moderation is the key!
Rich in vitamins, minerals and trace elements, certain foods are known to be particularly beneficial for our bodies. However, foods that are considered healthy can sometimes hold a few surprises, especially in terms of calories! In some cases, moderation is required, as eating too much of these foods can be harmful to our bodies. Find out about these healthy foods that you should sometimes avoid!
Rich in protein, fibre, vitamins and minerals, spinach also contains lutein, a carotenoid that helps prevent AMD. However, it also contains calcium oxalates, especially in its cooked form. Not everyone is able to assimilate them well, as our kidneys can sometimes have difficulty filtering them. For example, in people who are sensitive to it, oxalic acid combines with calcium in the urine and can form kidney stones. If you have kidney or urinary stones, gout or are taking blood-thinning medication, you should not eat too much spinach, rhubarb, green tea, chard, beetroot and sorrel.
2) Canned tuna
You can’t make a good salad or sandwich for lunch without adding a few crumbs of tuna? It must be said that this fish is rich in essential fatty acids. However, along with swordfish, it is also one of the fish that live in the most mercury-polluted waters. In 2016, 60 millions de consommateurs revealed its analysis of fifteen tins of tuna, highlighting even more the well-known problem concerning the composition of this type of product.
Arsenic, cadmium, mercury… Heavy metals can be found in them, which can be carcinogenic and toxic in excessively high doses. In pregnant women, the increased mercury level in tuna can be dangerous for the unborn child. A study has also shown that a high consumption of fish and shellfish contaminated with mercury increases the risk of type 2 diabetes by 65%. Tuna should therefore be replaced by fish and shellfish that contain less mercury (mussels, prawns, salmon, mackerel, etc.) and ideally should not be eaten more than once a month.
3) Brown rice
Although not necessarily lower in calories or carbohydrates than conventional rice, brown rice is often considered one of the healthiest foods. It provides more fibre and minerals than white rice and has a stronger flavour. Because of its high nutritional value (which is better preserved by steaming than by boiling), it is becoming increasingly popular. However, brown rice has one major drawback: like tuna, it is full of arsenic. While all rice contains some arsenic, brown rice contains more because the grain is unrefined and therefore intact. Ideally, no more than two portions should be consumed per week. The region of origin of the rice is also important: rice from California, Pakistan or India will contain a third less arsenic than others.
4) Brazil nuts
Brazil nuts provide essential fatty acids, protein and fibre. Or selenium, which helps fight free radicals that cause cell ageing. However, in excess, this trace element can cause great fatigue, nausea, diarrhoea and even hair and nail loss. It is therefore best to limit your selenium intake to a maximum of 8 nuts. It should also be remembered that this type of nut tends to go mouldy quickly. The mould is very toxic to the liver. So only buy small quantities!
5) Seaweed, healthy food par excellence?
Seaweed is a very trendy food and is becoming more and more popular on the menu. However, although they are said to have many beneficial properties, it is also important to remember that they contain a high level of iodine. Many people suffer from iodine deficiency, particularly due to the use of non-iodised salt. This can lead to hypothyroidism with its associated symptoms (fatigue, depression, poor memory, overweight, coldness, etc.). However, for certain people at risk, ANSES recommends the greatest caution. This is the case for pregnant or breast-feeding women, people with thyroid dysfunction, renal insufficiency or heart disease, who are advised not to consume it.
6) Red meat
For a very long time, red meat was synonymous with good health. However, we are learning more and more about the effects of excessive meat consumption. Besides the risk of iron overload if our body already has too much, meat is also rich in saturated fat, but also in sodium in the case of processed meat. All of these harmful components in meat can lead to cardiovascular disease and cancer and increase the risk of death. If you like meat AND your health, eat it no more than once or twice a week
