorandum of Understanding (MoU) on the production of vaccine for foot-and-mouth disease in Syria.

"Fortunately, we managed to go through the final stages of preparing a draft MoU for launching a site to produce foot-and-mouth disease's vaccine by Iran in Syria and the MoU will be signed by relevant Iranian and Syrian officials tomorrow," Syrian Deputy Agriculture Minister Hussain Salih al-Suleiman said during a visit to Iran's Razi Vaccine and Serum Research Institute in Tehran on Saturday.

According to the MoU, Iran's Razi institute will launch a vaccine production site in Syria to produce 10 million doses of foot-and-mouth vaccine annually, he added.

In recent years, Iran has taken wide strides in science and technology, particularly in medical and medicinal fields.

In 2011, Head of Iran's Pasteur Institute Mostafa Qaneyee had announced that the institute plans to produce human vaccines for rabies and hemophilia diseases.

"The center (Pasteur Institute), in cooperation with its affiliated knowledge-based companies, has started a project to produce rabies and hemophilia human vaccines," Qaneyee told FNA at the time.

Broccoli,Essential Part Of Your Food

 Some people love broccoli and some people hate it, but there's no denying that broccoli is a nutrional wonder.

 Here are 10 reasons why broccoli should be an essential part of your diet.

Nervous System
Broccoli contains a high amount of potassium, which helps maintain a healthy nervous system and optimal brain function, as well as promotes regular muscle growth.

Blood Pressure
Along with a high amount of potassium, Broccoli also contains magnesium and calcium that help regulate blood pressure.

 Vitamin C
  One cup of broccoli contains the RDA of vitamin C, an antioxidant necessary for fighting against free radicals.

   Moreover, vitamin C is an effective antihistamine for easing the discomfort of the common cold.

Bone Health
Broccoli contains high levels of both calcium and vitamin K, both of which are important for bone health and prevention of osteoporosis.

Sun Damage
Broccoli is helpful in repairing skin damage thanks to the glucoraphanin it contains which helps the skin to detoxify and repair itself.

Immune System
One cup of broccoli bolsters the immune system with a large dose of beta-carotene. Trace minerals, such as zinc and selenium, further act to strengthen immune defense actions.

Cancer Prevention
Broccoli contains glucoraphanin, which with the body processes into the anti-cancer compound sulforaphane. This compound rids the body H. pylori, a bacterium found to highly increase the risk of gastric cancer. Furthermore, broccoli contains indole-3-carbinol, a powerful antioxidant compound and anti-carcinogen found to not only hinder the growth of breast, cervical and prostate cancer, but also boosts liver function.

Diet Aid Broccoli is high in fiber, which aids in digestion, prevents constipation, maintains low blood sugar, and curbs overeating. Furthermore, a cup of broccoli has as much protein as a cup of rice or corn with half the calories.

Eye Health
Studies have shown that the carotenoid lutein helps prevent age-related macular degeneration and cataracts, as well as possesses anti-cancer effects. Additionally, broccoli is a good source of vitamin A that is needed to form retinal, the light-absorbing molecule that is essential for both low-light and color vision.

Heart Health
 The carotenoid lutein may also slow down or prevent the thickening of arteries in the human body, thus fighting against heart disease and stoke. The B6 and folate in broccoli also reduce the risk of atherosclerosis, heart attack, and stroke.

Origin of Intelligence and Mental Illness Linked to Ancient Genetic Accident

Researchers have identified the moment in history when the genes that enabled us to think and reason evolved.

This point 500 million years ago provided our ability to learn complex skills, analyze situations and have flexibility in the way in which we think.

Professor Seth Grant, of the University of Edinburgh, who led the research, said: "One of the greatest scientific problems is to explain how intelligence and complex behaviors arose during evolution."

The research, which is detailed in two papers in Nature Neuroscience, also shows a direct link between the evolution of behaviour and the origins of brain diseases.

Scientists believe that the same genes that improved our mental capacity are also responsible for a number of brain disorders.

"This ground breaking work has implications for how we understand the emergence of psychiatric disorders and will offer new avenues for the development of new treatments," said John Williams, Head of Neuroscience and Mental Health at the Wellcome Trust, one of the study funders.

The study shows that intelligence in humans developed as the result of an increase in the number of brain genes in our evolutionary ancestors.

The researchers suggest that a simple invertebrate animal living in the sea 500 million years ago experienced a 'genetic accident', which resulted in extra copies of these genes being made.

This animal's descendants benefited from these extra genes, leading to behaviorally sophisticated vertebrates -- including humans.

The research team studied the mental abilities of mice and humans, using comparative tasks that involved identifying objects on touch-screen computers.

Researchers then combined results of these behavioral tests with information from the genetic codes of various species to work out when different behaviours evolved.

They found that higher mental functions in humans and mice were controlled by the same genes.

The study also showed that when these genes were mutated or damaged, they impaired higher mental functions.

"Our work shows that the price of higher intelligence and more complex behaviours is more mental illness," said Professor Grant.

The researchers had previously shown that more than 100 childhood and adult brain diseases are caused by gene mutations.

"We can now apply genetics and behavioural testing to help patients with these diseases," said Dr Tim Bussey from Cambridge University, which was also involved in the study.

Olive Oil's Benefits On Skin Health

Olive oil is one of the most sought after natural oils for skin care. In fact, olive oil has been used as an ancient remedy for skin care during the Egyptian civilization and it is still widely used today. Everything from, stretch mark therapy, acne therapy and anti-aging therapy have been used for a long time. The general population will most likely use olive oil as a food condiment .

The most expensive olive oil product is usually labeled as “extra virgin” or “cold pressed”. This is because extra virgin olive oil is extracted from the first pressing of olives. It is not processed and it is the purest of olive oil extract. So if you are buying any bottle of extra virgin olive oil for cooking, you’ll be pleased to know that it is the healthiest type of oil for cooking. Even skin products labeled as “extra virgin” are more expensive, have more nutritional compounds for skin health and are far better at helping to improve the appearance of your skin.

Anti-inflammatory Properties

There are a variety of antioxidants in olive oil including Vitamin A and E but the most potent compound is hydroxytyrosol. Hydroxytyrosol is a very rare but potent antioxidant found in olive oil that prevents free radical damage on skin cells. This compound also absorbs deeply into the skin and is suitable for all skin types. For this reason, olive oil has very potent anti-inflammatory properties and used in a variety of products

Moisturizing Properties

As explained earlier, olive oil is abundant in antioxidants. These antioxidants work really well as moisturizers. One of the main reasons why olive oil works really well as a moisturizer is the hydrophilic properties of these antioxidants which allow it to form a protective barrier trapping moisture on your skin. Lots of skin products used various synthetic chemical that do moisturizer but they clog your pores and are carcinogenic in some cases. For this reason, olive oil can be applied on your face. In addition to that, its deep penetrating properties not only moisturize your skin but also help brighten your skin.

To use olive oil on your face, just follow these simple steps:

  • Wash your face with water thoroughly.
  • Apply a layer of olive oil moisturizer on your face just before you go to sleep.

Alternatively, you can create a moisturizing face mask with olive oil, honey and egg. Leave it on your face for 15 minutes daily. You will begin to see results even after a few days of application. If you are not sure how to make face mask, there are plenty of methods to make your face mask

Skin Exfoliator

Olive oil helps remove clogged pores and dead skin cells. But why use olive oil? One of the main reasons is because it does not clog pores. The other reason is because it smoothens your skin texture and softens your skin due to its intrinsic antioxidant properties. all

Just mix a little bit of olive oil and sea salt on your palm. Use extra virgin olive oil for best results. Rub it evenly and then apply it over dry skin to remove dead skin cell layers. If you don’t want to use sea salt you can opt to use sugar as well in the mixture. It is best to use salt and olive oil mixture on your face. Sugar and olive oil mixture is best used on the body.

This will allow healthier and younger skin to grow upwards and replace dead skin. Do this every week and you will be on your way to healthier and younger looking skin.

This method is best done at night before bed. If your skin feels dry after cleansing, use a drop of oil mix and massage into dry areas.
