What Is Aging?

Aging is defined as a genetic physiological process associated with morphological and functional changes in cellular and extracellular components aggravated by injury throughout life and resulting in a progressive imbalance of the control regulatory systems of the organism, including hormonal, autocrine, neuroendocrine and immune homeostatic mechanisms.

Aging Process Definition

Aging is the process of growing older; it includes a reduction in strength, endurance, speed of reaction, agility, basal metabolism, sexual activity and hearing acuity. The bones are more brittle, the skin drier and less elastic and the teeth are shed.

The Aging Body

There are several changes which take place in the aging body and most of them are depleting or deteriorating.

Structural Changes For Aging

  • As we age, we lose lean body mass. Reduced muscle mass includes skeletal muscle, smooth muscle and muscle that affects vital organ function, with loss of cardiac muscle perhaps the most important. Cardiac capacity can be reduced and cardiac function impaired by chronic diseases such as atherosclerosis, hypertension or diabetes.
  • Changes occur in the kidneys, lungs and liver, and in ability to generate new protein tissue. Aging can slow the immune system’s response in making antibodies.
  • The loss of lean body mass may be the decrease in basal energy metabolism. To avoid gaining weight, we must reduce calorie intake or increase activity. The goal is energy balance.
  • Reduced body water – 72 percent of total body water is in lean muscle tissue.
  • Total body fat typically increases with age. Fat tends to concentrate in the trunk and as fat deposits around the vital organs. However, in more advanced years, weight often declines.
  • Finally, we lose bone density. After menopause, women tend to lose bone mass at an accelerated rate. There is high incidence of osteoporosis. Aging is a multi factorial biochemical and physiological process that leads to overall cellular breakdown and death.

Aging not only alters our physical appearance due to changes in skin, bones, and muscle tone, but also affects our internal organs.

The heart and immune system become less efficient, and diseases that are rare in young people become increasingly more prevalent in older adults.

Lots of people are looking for the fountain of youth. Believe it or not, the foods you eat may have a big impact on how you age.

Factors That Control Aging

Aging is a natural process and an inevitable facet of life. Every one eventually ages despite the best of efforts and care; however, the manner by which you succumb to age is subjective and tends to vary between individuals.

There are several factors that influence the way you age. Depending on these factors you may age gracefully and be a sight for sore eyes or you may ‘fall from grace’ and be a sore sight for all eyes. Factors that influence aging can be categorized as intrinsic (internal) and extrinsic (external) factors.

Intrinsic Factors For Aging

There are certain factors within you that influence the way you age. You may have little or no control over them.

Genes: Your genes have a mammoth role to play in the manner and rate at which you age! If you belong to a ‘youthful’ family, you too would tend to look young despite your age.

Hormones: Are your hormones all over the place? Just remember that an imbalance in hormones can, without doubt, fast- forward aging.

Cellular inflammation: Aging is also characterized by cellular inflammation which ultimately leads to cell death.

Telomeres:  While discussing genes, it is only appropriate to learn a little about telomeres. They are specialized structures, found at the tail end of chromosomes, that play an undisputed role in cellular Aging. Research has revealed that the size of the telomeres gradually wanes with age. As part of anti aging research, there have been attempts by scientists to reconstruct telomeres. However, studies have shown that such a move could be harmful because the decline of telomeres, with age, is the cell’s defense mechanism against old age diseases, such as cancer.

Extrinsic Factors For Aging

There are several external triggers that influence the way you age. They may be environmental factors or your own lifestyle choices. Let us take a peek-a -boo at a few of them.

Sunlight

The sun sustains life on earth but over exposure to the sun rays speeds up the Aging process. The free radicals produced by the UV rays damages the DNA in skin cells, impair collagen production, destroy elastin and ruin your skin’s ability to regenerate and repair. With time, unappealing changes such as dark spots, dryness and freckles, appear on the skin .The collective harm done by the sun is known as photo damage. Your ability to endure the sun entirely depends on your skin type and the degree of exposure to sunlight. Dark skins, with more melanin, are more sun -tolerant than fair skins; as a result, they tend to age slower.

Excessive Alcohol

It is all very well to enjoy a ‘shot on the rocks’ but remember that alcohol is an established neurotoxin, which speeds up the normal aging process. Excessive alcohol makes a person more vulnerable to various diseases of the heart and liver, and dehydrates the skin, contributing to a dull and aged look.

Stress

Are you the kind of person who worries in a hurry? Beware! A person’s ability to handle stress has a great influence on the way he ages. Oodles of energy is required to deal with stress- causing factors and the rate at which this energy is expended controls the quality of Aging.

Facial Exercises

A few facial exercises which were initially promoted as anti- dote to Aging are now believed to enhance wrinkles and emphasize facial lines

Unhealthy Diet

Look before you eat. If you are on a weight watch just remember that a poor, ill – balanced diet, will rob your skin of its natural sheen. A greasy, jumbo diet can also affect your overall health and usher in premature Aging!

Pollution

If you want to stay youthful for a long, long time stay away from the heat and dust! Pollution produces oxidants on the skin surface, which work on the skin cells and destroys them, thereby fast forwarding the aging process.

Cigarette Smoking

Nicotine breaks down skin cells at a faster pace. As a result, long- time smokers develop wrinkles and a sallow, sagging skin. But the good news is that if the smoker ‘kicks the butt’ the detrimental effects of smoking can be successfully reversed and a visibly improved skin will be there for all to see. Therefore, it is never too late to stop your life from going up in smoke!

Foods to Help Fight the Effects of Aging

Most of us are keen to stay looking as fresh and young as possible, and although there’s no way to pause or turn back the clock, there are few age-proof strategies we can employ to make sure we stay looking good. Maintaining a healthy and well-balanced diet is one approach, and the good thing is that there are some foods that are thought to give us extra ammunition when it comes to combating the signs of aging.

Super food” is an informal term for foods that benefit the body in many different ways. Super foods help to meet several dietary needs and are great sources of essential vitamins and minerals also fight disease and sickness, making them powerful anti-aging tools. Some top anti aging foods are listed below;

Berries

According to the American Chemical Society, Berries are one of the best sources of antioxidants. Plus, they’re rich in fiber and vitamin C to help keep your immune system, joints and skin healthy. They may even help stave off memory loss and cognitive decline. They’re also low in calories with a high water content. All berries have benefits, but blueberries, cranberries, blackberries, raspberries and strawberries have the most antioxidants. Try to choose fresh berries when they’re in season, but unsweetened frozen berries are a good option in the off-season. You can eat berries in a variety of ways: add them as a topping to cereals and salads, toss them into a smoothie before blending or eat them as a sweet snack.

Fish

Fish contains heart-healthy and inflammation-fighting omega-3 fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Eating fish at least once a week may help prevent age-related memory loss. Choose cold-water, fatty fish like salmon, lake trout, herring, sardines and tuna. Try to eat at least two servings of omega-3-rich fish per week. One serving is about 3.5 ounces, or about the size of a deck of cards. Try to replace other meats in your diet with fatty fish, or add canned tuna or salmon to salads instead of chicken or cheese. Stick with fish that has been baked or broiled, not deep-fried.

Olive Oil

Olive oil is rich in monounsaturated fats, which may help lower cholesterol and reduce your risk of heart disease. Choose your oil carefully: Look for a fresh variety of extra virgin olive oil. Do not purchase oil that is more than one year old because the health benefits may diminish over time. Be sure to store it in a cool, dark place. Since it is high in calories, it’s important to use it in moderation. Use olive oil in place of other fatty foods (like butter or stick margarine), not in addition to them. Use it also to make your own salad dressings or lightly coat vegetables to enjoy as a side dish.

Dark Leafy Greens

Dark, leafy green vegetables are loaded with vitamins, minerals and disease-fighting phytochemicals to help protect your skin, vision, heart and brain. The carotenoids in dark, leafy greens may help stop the growth of certain types of cancer cells. Plus, they’re rich in fiber to help keep you feeling full longer and water to keep you hydrated. Kale, collards, turnip greens, Swiss chard, spinach, mustard greens and broccoli are all excellent choices. It’s best to purchase dark, leafy greens fresh, when possible. Look for the ones that have darker green leaves with no yellowing or wilting, and always wash them before eating. There are endless options for adding greens to your diet. Toss them in soups or smoothies, make “green” kale chips or sauté them with spices and seasonings. To help your body absorb all of the nutrients, add one to two teaspoons of olive oil. Note: People who take certain blood thinners may need to avoid eating leafy greens. Talk to your doctor to find out if you fall into this category.

Nuts And Seeds

Nuts and seeds are a good source of heart-healthy monounsaturated fats, plantbased protein, filling fiber, vitamins, nutrients and antioxidants. They may even help reduce the risk of heart disease because the naturally-occurring plant sterols and L-arginine can help lower low-density lipoprotein (LDL) cholesterol levels in the blood and protect the lining of the arteries. Most varieties of nuts are healthy, but walnuts, almonds, pistachios, hazelnuts and pecans are particularly beneficial. But watch out for salted nuts or chocolate-covered nuts; instead, stick with raw, unsalted nuts. For seeds, look for ground flaxseed, soaked chia seeds and hemp seeds. To incorporate them into your diet, add an ounce of chopped nuts or a tablespoon of seeds to your cereal, yogurts, salad or smoothie. You can also eat them as a snack, or have a nut-butter sandwich on whole-grain bread. Remember: They can be high in calories, so practice moderation.

Dark Chocolate

Dark chocolate is rich in powerful antioxidants (flavonoids and polyphenols) linked to reduced inflammation, lower blood pressure and better brain health. These benefits come from dark chocolate only; not milk or white chocolate. The darker the chocolate, the better; look for a bar that is at least 70 percent cocoa. Practice moderation: you only need one to three ounces per day to get benefits. Avoid chocolate that contains added fat, sugar and calories. Don’t replace healthy foods with dark chocolate; instead, switch it out with other treats.

Yogurt

Yogurt is rich in calcium and protein. It may help restore balance in the digestive system via probiotics, prevent high blood pressure16 and keep bones strong and healthy. Choose varieties that are low in sugar, and contain active cultures, probiotics and vitamin D. For more protein, you may want to try Greek yogurt. Yogurt can be eaten for breakfast or as a snack. You may want to add some mix-ins like flaxseed, nuts, granola or berries. You can also blend it into smoothies, or use it as a replacement for sour cream, oil or butter in recipes.

Legumes

Legumes, which include beans, peas and lentils, are packed with complex carbohydrates, fiber, protein and antioxidants. Their high-fiber content may help keep your digestive system healthy, scrub away LDL cholesterol to protect your heart and keep blood sugar levels steady. Reach for a variety of beans (black, kidney, garbanzo, pinto, cannellini, lima, navy, great northern), peas (black-eyed, whole or split) and lentils (green, red, yellow and black). Peanuts are another great option in the legume family. There are many ways to add beans, peas and lentils to your meals. Choose them as a side-dish, or add them to salads, soups and pasta dishes.

Whole Grains

Whole grains are an excellent source of fiber, vitamins (especially B vitamins) and antioxidants. Research from the Journal of Nutrition shows that whole grains may help reduce the risk of heart disease, improve insulin sensitivity, aid in digestion and help with weight maintenance. All whole grains are healthy, but oatmeal, quinoa, barley, cracked-wheat and brown rice are good examples. Shop smart! Look for 100 percent whole wheat or whole grain. Despite their benefits, the average American eats less than one serving of whole grains each day. The USDA recommends at least three to five servings daily. All it takes is some simple swaps: Use whole wheat bread and tortillas instead of the white, refined versions; use wild or brown rice or whole-wheat pasta as a side dish; and start your day off right with oatmeal or whole-grain cereal for breakfast.

Sweet Potatoes

Sweet potatoes contain vitamins A, C and B6, as well as minerals like potassium, magnesium, manganese, calcium and iron. They’re also a great source of vitamin A, which promotes good vision and has anti-aging benefits. Potassium and magnesium help regulate blood pressure. Sweet potatoes come in a variety of colors. The orange and yellow types contain the most vitamin A; the purple and red types are an excellent source of antioxidants. Try to eat sweet potatoes with the skin to get the maximum amount of fiber and nutrients. Trade your traditional white baked potato for a sweet potato. You can also add roasted sweet potatoes to salads.

Garlic

Garlic has anti-oxidant, antiseptic, antibacterial and antiviral properties. While it is used to help treat intestinal, respiratory and skin infections, its most important use is to help reduce high blood pressure, lower levels of harmful blood fats, (LDL cholesterol, triglycerides), reduce blood stickiness, dilate blood vessels and improve peripheral blood flow.

Tomato

Tomatoes are rich in lycopene, which helps prevent cell aging. Lycopene is a powerful anti-oxidant and anti cancer agent that helps to prevent cell aging. Unlike, many vegetables which lose vitamins on boiling, cooking tomatoes, release 5 times more lycopene than is available from raw tomatoes. Increasing research suggest that out of the many types of carotinoids found in food, lycopene is the most beneficial for protection against coronary heart disease and cancer especially the cancer of the lung, rectum and prostate. It is also important for eye health.

More Diet Tips to Help Prevent Disease

  • Eat enough, but not too much. Eating too much leads to weight gain; this strains the heart, blood vessels and joints and accelerates age-related diseases.
  • Eat the smallest meal of the day in the evening. Eating your largest meal early in the day (breakfast or lunchtime) and your smallest meal later (dinnertime) may lead to better digestion, sleep and weight control.
  • Drink plenty of water. Drinking lots of water promotes cleansing, flushes toxins and keeps skin healthy to help people look and feel younger. Staying hydrated also reduces stress on the kidneys and constipation. Talk to your doctor about how much water is right for you.
  • Talk to your doctor about vitamins and supplements. As you get older, it may become challenging to get the right amount of certain nutrients, such as calcium and vitamin D. You doctor may recommend a supplement, depending on your circumstances.
