Fat and oil enhance benefits of vegetables

A spoonful of oil makes vegetables more nutritious, eating salad with added fat in the form of soybean oil promotes the absorption of different micronutrients that promote human health. Conversely, eating the same salad without the added oil reduces the amount of absorb nutrients in the body.

Added oil aided in the absorption of seven different micronutrients in salad vegetables. Those nutrients include four carotenoids – alpha and beta carotene, lutein and lycopene – two forms of vitamin E and vitamin K. The oil also promoted the absorption of vitamin A, the eighth micronutrient tracked in the study, which formed in the intestine from the alpha and beta carotene.

The amount of oil added to the vegetables had a proportional relationship with the amount of nutrient absorption. That is, more oil means more absorption. Researchers examined women who consumed salads with various levels of soybean oil.

The subjects then had their blood tested to measure the absorption of nutrients. Women were chosen for the trial due to differences in the speed with which men and women metabolize the nutrients in question. The results showed maximal nutrient absorption occurred at around 32 grams of oil.
So a spoonful or two of salad dressing may indeed help you derive the optimal nutritional benefit from your vegetables.

Foods for healthy heart

Lutein is a xantrophyll-  yellow pigments from the carotenoid family, it is present in brightly coloured vegetables and fruit like yellow and red peppers, kale, carrots, broccoli and spinach. It can reduce risk of cardiovascular disease.

Poor diet increases inflammatory processes in the body. Inflammation is a major factor in many types of coronary artery disease, such as myocardial infarction, lutein has ability to protect tissues from oxidative stress and inflammation.

Regular intake of healthy diet can reduce risk of developing cardiovascular heart disease. High blood concentrations of lutein can reduce coronary heart disease, stroke, and metabolic syndrome.

Lutein is absorbed and stored by the cells of the immune system in the blood.
The higher the level of lutein in the blood, the lower the level of inflammation in the body. Lutein treatment lowers the inflammatory activity of the cells.

Lutein in broccoli can boosts children's IQ

Lutein is a carotenoid vitamin. It is related to beta-carotene and vitamin A.
Foods rich in this substance are broccoli, spinach, kale, egg yolk, corn, orange, pepper, kiwi fruit and grape.

The compound reverse fading memory.
High levels of lutein boosts children performance and improve their IQ.
Researchers asked children to do a cognitive task, those with higher levels of the substance did better on the task and didn't have a brain spike during the activity.

Researchers discovered that children with higher lutein levels are better in academic tests than those with lower levels. Lutein is a key factor in measuring a child's cognitive development.

It concentrates in the brain, prevents brain spike and protects the memory. It can prevents the inception of Alzheimer’s diseases.
