The study assessed the blood concentrations of nine antioxidants - including carotenoids, which are a class of antioxidants mostly found in orange-colored produce - in 1,000 male and female participants between the ages of 25 and 74. During the assessment, the participants completed a questionnaire about their attitudes on life.
The scientists found that the most optimistic participants each had up to a 13 percent increase in blood concentrations of carotenoids compared to those who were less optimistic. Moreover, the scientists also found that the participants who consumed fewer than three servings of fruits and vegetables per day were considerably less optimistic than those who consumed more than three servings per day.
"Individuals with greater optimism tended to have greater levels of carotenoids such as beta-carotene," said the study's lead investigator, Julia Boehm. "This is the first study of its kind to report a relationship between optimism and healthier levels of carotenoid concentrations."
Avocado is super food.
Calories are irrelevant if they're nutritionally packed. It's nutritionally empty calories that lead to obesity. Avocados contain good fats that are necessary for building nervous system and brain tissue and curbing cardiovascular tissue inflammation that leads to clogged arteries.
Good fats include Omega-3 fatty acids that health conscious folks scramble to acquire from fish oils and flax seeds. There are plenty of Omega-3s in an avocado. There's also an abundance of oleic acid for Omega-6 fatty acids, which if unprocessed and not out of balance with Omega-3s support heart health. Cold pressed pure olive oil is an oleic acid provider also.
There's also a considerable amount of protein in an avocado. It's provided in a bundle of all the amino acids needed for complete proteins. This means your pancreas doesn't need to work so hard providing enzymes appropriate for digesting meat whole proteins instead of seeking and destroying cancer cells.
Avocados also provide several carotenoids and flavonoids, such as beta-carotene, alpha-carotene, lutein, lycopene, zeaxanthin and others. They all promote heart and eye health as well as protect you from neuro-degenerative diseases. You'll also get a healthy dose of natural vitamin E and magnesium.
