What is better than canned tuna?

OUR WINNER: Fresh Tuna! Virtually every type of fresh, smoked or canned oily fish counts, except for canned tuna. This is because most fish is processed in the can from raw, whereas tuna is cooked prior to canning. This significantly reduces the levels of long-chain omega-3 fatty acids.

Tuna is an excellent source of lean protein and buying canned tuna is a cost-effective and convenient way to get our weekly portion of oily fish, or so we think. Is canned tuna as good as fresh tuna?

Let’s look at some stats:

FRESH TUNA CANNED TUNA Serving size 100g, Bluefin (Wild), raw 100g, light, canned in water, no added salt, drained solids Calories 144Kcal 116Kcal Protein 23.3g 25.5g Carbohydrates 0 g 0g Fat 4.9g 0.8g Saturated fat 1.3g 0.2g Omega-3 Fatty Acids 1,298mg 279mg Sodium 39mg 82mg Vitamin A 2,183IU 56IU Niacin (B3) 8.7mg 13.3mg Vitamin B12 9.4mcg 3mcg Selenium 36.5mcg 80.4mcg

Here are some highlights:

Both are low in saturated fat and sodium.

Both are very good sources of protein, vitamins B3 and B12 and selenium. Selenium acts as an antioxidant, scavenging free radicals that can damage cells and contribute to cardiovascular disease, cancer and cognitive decline. Fresh Bluefin tuna is also an excellent source of vitamin A. Bluefin tuna is rich in omega-3 fatty acids, which may help prevent heart disease. Omega-3 fatty acids are also important for women who are pregnant or breastfeeding because they can help a baby’s nervous system to develop.

OUR WINNER: Fresh Tuna!

We have to hand it to fresh tuna for its higher levels of omega-3 fatty acids. The official recommendation is that we should eat two portions of fish a week, of which one portion should be oily. Oily fish is rich in omega-3 fatty acids which help to thin the blood, reduce inflammation and aid brain function. Virtually every type of fresh, smoked or canned oily fish counts, except for canned tuna. This is because most fish is processed in the can from raw, whereas tuna is cooked prior to canning. This significantly reduces the levels of long-chain omega-3 fatty acids. Nevertheless, canned tuna is still a healthy high protein food and has the advantage of being relatively inexpensive and convenient. So make sure to include both fresh and canned tuna as part of a healthy diet. Buy canned tuna in spring water rather than brine, though, to keep salt intake down. Also, tuna that is canned in oil is higher in fat and calories. One word of caution though: if you are trying for a baby or are pregnant, you should have no more than four cans of tuna a week. This is because tuna contains high levels of mercury, which accumulate in the body and can affect the development of a baby in the womb. If you are breastfeeding, however, there is no limit on how much canned tuna you can eat. Also, due to the higher levels of mercury in tuna, if you are eating canned tuna, it is best not to pick fresh tuna as your weekly portion of oily fish. Other fish high in omega-3 fatty acids you could try instead include salmon, mackerel and sardines.

Is there an app to see inside clothes?

SpyGlass

At first it may not sound morally correct, but an Android app developed by Ezel Software enables Android-powered smartphone owners to see through some thin fabrics. Appropriately named, the application works on Android 2.2 or higher as the earlier builds did not support video data from the camera to be altered in real time. However, there is hope for iPhone users as well since compatibility with other devices is being tested by the developer.The way SpyGlass works is not exactly rocket science, but it required quite some time to be spent fine tuning. When the rear facing camera on the smartphone is activated, SpyGlass amplifies the infrared spectrum of light, which you cannot normally see, and blends it with the visible video feed. Since infrared light has a longer wavelength, it can easily pass through finer fabrics, after which it gets reflected back by the skin just like visible sunlight.Several countries, among which Portugal, Greece, and Italy, are already considering banning SpyGlass from being used because of the moral issues that it brings up, especially when the summer months are right around the corner. We suggest that you give it a try while it is still available for download – link to the app has been posted for you below. Use it responsibly!source: Ezel Download link: Here
