0.03 -> many people believe that fish are a
2.07 -> healthy food they provide a mega three
4.23 -> fats and that perhaps fishing isn't as
6.06 -> cruel as factory farming or doesn't
8.069 -> cause as much environmental damage let's
10.349 -> look at what the science and evidence
11.79 -> has to say about this
13.29 -> [Music]
15.47 -> the reason some fish are promoted as a
18.119 -> health food is that they contain more
20.189 -> omega-3 fats than any other species you
23.1 -> may have heard these being called oily
25.109 -> fish and these include mackerel salmon
27.21 -> and sardines other fish such as Cod
29.4 -> store omega-3s mainly in their liver
31.619 -> which is why omega-3 supplements use cod
34.14 -> liver oil we need a mega three fats for
36.57 -> our cell membranes brain and nervous
38.61 -> system they also play a role in blood
40.92 -> pressure regulation blood clotting and
42.629 -> have anti-inflammatory properties and
44.82 -> because we cannot make them ourselves we
46.35 -> must get them from our food fish contain
48.78 -> two types of omega-3s
50.129 -> they're called EPA and DHA the only
53.76 -> reason fish contain these is because
55.26 -> they eat microalgae producing these fats
57.239 -> and then store them in their tissues the
59.609 -> long-held belief is that fish oil may
61.289 -> help protect us from heart disease and
63.51 -> stroke but now research shows that
65.76 -> eating oily fish or fish oil doesn't
68.189 -> offer any advantage when it comes to
70.02 -> heart health as a highly respected
72.21 -> Cochrane review put it moderate and
73.92 -> high-quality evidence suggests that
75.81 -> increasing epa and DHA has little to no
78.57 -> effect on mortality or cardiovascular
80.939 -> health as a previous review essentially
83.729 -> suggested the same the authors also
85.74 -> pointed out at getting our Omega threes
87.689 -> directly from microalgae is a better
89.7 -> alternative as it reduces overfishing
91.67 -> environmental pollution and doesn't
93.72 -> expose us to toxins in the fish the good
96.119 -> news is that there are plenty of algae
98.369 -> based omega-3 supplements and if you'd
100.5 -> rather source your omega-3s from plants
102.21 -> there's more good news a plant based
104.549 -> omega-3 fat called ala has been shown to
106.89 -> decrease the risk of fatal heart disease
108.72 -> you can get plenty of ala from flax
110.43 -> seeds chia seeds hemp seeds walnuts and
112.92 -> rapeseed oil the bottom line is Omega
115.229 -> threes are essential but getting them
117.09 -> from fish is neither necessary nor is it
119.7 -> good for you
122.619 -> both freshwater and ocean fish live in
125.63 -> waters polluted by industrial and
127.34 -> agricultural residues drugs water
129.979 -> products and similar nasty substances
132.08 -> fish naturally accumulate heavy metals
134.569 -> such as mercury cadmium lead and
136.55 -> pesticide residues in their fatty
138.2 -> tissues and that's why we're being
140.269 -> warned against eating too much fish as a
143.09 -> vague precaution pregnant women and
144.739 -> small children are told not to eat more
146.48 -> than two servings of oli fish a week but
149.03 -> that's not all they are also told to
151.519 -> avoid eating shark swordfish or Marlin
153.769 -> because these accumulate more mercury
155.84 -> and their consumption could damage a
157.549 -> developing baby's nervous system the
159.47 -> toxic cocktail fish contain can cause a
162.079 -> range of serious health issues from
164.209 -> nerve damage to impaired vision and
165.95 -> liver damage just to illustrate that no
168.11 -> matter where in the world you go the
169.579 -> issue remains the same here are some
171.53 -> recent studies one from the United
173.959 -> States shows that both locals and
175.549 -> newcomers face serious issues resulting
177.62 -> from fish consumption another from South
180.319 -> America states how nobody really knows
182.42 -> what's in the fish they got caught in
184.76 -> their waters and then there's the Waring
186.92 -> study from Italy about pesticide
188.48 -> residues and heavy metals
193.2 -> shellfish accumulate pollutants as well
195.78 -> as fish do but because shellfish are
197.64 -> bottom feeders a lot of stuff you may
199.26 -> not want to eat ends up in their flesh
200.94 -> and organs on top of that they don't
203.31 -> expel waste as well as other animals do
205.59 -> so by eating them you eat their own
207.84 -> feces too and if that isn't exactly
210.36 -> appetizing add to it that most shellfish
212.88 -> and oysters in particular are
214.14 -> contaminated with norovirus yes that's
216.75 -> the vomiting diarrhea inducing bug a
218.97 -> recent survey found that 69% of oysters
222.12 -> carried norovirus and if you're
224.28 -> wondering why shellfish are so
225.989 -> contaminated another study has a clear
228.63 -> answer
229.41 -> so human waste is polluting the waters
231.54 -> where shellfish live they're inevitably
233.34 -> eating some of it get infected with the
235.23 -> virus and give it back to us when we eat
237.69 -> [Music]
241.39 -> hepatitis E is a virus targeting the
244.34 -> liver if you get infected it can cause
246.769 -> fever fatigue nausea joint pain and
249.799 -> yellow tinted skin and eyes it's not
251.84 -> very common in developed countries but
253.4 -> outbreaks do happen and they're often
255.17 -> linked to the consumption of
256.28 -> contaminated shellfish this study
258.169 -> illustrates the situation really well
263.86 -> commercial fishing decimates the oceans
266.33 -> and most fish populations are now
267.949 -> collapsing the official figures say that
270.32 -> 90% of fish stocks are depleted
272.419 -> discarded nets and fishing gear are also
274.639 -> one of the main plastic pollutants in
276.26 -> the oceans accounting for 46 percent of
278.75 -> all plastic trash in the seas and
280.4 -> killing more and more sea life that gets
282.59 -> entangled in the nets and fish farms are
285.62 -> not the answer either about 50% to fish
288.26 -> contaminated worldwide comes from farms
290.24 -> that hold huge number of fish in
292.25 -> close-quarters diseases and fish
294.77 -> parasites are thriving in these
296.33 -> environments so the overuse of
297.68 -> antibiotics antiparasitics and
299.72 -> pesticides thrown in the water as a cure
301.58 -> is mind-blowing but that's not where it
304.07 -> ends
304.43 -> fish farms also increase the pressure on
306.53 -> wild fish populations whichever way we
309.47 -> look at it eating fish is far from
311.57 -> harmless
312.08 -> it's neither healthy nor sustainable and
314.72 -> it hurts to fish do feel pain and
317.24 -> research has also revealed they're
319.039 -> extremely sensitive to pressure so any
321.229 -> kind of fishing subjects them to
322.76 -> suffering in multiple ways it's time to
325.31 -> leave fish in the water and get our mega
327.139 -> threes from flaxseed Chia and hemp seeds
329.599 -> walnuts rapeseed oil all algae
332.419 -> supplements it turns out it's not just a
334.789 -> more ethical and sustainable it's also
336.919 -> healthier for us too
344.09 -> [Music]
363.23 -> [Music]
