Extend Your Lifespan with Nuts and Seeds

 

Did you know that eating nuts may help extend your life, lower your risk for cardiovascular disease and cancer, help in weight loss and are beneficial in diabetes management?
It’s amazing that such a tiny food possesses such remarkable properties.

Nuts and seeds are such wonderful sources of micronutrients and healthful fats.
You should try to include them in a variety of ways when you prepair a meal.
You can toss a few raw walnuts and flaxseeds in your breakfast cereal and you can add
nuts or seeds to the blender if you make a smoothie;or you can add lightly toasted nuts and seeds to your salads at lunch and dinner; and use nuts to make creamy salad dressings and dips.

Health Benefits Nuts & Seeds
Nuts and seeds are very healthful and versatile, but they are often mislabeled as fattening. They are calorie-dense, so they are not for snacking on. They replace the calories supplied by meats, oils and processed food in your diet and as such they offer well-documented cardiovascular and longevity benefits.

Nuts May Add Years to Your Life
In a study of Seventh Day Adventists, a group whose unique dietary habits have been demonstrated to lower their risk for certain diseases, nut consumption was among a number of lifestyle factors that were found to be associated with their longevity. On average, Adventists live 10 years longer than the average American. In the study, the Adventists who had a high level of physical activity, followed a vegetarian diet, and ate nuts frequently lived an average of eight years longer than those who did not share those habits.
An analysis from the Nurses’ Health Study, including more than 76,000 women, compared multiple lifestyle and dietary factors based on the size of their associations with mortality  risk.
Nut intake and fiber intake were the two dietary factors associated with a lower risk.
The PREDIMED study in Europe, investigating the health effects of a Mediterranean diet, assigned groups to a control low-fat diet, a Mediterranean diet supplemented with olive oil, or a Mediterranean diet supplemented with mixed nuts.
Both Mediterranean groups saw improvements in blood pressure, blood glucose, and cholesterol, and five years later had experienced fewer heart attacks and strokes than the low-fat group.  A very interesting finding in the PREDIMED study was the link between nut consumption and a longer life. The participants who were already eating three or more servings of nuts a week before the study began, and then were assigned to the Mediterranean diet plus nuts group had the lowest risk of death throughout the duration of the study.
Why the link between nuts and longevity? It appears because nuts and seeds have properties that are protective against heart disease, diabetes and even cancer.
Eating five or more servings of nuts per week is estimated to reduce the risk of coronary heart disease by 35 percent. This appears to be at least in part due to prevention of sudden cardiac death and in part due to cholesterol-lowering; other factors that may contribute include improved blood vessel function and reduced inflammation and oxidative stress.
Nuts provoke a minimal glycemic response, which helps to limit blood glucose and insulin after a meal, in turn helping to prevent insulin resistance and diabetes. Almonds, for example, have been found to decrease glycemic and insulin response of a carbohydrate-rich meal while reducing oxidative stress on cells.
There is also substantial evidence that nuts protect against cancer, not just from their own salient features, but also because their fats enhance the absorption of anti-cancer phytochemicals from other foods.

Use Nuts and Seeds to Replace Oil in Salad Dressings
An easy way to include good-for-you raw seeds and nuts in your diet is to replace the processed (no-fiber) empty-calorie oils found in most salad dressings with a nut-based dressing. This allows you to achieve the maximum nutrient value from a salad. In addition to increasing the absorption of nutrients in vegetables, nuts and seeds supply their own spectrum of micronutrients including plant sterols, minerals, and antioxidants. They are also a source of plant protein and fiber. Plus several seeds and nuts (flax, hemp, chia, and walnuts) are rich in omega-3 fatty acids, which are beneficial for brain health. Some seeds—flax, chia and sesame in particular—are rich in lignans, that have been shown to protect against breast and prostate cancer. Replacing olive oil-based dressings with vinegar, fruit and nut-based dressings are definitely the way to go!

Flavonoids

Flavonoids are powerful antioxidants, and sturdy defenders against heart disease and cancer. See also my article titled: Antioxidants in green leafy vegetables
Like carotenoids, flavonoids add color – specifically red, yellow, blue and shades of brown
to the foods we eat and drink.
Present mostly in apples, celery, cocoa, (dark chocolate), cranberries, grapes, broccoli, endive, onions, green and black teas, and red wines.

But experts are beginning to discover that these compounds are doing more.
Some flavonoids make the linings of blood vessels more supple, lowering blood pressure and protecting against a buildup of heart- threatening plague. In one study, grape juice and
chocolate had this effect. Flavovoids also act like Teflon coating for the millions of tiny disks in your blood called platelets. They keep the platelets from clumbing together in the bloodstream and forming clots, which helps prevent heart attacks and stroke.

A recent study at the Harvard Medical School lab has found that one magical flavonoid found in wine and grapes: resveratrol, also lowers blood sugar levels and boosts liver function. In fact, in a group of lucky mice, it increased longevity by 31%.
In one study at the university of Virginia, resveratrol – found in grape skins, raspberries,
mulberries, and peanuts – literally starved cancer cells by interfering with a protein called
nuclear factor-kappa B, that helps food them.

In one Dutch study that examined the eating habits of 800 men, aged between 65 and 84,
researchers found that those who got the least flavonoids in their diets, were 32% more
likely to die from heart attacks than those who ate the most. It didn’t take many flavonoids
to get the benefits. The high-flavonoid group had the equivalent of 4 cops of black tea,
a half cup of apple, and 1//8 cup of onions per day.

When it comes to cancer prevention, flavonoids may help out by influencing cel-signaling
pathways – the way cells turn genes on and off in order to perform thousands of everyday
maintenance activities. Flavonoids may help turn on genes that stop cancer cells from
dividing or invading healthy tissues, or even help activate genes that make cancer cells
commit suicide, say experts from the Linus Pauling Research Institute at Oregon State
University in Corvallis.

In a recent study at the University of California, Los Angeles, those prostate-cancer
survivors who drank 8 ounces of pomegranate juice daily, increased by nearly 4 times
the period during which their PSA levels (prostate specific antigens) a cancer biomaker,
stayed constant. The study even surprised the researchers, who say that the combination
of flavonoids, anti-inflammatory compounds, and antioxidants in pomegranate juice
may be responsible.
