Some foods are rising in price dramatically due to climate change. Socking away increasingly scarce foods can be an inflation hedge. Olive oil supposedly went from $300 per wholesale unit to $1,000. I do know the bottles I paid $4.65 for are now $7.15. Will they be $10 next year. I don't know. Is it a good investment to put 6 bottles on the shelf? You can always eat it. 
There are index funds for every type of investment, for big companies, for small ones, for USA for Europe, for Asia for everything all lumped together. There are mutual fund companies with specialties, and ones that will take $500 to invest, or start with ten times that. There are ETFs, there are large brokers, and small. This is just to say it's a broad landscape. You can DIY, with often free online advice, or pay someone 3-6% or $2,000 to do it for you. I don't think SEC rules allow one to give advice unless trained in finance.
