Herbs & spices: Cinnamon powder, nutmeg, ginger powder, cardamom powder, ground fennel, mint leaves. These herbs and spices are rich in antioxidants and anti-inflammatories: see Antioxidants in a Pinch (4 mins, 2019) by Dr Greger) and Which Spices Fight Inflammation? (5 mins, 2014).
Misc: Cacao powder, carob powder and vanilla extract. Cacao powder is health promoting.
Maximize antioxidants in every meal! Why? See Antioxidant Dynamics In Our Body; in particular, see the video How to Reach the Antioxidant "RDA" (3 mins, 2013). Keeping these videos by Dr Greger in mind, I try to maximize antioxidant value of all my meals through incorporation of herbs, spices and berries.
Vanilla extract vs vanilla essence: This article explains: "Vanilla extract is usually made by soaking vanilla pods in alcohol and water — with flavour taken up by the liquid ingredients. Vanilla essence is a synthetic — so it's made using artificial flavours and colours. Since it's manufactured, you will often find vanilla essence contains very little or no real vanillin. As a result, it's sometimes high in additional additives (e.g. colouring, flavouring, sweeteners, preservatives.)"
