The role of Tea in lipid-lowering and fat reduction
Has always been a hot topic for research,
Especially regarding the study of
Pu'er tea that has undergone special Fermentation processes,
Which has attracted widespread attention.
Can drinking Pu'er tea really
Play a role in lowering lipids and reducing fat?
The answer is yes.
So how does it work?
Let's explore together with Xiao Xin
How Pu'er tea exerts its lipid-lowering and fat-reducing effects.
Note: Most studies on the lipid-lowering and fat-reducing effects of Pu'er tea have been conducted on rodents (rats and mice) and cell lines, with fewer systematic studies on live animals and clinical trials. By using animal experiments to verify the lipid-lowering and weight-loss effects of Pu'er tea and studying the main active components and chemical principles in Pu'er tea that contribute to these effects, we arrive at the following conclusions:
Pu'er tea has a preventive effect against obesity
-Conclusion One-
Pu'er ripe tea shows better prevention of obesity than Pu'er raw tea made from the same raw materials;
The length of storage time
Is positively correlated with the effectiveness of Pu'er tea;
The preventive effect of Pu'er tea against obesity exhibits a dose-response relationship.
Pu'er tea has a lipid-lowering and weight-loss effect
-Conclusion Two-
Pu'er tea has a significant lipid-lowering and weight-loss effect on nutritionally obese rats,
With a dose-response relationship.
Pu'er tea shows better lipid-lowering and weight-loss effects on nutritionally obese rats compared to Green Tea and Fu brick tea,
And is comparable to the effects achieved through dietary intervention.
Additionally, experimental results also show that
Pu'er tea can significantly increase the activity of serum and other Antioxidant enzymes in rats,
Reduce the accumulation of lipid peroxidation products,
Improve the antioxidant indicators in obese rats,
Thus reducing the risk of atherosclerosis-related diseases in rats.
The lipid-lowering and weight-loss effects of Pu'er tea are superior to
The commercial weight-loss drug L-carnitine.
-Conclusion Three-
Experimental results show that
The total water extract, ethyl acetate extract fraction,
And residual water layer fraction of Pu'er tea all exhibit lipid-lowering and weight-loss effects on obese mice.
The lipid-lowering and weight-loss effects of the total water extract of Pu'er tea
Are superior to those of the commercial weight-loss drug L-carnitine.
The weight-loss effects of the ethyl acetate extract fraction
And the residual water layer fraction
Are better than those of the total water extract of Pu'er tea.
Therefore, it is speculated that the main active components responsible for the lipid-lowering and weight-loss effects of Pu'er tea
May be present in the ethyl acetate extract fraction
And the residual water layer extract fraction.
Pu'er tea can increase lipase activity and reduce the vitality and proliferation rate of preadipocytes
-Conclusion Four-
The lipid-lowering and weight-loss mechanism of Pu'er tea is explained both in vitro and in vivo.
In animals,
The primary functional components of Pu'er tea
Reduce the activity of fatty acid synthase in the liver and fat cells,
Decrease free fatty acids and serum leptin levels,
And increase the activity of lipase in the liver and adipose tissue
To reduce the accumulation of fat in the body,
Thus exerting a lipid-lowering and weight-loss effect.
In vitro,
After adding the functional fractions of Pu'er tea to preadipocytes,
They can dose-dependently and time-dependently
Reduce the vitality and proliferation rate of preadipocytes;
They can also promote lipolysis in mature adipocytes,
Reduce the number and size of mature adipocytes,
Thus decreasing the triglyceride content within the cells,
Exerting a lipid-lowering and weight-loss effect.
It is worth noting that
While this animal experiment can relatively accurately
Reflect the process of fat metabolism,
It is different from human fat cells and
Cannot fully explain the various Health benefits of Pu'er tea for humans.
These findings can only provide a reference,
Please view the experimental conclusions rationally.
